Question about Intex 4000 GPH Filter Pump

1 Answer

I have an intex 15 x 48 pool. The old pump wasnt

I have an intex 15 x 48 pool. The old pump wasnt doing the job so I bought an intex 4000 gph pump. This pump is excellent but there is a problem. The valves dont fit on the inlet and outlet so I bought adapters for them. Another problem, it seems that the adapters allow air into the filter. I took off the valves today and hooked up the hoses directly to the adapters to see if it was the valves leaking air. It is definitely the adapters. I think the inlet and outlet are 1 and 1/4 inch. The ones with the new pump are considerably bigger and dont fit through the liner. So i am unable to hook up the proper directional fittings. Does anyone know what I can do to correct this issue? Or should i just buy a new pool liner with a larger inlet and outlet?

    I have a 16 x 48 intex pool with the 1inch inlet and outlet. I purchased the intex 4000 pump. The attachments are too big for the inlet and outlet so i then purchased the adapters. The plungers are very noisy and allow air to get into the pump. I removed them and hooked the hoses up to the adapters directly. That worked as long as the adapters were new. This year the seal comes loose and allows air to get into the pump. I even tried allowing the top nut to be loose to allow air to escape. This year nothing works. The pump is just too strong for the holes. I was considering cutting the holes bigger and glueing seals on there but i was concerned about creating weak spots in the pool. I am tired of spending money on it so i did the redneck thing. I can say that because well, you might consider me one. I took the inlet hose off the connector and plugged the hole with one of those little black things. I took the hose and run it up through the hole in between the liner and the poles and down into the pool. If you run it over the top it will not work correctly. Take the hose and tie them together between the two sides as best you can to keep the hose in the pool. If you look at the smaller intex pools that dont have holes, that is how they have the pump hooked to the pool. VOILA! You have an airtight inlet to the pump. You do not need to do that to the outlet because its not sucking water its just pushing it. So, just hook the hose up as you wish. When you need to clean the filter, I put wash clothes in the hoses to plug them and voila. No air gets into the filter. Done! It is actually keeping my pool clean this year. Also, i purchased one of those aqua vacuums and it does work great for this pool. Once you get the big stuff, sweep it with a pool broom and the filter will do its job. You cant vacuum these pools with the filter type pumps. Next time, i will purchase a sand filter and be done with it. Happy swimming with less work

I suspect that debris may have clogged the new pump. the only solution is to open the pump chamber and inspect. Flushing does not work.
You may need to repeat this process several times until you get the pool clear. Be sure to utilize any pre filter strainers that you have.

MAKE SURE YOUR SUCTION HOSE IS GOING TO THE PUMP INLET ON THE FRONT SIDE OF THE MOTOR ON THE PUMP. YOUR DISCHARGE SIDE WILL BE ON THE BOTTOM OF THE FILTER SIDE OF THE PUMP. IT SOUNDDS AS SIMPLE AS YOU MIGHT HAVE THE HOSES REVERSED.

Where can I get a new motor for an Intex pump model 637 or 12R


first off water should not be getting to the armature area. be carefull with how you are taking care of your pump.
secondly a 1500 gallon pump is very weak I would advise at least 2500 or even the intex 4000
the most important part of pool maintenance is circulation.

if you have time check into electric motor rebuilding in your area
but sometimes that is more expensive than buying new

also if you have a valid receipt and the pump is less than 90 days old call intex and they will send out a new one within 24 hours
good luck

Is the intex 4000 pump any good.... do you lots filters...


I have the new 4000GPH pump and its awesome! The pump itself needs modifying just a bit. As for your pool, get rid of the plunger valves. They restrict the flow by about 1000GPH or more. There is a plastic grate in the inlet side of the pump. I just took a small file and sharpened the leading and trailing edges to smooth things up. The biggest thing is with the plunger valves. I modified some PVC fittings so I can use 1.5 inch ball valves. When my pump starts up, you see the water moving. I no longer have problems with **** settling to the bottom of my pool. Oh, and it will run an automatic cleaner with ease.
I dont recommend using the 400GPH pump with hoses smaller than 1.5 inches as there will be too much pressure and is likely to cause problems.
