How does one know if the water flow is adiquit?
you can not just hold your hand at the discharge and say this is good enough.
I would start with turning off the system and cleaning the filter cartridge with a strong garden hose.
Now remove the ring that holds the sensor in and remove and clean it with the hose make sure it swings freely

now check at the front of the pump where the in tube connects
there is a plastic sort of screen molded into the motor
debris and hair gets lodged there that the skimmer doesnt catch or just goes to if you dont skim
Put every thing back together

open all bleeder caps except the one at the bottom of the cartridge case

open disharge tube first and wait ti'll water comes out the bleeders
now open the inlet tube
now turn pump on
wait 30 seconds and close the bleeders

This should do it for you

Started my salt water system soon after adding a bag of salt. Now I'm getting a low flow warning even though there is plenty of flow. What could the problem be.

You may think you have good flow, but the sensor that always is confirming the proper amount of flow is telling you that it is not!

Especially if you have a Toy system. The filters that come with these systems are way too small and will clog quickly and provide a restriction of water flow.

Test naked Try this (after waiting 24 hrs and if problem still persists) take the filter out of filter housing and see what happens? Does the error go away? If so, then replace with "New" filter, not a cleaned one. Filter elements get clogged, with metals & minerals, that you can't see with a naked eye. It may look clean, but is not.

If all this is still creating a problem (with no filter element in place) then you may have a faulty flow sensor?? But I would not go there immediately because the sensor is probably just doing its job.

Just purchased and installed Intex salt water system. It shows low flow and now, after 5 days of installment, the water is completely green (expecting Swam Thing to come out!) I need your guidance to...

Seems like you may not have the pump and the salt chlorinator in sync... If your water is dark green and not a big pool, you may want to drain and refill, if you have a large pool, you may want to shock and then try the following...
1.Make sure you have added the correct amount of salt...
2.Set your timer for your pump for 12 hrs.
3.Wait 15 minutes and then turn on your intex salt water system..
4.Set you hrs of operation on your salt water system for 10 to 11 hrs...
5.After running the system for 3 days, check your chlorine level..

If water clears and chlorine level is high, adjust the time.. You will have to re-sync the pump and chlorinator.. If the pump turns off before the chlorinator finishes it's cycle, you will get a "LOW FLOW" alarm..
I hope this helps and good luck.. Please rate and comment on the information provided.

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.

I have done everything the manual says, but my saltwater system will not stop blinking error code 91. The salt level is fine, and the cell is clean. Do I need to replace the cell. My pool is now green and...

Bummer!!! Looks like you checked both things that would cause the code 91 error for "Low Salt". Here's what I've done to solve my low salt "91 code in the past.. I overshoot by 1/2 bag = 20lbs of the recommended salt add quantity when the code appears. Calculate by using this formula..
.0067 X Pool Gallons. I have a 14,000 gallon pool and when I get the 91 code for low salt, I add about 110 lbs of salt. Manual says 93 lbs...let it circulate for 24 hours by running the pump only and then start the chlorination cycle.. Before doing this, you MUST make sure the cell in clean.. If any calcium buildup inside, it can give you a false "Low Salt" alarm.

I hope this helps!!

If this helps, please rate... Thanks

It says low flow, how can i fix it. its a Intex Automatic Salt Water System for Above Ground Saltwater Pool

After five years of using our pool each summer, we assembled it last week and I kept getting the "low flow" warning (with irritating beeping) even though the water flow was very good. I disassembled the unit and checked the flow switch, and found that the switch itself was the culprit. Here's what I did: (this is probably not recommended by Intex...) I unscrewed the main portion of the salt water purifier (the part with the digital display on top) from the base and lifted it up to expose the circuit board and wiring. All the fuses were intact and everything looked good. At the bottom of the circuit board, about an inch from the right edge is where I found the connections for the flow sensor. One was marked "flow" and the other was "grnd". I removed the plugs that run to the slow switch, closed the circuit by making a direct connection between the two plugs, and voila! No problem. I ended up cutting the wires about 1-1/2 inch from the plugs and connecting them with a wire nut, then I plugged them back in. The unit is working perfectly again.

If you attempt this, make sure the unit is unplugged and be careful when dealing with the circuit board. Don't be intimidated, it's not a high-voltage connection you are working with, you are simply closing the circuit and telling the board that the switch is closed as it would be with adequate water flow. I was comfortable making this "modification" and bypassing the flow sensor because we have several years of experience with our pool and because I clean and swap out our pump filter every day during summer, and because we know the difference between strong and weak flow just by checking the inlet and outlet ports in the pool.

I hope this helps someone! It took care of my problem. Best of luck.
