My intex 637r pump is not pulling the water through to the filter and letting it discharge back into pool could it be that the pump and hoses are sitting to high on the ground and not far enough under the water level

Air release valve for air trapped inside filter chamber

Intex 1000 GPH Easy Set Pool Filter Pump Instructional Guide 637R

The link has a set-up video for the 637R pump. Make sure water flows out of the air valve on the top of the filter cover. This will purge air out of the filter and prime the pump. Hope this helps you....

SOURCE: Problems with Intex Krystal Clear Model 635 Pool Filter Pump 1500

No, the pump should not be noisy. It sounds like you have picked up a foreign object in the pump housing. you may have to pull the face off to determine. OR the pump/motor is indeed defective and should be returned.

SOURCE: High ph, algea, salty taste

You are going to need to buy chemicals anyway (acid for sure and probably algaecide) so find a good pool store tech and have them test your water and recommend the proper doses.

In summary though, you should not taste the salt in the pool and being able to means the salt content is to high. Chlorine generators will not work if the salt is to high and the fix is to drain water and dilute the remaining water until the salt content is no higher than max. No chlorine could explain the algae.

Generators also cause the pH to rise over time so you will need to keep acid on hand to counteract that.

SOURCE: Salty taste, high ph levels, algea and have shocked pool twice

I'm just now setting up my Saltwater generator...so don't have your problem - yet! Local pool guy tho said with the saltwater systems you need to add dry acid to the pool almost weekly to keep the ph down. Sounds like what you're experiencing. The dry acid was cheap and came in small-ish containers, should last long time.

HTH.

SOURCE: My intex saltwater system does not fit on my

unfortunately every thing you mentioned is not reaaly important.
Bottom line is that Intex has there own size hoses and prevents easy installation with other manufacturers.
You will need to make a trip to home depot and buy a basket full of fittings and keep trying till one works

Wish to upgrade cartridge filter pump to sand filter pump. Pool size 15' X 48" / pump 1000 gph - 637R /Item no 56945 Which intex sand filter is the best one?

First, understand that sand doesn't filter as finely as cartridges, so "upgrade" may be the wrong word. Cartridges filter down to about 10 microns, sand filters to 25-30 microns. (i.e.the cartridge will catch particles up to 3X smaller than sand will.)

If you still want to change, get the biggest sand filter available that you can comfortably afford. For superior results look at above ground pump/filter packages built by Hayward or Pentair. Intex products are just built to margin and are not designed for long term usage.

How do i hook a vaccum up to my model 604 filter pump?

You should take your vacuum hose and plug it into the hole in the bottom of one of the skimmers. Fill the hose with water first or your pump will loose suction. I fill my hose by putting the head of the vacuum in the pool. Take the other end and hold it over a pool's discharge port (where the water comes back to the pool from the pump. When the air bubbles stop, put your hand over the end of the hose and move it to the skimmer and connect it.

That work for you?

Thanks fo your visit today.

My vacuum for my 18' intex pool doesn't work right. Goes good for first minute and then suction is very low. Keep getting air in line. How do I solve this?

Make sure you have your tube completly filled with water. hold one end at the discharge while pump is running when full make sure both end of hose stay under water while connecting. I also leave the bleedee cap unscrewed just a bit to let air escape from the system HAVENT HAD A PROBLEM YET
