      I have a leak in my system, SOMEWHERE! I cannot keep 12 lb. full pressure in the system, and cold water is constantly flowing into the system through the relief valve. When running, I get about 8 lbs pressure. There is no trace of a leak in the floor or outside the house. The floor is a concrete slab. QUESTIONS: 1. How can I find the leak? 2. Is there a good sealer like for auto radiators? 3. Any suggestions????Thanks very muchKirk Gibson (no, not that one!)

As for sealing the leak you may check out some kind of boiler seal, but be carefull these can stop up internal parts of your piping system and the boiler.Ken

      Hi. My name is Shane EDilley, and I am a 14 year old student at River Ridge Middle School. I am doing a report about Radiant Hot Water for science class, and I was wondering if you could send me some information about it. Thanx.
