Hi. Pretty sure the leak is coming from the valve, not above.
Could it be that the valve is not quite tight enough? Didn't want to adjust it in case it stopped the valve from releasing water when/If it actually needs to.
There is water regularly dripping from the valve above my boiler. I assumed it was pressure related, but not sure how to confirm this as there seems to be no pressure gauge either on the boiler or in loft by expansion tank. Any advice on what I should check greatly appreciated.
