Hmm... I have a problem with the furnace over the past couple of weeks and I thought nothing of it until now. I know I should go call up a plumber or someone like that but AT members have solved many a problem for me so why not try again 
.
Ok, it is a natural gas furnace and its about 50 years old and the house is sixty years old. There is a pressure gauge, a water line gauge (a glass tube with water in it... the water level goes up as pressure rises apparently), a "cut in" switch thingy, emergency gas burner on/off switch, and two faucet things that lets water out.
The pressure gauge goes up once the water line gauge is full and from my observations, it goes up when the heater is working. So usually during the winter, I would have to dump out a bucket or two in order to keep the water line level two-thirds full once daily. Slight annoyance.
Well, everything was fine (normal, rather) with the furnace but after this winter, the pressure in the water gauge and water line gauge goes up very quickly when the heater turns on. Loud clanging sounds come from the pipes (I think) and I usually have to go release water from the one of the two faucets twice a day. Now its becoming a problem but I thought it would go away.
April comes around and its still here... well I thought I'd get smart and turn the damn thing off using the on/off switch. The furnace is no longer running and I don't it need it to but the water level continues to rise by itself. When the pressure is high, water starts coming out from the radiator/heater valve (?). and then I have to run down to the furnace and dump out water... oh now I have connected a ten foot tube from the faucet to the toliet. Before, when the switch is "off" nothing would happen and the water pressure/ line level would stay put but no more. I am wasting water and time... any suggestions/fix? All comments are welcome and TIA!
