Pool pump intex 51 pumps water but return flow is low

I have a Intex pool pump model # 51, it pumps water but the return flow is very low to none, the cartridge is clean

    I just bought a replacement pump for the pool (original 530 gph pump failed for second time). New pump is 2,500 gph. The return port is sucking in water at the top of the port while discharging water through the rest of the port, making a mini-whirlpool. The water level is just above the port. I ckecked for leaks in the piping and found none. Had to use an adaptor kit as pump hoses are larger than original hoses and ports for the pool. The adaptor utilizes a rubber gasket and threaded ring to clamp down on the port stub. I can't figure out why the rreturn port would be sucking in water at the same time that it is discharging water. The sucking noise is annoying after a short time and I am concerned about debris getting sucked into the return side of the pump as well as the suction port.

    Thanks

If you cartridge is completly clean then start by disconecting the out tube that goes to the pump housing
sometimes debris gets caught there entering your pump.
a little hair causes other things to back up

once you are satisfird that those 2 things are ready then close it all up and open the bleeder cap on top of the cartridge holder

Now let water in from the suction side
when water starts coming out of the bleeder cap then open the return side
Now turn on the puimp
let it run for 20 seconds and then close your bleeder

Should be working fine after that.

dont forget to leave the bleeder cap alone on the bottom of the canister unless you are draining the water from the canister to clean it. As soon as you are done close it back up

How do i clean and backwash my krystal clear saltwater system model cs8110 pool. Also it is very cloudy and I cant see the bottom of my pool


Hello... Is this your first pool? If so, do you have a local pool chemical supply company? They will test a sample of your pool water with way better equipment than the test strips... Than they will tell you exactly what you need and how to apply them... This is my 4th year with this salt system and 18'x 4' intex pool... Starting them up is tricky and it still takes me weeks to get it right... But the pool store told me how to start it up for next year so hopefully it won't take as long...
The phrase backwash referes to cleaning the filter... With the intex filter/pump system, that is the filter cargtridge that inserts into the pump/filter housing... Close the pool valves, open the filter cartridge housing, take the filter out and hose it down with a garden hose... Before you return the filter, dump out the nasty water sitting in the filer/pump housing... the Return the filter, screw back on the cap, open the pool valves and open the vent screw on top of the filter cartridge housing lid... This allows the pool water to flow back into the filter/pump and removes unwanted air pockets in the hoses... Once the water flows out of the vent screw, screw it back down to stop the water coming out... Now your down backwashing the filer...

Hope this helps,
Dan

After modifying our 20x 48 Summer Escapes pool to utilize our Intex Saltwater system - why is the saltwater pump showing low flow?


Index salt chlorinators need a certain flow rate. Check the flow rate on your pump to see if it is strong enough.

Can i use a sand filter with the intex krystal clear saltwater system?


Yes you can.
The saltwater chlorinator is connect to the outlet water pipe from the sand filter before the water returns to the pool.
Depending upon the model of the saltwater chlorinator It may need to be mounted horizontally or vertically, check with the installation instructions..

What is the recommended end-of-season maintenance for the chlorinating pump?


According to the Intex website, the following maintenance is required for this product:

The Intex Saltwater Pool Systems are designed to operate with a minimum amount of maintenance. It is recommended to always turn the pump on prior to turning on the Saltwater Pool System (see Owner's Manual) unless the chlorine generator is part of a combination pool and filter set, to ensure that air pockets are eliminated from the hoses, and that water is flowing through the unit. In addition, the electrolytic cell should be examined and cleaned if necessary. The frequency of cleaning will depend on the local water conditions, pool usage conditions, and length of time the Saltwater Pool System is operated each day. (See Owner's Manual.)

The Intex Saltwater Pool Systems contain several features that minimize maintenance requirements:

1.) An automatic self-cleaning cycle: The Saltwater Pool System automatically undergoes a self-cleaning cycle to maximize the operating length of the electrolytic cell.

2.) Safety diagnostics: the Saltwater Pool System will alert the operator to three conditions that could result in poor operation: Low water flow through the unit, Low Salt level in the pool water, High salt level in the pool water. If any of these conditions exist, the system will sound a buzzer, and flash a digital code on the control panel (Model 8110) or a Red LED will light up. (Model 6110).If the condition is not addressed, the system will automatically shut itself off to prevent damage to the unit.

I have a 15x 42" intex metal frame pool an i also


Most likely you are not. The manual is very conservative!!! I have a 14000 gallon pool and I run my intex salt system during the summer at 10 to 12 hrs pump and 8 to 10 hrs chlorination in between those 12 hrs and my pool stays very clear. But..... If you don't clean the unit and let it alarm for low flow, low salt or not run the unit log enough, you WILL HAVE GREEN WATER!!!
Hope this helps, If it does, please rate the tip!

Pool pump shutting off/tripping the circuit breaker


What kind of pump are you using?
Sounds like the Intex is restricting water flow there by heating up your pump and shutting it down..
You may need to re plumb everything to handle the flow.
Intex hoses and fittings are different than the industry standards just so the can make you buy from them
Do what ever it takes to get good flow

I cannot find user manual for my intex salt water system. What side of pump does it attach to?


You have an inlet side, (where pool water is brought into the pump), and is typically the lower of the two. Then you have the return, (where the water comes back out after being filtered). As the previous person noted, you'll need to observe the arrows indicating flow direction on the SWG and it will be on the return side of the pool. Additionally, you can go to the INTEX website, and they have the same setup video that should have been provided with your system. Hope this helps.
