If you're using a sand filter you don't use diatomite like you do on a DE filter. You should 1. Turn pump off. 2. Move valve to backwash. 3. Allow to back-flush till water is clear (check sight glass). 4 Turn pump off again. 5 Move valve to rinse 6. Turn pump on till water is clear again.7 Turn pump off, return valve to filter. 8 Turn pump back on again. No power is added to a sand filter. There are some materials to "clean" your sand perhaps twice a year, follow the manufacturer's directions for this.

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!

Turn off the pump.Ensure a hose is connected to drainage on the waste outlet of the valve assembly. Make sure there are no kinks in the hose.Turn the valve to "backwash" (usually opposite of filter).Turn the pump on and run for 2 min.Turn off the pump and run on rinse for 15 seconds.Repeat until the glass jar on the waste line runs clear during backwash.Return to filter. (If you have a sand filter, your done. If you have a DE filter, add the correct amount of DE to your skimmer return while the pump operates. An 18X34 pool takes about 5-7lbs.)

How do i drain my inground pool with this system


Valve off your skimmer(s) so only your floor drain(s) is open and set the valve to waste. Your pump should then drain the pool out the backwash line assuming nothing leaks and the valve effactively shuts off any skimmers.

How do you backwash to lower water level with the Pinnacle pump?


The model of pump doesn't really matter,You backwash the filter by changing the position of the backwash valve (while the pump is off). If you have a D.E. filter, be sure to add fresh D.E. powder to the filter when you are back in "filter" position.

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

When I backwash or rinse my pump reservoir fills to the top when I filter I have air bubbles at pool discharge and reservoir about 3/4 full and air is evident. Do I need to start digging up my skimmer line...


When backwashing or rinsing the same water is used as in filtering.(skimmer and main drain) so I don't think skimmer damage is the issue. Check if the pool water is low at the skimmer after the backwash cycle, Also check to see if the skimmer weir gate (flapper) is stuck in the upright position. I would suggest 2 main checks. Fill the pool higher than usual, back wash, ensure the pool water level is 1/2 way up the skimmer level and try again. Also, if your lines are valved right, shut off the skimmer during the filter cycle and see what happens. Lastly, the gasket on your multi-port valve may be bad.

Check the Filters and Skimmer FIRST even though they said they backwashed and checked the system. I am not sure how you determined it is the water pressure switch? If you do have sufficent flow of water in and out of the heater, the pressure switch could need replaced or the small copper feed line from the heat exchanger to the pressure switch could be obstructed. You really need a Heater Tech that can check the pressure switch for proper functioning and any obstructions in the feeder line, Normally you will find the Skimmer and or Filters are the cause of low water pressure.

Very low pressure when I run filter and when I backwash filter


Ok... First check to make sure the skimmers are clear, the skimmer float valve is open, the valves by the pump are all open and check the pump strainer basket too. If you are able to, take the motor and seal plate off and check for debris in the impeller. Also there should be an o-ring on the diffuser (the cone shaped part that covers the impeller. Make sure it is there and not stretched or damaged.
