I would need to know alot more info than just the hp. Different brand pumps have different pump curves. For example a Pentair Whisperflo 1/2 hp pumps more water than a 1hp jandy pump…ect.. You will need to research what you need your turnover rate to be for your size pool. Then you need to determine how many gpm your pump moves and then you can determine which size filter you need. If you read my previous post on 10/12 explaining a bit about about TDH and flow rate it may help you out a bit.

I have a 16 x 32 ft inground pool. My pump is 1.5 hp. I was told that a Hayward 24 inch sand filter will work, but then I was also told, by someone else, that my pump is too big for that size filter. I don’t know what to believe, can you help me out?
Thanks!

Thanks, I went with the Hayward Northstar 2.0 hp per flow rate need. I appreciate your response, thankfully it confirms my decision.

With a 24,000 gallon pool you you need an 8 hour turnover rate. In order for you to do that you need a pump with a 50 gpm flow rate. The length of your pipe does not matter so much as the size of your pipe. 1.5 inch pvc will only allow 42 gpm to flow, so even if you have a pump that can move double that it will do you very little good. Im assuming since you have 2″ returns that you have all 2″ plumbing. 2″ pvc allows 73 gpm. We will also ASSUME your pool has a TDH of 50-60. So all you need to do is to look at the pumps maximum flow rate to determine what hp you will need. Different brands have different pump curves so you cannot rely on hp alone. When you decide what brand you want to go with look at a comparison chart to see which hp you will need per that brand pump. Choosing the correct pump for your pool will save you money on electricity and wear on all your other equipment.

Help? I have been researching a new pump. I have a 24,000 gallon pool,buil in spa-fountain, 4 total 2 inch returns, a heater and a cleaner with booster and a 72 Sta-rite DE filter. Longest pipe run is 106ft, shortest 55ft and the others 70ft, replacing a 2hp Sta-rite….factor 1.1……I almost pulled trigger on SP4020 Hayward Northstar- full rated 2hp X 1.20= 2.4, but I found a SP4015 Northstar - max rated 1.50hp x 1.60= 2.4..are these motors the same thing? What will be the actual difference for me? thanks, Jeff Seger Texas

Most likely you need to change your impellar. The rule is when you go to a bigger hp motor you always have to put a bigger impellar on. Otherwise it will do exactly what your describing. It running hot, tripping the thermal switch and shutting down. Then when it cools it will start over. 9 out of 10 times you dont have to change the impellar when downsizing motors, but this isnt always the case. You need to research what size impellar fits your pump for that hp and sf motor.

Have a 30,000 gallon in ground pool. My motor burnt out and was just replaced. The connector was burnt. It was only 5 years old. It was a 1.5hp and the new one is 1.0hp. The pump was not changed in the process. The new motor gets pretty hot and shuts off and after a few minutes goes back on. Is this an electrical issue as I had the hurricane and it impacted the power in our area. The pool circuit breakers are not tripping. Everything in my home still works fine.

Sandra, I would reccomend a 24″ sand filter. We have many options to choose from on our site. http://www.royalswimmingpools.com/ING-pumpfilter.htm

Hi Scott, I have what may be often described as a Garden Pool. 18′ round 4′ deep fiberglass in-ground 2 inlets, one skimmer in pool plus inlet to a very large waterfall. I had a Sta=rite 3/4 hp pump w/ 18″ sand filter. The water fall 3′-3-1/2′ above water level hooked to filter. NOT a very good flow but still kept pool realitively clean. I was told to get 1 1/2 hp to accomidate the water fall flow which I did looks great! but too big for the filter, 30+psi ! water is cloudy what size filter should I get?
