Right at
although your exact pump may not show due to intex having so much product they will have it just make the call.
Do realize the earlier you call the better since it is pool season they are quite busy but your reward for waiting will be to get the part you need

How to fix the Model 635 pump issues

Take that piece of junk and toss it. There are simply no replacement parts available. Replace with a Pentair 3/4HP Dynamo and a 75 sq. ft. filter unit. You can use the existing Intex hoses with 1" couplers and pipe clamps. Buy a length of 1-1/2" flexible spa hose to connect from pump to filter. It'll cost about $400 all told for this setup (if you do the install yourself), but you'll recoup the cost in the 3-4 years you'd spend replacing the 635 annually.

Intex 635. Replaced filter, blead air, actually went as far as removing back plate on pump cover. Impellar looks fine. Runs stong for a few minutes and just stops. Removed hoses checked for blockage,...

Thank you for posting your question here on

Cartridge filters load up over time and no amount of cleaning will restore them to good condition. You can expect to replace the average filter every couple of years...perhaps it is time to replace yours? The baking soda is going to dissolve into the water column so even if it were to cake up in the element it will dissolve quickly; it is not the problem.

Need an impeller for a model 635 intex pump.

You are correct. Intex is in the business of selling new product. If you have the pieces, they may be super glued with about a 70% sucess rate. good luck!

Intex pump 635 is a P.O.S.! How do I hook up a different pump?

I just left the standard intex connection on the pool and I cut the standard connection off of the filter side and I slid the hose over the top of a 1 1/2 pipe and put 2 stainless steel hose clamps over them and it worked fine

Intex pool filter 635 wont turn on

Check your connections to make sure that a lack of pressure is not causing your problem. Also, make sure that your impeller is not jammed, which will cause the filter to not work. These filters are not very well made and usually have to be replaced after a few seasons. They are designed for short term use. It might be time to start looking for new pool filters.

Looking for an intex filter pump

The best solution to this problem not to find a replacement intex pump/filter. I suggest getting a system with a 50 square foot cartridge filter and a 3/4 hp pump such as hayward or pentair offers. You will be amazed at the difference a little quality can make.
