Where is it leaking?Bob Boan
You can choose to do what you want, but you cannot choose the consequences.0
No drips on floor goes from 30 lbs to20 lbs in half hour0
What make and model is the boiler? Did the sections come pre-assembled or did you have to put them together? Have you connected the system piping to the boiler? If so, are there valves between the boiler and the system?All Steamed Up, Inc.

Took jacket off no sign of water0
Could you still have some air in the boiler that is leaking?
Air can leak out when water would not....keep it pressurized for awhile. You can hear an air leak or use bubbles.0
?? Check your safety, could be going down the drain. If it's piped to the drain. Not the best solution but working with what info I got0
Yeah, maybe the boiler still has a bunch of air in it0
Yes, and that air would cool and shrink in volume a little and drop the pressure......or you have a small air leak that will not pass water....could be both.0
Water in some areas is 75F this time on year. A cold basement could be 60F, any chance water and any air pockets cooled off?
First do not assume your test equipment is leak proof.
Next you can continue with hydro test but without any air cushion, two drips out will make a dramatic instant pressure drop on a gauge. If it is slow, there is an air cushion or temperature gradient involved or worse a micro temperature sensitive crack. A vapor test could be done with refrigerant gas as a trace gas that is electronically detectable. Eliminate all low pressure controls, plug off all pipe openings and pressure up to maximum psi the mfg. recommends and use an electronic leak detector to check for trace vapor leaks. This might indicate where to look further.
Cracks, micro cast defects, are the hardest to find and may only leak at certain temps and pressures. If a leak is indicated and cannot be detected, than send it back for another one under warranty. I had two boilers on the same job I had to reject for casting holes. It happens. Cost me two days labor.0
finally found a tiny air leak with soap. now losing one pound per day what now0
Find the other one. What model boiler is this and what pressure are you testing at? 30? Pbec05 isn't in my vocabulary or Google's, for that matter. What is operating pressure of the system? Can you test with water instead of air and watch for a drip?0
Probably a Peerless EC-05. Think that’s and oil boiler. Push nipples, no gaskets.
Where is the leak at? Between sections? That’s a pretty larg eboiler, 20 gallons of water with steam. Wonder if hte factory has a procedure to re-torque the sections. Is hte supply and return connected? How is the pipe strain? Adequate swing joint and pipe supports?0
