When you back wash
(if you you have a salt water pool turn of chlorinator while you are doing this)
(1) stop the motor
(2) reposition the lever at the top of the sand filter to the backwash position
(3)turn on the pump
(4) Normally you will see a clear plastic bubble sticking out of the side of the multi port, when its on back wash you will note the water in it turn dirty (cloudy) run until it clears and then stop the motor.
(5) now turn the lever to the rinse position you will note some cloudiness in the bubble usually I run it for about 30 seconds.
(6) reposition the lever to filter and don't forget to turn on your chlorinator.

Why is my Pool sand filter pressure to high on filter mode?
when the pressure is high on filter mode it usually means that a backwash is required.
Should you keep the backwash open while vacuuming?
No, backwashing is used during the cleaning of the sand, when the pressure has gone up on the filter, or you feel the vacuum is not doing its job that is when you should backwash.
How do you know when you need new sand in a Hayward filter for an inground pool?
Depending on the size of the pool and the size of the filter and the amount of times you have to backwash, also if you have had a lot of rain then you may need to backwash more than usual. If you put the pool in and the filter and you know how old the sand is, if you are backwashing more than usual,change the sand. Also before you backwash check the pressure of the water going back into the pool, then backwash check the pressure again the pressure should for any size hayward pump push your hand away if it does not then change your sand.
How often should you backwash a sand filter on a above ground pool?
Sand filters usually have a pressure gauge in front of them indicating the back pressure before the filter.When the filter needs to be cleaned this pressure gets high. usually it has a red section on the gauge. When it hits the red it is time to think about back washing. If the gauge does not work as so often happens with these things. you can usually judge it from the lack of suction coming from the filter. After backwash you will note the pressure will be down and the suction will be up.
Why is the pool pressure gauge so high?
Depending on the type of filter it needs to be cleaned or backwashed. Cartridge filter: Hose off. If pressure does not go down buy new cartridges Sand filter: Backwash, if pressure does not go down replace sand DE filter: Backwash, if pressure does not go down remove element from tank and hose off and or acid wash. Also... always make sure you gauge is working
What is the proper psi for a sand filter pool pump?
Depends upon your starting pressure and pump type. Generally however you want to keep your max pressure at about 8-10 psi above your first time running the filter or your most recent sand change, if it goes above this run a backwash and a rinse cycle if it still persists at a higher pressure it's time to replace your sand.
I accidentally vacuumed dirt in my pool using backwash mode instead of waste mode. How do I get the dirt out from under the sand?
There wont be any dirt under the sand. When you vacuum your pool you should do it on filter mode Otherwise you will lose a lot of water for nothing, this would be especially wasteful in the case of a salt water pool. Ofter having vacuumed the pool on filter mode and if the pressure gets too high backwash. after backwash rinse for a minute, then return to filter.
Why do you not have any pressure coming out when your sand filter pump is in filter mode?
Probably because it is clean, leave it on the filter setting for a while and you will find that the pressure will increase as the filter gets dirtier, when it get high (usually in the red ) you will have to backwash.
What are the 6 position on your hayward sand filter?
Filter, winter, closed, backwash, rinse, waste
What is an indication that a sand filter needs to be backwash?
The pressure gauge will generally read 10 PSI higher than when the filter was clean. In any case do not let the filter gauge go above 40PSI.
What to do if the sand filter gauge reads zero and won't backwash?
this usually means that the multiport valve in the filter head is bad.. the gauge is not always accurate. replace gauge. the impeller in the pump can also be cloged not allowing you to get any pressure in your gauge. the backwash will be very slow if not any..
With above ground sand pool filters when you need to vacuum should the pump be on filter position or vacuum to waste?
It should be on filter and don't forget to backwash at least once a week.
