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.

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.
How do you backwash a regular pool not a de or sand?
Backwashing is done to clean the filter media in sand and DE systems. Cartridge filter systems don't have a "backwash" provision. You just remove the cartridges and wash off the dirt and debris with a hose.
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
Where is the backwash knob located on the swimming pool pump?
The "backwash knob" - usually called the handle - is located on top of the filter or just to the side of the filter on a sand filter. They could be on the very bottom of the filter or to one side of the filter but never on the pump. The filter is the large tank.
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.
When sand filter set on filter water leaks out backwash hose?
It sounds like either your valve is not set completely to "filter" or your valve's seals are degrading. If the valve is completely set to "filter", then either replace the valve, or plug the end of the backwash hose.Here's a good place to look for new backwash filters: http://www.swiftpoolsupplies.com/category/product-list/backwash-valves
Your swimming pool in filter position but is still aloowing water to backwash from pool?
You may have to check the seals in the multyport on top of the sand filter.
Why sand filter is batter than cartridge filter?
Less maintainance with sand you just backwash, and change sand every four years. Cartridge filters clog and have to be taken out and cleaned often. Use sand it is hands down a better system.
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.
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.
You had the sand changed and sand comes out when you backwash even took the output cap off and sand poured out until you replugged it?
It sounds as if there is too much sand in the filter , try reducing the sand level a little
