Advice to avoid plumbing emergencies
Snow and ice are predicted throughout the country over the next few weeks, which means some households will be faced with frozen pipes and leaks. However, prevention is better than cure, so here are a few things you can do to help yourself.- Make sure you know the location of, and have labelled, the stop valve on the incoming water supply main.
- Locate, identify and label all other stop valves, periodically checking that they are working correctly.
- Make sure you know the location of any drain valves by which you can empty your water and central heating systems once the source of heat has been extinguished.
- Ensure that all exposed pipes and storage system are properly insulated, particularly in the roof space or attic.
- In very cold weather take special care to prevent water pipes becoming frozen. If you have a storage cistern in the roof space it will be sensible to open the hatch to allow some heat from the house to help keep the cistern from freezing.
- Inspect your cold water storage system (tank) regularly and, if it is metal, make sure it is not corroding. Call in your plumber if there is any sign of a problem.
- Check the condition of flexible hosepipes to plumbed-in domestic appliances at regular intervals.
- Dripping taps and ballvalves are a sure sign that your plumbing system requires maintenance. To avoid them becoming major problems call in your plumber without delay.
- Have central heating boilers and other heating appliances services regularly (the IoP advises yearly servicing).

White Christmas?
If the weather experts have got it right, we could be seeing snow and icy weather in the next few weeks. Although the thought of a white Christmas may be appealing to some, it does bring with it the possibility of frozen pipes and plumbing emergencies. Over the Christmas period it may be difficult to find a professional plumber who isn't already inundated with work, but there are a few things you can do to help yourself. The Institute of Plumbing gives the following advice for frozen pipes and subsequent leaks:- The first thing to do is to prevent water passing the point of the leak - turn off your stop valve (stopcock). If water cannot be controlled immediately, open all cold water taps so that the pipework and storage system drains quickly. Do not turn on hot taps. Turn off the central heating system and, if it uses a solid fuel boiler, allow the fire to die out. Switch off the electric immersion heater, then call your plumber.
- If a pipe freezes, turn off the mains water supply at the stop valve inside your home (if fitted) - these are often sited under the kitchen sink. If there isn't an internal valve, turn off the water at the external valve. If the frozen pipe runs from a storage cistern and is not controlled by a valve, check that it hasn't split. If it has, empty the cold water storage cistern either by opening the cold water taps and flushing the WC or by siphoning the water from the cistern with a garden hose, then call your plumber.
- If the pipe isn't split, thaw it out by applying hot water bottles or by careful use of an electric hair dryer. Don't try to thaw it too quickly as there may be splits in the pipe which are not immediately noticeable. Never use a naked flame to thaw a pipe. Always start thawing a pipe at the end nearest the tap. If any part of the hot water system is frozen, there could be a risk of explosion if the boiler (or other heat source) is kept alight, so ensure it is turned off, or for solid fuel systems, extinguish the fire. Be careful because although water may be flowing from taps, other parts of the system may still be frozen.
