Chromalox hot water furnace pressure issue

Paul_70

Hi,
I have an in-law with an older Chromalox hotwater furnace model EDB 20-1, used to heat a house extension. The system had not been flushed in a long while which we finally did recently; it was leaking at a few places. Replacing the pressure regulator with a (equivalent type), an Armstrong C-11 water pressure combination regular valve reaches is pressure valve limit and water is let out constantly. All the air was bled out of the system and the air pressure tank was permitted to stabilize with a new water level after it had been fully drained. We do not have the service or user manual for this older furnace anymore. I am a good all around do-it-yourselfer... home projects and utilities repairing type person, but I do not know much about this type of system.

Can anyone give me some clues as to what to do next, short of calling in an expensive plumber. Family circumstances there have forced the couple to sell the house and they have little money for expensive repairs. I think this problem can be solved without too much difficulty but I need some guidance /eg check list of things to do and try; perhaps a lead to a good internet site that can explain how this type of system works in general.

Much appreciated,

Paul

Check the basics. Is the make up water valve leaking by? Was the Temperature or Pressure relief valve replaced within the last 5 years? Is the CORRECT TP Valve installed?
Does the expansion tank function?

How much do you like the in-laws? The last I checked, plumbers are cheaper than hospitals and building contractors. Use the Find a Professional option at the top of this page and get yourself some good help.

I am not being a complete jerk for no reason. If the system has not been maintained properly, a professional is worth the money you spend on him or her. They have the correct tools and the training to not only fix what is wrong with the system, they should also be able to tell you whether the system should be fixed. If this system uses a flame to heat the water, the burner adjustments and chimmney requirements are things that most people should not be adjusting. Sleep soundly and call a professional.

Good Luck
