I need to replace a length of lead piping and replace with 22mm copper pipe, then branch off from the 22mm pipe to 2 sinks (bathroom and downstairs to kitchen both 15mm) and up to hot tap on bath, 22mm, all hot water pipes only.
here who know what they are talking about, i am thinking of using a mixture of copper and hep20. I gather they can be conbined. Copper for the 22mm run from the lead to the bath tap, and hep20 for the 2 run offs to the sinks. One of these run offs to the kitchen has to run down through the floor and bend around a corner, hence the use of hep20. I intend to use compression joints on all connections for simplicity. Do this method sound ok, and what do i use to connect the lead pipe which i think is 3/4 inch onto a 22mm copper pipe. Thanks for reading, i hope you can give me some advice.
Just for background, my parents are having a central heating system from Warm Front, but they will not replace the lead so i am trying to save them some money and do the job for them.
