how to decide on size of replacement of filter and pump for inground pool?




Pebbles


I have a standard 18X36 pool with a De filter and a 1HP motor/pump with a SF of 1.5, and want to replace my DE filter with a sand and my current pump also. I have had nothing but problems with my DE filter pressure and I want to lower my maintenance, I am sure it is due to my staying on top of it but neighbors have sand and they do not have these problems plus I have automatic pool cover so that unless open the pool usually insnt that dirty. I have gotten several quotes and each with different models, I would like to know what model you all would recommend that I narrow my choices to so that I can make this decision with better information. I just want to make sure that I am getting the correct size and series and brand that will be the best for our pool, and getting the best bang for our buck. Thank you, I appreciate your help and support on this.


Answer
Too bad you had problems with DE usually a good choice, I recommend Cartridge Filters but for your pool I would recommend a 520sqft cart filter. Check out Pentair at pentairpool.com for the clean and clear plus. They also have a large DE called the FNS which is a cartridge filter you put DE in making it a snap to remove the cores for cleaning and not having to go through the exercise of putting a leaf type DE filter back.

If you want sand Pentair does that too. Check the Triton.

For a pump I would stay with nothing larger than what you have since shure it will circulate the water faster but at a greater cost. Pentair makes a variable speed pump 4 or more speeds in two models but since you dont have a spa you would not likely be interested though the Intelliflow has an interesting feature, it is the only pump on the market that will save it self or someones life due to suction blockage. It montiors flow and senses blockage and shuts off immediately, wheather it be a full leaf basket or a living blockage.

How long should I run my pump?

I have a 20' X 40' in-ground pool with a 4' shallow end and a 12' deep end.
How long each day should I run my pool pump?
I use powdered chlorine.



Answer
I run mine about 12 hrs per day, for a similar sized pool and 2 HP Challenger pump. That amount of time is sufficient to keep the pool sanitary, well mixed (no hot or cold spots), and for the skimmers to catch most of the floating leaves etc.

I run my Polaris (automatic cleaner) about 4 hours per day as well. It gets the crud that falls to the bottom of the pool.

While it's true that pool pumps are designed to run continuously, running them more than necessary chews up a lot of electrical power (a 2HP pump costs about $5/day or $150/month to run continuously; cut the run time to 12 hours per day and you save $75/month) and reduces the ultimate life of the pump and especially its motor (motor replacement for a 2 HP/240V can be $300 or more).
