I have a 1 HP Waterford Systems swimming pool pump by Sta-Rite. I am a new, first time pool owner and I just made a huge error. I had my pump running for approx. 24+ hours with the valve shut off (therefore no water was going to the pump). It's been raining, so I've not been in the pool to notice that it wasn't moving water. As soon as I got in and nothing was coming out of the return jet, I jumped out and opened the valve. Everything works like normal, but my question is--Did I just doom my pump to an early death? My manual says it could damage the seals, causing leaking and flooding. Any thoughts would be appreciated.
