Question about Hayward Pro Series 18" Above Ground Pool Sand Filter System with Pump

3 Answers

Pressure up past 15 or 20 shortly after

I am running the start up chemicals and the filter has been running for long periods. I backwash when needed but after 3 days the pressure has started to build over 15 after an hour of run time. the water is not green just cloudy. checked all skimmer baskets they are clear. Changed the sand weeks ago. can't find a reason for the high pressure and lack of suction.

When pool is cloudy/turbid, and filter is working properly...
that contaminant ends up somewhere! In your filter, and if the filter clogs up - pressure climbs, at a rate of within an hour as you stated; That Is Awesome! Backwash and keep doing that until clear, maintaining a chlorine level on the higher side, 3.0 ppm!
Add clarifier daily, to assist in clearing.
But the important thing here would be to know... After a good 2-3 minute backwash, do you get full suction again?
If so, you are Golden! If not check impeller, it may be clogged internally.

Sounds like it needs a good 1minute back wash do you have a rinse on your multiport backwash stop rinse stop do 3 cycles of that think though everytime you go to each mode turn off pump backwash off turn to rinse back on again stop pump almost like switch gears driving a stick

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.

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!

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.

Who often should I backwash sandfilter


I would let it run for about a minute depending on how clogged it was. Our backwash drain is very visible so we can see when the dirty water has left the filter, usually about a minute or two.

Backwash the filter. If the water coming out of the backwash line is not dirty you need a sand change. If the water is dirty you need to continue let the water filter and back washing once a week. Also make sure the six way is on filter and not recirculate

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

Recommend backflush pressure of a hayward pool filter


After you have backwashed your filter until the site glass run clear. Go to rinse mode for 30 seconds. Make note of the filter pressure. Don't backwash until the pressure goes up 10 psi!! It is important not to backwash too much. As pressure climbs the sand filter actually filters better.
