ONE: Firstly isolate the water supply, which is usually done by closing the drain cock underneath the kitchen sink. Once closed off, then open up all taps. As soon as the water stops flowing close them up. Doing this takes any remaining water below the level you’re going to be working at. Don’t do this if you’ve turned off the water to the taps with the isolation valves. If you have the isolated the water for the whole house you need to open up all the taps and flush all the toilets to drain the system. Water will just hang still in the pipework when all the taps are shut. However, the moment a tap is open or a toilet is flushed the suspended water will race down the pipe work to find you stuck under the sink and giving you a cold shower. Abbey Wood Plumbers use the correct tools and can also find any plumbing faults and deal with them.TWO: If your tap came with copper tails you should really consider replacing them with flexible connectors, as it is really going to save you a heap of time and trouble. The size of the threads at the base of your taps vary between 10mm and 12mm so either measure them or, easier still, take one of the copper tubes to your local plumbing merchant and ask for a flexi version. A Thamesmead Plumber professional can fit hoses.The easiest mistake to make is to bend the flexi connectors far too tightly. This causes the flow of water to slow to almost nothing rendering the tap unserviceable. Make sure that any bends in the pipework are made gently and the flexi hose needs to be kept still as the connector is tightened.
