After turning on the pump, outlet valve shoots water across the pool for 2 seconds then slowly decreases. The inlet valve seems to make a vacuum like noise thereafter. Suction is a little weak. Anyone know what could be the cause of this? Thanks!
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 can 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.
You are right, this pump is just too aggressive for the inlet valve. It started in my second year, but completely failed the system in the 3rd year. Lots of noise as air was sucked in the inlet valve. The biggest problem this caused me, beyond airlocks, was my saltwater system was coding that it had a problem with the plates. There was no scaling on the plates as is usually found. upon bypassing the valve the problem went away and the whole system ran smooth and quietly. I wish Intex would upgrade this part to remedy the problem.
Check to see if you have debris accumulation where the inlet hose attaches to the motor/pump
there is a grate inside the houseing that will get plugged with any big items or hair that is vaccumed
Is this a pump, or a filter/pump. There is an "air relief" on the top of some intex filterpumps and you must bleed the air by turning the knob on the top counter-clockwise just a little. Is the filter clean?
Can't help too much more except once I left the water plugin once inside the strainer cap in the pool. Also, a bad seal from the pool to the inlet of the pump/filter could start sucking air and then the pump could get air-locked. sounds like air is getting into it somewhere
Get 1.5" pvc pipe, 2 elbows & 2 rubber reducers with 4 hose clamps. Connect one reducer to inlet valve, then insert pipe down to elbow, Another pipe across to other elbow and short pipe to reducer on pump inlet. The outlet hose can remain stock.

It is a filter/pump. I tried bleeding the air out on the top of the filter with the same result. The filter is whistle clean.
