underfloor heating leak??

SycoLTH

Hi,

I've installed underfloor heating in an old bungalow at the start of 2022.

At the time I was told to keep the pressure around 1.5, and that's normal to let some water in the system every now and then.

But it's the second time in 2 years that the pressure drops slowly under 0.5. So is that really normal? Or do I actually have a leak?

What do you think?

How big of an area? It can be normal on a new system as it purges small amounts of air left behind.

I presume you pressure tested it before pouring the floor.

I have no idea if it was pressure tested, I didn't know anything about it and trusted the plumber to do everything.

It covers about 150 SQM and it was installed July 2022.
