Hi all,
We have a small 6000gal above ground pool. It came with a pump and cartridge filter but we upgraded to a 14" sand filter kit to not have to constantly wash out the cartridge.
I was going to buy a filter locally but the pool store near us did not carry something that small so I got a pump/filter combo on Amazon and bought the filter sand locally. It calls for 60lbs of sand filled between half way and 3/4 in the tank. I filled it to 3/4.
The issue that I'm having is that it does not seem to actually be filtering the water. The pump is moving plenty of water through the system. There are two inlets, one is connected to the skimmer and the other has the strainer on the side of the wall. These are T'ed together to the inlet of the pump. The pressure gauge reads 4psi.
I have verified that the valve is in the correct position. This one is simplified from the standard Hayward valves in that it only has Backwash, Rinse, Filter and Winter positions.
I've let it run for 40+ hours and it has had no change on the clarity of the water. The chemistry looks good with the correct chlorine and ph levels, yet the water is murky and unfiltered. The pressure never changes from above 4psi even when the filter has run long enough to need to be backwashed. The pressure is the same in all positions of the valve. In reading about low pressure all indications point to restricted flow but the flow is very good to and through the pump.
When backwashing, the flow is good but the water runs clear like nothing was captured in the sand. You can hear the sand moving around in the tank. Rinsing looks the same.
In an attempt to trouble shoot I removed some sand to get it to the 1/2 way mark. This made no change. I even disassembled the valve to check and see if the seals were good or if it possibly had been assembled 180 degrees out of alignment. But everything looked good and the segments of the valve in filter mode line up with sending the water from the pump to the distributor in the top of the tank and then on the standpipe outlet it is sent to the return to the pool.
Any thoughts as to why the filter is not filtering? Thanks!
