I have recently purchases a 1952 home with the original oil furnace and baseboard heating. I am trying to find a diagram of how the system works so I can understand the pipes, tanks and valves that are in the system. What I think is a pressure release valve intermittantly leaks water. I have attached a PVC drain line to carry this water outside. Is this dripping normal?
If you know of any web sites that offer such a diagram, please let me know. Thank you for your help.
