What is phosfree?

Phosfree is said to remove phosphates from pool water which is then cleaned out with the regular filter clean or backwash. reducing phosphates in water reduces the posibility of algae in pools.

How do you increase water pressure on a swimming pool filter where water is going in the filter?

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.

Why is there no pressure in your pool?

It is not possible to have pressure in a pool

Where will you experience greater pressure swimming in the sea or in the pool at the same depth?

Salt water is more dense than fresh water. The added density adds pressure, so the pressure will be greater at the same depth in salt water. This is also the cause of the increase of buoyancy in saltwater.

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.

Does the temperature of water increase the deeper you go in a pool?

No, it gets colder and more pressure the deeper you go in a pool. because cold water sinks to the bottom

Why does pool water pH keep rising unless acid is added?

The source of your water that you add into the pool will increase the PH level. Also the chemicals you might be using will also do the same thing. Any chemical that may have Sodium in it will increase the level.

What is the PSI for a inground swimming pool?

depends on size of pool. the bigger the pool, the more area that is covered by water. by adding more water you increase the pressure that will be administered to your swimming pool. make sense? doesn't to me, but its the truth. Swimming pools do not have PSI per say.

You added chlorine stablizer into the pool and now it is showing no chlorine?

Have you actually added liquid chlorine to the pool?

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.
