because the leak releases pressure?

when the pressure is high on filter mode it usually means that a backwash is required.

A pool with a sand filter or for that mater any filter is set up to push water through the fitter to be filtered. when the filter is clean the gauge in front of the filter Will have a low pressure reading. As the filter gets loaded with more of the dust and dirt that comes from the pools water it becomes harder for the water to pass through the filter and the pressure on the gauge goes up when the pressure get high on the gauge it is time to backwash the sand filter or to clean the cartridge filter. When the pressure on the gauge is high the suction from the pool is low. When the suction from the pool is low even when the pressure on the gauge is low there may be a problem with the pump, or a blockage between the pump and the pool, To increase the amount of pressure on a clean filter the only thing that can be done is to enlarge the pump.

When the pressure in front of the filter get high or the suction to the filter is to low its time to backwash.

No you only backwash your pool when your filter pressure on your filter is high 30psi and above on most pools. If you backwash your pool be sure to add two scoops of de to your skimmer. If the presure is still high the u need to clean the filter

Specifically where is it leaking? At the gasket? Replace gasket.

The pressure gauge that is set up in front of the pool filter is there to show you when the filter needs cleaning or back washing. when the pressure gets high it indicates that there is too much dirt there for the water to pass efficiently, Cleaning it at this point will reduce the pressure and make the water flow better through the filter

Let me say first backwashing is a process for simply ridding the filter of dirt, once you backwash the pressure and cleanness of the filter will begin to collect and store more dirt from the pool, Look at the gauge at the filter remember the pressure or write it down as the pressure goes up the flow of water going back to the pool will go down to the point that very little water will go back into the pool. When the pressure is low the water flow from the filter will be high meaning that the filter is not clogged or dirty.

Back wash valve when the pressure before the filter becomes to high usually indicated in red on the gauge the filter needs to be back washed.

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

Usually the pressure gauge on your pool equipment indicates how much pressure there is before the filter. as the pressure goes up it indicates that the filter is getting blocked and needs a backwash or cleaning. while the pressure is low the filter does not need cleaning.

Clogged Skimmer, Strainer or filter cart's. Check pressure meter...the lower the better. High Back pressure indicates a need to clean filter. Try a back wash and filter cleaning.

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.

1) a restriction in one of your hoses 2) the filter is clogged 3) the guage is not accurate

Backwash the filter when the pressure increases 10 psi above the pressure when it was clean

Clean the filter, enlarge the filter, enlarge the pipes coming from and or to the filter, enlarge the pool pump, If you have a cartrige filter put another one in paralel next to it.

No absolutely not unless you want to waste a lot of water you backwash a pool when the pressure in front of the filter becomes too high or goes into the red.

A clogged filter? The pressure AT THE GAUGE will drop after the pool is backwashed and also during vacumning. As the filter becomes clogged the pressure AT THE GAUGE will increase. The opposite effect occurs at the inlet eyeball.

The lower the better some run around 9 psi with new filter media, as the filter media gets old the filter has to work harder so the pressure will go up in the filter, so what you need to do to see if you filter is running ok, is to simply take your hand and place it in front of a inlet in the pool if it pushes your hand away you have good pressure take a reading at the filter and see what you have. If it does not push you hand away you will have high pressure at the filter and filter media may need changing or the filter may need backwashing, we have people who refuse to put a new pressure gauge on their filters they say they cost too much, and that's how they check their pressure.

Your filter needs too be purged, after you purge it your pressure will go back up,

I suppose. Was that the pressure when the filter was new of very clean? No 2 filters will be exactly the same.

I think when it happens when the pool starts to turn green

As the filter gets clogged it restricts the flow of water and the pressure in the return line drops. The pressure gauge on the filter itself indicates the entry pressure and that will go higher as the filter becomes clogged. Don't ever allow the pressure to reach 40 PSI. Back-washing the filter should restore the pressures. Pool Masters

You can not measure the pressure in a swimming pool. If you mean the pressure on the filter tank gage then you may have to backwash the filter. Talk to your local pool store for instructions as how to maintain a swimming pool and the equipment. Get some education on swimming pool maint. before you get into some real trouble. A pool is not too forgiving for someone without a basic knowledge of pools.

It is not possible to have a pressure level on your swimming pool! However the pressure on the filter gage could run anywhere from 5# to 35#

High filter pressure is cause by one thing. (resistence to flow) This can be as simple as a dirty filter. Clean filter or backwash, You may need a new filter element, or new sand and to clean a de grid. The other reason would be poorly plumbed piping (to small hydrolics)
