Leaking geothermal Loop

[magnethead]

Hi There,

I was wondering if you could see the issues with this? I found a small leak of glycol from my geothermal loop, just behind the heat pump.

I think the glycol fill is supposed to last 10 years, but it would have trouble doing that I'm guessing even with a small leak.

Is there an issue with oxygen getting into the system too, interfering with the glycol?

 

Thanks for any information

It might be hard to spot the small puddle of green glycol in this picture but it is there.

Looks to be just coming from the fitting, not the ‘loop’ ( pipe ).

Has anyone tried simply pinching ( gently tightening ) the nut on the fitting(s) ?

Yes, you are right, it looks like the fitting, I asked the plumber again and he said something about it being hard to seal the plastic and copper together (The upper insulation is wrapped around copper pipe that goes directly to the HP)
