hello.
I have a weil mclain CG Boiler (CG-5-SPDN Model) and my pressure relife valve is leaking water. It first started with a few drips about 3 weeks ago, and eventually right now it has become a slow stream of dripping. For time being, i used some PEX piping to route into a pump to avoid the floor getting wet. The water that it leaks out is hot.
I have a fairly complex system, i feel… i bought the house like this, and it has 4 zones like below,
There is 1 expansion tank for the boiler itself, and there is another expansion tank for the water heater. However, the expanion tank to the boiler itself is upside down, not sure if this is a problem. The boiler gauge itself has a 30 psi.
I am posting the pictures of my setup. I suspect it may be be a bad expansion tank , and also sediment on the pressure relief valve. I have already bought the replacement of the pressure relief valve , but the space is so tight , i may end up calling a professional to help me with it. However, i want to do some basic troubleshooting, so if i do call a professional, i know what i am dealing with.

I have a fairly complex system, i feel… i bought the house like this, and it has 4 zones like below,
- 1st floor
- 2nd floor
- Sunroom (Radiant heat)
- To the water heater

- Can you let me know how i should troubleshoot this? The pressure relief valve is the one towards the back, with a WHITE PEX pipe (I installed it for time being just to route water away)
- Can you tell me how to troubleshoot the expansion tank?
- Can you tell me what is the best way to drain (i think its also called bleed) the system to replace the expansion tank and also the pressure relief valve? (If needed)
- How old is my boiler and how old is my expansion tank? They look fairly new.
