Leaking isolation valve after depressurisation of boiler

Tb9g · Feb 23, 2019

Hi

Need some advice please, my boiler dropped pressure so I attached the filling loop to the Tribune cylinder and added some water to rectify the pressure issue. Pressure is all good on boiler and CH is working, I now have a constant drip from the valve. Are these easy to replace? Any assistance would be appreciated as I have had to stop the water into the property.

Not bad have to drain down but just two compression nuts to undo and tighten

Thanks for the speedy response, I will pop down and pick up a valve from Screwfix and give it a go

Make sure you get the right filling loop type valves

Complete novice here, I assumed they may be generic. Guessing that’s not the case?

There are valves out there not designed for heating temperatures. Plus you need a check valve so the heating water can not get back into the mains water

That’s actually the one I was looking at more by luck than judgement though. Anything I need to be mindful of when removing /replacing my existing one?

Yes turn off mains water and drain the heating down a little. If you’re confident you could relieve the pressure by bleeding a radiator then snatch it. Just ensure that the check valve is in place and the arrow pointing the right way
