Re: Vaillant boiler pressure




DO NOT pressurize the system with air, and most especially DO NOT
pressurize to anything near 50#. First you will blow out the TPR valve
on the boiler, second, you stand to blow out the gaskets in the heat-
exchanger.



Agreed that 50 PSI is way too much, but I don't see a problem with
pressurizing it. When I test automotive cooling systems I pump them up to
about 3 PSI with a bicycle pump, I do this on top of the water already in
there, at which point it will usually drip from the leaky part instead of
coming out as invisible steam.
