Hi all, Thank you for your responses and advice. Murray, The steam and hot water taps are on my to-do list, although I don't think they are currently leaking, they could do with a touch of grease and maybe a descale as well. Thanks for the advice regarding o rings :).
Mike, the boiler was performing like this before replacement of the safety valve, with an audible hiss of steam. I managed to remove and replace without having to remove anything else by using a set of vice grips instead of a wrench to stabilise the joint. Since reassessing, it seems the new valve had a slightly longer threaded section, and was bottoming out on the joint before fully compressing the teflon gasket. Rookie error I guess! For the meantime I've just added a second gasket to bridge the gap. On the upside, the boiler is now much more stable only calling for extra heat every 4- 5 minutes. Thanks again, I'm sure there will be more advice needed along the way! -Will On Thursday 18 July 2024 at 16:54:35 UTC+1 Murray Roblin wrote: > Hi Will. > I had a similar situation, addressed, partially, by replacing the > overpressure valve and the valve seat on the steam wand.
