When should I change the sand in my filter?

A  Answered on 1/27/2012 by InyoPools Product Specialist Patrick P.

You should change the sand in your filter every 5-7 years. You can generally tell that it is time if your pool water is not as clear as it normally is or when you notice the interval between backwashes is shorter. You can use > this guide to walk you through it.

what size flter do I need for a 30,000 gallon in ground pool? will the Pentair sand dollar 60 work efficiently ?

A  Answered on 6/5/2016 by InyoPools Product Specialist Lennox H.

Hi, The efficiency of the filter all depends on the flow rate of your pump. The SD40 has a max flow rate of 40 gpm and the SD60's flow rate is 60. You will have to calculate the flow rate of your pump to determine what size filter you will need. You can use our How to Size a Pool Pump for Your In-Ground Pool guide.

I cannot remove the water and sand drain plug at the bottom of the filter tank.

Hi, Debra. You may have to use a strap wrench if the cap is on too tight.
