So, our new to us pool came with a A.D. Smith Centurian 2.2hp pump and a Pentair FNS DE filter (48sf). Apparently this is a bad combo as the pump is way too powerful for this filter. My pool is about 12k-15k gallons. Two pool guys told me that I either need to upgrade the filter or get a smaller pump. Both are fairly new. One pool guy told me that the manifold is cracked, he showed a black part (to where grids attach) inside the filter with a good size crack/whole in it.
I assume one of the grids is now cracked, I added DE via skimmer and some of it came out via return lines.
A good pump is almost the same price as a filter. I assume that I have the cheapest pump money can buy and should not expect much efficiency out of it. Would love to get an energy efficient pump to keep the cost down. Some people claim a $40 per month difference in electric bill with the new Pentair IntellFlow pumps.
Open to suggestions.
FYI - summary of my week:
1. cooktop's glass seal breaks along the perimeter of the glass
2. Dishwasher dies
3. Pool's timer dies
Thanks God previous owners purchased a home insurance.
