Hi Everyone
I have a WEIL MCLAIN BOILER firing two zones, Amtrol/Extrol model 30 expansion tank and hot water heat. I was getting some water flow from my releif value. I tapped on the expanion tank noticing it sounded like it was full of water. Guess the diapham must have busted. So I replaced the tank with the same exact model I had but noticed the pressure which should be at 20 PSI keeps creeping up. So I keep letting some water out to bring down the pressure but it keeps sneaking over 20 PSI. I do not want to let too much water out of the system but I think the system automatically repenishes any water loss it self. Any suggestions on how to keep the temperture at 20 PSI?

First things first, you want to make sure all of the air that gets trapped in the boiler is bled thru either auto vents or thru Manuel vents located on the radiators, if that does not stop the pressure issues then you will need to check the reducing valve, this is located where the cold water supply connects to boiler.
Not all look the same however the most popular are b&g and is red or gold and is in shape of a bell.
What you want to do is get the pressure to 22 to 25 psi and then turn off cold water supply and keep a check on the pressure, if it does not go up you will need to replace the flow control. You should never leave a boiler un intended without boiler water supply , so do the test while you are attending it.

I BLEAD THE AIR OUT OF THE RADIATORS, ALL THAT COME OUT IS WATER. WOULD REDUCING THE AIR IN THE EXPANSION TANK LOWER THE PRESSURE? THERE IS A LEVER ON THE BACK OF THE REDUCING VALVE (THE RED BELL TROM THE MAIN WATER LINE). WHEN I SLID THE LEVER I HEARD WATER RUSH INTO THE SYSTEM WHICH RAISED THE PRESSURE, SO I NEED TO LET WATER OUT TO LOWER THE PRESSURE AGAIN. I AM TRYING TO AVOID CALLING A PLUMBER DUE TO THEIR HIGH HOUSE CALL RATES AND MONEY BEING TIGHT. NOT TOO MUCH EXPERIENCE WITH BOILERS AND BEING IT RUNS ON GAS I DO NOT RISK ANY TYPE EXPLOSION. DO YOU THINK THE REDUCING VALVE IS THE PROBLEM? I AM NOT TOO EXCITED ABOUT DISCONNECTING AND RECONNECTING MY BOILER PIPES. ANY HELP WOULD BE APPRECIATED. THANKS TIM

Someone recommended I turn the Pressure Valve adjustment screw counter clockwise a half turn to see if that would lessen the PSI. By the way this is a Green colored bell not Red . It seemed good for the first couple of hours but then the next morning I noticed it was up past 25 psi. I want to see what it is when I get home from work today. It would usually get up towards 30 psi within a couple of days and now seems to be creeping up quicker. I am getting the idea that once I resolve this problem(if ever)I will be a Master Pumber as far as Boilers are concerned. Any other suggestions or help would be greatly appreciated with my on-going delema.
