Your pump and filter are rated at a certain psi. To change that you would have to change the pump and maybe the filter.
That depends on filter, pump and plumbing size. What else is plumbed into the system. Does it have a pool cleaner attached and how? All this is called or is referred to as the amount of head. Ken
Around 10 PSI if you have a 2 horsepower pump. It will vary, depending on the restrictions in the exit line. Pool Masters
The cleaning schedules varies from filter to filter, but a general guideline on any swimming pool filter is to take a reading when the filter is clean, then clean the pool filter when the pressure rises about 10 psi.
Could be a number of reasons: Your pressure gauge could be wrong, your filter may be partially clogged, your pump may be to big (to may HP) for your pool. In your instruction manual for your filter, it should tell you what the maximum PSI for your filter is. The pump manual should also tell you what the operating PSI is. Check them both to make sure that you're not damaging one or the other. Also, check to make sure that your pump doesn't have a low and high setting (or "turbo" setting). Some older pumps have these options. If your pump has one, set it to low and that should drop your pressure some.
If you remove the cartridge from your filter housing, the presssure reading will drop. If you are having low pressure issues this is an easy way to determine if the problem is on the pressure side of the suction side of the pump. Depending on what type of pool you have, and what in on the equipment pad. If you pump usually runs at 15 -18 psi then with out the filter I would guess it would be about 8 psi. Hope that helps.
If you have 36 ft. x 16 ft. pool I would run the filter and pump 24 hr a day and backwash when ever you have a 7-10 psi raise on filter pressure gauge. All commercial pools run 24 hr per day. If you want sparkling clear pool I recommend that you do the same. john www.unblockabledraincovers.com
The psi on your pool pump indicates how much dirt there is in the filter, the cleaner the filter the lower the psi. normally when the filter is clean you wil have a low psi and as the filter gets dirtier it will rise. However if the psi suddenly becomes much lower then usual it may indicate a fault in the filtration is letting unfiltered water circulate back into the pool as in a torn filter cartridge.
The best way to determine this is to backwash the filter and see what the pressure is at that time. Then go 7-10 PSI above that and this will be your pressure to watch to tell you when to clean your filter.

What is a normal operating pressure for a jacuzzi sand filter for an above ground pool?"
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.
