What is the voltage on this unit? How long is the manufactures warranty? If the system requires repairs during warranty, what do I do?

This pump runs on 115V power. This unit comes with a 1 year manufacturer's warranty. If the pump needed repair, you would call Hayward directly and they would put you in touch with a warranty service station in your area.

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.

what pump do you recommend for a 18x33x52?

If you are looking for a pump and filter combo for an 18' x 33' above ground pool then this is the system I would suggest. If you just need a pump then I would suggest the Hayward Matrix 1.5 HP Pump
