When should I change the sand in my filter?
Reply
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.

How often do I have to replace the sand in my filter? What is normal operating pressure?
Reply
On a "fresh start-up" a filter would operate anywhere between 10-20 psi. As a general rule of thumb you only want to backwash when the pressure increases 8-10 psi. You want to make certain that the pump is being turned off whenever you move the handle on the valve. Once backwashing is complete (3-5 minutes), you can switch to the rinse option to re-settle the sand bed. Sand will typically last 5-7 years. Premature backwashing will wear down the size of the sand which will cause difficulties such as cloudy water and higher operating pressures.

I just replaced the sand in my filter. When I turned the pump on, a lot of sand shot back into the pool but there is little to no suction. What do I do?

If you are getting sand back into the pool, that would be an indication that the laterals would need to be replaced. If I am understanding correctly, you lost suction after the sand was replaced. If so, you may want to check the line between the skimmers and the pump. The skimmer closest to the pump and filter should give you the strongest suction. You can also try blocking on of the skimmers to see if this helps.

We purchased our house a couple of months ago, it came with an 11,000 gallon above ground pool with a Hayward Pro Series High rate sand filter. (s210T ). Everything was working fine up until a couple of weeks ago. Now when I vacuum the pool I can see the dirt and green algae being blown back in after a couple of minutes. I have it on the filter setting like it is supposed to be and I have backwashed and rinsed but it is still shooting everything back in the pool. Please help.

If there is too much algae or dirt in the pool then older sand may not efficiently filter these organics and such out. Its wisest to vacuum this debris directly out of the pool keepng the multiport in the waste position then using the filter to grab the rest of the impurities. Also make sure that the pool has enough water when performing this task. Lastly please be advised that sand should be changed anywhere between 5-10 years.
