I have a 1HP Hayward superpump. Average 25 ft of head on return piping. Is a sand filter with a flow rating of 74 GPM large enough that i won't have problems with the pump being too powerful for the filter?
Hi Mike, Based on the info provided the S70T2 filter will be adequate, the Hayward Super Pump 1 HP will not be too powerful.
What are the waste and closed settings used for?
The waste position can be used to drain water from the pool while bypassing the filter. The closed position is used when/if the pool is closed for the winter.
How often do I have to replace the sand in my filter? What is normal operating pressure?
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.
When should I change the sand in my filter?
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.
