In 2004, I inherited an above ground pool from a real estate transaction. The people moving into a house didn't want the pool and told me I could have it if I removed it. So I did.
Anyway, I don't know the history of the pool or how old it is. It's been working since I got it and set it up with the the pump that came with it and the sand filter. The plate that has the motor rating was scratched up pretty good right where the hp entry is so I can't tell what it is. The sand filter, I believe to be an Pentair Sand Dollar 60. The pool is 18x33 oval by 48" deep. I've calculated this to be around 15k gal. This past weekend, the motor froze up.
I'm trying to figure out what's a good route to go with a replacement pump. I've heard a lot about how much you save energy wise on a 2 speed pump. Are they that much more expensive initially? With the BBB method, is it better to circulate 24/7? Also, would this be a good time to replace the filter as well or even switch to a different type of filter? Are DE filters hard to maintain? The only issues I've had with sand is that previously with my Chlorease SWG (I've quit using this now) I'd have algae blooms and it was a pain in the neck to keep vacuuming to waste and then replacing the water and getting the chemistry back in line. The other issue is that even though I replaced the gauge, the filter only fluctuates between 9psi (freshly backwashed) to 16 psi (no pressure at the outlets).
Here's some more info about the pool.
Intake from skimmer to basket - 1.5"
Pump to filter - 2"
Filter to jets - 2" that feeds a 1.5" 4ft run and a 1.25" 30ft run.
Both 120 and 240 lines run to the pump area
Both pump and filter are underneath decking with sitting ground level with the pool.
Thanks for any help and advice.
