Really? Downstream? The whole purpose of the strainer is to protect the pump valves.I have seen the strainer located downstream from the pump. If this is true in your case that drip could be your problem. Although as Kevin said it is normally mounted before your pump. Good luck with it.
I didn't say you felt it ok, I just try to help avoid confusion.Like I said, I've seen that. I didn't say that was the way it was supposed to be installed. I was simply suggesting that there was a possibility it was improperly installed, and that leak could be the problem! Really! Downstream!
