An important part of Gas Safety Week is making sure people know exactly what to do in the event of a gas leak.

Every year thousands of people across the UK are diagnosed with carbon monoxide poisoning. This highly poisonous gas can't be seen, smelled or tasted, but can kill quickly and without warning. Early symptoms of carbon monoxide poisoning include headaches, dizziness, nausea, breathlessness and then eventually collapsing and even loss of consciousness. As an invisible gas, carbon monoxide can be extremely difficult to detect. However there are ways that you can determine whether an appliance (such as fires, heating boilers, water heaters or cookers) are dangerous. These include:

  • The pilot light continually blowing out
  • An orange or yellow flame rather than a blue one
  • A discoloured scorched area on an appliance
  • A musty smell or signs of soot
  • More condensation than normal on windows

If you see any of these things, whatever you do DO NOT try to attempt any sort of repair work yourself - you could only end up making it worse. Instead what you should do is call the free emergency gas number on 0800 111 999 and follow their instructions. As soon as you suspect a leak, don't start any flames or operate electrical switches. Make sure to put out any fires, open doors and windows to air out the rooms, keep people away from the area and turn the gas off at the control valve. 

Once you've made the call, a trained operator will log a number of details onto a computer. The kind of questions they'll ask you are:

  • Your name and phone number
  • The address and postcode of the suspected gas emergency 
  • How many people are at the property 
  • Where the smell is most noticeable 
  • How long the smell has been noticeable
  • Are any neighbours affected 
  • Any special circumstances or access information
Following that you'll be asked a number of questions to determine the severity of the situation. This information will be recorded and sent off to an engineer to take action if its required.

Flush only once. If it's not flushing the first time, don't flush again. This will cause more water to be pumped into the toilet bowl. If the toilet becomes clogged the first flush will not cause the bowl to overflow, but the second flush might!

Put on a pair of rubber gloves. Toilets are inherently unsanitary places to work, but a good pair of rubber cleaning gloves will protect you from any germs within. If you can see the cause of the clog, remove it from the toilet if possible.

Protect the floor. What's worse than a clogged toilet? An overflowing toilet. Minimize the potential damage by placing newspapers or paper towels on the floor to soak up liquid. Besides, minor splashes and spills are bound to occur when you're unclogging the toilet. The paper will make for easier clean-up later.

Make sure the water supply to the toilet is off. It should be located right behind the toilet, and looks like a regular faucet knob. Do not shut off the supply for the house, since this will prevent others from using water. If the water is off to at least the toilet, this will prevent the bathroom from flooding.

Ensure that the bathroom has good air circulation. Turn on the ventilation or open a window to minimize foul odours, and to protect against potentially toxic fumes from any chemical products you may need to use.

Plunger Method

If you know there's an object (such as a child's toy) causing the clog, skip the plunging and go straight to another method.

Be sure to use the right plunger. It is important to use a large heavy-duty rubber plunger, either the ball-shaped type or one with a fold-out rubber flange on the bottom which forms a seal. Do not use the small cheap suction-cup type of plunger––these will often not work. Remember, the larger the plunger, the more force you can apply down into the clogged drain. The plunger should have a shape which ensures that the water you force out of it when you push down does not shoot back up into the toilet bowl instead of pushing into the drain.

If your plunger is not making a tight seal, try wrapping an old rag around the end of the plunger and press down on any leaks. Run the plunger under hot water before using it. This will soften it up, which will help with creating a seal.

Insert the plunger into the bowl and press down firmly but slowly. Make sure you're covering the hole completely. The plunger should be submerged in water to be effective. It is important to be pushing and pulling with water, not air.

Add water to the bowl if necessary. Sharply pull up on the plunger to create suction in the drain, then push in to create pressure. Remember, the clog got jammed going in, so don't be too aggressive with your pushing because you might just jam it further. It is more the suction than the pressure, constantly disturbing the clog in both directions that will gradually cause it to be loosened.

If the plunging eventually drains the bowl but the clog is still blocking a free flow down the drain, leave the plunger in the bowl and fill the bowl with water again. Fill it to the point it is normally after a regular flush. Then plunge again. Stubborn clogs might require you to do this a number of times.

