I have a 3/4" bore lead water supply pipe. I have cut it back to where it enters the house. I wish to feed my house system via a whole house water filter, including the combi boiler. The static pressure is just under 4 bar. Should I use 22mm pipe to and from the whole house filter? I also wish to T off an unfiltered supply for the toilets and garden, should I T off before the filter in 15mm?. The filter suppliers say I need to get a qualified plumber to fit it, but even if I do, I need to lay in the pipes before I get to that stage. NB The filter is not just because of the lead pipe, it is for chlorine etc. Advice welcome. Thanks. Matt
