If you're talking about the pressure on the filter tank, 8-10 PSI is a good and normal range. You don't want to increase the pressure in this tank. In a perfect world, it would stay in the 8-10 PSI range.

But, it will not stay at 10 PSI because the more stuff is removed from the water the more clogged the filter gets and the higher the pressure goes -- when it gets to 15-20 PSI it's time to backwash and recharge the filter.


"if it has to much sand would that cause that problem"

If you reduce or remove the sand from the filter the pressure will go even lower. You have no problem I see.. I could be missing something...

Tip

Backwashing A Sand Filter with A Push/Pull Slide Valve or Multiport Valve


Lots of people are first time pool owners and pool professionals forget to teach these "newbies" about the simplest aspects of pool ownership.

One of the biggest questions we receive from new homeowners is "How do I go about backwashing my sand filter exactly?"

It doesn't matter if you have a Hayward, Pentair, Jandy, Sta-Rite or any other number of Sand Filters on the market they all utilize the same basic valves for backwashing; a push/pull slide valve or a multiport valve.


To backwash with a multiport valve:
1) Shut off pump motor.
2) Press down on valve handle, rotate valve from FILTER to BACKWASH position.
3) Roll out any backwash hose or open any waste line valves.
4) Open air bleeder assembly on filter, and turn pump on.
5) Watch pressure gauge for backpressure and hose for kinks. Be prepared to shut off pump quickly.
6) After hose fills with water, run for 3 - 5 minutes or until water runs clear.
7) Shut off pump motor and move multiport valve handle to RINSE position. Run on rinse for 15 - 25 seconds.
8) Shut off pump motor and move multiport valve handle to FILTER position.
9) Turn pump back on and note lower pressure.
10) Roll up backwash hose so the dogs use it as a chew toy.


To Backwash a sand filter with a slide valve:
1) Shut off pump motor, roll out backwash hose.
2) Twist to unlock plunger T-handle, push or pull(depending on manufaturer) the plunger 2" - 3".
3) Open air bleeder assembly on filter, and turn pump on.
4) Watch pressure gauge for backpressure and hose for kinks. Be prepared to shut off pump quickly.
5) After hose fills with water, run for 3 - 5 minutes or until water runs clear.
6) Shut off pump motor and push T-handle back down into locked position.
7) Turn pump back on and note lower pressure.
8) Roll up backwash hose.

Now you are a backwash Guru!

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.

Pump is blowing cloudy water back into pool


Cloudy water is the bane of sand filters!. I suggest letting filter run day and night. Do not backwash until the pressure rises 8 - 10 pounds above clean starting pressure. Do not try to vacuum or stir up the sediment. when water clears, vacuum to waste. Keep the hose running while vacuuming. A dirty filter is a better filter (up to a point). At a higher pressure the filter will trap more of the fine particles that are clouding your water.

Pressure guage is reading high upon opening this spring. does not help with back washing/rinse


Is the Pressure Guage operational? Does it go to 0, when you turn it off?

If not, then replace gauge. if it does, then your sand is clogged. Use a sand filter cleaner. Add this into the tank, then it sits & soaks for at least 12 hours or so. Use one of good quality and follow label instructions.

Pool had a lot of brown silt algae,cloudy put in correct amount of chemicals,back washed several times.pressure at 17 lbs goes to 21 in 1 hour.Tried to drain filter and I cant get the water to come out.I...


First I'm assuming we're talking about a sand filter. Back washing is the right thing if pressure increases.A 8-10psi pressure increase is the magic number where you must backwash. Be sure to run a rinse cycle too before returning to filter. If you want to clean filter you can buy chemicals that you add to your skimmer as you backwash. Follow their directions. If you do want to drain the water, open your basket cover on the pump and remove plug, this will allow air to enter the filter, so it will drain. It drains slowly. Not really necessary, except to winterize.l
