Thanks is the above flexi not suitable to pipe a toilet up with, because its not wras approved. Cant see the purpose of it, when do you need a flexi with and iso valve on, on a heating system?
Have you tried BES? Do plumbing items need to be specifically WRAS approved? I thought that just meant they'd given someone in WRAS a backhander or sexual favours? What if it has a KIWA approval or suitable BS?
