Pump and filter sizing

[wsommariva]

BTW I have a heat pump also if that matters.

the heat pump doesn't affect your pump, much- might slightly lower your water flow, which is probably a good thing in your case.
The pump and filter matchup is the concern- if you overdrive the filter, it won't work as well and you could get to much pressure and damage the filter if it gets to extreme.

Thank you. I'm considering buying a new filter. 48 sq ft DE. I have a Pentair 36 now, upgrade to a Pentair 48. I've always had cloudyness problems.

Is this a sound decision?

[wsommariva]

Alternatively, maybe buy a 1 hp pump instead of a new filter? Pumps are cheaper and perhaps more likely to fail being the reasons.

Is 36 sq ft of DE (my current filter) adequate for a 10,000 gal in ground?

i can't advise you on the DE filter but I will tell you that for a 10K pool, you don't need a 1 hp pump. I have approx. 13K and I have a 1/2 hp full-rated inground pump on my AG pool and a 200 lb. sand filter and that pump is plenty big for my pool.

I'm checking with Pentair to see if they think my filtering capabilities are significantly decreased with my 1.5 pump. If so I will replace.

Thanks again everyone for your assistance.

But, just remember, Pentair is in the business to sell pumps and make lots of money. Bigger pumps equal more money in their pocket. I'm just sayin ..................

bigger filter means less cleaning- 36 is probably enough for 10k gallons, but 48 would give you an extra 1/3 time between clean/refill, pretty much...
even with the bigger filter, I'd down size the pump- and consider a 2 speed run on low for filtering, only high for water fountains/etc and vacuuming-
on low, consumes like 1/4 power but 1/2 water flow, so on low 2 hours filters as well (sometimes even better) than high for 1 hour, but less total power used to get it there!
