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.

For model S166T What size Pump would I need.? 1HP or would 1.5HP give me more filtration.
Reply
Hi Fred for the S166T filter I would suggest not going larger than 1 HP. If you wanted to go with a 1-1/2 HP pump then I would suggest the Hayward S180T Sand Filter.

Are the sand filters shipped with sand?

Hi Dawn, No the sand filters are not shipped with sand, normally you can find pool filter sand at your local hardware store for around $5 per 50 lb. bag.

I am trying to clear up a green pool, it started okay turned blue but cloudy. Everything was operating fine until i swept it? I did not realize i should have had it on waste to sweep and now there is no water going back into the pool? What did I do and what can I do to make it work again? Thanks!

Your filter is getting backed up with the dead algae that you have killed. You will need to remove all of the dead algae from the pool for it to clear up. One way is by backwashing multiple times a day or vacuuming the pool to waste. You can do this by placing the multiport valve into the waste position before manually vacuuming the pool which will discharge most of the dead algae that has settled on the pool floor. Keep the pool chlorinated, algae killed and filter as clean as possible until the pool has cleared.
