Diaphram tank

Wayco Wayne

to check the pressure on the tank is with no water pressure on the water side. If there is no valving that lets you do this you will have to drain the system and take the tank off to check the air pressure. After you go through all of this trouble, be sure to re-install it so you don't have to drain the system to check the tank ever again. The simplest way to do this is put a ball valve with a drain cap on one end, so you can shut off the tank from the system and bleed off the pressure through the drain cap, and then check the pressure. A diaphram tank should be checked at least once a year. WW

diaphram tank

I have an investment property that I just purchased. The property has a gravity hot water system with a diaphram tank in the rafters. Here is my problem. I checked the gauge, and cold it read 12lbs. (is that the correct reading for a cold boiler?). Anyway, in no time, it was pushing very close to 30 lbs so I turned it off. I kept adding and releasing water to I could at least get the furnace to work and get some heat in the house. The problem is that the gauge reads 0 and when I turn it on, the system works but run in the 25PSIG range which I feel is too high. I asked around and some people told me that my diaphram tank may be full. If this is the case, do I empty it completely and refill it? There is no gauge on this tank. I am still a little unsure of how this all works together. Any advice would be greatly appreciated. Thanks in advance.

the diaphragm has ruptured. Drain the pressure from the system and check the pressure in the tank. Most likely it's 0. If you get water out of the snifter valve the diaphragm is definitely shot. Otherwise you can try pressurizing it to the system cold fill pressure.
