water loss problem
« on: December 04, 2017, 03:02:49 PM »
Ok I have been checking the water level in my (new to me) Heatmor and it was going down when I had the pump running and just circulating water from the shop to the boiler (no fire yet). No signs of leaks at the boiler or inside the shop. I was losing a 1/2 an inch every 24 hrs (in the boiler). After two days of running on low I shut off the pump and closed the valves at the boiler and the water stopped going down. I checked it for two more days and the water level remained the same. I have brand new al pex lines in insulated pipes that are sealed together in the ground. No splices just one line up and one line back. The bladder valve has been closed for all of this. Could I have a leak in the underground lines or could it be just getting rid of air in the system? Any ideas are greatly appreciated.

A 50 plate water to water exchanger. Only one side of it has been hooked up so I could at least get water and antifreeze into the boiler side and get it going. The other side just has the plastic caps on it.

it has to be seeping somewhere. i would triple check all fittings.  my heatmor 400 never needed any water added. even at end of seasom, because of the bladder it would atill be full even afyer the water cooled down

Yes i checked all the fittings and around the Grundfro pump. Thinking it may be a bad or cracked line in the ground. :bash:

tee in a boiler drain and pressurize with a hose while isolated from the stove, then see it it drops pressure.

That is a good idea. Thanks EY

If you used compression fittings, check real close to make sure water isn't trickling down the pipe. If it is at the back side of the pipe it is sometimes hard to notice.

Yes I checked all a round the fittings but that is a good reminder. Thanks RSI.

I had to tie some paper towels around a fitting to detect a leak once.
