I purchased and installed an outdoor faucet similar to the attached last fall. I also have a water shut off valve inside the house which was closed all winter so no water at all was in this faucet.
Now that it's spring, I opened up the interior valve and I'm getting a light but steady stream of water out of the faucet when it's closed. The faucet is one of those that goes from closed to fully open in a quarter turn of the handle.
I've checked it over and can't see anything that could be tightened. Since all of the mechanism is internal, there's really nothing to tighten that I can get to without completely taking it apart.
Does anyone have any suggestions or did I just end up with a bum faucet?
