Can a Boiler Lose Pressure Without a Leak?
As pressure rises in a boiler, the pressure release valve should be able to determine when the pressure is too high. This way it would release pressure so as to lower it. Unfortunately, however, a faulty PRV could see your boiler lose pressure and this could occur fast. Again, the fix here is not DIY friendly and requires a professional. Faulty ...
