Wega Mini Nova using TONS of water.

[walt_l]

For the last several months it has seemed my wega mini nova has been using excessive amounts of water. It is plumbed using an flojet pump on a five gallon water bottle.

This weekend I was out of town and marked the water level before I left. When I returned the water bottle was a gallon and a half lower than when I left and not a single shot had been pulled. Pressure stat is replacex regularly and teflon tape is used. I did notice a water drop or two on the large nut at the top of the group head.

What do I need to check/replace to stop this water consumption?
