Would you Recommend Using a Leak Stop Product.

I designed and installed a hydronic heating system a couple years ago. It one zone with 4 loops using a TT PS 60 boiler. I have a very small leak somewhere I lose 2 psi every-other month. I don't use the auto fill valve, I add water manually. I've checked over this system 10-15 times. It's dry, so I'm thinking about trying some heating system stop-leak but, I'm concerned about the small passage for water thru the shaft of my Taco VDT circ. Has anyone used this type product with a Taco circ. Any suggestions would most appreciated. Thanks

Personally I wouldn't use it. Unless there's something new on the market better than what they had. It reeked havoc with the systems, plugging vents anything in its path..

The leak may be evaporating before it shows up?

I would try leak-detection dye first. The leak will show up when exposed by an UV lamp. Kits are available - be sure that you get the version for water, not for Freon.

Yeah... you don't wanna clog that thing all up with glue...

Check the schrader valve on your expansion tank.
