Low flow indicator on saltwater pool filter

I have an Intex saltwater pool filter. Have everything hooked up right. Have cleaned all of the sensors. I think I've done everything to trouble shoot the problem but still the "low flow" light comes on after about a minute of running. Could someone please give me an idea of how to fix it because the saltwater feature is not clearing the pool. Thank you. Donna

If your pool has the skimmer system there is a hose coming from the bottom of the skimmer to the wall of the pool which would be your suction to the pump. Disconnect the hose clamp from the suction port that goes through the wall of the pool remove the hose then unscrew the blue adapter on the inside of the pool there you will find a strainer / screen. Whatever gets pass the basket in the skimmer get's plugged up in that screen causing the pump to starve for water causing the LOW FLOW sensor to go off on the Saltwater pump.

Let me know if this helps any.

Lets start with the bad news first.
The intex salt system does not give you a clearer pool.
It only generates chlorine so that you do not have to ad liquid or tablets.you still need chemicals

You still need to use a stabilizer to help hold the chlorine level
what drops the chlorine level?

# of swimmers, how sunny that day, how hot that day, did anyone get in with sun tan oil, rain, and so on

This will determine how long to generate chlorine

get salt test strips that read #'s not color coded and get your pool to as close to 3000ppm as possible no lower than 2800 and no higher than 3800

you should also add a good non foaming algaecide once a week follow directions for your gallons of pool

Now to the low flow Intex is a terrible pump to begin with. It does not pump enough from the get go


open your bleeder screws and let all of the air out you can get air from vaccuming,skimming, and cleaning your filter.
once you think the air is out then turn pump on for 1 minute then close the valves
there are 2=3 depending on your model pump
Most common one is on the top of the cap that covers the cartridge

also you should clean out the cartridge at least every other day even if it doesnt look dirty it still is and run your filter at least 12 hour a day this does not include generating time

here ar generic #'s since i do not know gallons of water for your pool or pump size

A pool needs to be turned over at LEAST 3 times a day so if you have a 6000 gallon pool and a 2000gl ph pump you need to filter at least 9 hours you do the math for your set up

Also here is a link to manuals and videos but it does not really help all that I have wrote is not what works in the manual this is what has worked for me for 4 years and I have never gone green or cloudy

Do I hook up just the pool filter for 24 hours and then hook the intex salt walter filter onto the pump?


When you are opening the pool each year or for the 1st time, you hook up the filter pump and than the Salt System before you start filtering the salt... Eventhough you filter the freshly added Salt into the pool for the 1st 24hrs, it can run through the salt system, just don't turn it on like you mentioned... The trick is once you start running the salt system is to get the chlorine levels up as quick as you can... I have not mastered this yet after 3 years but I will consult my Local Pool Chemical Supplier next year before opening the pool... So I think you should do the same...

Good Luck...

Code 90 low water flow don't know why


Here are some things to check. First ensure you have bleed all the air out of lines and that there is not a blockage. Then ensure the water inlet supply hose is and the water outlet supply hose are hooked up correctly. Pretty much the pool water should be going into your filter pump first. Then your filterpump will pump into the saltwater system and back into the pool. If this is correct, check the PVC pipe with the flow sensor. Its the pipe to the right if you are looking at the machine from teh front. It also has an electrical connection coming out the top of it. Ensure that the arrow on that PVC pipe is point in ths same direction as the pipe to to its left. If all that checks out, then unsrew the electrical and pull out the flow sensor and clean it a rag or a toothbrush and reinstall it. If none of this works then the manual says that you have a faulty flow sensor and intex has been out of stock for awhile. However, another to check and make sure that it is not you flow sensor (about $14) you can take some electrical tape and tape the white flap of the flow sensor to the black base. reassemble it and run the salt water system. The filter pump has to be running when the saltwater system is running. If the chorine light comes on on the salt water machine, then you have a faulty/worn out filter pump. If the machine says 90 then it is definately your flow sensor.

You've gotta keep that annoying filter pretty darn clean to please the saltwater pump. I have to scrub my filters daily for this reason. What pump do you have? Mine is rated for 4000gph but I see Intex even offers support for pumps with as little as 500gph.

The most obvious thing besides not having salt in the pool has no stabilizer in it. This is a chemical that has an affinity for chlorine ions and if it is not there the chlorine can be disipated in a few hours when the sun hits it. Another name for it is Cyanuric Acid. It can be purchased in granular form at many pool supply stores or in a liquid form at Leslies. In order to get your pool blue you need to have the chemistry checked at a pool store or with a test kit (either liquid or strips). Don't buy everything a pool supply tells you to buy but start out with vinyl safe shock, stabilizer and salt. The pool store should be able to help you determine the dose. The following is what I would do:
1. Make sure salt is at the recommended concentration.
2. Shock the pool to recommended dose to start killing the algae.
3. Place the recomended dose of stabilizer in the pool.
4. Make sure pump and filter are working properly.
5. Check the pool chemistry on a daily basis until it is ready for swimming.
6. Check the chemistry on a weekly basis and clean the pool and equipment according to the pool instructions.

Smile, you are a pool manager.
