haha...it's joint where the PVC screws into my fresh water barrel. It drips every now and then when the pump is pulling water from the barrel. It doesn't when it's just sitting under the water pressure of the tank itself.

I also now hate unions. Is there a perfect way to know they are good. Two of mine leaked and they couldn't be in worse locations to reach. I've redone them and they are fine now but I put a union into everything...go knows how many leaks I will have!!!! It scares the bejesus out of me and all I've got going is my water change station.