Should plunging fail to unclog the drain, a wire coat hanger may clear the obstruction. This will generally work if there is an obstruction in the first few inches of the drain.

Unravel the hanger, twisting the top ends apart until they are no longer connected. (To avoid damaging the porcelain tightly wrap one end with a rag). Stick the wrapped end of the wire into the drain. Once the wire is in the drain, twist it, push it, and manoeuvre it in a circular motion to clear the drain

Plumbing Snake Method

Purchase or borrow a plumbing snake. A plumbing snake (also sometimes called a "flexible cleaning tool" or "auger") is a flexible coil of wire that can "snake" through the curves of a drain and get deeper than a wire can. The best snake is a "closet auger" which is designed specifically to clear toilet clogs without damaging or staining the bowl. A plumber would likely use a closet auger.

Insert one end of the snake into the drain. Push down, feeding the snake further into the drain until you feel an obstruction. Twist and push the snake through the obstruction until the water begins to drain

Snake in reverse, as it may become necessary to remove the toilet and run the snake through in the opposite direction. This is especially true with hard obstructions that may have been flushed by a curious child. If a hard obstruction is known, and you are not comfortable removing and replacing the toilet, contact a plumber.

Installing a tap will only take you around half a day, but you will need basic plumbing skills. Under current regulations you have to fit an isolation valve and a double check valve inside your home when you put in a new outdoor tap (see below for details). If you need to know more about the regulations talk to your Water Company or local council.

  1. Turn the isolation valve off if there is one on your cold water supply pipe where your new garden tap is to be connected.

  2. If there's no isolation valve, turn off your main stopcock. This is fitted on the pipework and normally found either in the kitchen or where the mains water enters your house.

  3. Finally if you can't find the stopcock, turn off the water authority's valve under the cover in the street or your front garden. You'll need a special long-handled spanner, available from plumbers' merchants. Once the water supply is off, open the cold tap on your sink until the water stops running and the system is drained.

  4. If you're installing a new tap you need to bore a hole through your outside wall for the connecting pipework. It's easiest to make the new connection near an exposed cold water supply inside your house - near the kitchen sink, for example.

  5. Position your outdoor tap at least 250mm above the damp-proof course. Then mark the screw holes where your tap will be.

  6. You will need a 15mm diameter pipe to connect the tap to the cold water supply inside the house. Position the hole for this about 150mm above where you've marked the position of the tap.

  7. Before drilling the hole, run the pipe through a piece of 22mm diameter copper pipe. This acts as a 'sleeve', which will prevent the pipe rubbing and water leaking out of the hole if the pipe bursts. When drilling, make sure the hole is wide enough to take the sleeve's diameter.

  8. Steadily drill through the wall with a heavy-duty power drill and a large masonry bit at least 325mm long. Take out the core bit regularly to clear the loosened masonry and let the bit cool down.

  9. With the supply turned off, cut through the cold water pipe directly below the exit hole you've drilled in the wall. Use a hacksaw or pipe slicer to do this and file the ends of the pipes smooth.

  10. Remove enough pipe to fit a T-piece connector. Connect one end of a short piece of pipe to the T-piece. Connect the other end to an isolation valve. This allows you to cut off the water supply to the new tap if you need to in the future. Isolation valves let you turn off the water to an individual appliance without having to turn off the whole water supply. You can get two types of isolation valve: a push-fit valve, which simply pushes on to the ends of the pipes, and a compression valve.

  11. Fit the valve the right way round or else it won't work correctly – there will be an arrow on the valve showing the direction of the flow of water.

  12. When you've turned off the water supply, mark the section of pipe that needs removing to receive the valve. Cut the section from the pipe and be sure to file the ends smooth again.

  13. Now slide a compression nut onto each piece of pipe followed by the olives. Push each end of the pipe into the fitting and tighten the compression nuts by hand.

  14. Use a pair of pliers to hold the body of the valve and tighten the compression nuts about three-quarters of a turn with an adjustable spanner. When you turn on the water supply again, check for leaks. Tighten the compression nuts a little further if you have to.

  15. Next you'll need another short piece of pipe to connect the isolation valve to a double check valve. Water regulations say you must fit one of these to your outside tap pipework. Double check valves stop water flowing back up a pipe the wrong way. This prevents contaminated water entering your drinking water supply.

