Small Drip in Underfloor Heating Manifold

Postby dtsn » Mon Apr 13, 2020 8:57 am

I’ve just noticed a small drip in our heating manifold for our underfloor heating. It’s a very small drip (probably about 2/3ml per day). It appears to be an oil-like substance. The house is 5 years old and this has probably been happening for a few weeks. I now have a dish capturing all the drips but unsure what to do.


I could try to tighten the screw but I don’t want to make it worse - especially in this climate. So don’t know whether I should try and fix it or wait until we are all out of lockdown and get a plumber round to take a look. Any thoughts?

Simply Build It

Hi dstn,
I would suggest leave it until you can get plumber. It may well just be a case of tightening the nut but it could go wrong.
