It is not always practical or possible to carry out a permanent repair immediately on a pipe that is leaking, however some kind of remedial action must be carried out right at once. So below is a way of carrying out a temporary pipe repair:Firstly isolate the water supply to the pipe concerned and drain it down. A temporary repair can be effected until a permanent repair is possible. There are two simple techniques which can be employed for this:1). Pipe repair using hose.Take a piece of rubberised hose big enough to go around the pipe. Cut it along its length and put it over the damage. Fasten with at least three jubilee clips. One in the centre and one at either end. By tightening these sufficiently, you should be able to seal the hose against the pipe so that no further water escapes. A Coulsdon Plumber carries clips for pipes.2). Pipe repair using epoxy putty.This is a two-part system that sets hard and sticks most materials. Clean the area of pipe either side of the damage, with a very slightly abrasive like a scotch pad. The putty may not work otherwise. Mix the two components together as detailed in the manufacturers instructions. Press the mix onto the damage and smooth it out. Make a check to ascertain to see what thickness is needed and also how long it should be left before the water will be able to flow through the pipe again.Permanent repair.Whilst a temporary repair can overcome the immediate problem, it is always advisable to make a permanent solution as soon as you can. Coulsdon Plumbers can carry out the work. Make sure to drain the damaged pipework. Cut out the bad section and fit a new length of pipe with compression or solder fittings at each end.
