I need to replace a long length of internal lead pipe to my water tanks in the loft (main water tank and central heating header). The house dates from
1902.The supply into the house is lead (which I will replace when funds allow) which is first fused onto copper (15mm) with the stop c*ck within the short copper length and then reverts to lead when it travels up to the loft - sunk into the plaster as originally installed. This is probably why no-one in the past has replaced it. But its only a matter of time till a leak occurs in this ancient lead piping.
What's to stop me replacing the lead section to the loft with the blue plastic water pipe - which is cheap, flexible and easier to deal with than copper. I saw a length of it in B&Q the other day which I think was 15mm bore 25m length for £19.99. I also suspect that it behaves better if the pipe freezes than copper - i.e.. not bursting.
Any views on this.
Regards, Roy
