Radiant System with Small Leak and Geoloop Leak Seal or other leak products

We have a two zone radiant system in a house from 1953. We have a newer TriangleTube boiler with two newer Taco pumps.

There's copper tubing in both zones, some in the floor and some in the ceiling.

This year we started to lose pressure on the floor zone and pressure dropping to 5-8 psi.

If I fill the system after a while pressure drops. I can refill, but eventually pressure drops again.

I absolutely love the radiant system, but would rather not dig up concrete floors to patch the leak. I was curious if Geoloop Leak Seal or other leak products are effective.

    Worth a try. Check out this product specifically for hydronic systems. Easy to install if you have a boiler drain. or other hose connection.
