Good luck.

As easy thing to try is tightening the drain plugs on the pump. These were loose on mine and it drove me crazy until someone on this forum told me about them. I didn't even know they existed. Anyway on my pump there are two drain plugs, on the left side of the pump as you are looking at it head on. They have little o-rings in them, and they just tighten by hand. My pump brand is Pentair, your arrangement may be slightly different, but in general they are on the side of the pump, towards the bottom. Just one more easy thing to try. Good luck.
