Filter is being bypassed at backwash valve, due to poor spider gasket in valve, or there is a broken lateral in bottom of sand filter, causing debris to return to pool..

At what pressure should you backwash a sand filter


The back pressure at which it's time to backwash a sand filter is about 6-8 psi above the baseline pressure of a clean filter. Just after following the procedure to backwash and rinse your filter, check the sand filter's back pressure at the time you return the pump and filter system back into filter mode. This is the baseline pressure of your clean filter. As the filter gathers particulates from the pool water, the back pressure will rise over time, as indicated on your pressure gauge. Once the pressure reaches 6-8 psi above the baseline, it's time to backwash.

Some advice: Don't assume the baseline pressure will remain the same for your sand filter. The baseline pressure will change over time and when the sand media is replaced. Typicallly baseline pressure will go up slightly over a season due to captured particles that are difficult to backwash out. Use of a filter cleaner will help remove these captured particles.

More advice: Even with the use of filter cleaners and proper backwashing, sand media will not last forever. The constant water flow and movement of particles in the sand over time shears the surface of each little sand grain. Like a river flowing over rocks, over time each sand grain surface is smoothed, and thus its effectiveness for capturing small particles is reduced with ongoing use. A typical rule of thumb is to replace the sand media +/- 5 years. Some pool owners do it more often, some less. It depends on how long your pool season is each year and how much debris the filter much extract from the pool water.

Why does the filter basket never seem to catch anything and it never reads to need to be backwashed...but the water is still not clear....what are we doing wrong?


Because of the size of the filter - 18", I would presume this is an above ground pool?

  • Do you have a skimmer?
    • If so, put some leaves, larger organic debris, etc. into the skimmer. They should end up in the basket of the Hair & Lint Pot!
    • That would prove your question to be either working or not.
  • If you don't have a skimmer, then you have a suction port in your pool.
    • Let that suction port suck some larger debris that would stay in the basket. Again, you will prove or disprove, whether debris is getting to your pump basket (Hair & Lint Pot Basket).
How long has your pump & filter been operating?
How long do you let your pump & filter run per day?
  • It should run at least 8 hrs per day.
  • If cloudy, you should run continuously until clear.
How long has your water been turbid/cloudy?
  • Use a clarifier, Natural preferred, like SeaKlear, daily at recommended dosage, until clear
What is the pressure?
Are you saying that it is the same pressure as Day 1, has not climbed at all?
What do you mean: Does not read that backwash is needed?
What in your understanding is: "Time to backwash the filter"?

You should know the "Starting Pressure" of your Sand Filter!
  • When sand is absolutely clean & free of any grime and sticky residue.
    • Just added media, when just installed is the best time to make a note of the starting pressure on a working pressure gauge.
  • When the pressure rises 8-10 lbs. over starting, time to backwash!

While vacuming loses suction, sand filter pressure goes high


That increase is due to the filter loading up with debris. Is the pool unusually dirty? If there is a lot of dirt and silt in the pool use the "waste" setting on your backwash valve while vacuuming.
This allows the water to bypass the filter and go directly out the waste line. Keep an eye on your water level because you will be removing water from the pool and may have to add more.

I have a hayward s200 sand filter and there is no pressure build-up to indicate a backwash is needed why


Do you have a strong flow of water back to pool? If so, perhaps pressure gauge is defective, pool water is relatively clean or particles are too fine to be captured except through multiple turnovers.

How to use backwash to waste


When the filter get clogged the pressure in the filter increases and there is less water flow returning to the pool.
If your filter is a sand filter, when you turn the valve to backwash and turn on the pump it reverses the water flow in the sand filter to flush the dirt out of the filter to waste. Look at the window openning in the waste pipe and keep the backwashing goinging until you see clear water.
Then turn off the pump and move the control valve to Rinse, turn on the pump for a few minutes, this returns the water flow back to normal but the water goes to waste to make sure the sand filter is clean.
Turn off the pump and move the control valve to filter and turn on the pump. This mode is the normal operating mode and the pressure gauge in the sand filter will show a drop in pressure.
Some pressure gauge shows a red section to indicate when backwashing should be carried out.

Have a Hayward side mount pro series sand filter. Just recently the top lid has been popping off . Clamp appears to be in good shape. getting a pressure build up. Any thoughts on the cause/


A pressure build up, indicates several possibilities: 1. An obstruction or closed valve after the filter. 2. A clogged filter. If your filter is equipped with a multiport valve, try the valve setting in the backwash or bypass settings and see if the pressure changes. in the bypass setting, if the pressure remains, you have an obstruction or closed valve after the filter. if the backwash setting causes the pressure to drop, you either have a seriously clogged filter or an obstruction or closed valve after the filter. Assuming the sand is less than 2 years in place, have you checked the sand condition by digging down into the sand deep and checking to see how much debris is still in it? Sand filters DO NOT backwash everything out and will build up over time, requiring a complete dump, clean and refill with fresh filtration sand. If you take the time 1 or twice a season to manually stir up the sand and then backwash repeatedly after stirring it up, you can keep the sand in place for several more years of service. If you live in an area with hard water, it is not unusual to see the sand turn hard like concrete and have to be replced after only a couple years of use. This is typical when pool water pH is high and proper maintenance of the chemistry is neglected. As to the lid popping off, this means the pressure is excessive or the clamp is damaged.

Another point to consider if the condition of the pressure gage... is the reading accurate? In most cases the reading should never be higher than 20, ideally, down around 10-15PSI on clean. Any reading higher, indicates a dirty filter or obstruction after the filter.

Low water pressure coming out after pump is on


Check skimmers, pump strainer basket and filter pressure. If filter pressure builds. time to backwash the filter. Also, the impellar on the pump might have debris in it...

Hayward sand filter not filtering small particles


You probably have too big of pump. It is pushing the finer stuff right back into pool. Try adding a clarifier. Don't backwash either until the pressure goes up.