  16. For a new outside tap the double check valve must be fitted in your internal pipework, after the isolation valve. Double check valves are installed in a similar way to isolation valves.

  17. After fitting the double check valve insert another short piece of pipe and an elbow. Then fit a length of pipe long enough to reach horizontally through the wall to the outside. When it's through the wall, cut the pipe to leave about 25mm protruding.

  18. Finally, you'll need to cut a piece of pipe that reaches from the pipe protruding from your outside wall down to the position of your tap. These pipes will be connected using another elbow joint.

  19. Connect all the parts together and tighten the joints with two adjustable spanners. You can tighten the joints more if they leak when the water supply is turned back on, but be sure not to over tighten.

  20. Drill the fixing holes for the tap's wall plate, insert plugs and screw the tap plate to the wall. Screw the tap tail into the elbow joint.

  21. Use plastic retaining clips for the pipes on the inside wall to stop the pipes vibrating and knocking against it. Then seal around the pipe hole in the wall with an expanding foam filler or sealant.

  22. Water resistant foam pipe lagging should cover all the pipework that is on the outside of the building to protect against freezing. This will be fitted after testing for leaks.

  23. Finally, turn the water supply back on and check for any leaks. Tighten joints if you need to and then you're ready to go!

electric shower

Firstly when you’re having problems with your electric shower don’t attempt to fix it, this is false economy – you’re much better off changing the item completely. Here are a few steps to show you how to change an electric shower. 

  • Step One - Safely take off the front cover of the electric shower box. There will be at least 1 or possibly 2 small screws holding this in place. Next, take off the front temperature and control knobs by pulling them straight off (this shouldn’t be too difficult to do). With the front cover off you should be able to see a valve on the water pipe going into the shower unit, it should have a screw slot in the middle of the valve. Turn this a ¼ turn either way and test the shower to see if this has turned off the water. You can use the control knob by temporarily re-attaching it to the shower to get the water to flow.
  • Step Two - When changing an electric shower, you must turn off the electric supply at the consumer unit (or fuse board as it’s commonly known). The fuses/trips should be marked but if they’re not, the 1 of 2 possible trips you are going to turn off will be either a 35 amp or a 45 amp depending on the Kilo-watt power of the shower. For a 35 amp fuse/trip, the shower should not be over 8.5 kilowatts. For a shower that is greater in kilowatts, the fuse/trip will be a 45 amp.
  • Step Three - The next step in changing your electric shower is to check that the electric has been turned off by either pulling the cord switch in your bathroom or the wall-mounted one outside. Run the shower and make sure that the running water isn’t warm/hot. With the electric turned off, you can put a notice hanging from the consumer unit to warn others not to turn back on.
  • Step Four - If the water is now off you can take off the water connection where it connects closest to the unit. Undo the electric cable connections and remove the unit, remembering to replace like-for-like in the kilowatt power rating of the unit (this rating can be found somewhere on the old unit, and on the front cover box of the new one).
  • Step Five - When you have connected the new unit to the electric cable and to the water supply, check the water flow through the unit first, then with the cover on the unit you can turn the electric fuse/trip back on. Go back to the unit and turn the wall-mounted switch or pull the cord on, turn up the thermostatic control on the unit and the water control knob to on. Your new shower should be working, but with the new shower unit you will have the manufacturer’s instructions in the box. Follow these carefully, and it should be safe for you to install.

When wanting to completely refurbish a bathroom, it can take a number of skills or tradespeople to complete the work. Firstly safely the water supply and any electrics need to be isolated, so that the de-commissioning of the bathroom suite can begin. Then the walls and ceiling can be torn down if required, with the rubble and old suite also having to be disposed of in a responsible way.

Following that any required alterations to the water supply pipes can be performed, as well as sorting out electrical wires, flooring and tacking new plasterboard walls and ceiling.

Once the finish plaster coat has been applied and dried, the bath can be made up and fixed in place. Once carpentry bits such as architrave and skirting boards can be fixed, then the tilling can take place. After this the rest of the plumbing can be completed and the electrics finalised, woodwork painted then if floor covering is going to be used it can go down (however if the floor is to be tiled this should be done before the woodwork).

