Thanks guys...

Hi there, It's finally time for a new boiler (Vaillant heat only open vent). We have a recommended installer but he is only licensed to work on boilers and pipework. However, we also have a gas fire and hob (though these are fine and won't be involved in the work). Is the installer allowed to...

Thanks for this guys. We did it last night using ptfe tape and lsx. Got it done quickly and with no leaks. Cheers, Jo

Hi Guys, I'm changing a hot water cylinder with a mate (it's his house). I've done one of these before (my own) and used ptfe tape on the threaded fittings. Worked ok, but had to remove and refit the cold feed fitting after it leaked a bit first time. I've seen this liquid ptfe stuff and it...

Hi everyone, I have an indirect vented cylinder for hot water and an unpressurised heating system. All has been working well, but over the weekend the heating comes on with the hot water. Even if the programmer is set to hot water only. Am I correct in thinking that this is probably due to a...

Hi guys. I'm changing my central heating pump but am unsure of which make to go for. I've got an old Grundfos that is making funny noises so I reckon it's time for a new one. I've heard that Grundfos and Wilo are pretty good. How about Myson pumps? Are their cp53 or cp63 pumps any good? I've...

Thanks guys. Seems like everyone has their own choice for what to use on these. I'm still not quite sure how tight I should go with these fittings though. Presumably once they're connected to other fixed pipework I won't be able to tighten them up any more?

Hmmm - never used hemp before... how tight do I have to tighten the fittings up? I'd be a bit wary of overdoing it and distorting the cylinder.

Ok, I know they're threaded. So what should I use on the threads? lsx? loctite 55? something else...?

Hi Everyone, I've got a leaking hot water cylinder (vented) and want to change it. I've done a reasonable amount of plumbing in my time but never one of these. I don't know how to seal the threaded fittings. Can I use fernox lsx or is something else better. I've been told that loctite 55 string...
