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

Answer 1

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.

Answer 2

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.

Answer 3

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.

Answer 4

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.

Answer 5

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.

Answer 6

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.
