Cleaning the filter will lower the back presure. or else a hole in a cartridge filter will also do it.

How do you lower swim pool filter pressure?

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)


When cleaning the pool I don't have much suction?

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.


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.

What is the normal gauge pressure for a 16' x 30' ingroung pool?

It could be as low as 8, or 10, 12, the pressure could even be lower depending on your filter size, the lower the pressure the cleaner your filter media is the higher the pressure say 17, then you need to back wash or change the media, if you are not using sand.


You have only about half pressure on your pool pump?

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.


Why is pool filter is leaking but the pressure is not too high?

because the leak releases pressure?


How do you increase pressure for a pool vacuum with a sand filter?

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.


What is normal pump pressure range?

The lower the pressure the less work the filter is doing, 7 to 10 psi is a good pressure. Another tip would be to put your hand by the outlet where the water goes back into the pool if the water pushes your hand away you have good pressure also take a pressure reading at the filter, if you put your hand at the outlet and the water does not push your hand away take a pressure reading, backwash the filter, put your hand at the outlet again if it pushes it away go back to the filter look at the gauge and see what it reads now, and that would be your suggested low pressure for your filter.


How often should I clean my pool pump?

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.


What should the pressure gauge read for your swimming pool?

The pressure gage on you rswimming pool FILTER should be around 8 to 12#'s. There is no pressure gage on or in a swimming pool. The pressure gage would be on the top of your filter .. . that's the large tank with up to 2" pipes plumbed into it, located next to the heater and the pump - the small pot with a motor attached to it.


What is the proper psi for a sand filter pool pump?

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


Your pool pressure gauge is over 30 psi?

Clean the Filter!


How do you increase Water pressure going out from filter to pool?

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.


How can you tell if pressure gauge on pool filter is broken?

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


Why is the water pressure back into your above ground swimming pool low?

If I was to make a guess, I would say if you have not tried backwashing the filter, then it is time to change the filter media inside the filter.


What is wrong if there is very little pressure when you turn on the pool filter?

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


The pressure on pool filter gauge is 10 is that ok?

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


What causes pressure with a pool pump to drop?

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.


What should your pool pump pressure be?

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.


Why did the pool pump pressure increase when PhosFree was added?

The pressure increasing indicates that something is blocking the filter.


Why does the swimming pool filter have too much pressure?

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


Which valve lowers swimming pool pressure?

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.


Why does the water pressure go down with a dirty pool?

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


The pressure level on your swimming pool is only 5?

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#
