  • Why change gas pipes from 15mm to 22mm? | DIY Doctor UK

    Jul 20, 2010 · I thought maybe that all new boilers (ours has got to be 15 years old) may only take 22mm pipes, but then why not leave the existing pipes in place and attached a 15/22mm adaptor at the boiler end instead of having all the floor boards up to replce the 8 or 9 metre's of pipe we have. Any advice appreciated. Thanks.Get Price

    Apr 22, 2021 · But I can understand the OP wanting to avoid upping the pipe size if he can. The existing set-up most likely doesn't meet the 1mb but it's apparently been OK for 10 years.
