My pool pump and DE filter have run for over 13 years basically trouble free. But this Spring, when servicing the filter, the flex tubes are worn out and in need of replacement. I put it back together and ran the system, and the filter wasn't operating correctly so I tore it open again, and it seemed to be OK.
The pool pump has been running hot which may or may not be normal, but the slight rattle noise and overall noise might not be 100%.
So I had everything replaced a few days ago $3,100 new variable speed pump with built in timer, and the newest model DE filter. I thought about installing it myself, but an extra $300 for installation seemed like a bargain to me. The install was complicated (to me) because I needed to bypass the old timer when hooking up the new system. So the install tech bypassed the old timer and somehow figured out the wiring buttoned everything up, then tested the system which I thought was pretty amazing. He was pretty confident in his rewiring, and it worked pefectly.
This variable speed pump runs for two hours at a high speed then runs six hours at a greatly reduced speed, then finishes off at high speed for two hours. All of these settings are adjustable. But will it hold up for 13 years trouble free years? I wouldn't bet on it lol.
