Is this pressure of water going in a filter or pressure of water coming out a filter? Do you mean increase the flow of water? An increase in the filter pressure alone without going to a larger size impeller or newer pump will only indicate that the filter is getting dirty. If you need more flow consider changing the impeller or even upgrading the pump BUT you have to know what the outcome of that change will be. You have to know what the hydraulics and pump curve is in order to keep from overpumping the water. Too much flow can be detremental to the Plumbing, the pump, the heater. Going to a large size pump most likely now increase your flow if the pipes can not handle that extra flow of water. Sometimes whrn a pump is not sized properly - going to a smaller size pump or impeller - whichever the case may be - will increase the flow of water or GPM. There is a is a trick or formula for sizing pool pumps, filters and heaters to a particular pool.

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.

Just let your filter get dirty and the pressure will increase. To increase the flow rate from the norm a bigger pump will be required.

if the psi is too low then you might have a clog in your intake line or an air leak in the pipes; or you may possibly have a very large filter that runs at a lower psi than normal.

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.

first you have to take the water hose; then you turn it on blast. But if you have a nozzle on it you can switch it.

The pressure increasing indicates that something is blocking the filter.

Can you put chemicals in the pool while the vacuum is in?

You should not put chemicals in the pool while the vacuum is in. Put the chemicals in and give them a chance to work first. Then you can vacuum and backwash the filter as needed.


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.

Add the aluminum sulphate to the pool. Run the filter for two hours. Wait overnight to vacuum the bottom of the pool.


How does the pool vacuum work?

The same as the floor vacuum inside the house but instead of it sucking air it sucks water through the filter. Just run the pool hose from the pool vacuum to the vacuum plate over the top of the leaf basket. then turn on the pump and runi t along the floor of the pool.


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.


How often should I clean my pool?

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.
