Hello all,
I need to replace the supply to my house and have a number of questions.
I had a new water meter fitted last year but the water board fitted it to the existing lead pipe which comes into my house approx 3m and then continues in 15mm copper.
Since I am in the process of renovating the house I think now is a good time to replace the copper and lead pipe with MDPE as although the pressure is fine the flow rate is abismal and you need a good flow rate for a combi.
So my questions are:
1) I am going to need the water board to connect to the meter end but what size MDPE do I buy? I'm guessing 20mm or 25mm or does it not matter? 25mm would be better for flow but can it be connected to ther water meter?
2) The other end will obviously be a stopcock but what is the best one to buy? I've read a few places that there are different fittings for MDPE so do I buy ones with grabrings or without? What are the best fittings?
3) It appears that most stopcocks have MDPE connections of 20/25mm and copper connections of 15/22mm but which copper connection is recommended? I would assume there is no problem with a 22mm connection?
4) How you fit a MDPE stopcock I guess would depend on which one you buy, but am I right in thinking that you cut the pipe to length, add a pipe insert (to strenghten the pipe) and then assemble the fitting with or without grabring (if present)? Are there any problems to watchout for or any knacks to doing these fittings?
Any help is appreciated.
Thanks
