Please bear with me...I know NOTHING about pumps/pipping, etc.
We bought a house with a 15 year old pool. I have NO info about the pool size (we are guestimating) piping, etc., other than who the installer is. I have called the installer and they have been NO help with any information about the pool or installation, claiming it was too long ago.
My husband checked the pool this morning and it was down about three inches!! Found out that a garden hose (not put there by us but was there when we moved in last fall) hooked up to a pipe coming off the filter is leaking. Turning the valve that is connected to this pipe opens it up and water gushes. "Closing" the valve still allows water (more than a trickle) to come out. Tightening up the valve just got part of the valve handle broken off.
Any ideas? Oh, it is wet around the pump/filter now because my husband took it out and cleaned it before I took this picture.
What I'm talking about is the broken handle/valve that you can see against the wall coming off the white PVC piping. The hose connected to it is painted yellow at that point, and it goes down to the ground and currently winds around the filter housing and it is the free end laying on the ground that is leaking water at this point.
