pressure drop

sy

I just bought my first home. It has radiant heat. We got the system up and running but the psi keeps dropping. I searched and searched for signs of water leaks but none are visable. It takes maybe 2hours to go from 12psi to 0. I have to keep pressurising the system if I want to use it. Lucky for me its not that cold yet in Denver. Its going to get cold soon but I cant find out why the psi keeps dropping. I had boiler off and still losses psi, no sign of water around boiler. I thought about having to isolate each zone and figure out which is leaking but I had them all off and pressure dropped. Any suggestions??

Isolate the boiler and check it. May be the source of the leak. Dave Stroman is the man you want to page, he is in Denver. If the pressure is dropping as you say, you HAVE a leak...may be in the heat exchanger, the most common place if no work aas been performed. Is it WELL purged? Could air be escaping? Now were just grasping at straws.

visible water?

should I see a sign of visible water when I isolate the boiler and the pressure still drops? We purged thouroughly but I will double check that. Does your referal have a way to be contacted if I do need professional help?

Sy,

May we assume the floor is concrete and the radiant is in situ?

Would you know if the radiant tubing is copper, steel, rubber, PEX or plain plastic?

If the house has radiant heat in a basement slab - or, if no basement, the first floor slab, the pipe may be cracked in the floor and leaking under the slab/house.

If the leak is in any "hidden/un-accessible" part of the house, you have a major issue to resolve. If the home was inspected, the inspector may be accountable. If not, the former owner may have some responsibilities to make you whole.

Let us know as much as possible. We can help.

You can make a new post and 'page' Dave Stroman, or the phone book. I am pretty sure he has an ad in the Find A Pro section at the top, under 'resources'.

If not visible water, likely as Ken said...tubing under concrete that is leaking. What type of emitters do you have?

All the pipes are visible, the system was installed later in the life of the house. I have been tracing the pipes. I will try and isolate the tank this afternoon and isolate each zone to see which one might have the leak. The house was a as is property, no warranties. I will look up Dave Stroman also. Thanks for all the advice. I am trying to figure it out myself and found this great website to help. Really appreciative, Sy ps. I believe my heat emitters is baseboard style.
