Hi, My wife and I had a new boiler installed about 18 months ago. It is a Munchkin MC120 Contender Wall Hung Boiler that is natural gas supplied. We are extremely happy with it and we think that it was well worth the price paid for it. I heard that it needs a cleaning once a year which...

I have a centurion heating system model gf9s06012up11j that is a couple years old. It just stopped producing heat. I see that there is a fault code of three red flashes. (Pressure Switch stuck open). What does this mean and where is it so that I can unstick it? Also ! the basic info on the...

Hi, I have a Cenrurion heating system Model #gf9s060b12up11j that stopped producing heat. I inspected the unit to find that it is giving a fault code of 3 red flashes. The chart on the cover states that the fault condition is: pressure switch stuck open. Could someone tell me what the pressure...

I did not mean to harp on this, but I was getting conflicting info. (JIMBO's reply, did make some sense). I do appreciate all the feed back from everyone. You can be sure that I will be investigating the expansion tank along with the T&P valve. :o

Gary Please clarify: "You need an expansion tank in the supply line." My previous posting stated that we had one installed years ago on the WH. I you stating that I have to have another one installed?

The PSI coming into my house is around 80-85 measured at the water spicket (awesome), but the T&P value was blowing water all over the cellar floor. We had an expansion tank installed at the WH years ago. Helped, but did not resolve problem. This weekend I installed a PRV off the main coming...

1). At what water pressure should a T&P valve start to open? There is about 80-85psi in the tank, when is starts to open. When it does close, it seals tight. 2). Is there a way to know if is starting to go bad? 3). Do they go bad? Weak spring ! 4). Are they easy to replace? 5). If I have...

TP valve on 40 gal hot water heater. BAD??? 1). At what water pressure should a T&P valve start to open? There is about 80-85psi in the tank, when is starts to open. When it does close, it seals tight. 2). Is there a way to know if is starting to go bad? 3). Do...

High water pressure Thanks ! I kind of figured that I would have to shut off the water and drain the system before checking the actual air pressure of the expansion tank. Could you explain how a pressure reduction valve works? I would not think that it works the same as a shut off valve. As...

Problem with high water pressure into the house. My problem is that my hot water heater keeps blowing water out of the safety valve. I have had a expansion tank added to the system years ago and thought it solved the problem,but the problem returned again. Talked to a plumber who stated to make...

Could someone please tell me what is considered Ie. low water pressure? less than 40 psi normal water pressure ? between 40 - 65 psi or high water pressure? above 65 psi into...

Do you have to take the pressure of the water off the expansion tank first before you add air to the tank. Sorry I have never done this before, but the concept makes since. (The pressure on the water side of the expansion tank should be equal to the pressure on the air side of the tank.) I am...

What is the max pressure that you can put on in the expansion tank? I was afraid of putting in too much and blowing the Diaphragm. Is the correct step for filling the air pressure to first take the water pressure off the tank?

I have been having problems with my gas hot water heater. The 40gal tank keeps setting off the safety valve (gals. of water on the floor). I have an expansion tank on the line and I tested it to make sure that there is not water coming out the air valve (none). I also tested the pressure in...

Do you think that turning the temp up will kill any bacteria, if infact that it the problem creating the musty smell?
