    External condensate pipework.

    I can’t find anything in black and white for this. I usually go through the wall in 40mm waste and don’t insulate. Does 40mm now need to be insulated as well as 30mm?

    YouTube Video of pipework and pump

    Saw this last night and wondered about a couple of points. 1 You see the state of the pipework at 7m30s and at 7m54s he says he will recommend the customer gets the system flushed. I am thinking that the pipework shown is not like it throughout or surely no amount of flushing will help that...

    Removing two isolation valves in awkward spot (on heating pipework)

    Hi folks There's a couple of isolation valves on our radiator pipework (vented system). One started to weep a while back, but luckily stopped after a bit of tweaking. I've since learned they shouldn't be there, and so with some plumbing work coming up which will require a drain down, I'm...

    I have a Santon TP210B cylinder - I am told I have air in the system which is stopping the hot water from working. I have chopped into the existing heating circuit to add another radiator, but the hot water system seems to be suffering the most, which I cannot get my head around - This new...

    10mm pipework for cold water..why not?

    why is 10mm pipe not used for taps/toilet outlets? Why do I need the same diam pipe at the wash basin or toilet as I do at the bath or shower? I can't think of a reason why not so before I implement this, have I missed something that's not so obvious to a layman?
