Hello,
First, I want to thank this forum for the excellent advice and knowledge it has to offer. My pool water is crystal clear and very well balanced by following the procedures on this forum.
However, I am currently having to back flush way to often. After back flushing my sand filter will read 13-13.5 PSI. My pump is approximately 10-12 feet away but with how the 1 1/2" pipe runs the total length would be about 16 linear feet from skimmer to pump. When the PSI gets up 14.5-15 PSI I can tell a huge difference in flow from my return. At this PSI my Hayward above ground pool heater will stop running due to my GPM falling below 20 GPM. At this point the heaters pressure switch will activate. Back flushing returns pool to normal operation and the heater will work fine.
A little info in regards to pool:
13,000 gallons above ground pool that is buried 2 feet in ground. The pool has a deep end of 6 feet. The pump is 1 hp and is approximately 1 foot below the skimmer. All piping is 1 1/2" schedule 40 PVC.
What could be causing this?
I'm thinking that my pump might not be powerful enough based off the design of my pool?
This is a Doughboy pool which they sell as a kit so I assume the 1 hp pump would be more than enough for a standard build. ( not being buried and 6 ft deep) The pool store has offered no help but to back flush for longer periods of time.... this does very little if anything.
I have no sand coming out of the return and almost always my pool water is clear coming out of my back flush pipe. The heater is a new addition this year and last year I don't recall having to back flush as frequently but still noticed a difference in flow within a couple PSI.
Any help and guidance would be great, I look forward to the responses.
Thanks
Greg
