I have several issues with our inground Pebble Tec pool. Sand filter, 13,500 gallons. 30'x 15' x 4'. The 4' is an average depth. It goes from 3' on each end to 5' in the middle.
First thing, I live in TN but the pool is in AZ. So I cannot go and do things to it. It is being maintained by a renter who is a relative, but is a complete novice to pools.
The 2 HP pump motor was replaced with a 1.5 HP motor. Don't ask why.
The several tubes connecting the pool vacuum (Hayward) to the connector on the side of the pool was replaced by a single 25' one, which is longer than it was when it was several 4' sections. I think it was 16' long then, but I cannot recall for sure.
It is very very green (opaque). They seem to be having problems keeping it clean.
The vacuum feet do move freely but it does not drive around when released. There is vacuum on the line.
Is it possible that the undersized motor is the source of the problem in that it cannot provide enough vacuum to drive the Hayward?
Is it possible that the extra long vacuum line is the source of the problem in that it reduces the amount of pull available to drive the Hayward?
If I need to put in the correct sized motor, will any 2 HP motor do, or are they different with the connections and such? If they are different, what do I need to look for to determine the correct one?
Thanks a lot for taking the time to help.