So if you can organise the different trades or do all of this work yourself if you have the relative qualifications or the relative expertise of experience then managing the project yourself can save you a considerable sum of money , but it can take a considerable amount of time to organise and manage the project .

With a bathroom fitting company that can cover all trades and manage the project it might seem quite costly to begin with, but in the long run if you personally have not managed such a project then it might be advisable to employ such a company. But only after researching them through areas as “county court judgements”, “trading standards” and previous clients that have had similar work done.

Q: What do I do if my radiator panel is leaking?

This is due to the metal corroding/rusting, and the first sign of it happening is that the floor under the radiator gets wet when the heating is on. The first thing to do is to turn off both radiator valves to stop any more fluid being lost from the pipe system, which can affect the boiler and the rest of the radiators. Place a container under the radiator to catch any more drips of fluid.

If you don't have any plumbing knowledge it would be more cost effective to employ a qualified plumber/heating engineer to do the work required - the immediate emergency has been dealt with, and you can afford to get some quotes for the work to be done. It shouldn't cost an arm and a leg, as radiator panels are readily available for most plumbing merchants if it's a standard style (i.e. a flat straight panel, not once that has been bowed for a curved wall like a bay window). So for the cost of the radiator panel and a few hours' labour time, the work should be completed to a satisfactory level.

For those of you who feel they have good mechanical experience and the correct tools, then you may want to attempt it yourself. Firstly you will have to measure the width and height of the radiator panel, and determine the style of radiator. If you're not sure, stand as close as possible to it, look directly down at the top and take a photo of the top edge. Show the assistant at the plumbing merchant and they'll be able to give you a similar one.

Once you have purchased the radiator you will need to drain the old one and dismantle the fittings. The tools required for the change-over are a masonry drill and drill-bit of the appropriate size for the wall plug you will be using (red wall plugs and a 6mm masonry drill-bit for example). Use pozi-drive screws rather than slotted head ones, as there's less chance of the screwdriver slipping. When using the driver, the screw should be at least an inch and a half to two inches long for large radiators.

For plasterboard walls a toggle bolt is one of the many fixings suitable for this type of wall. You'll need two adjustable spanners, a radiator bleed key and possibly a radiator valve key (this looks like an oversized Allen key). With the two adjustable spanners, one is used to hold the top of the radiator valve (with the head taken off) to stop it rocking on the pipe when you undo the nut to panel connection. For draining and disconnection, if you have a combination boiler turn the heating controls off so that the heating system cools down before starting on the replacement. Then after changing the radiator you will need to repressurise the system to 1 Bar for up to 10 radiators. If you have a standard or back boiler the heating controls still need to be off, so that the pump is not running when you refill the exchanged radiator.

Before starting to drain you might want to put a bin liner on the floor with an old towel on top to catch any spills you might get under the radiator valve. When the radiator starts to drain from the nut you will need to open the little air bleed at the top on one end to allow all the fluid to drain out. When this has finished, again put a bin liner and old towel under the the other radiator valve. Now you can undo both valve-to-panel nuts all the way.

With these nuts undone, and depending on the size of the radiator you will have to gently move the pipes with the valves on towards the wall to enable you to put your thumb over the hole that will be there on the radiator. Lift the radiator off the brackets, keeping your thumbs over the holes and the radiator vertical so that it can be taken to a safe area to drain any sludge that occurs at the bottom of the radiator down a sewer drain.

The new radiator can be dressed with the new fittings for the top and the old fittings at the bottom. As for the joining of the new radiator and valves, it will have to be hung on new brackets. Then you can join the valves and the panel together via the nuts, again using the two adjustable spanners to do up the valve nuts in the same way you undone them. Make sure that the new air bleed at the top of the radiator is shut, and open both radiator valves at the same time to allow the pressure from both pipes to refill the radiator panel. You can then bleed the air from the valve at the top at one end until water comes out. For a combination boiler you will need to refill the system to 1 Bar, via the filling point directly under the boiler. With the pressure obtained turn the filling point off. With a standard/back boiler this will self-fill from the little plastic container in the loft. With the radiator bled of air it will be safe to turn the heating controls back on and get the radiators hot again.
