Question about Pentair FILTER TANK BOTTOM, 48 SQFT

1 Answer

After cleaning my filters, the top case of my Pentair filter will not go back on properly (tight fit)...instead it wobbles which makes it difficult to get the brace around it and tighten. Any suggestions?

With the top off close the air bleeder then turn the pump long enough to fill the tank then set the top on the filter. As the water tries to drain to the pool the vacume it creates will pull the top tight. While you have this suction place the band clamp and start to tighten. You might have to try this once or twice but I'm sure it will help. Good luck.

I have a 6 year old Pentair Dynamo 340210 pump for my above ground pool. The past 2 weeks, after I back washed the filter- the pump seem to not be pulling very much water into the filter and it is not...

It sounds like you have a air leak on the suction side. I am assuming the pump is operating at full speed. Check for a cracked line especially around fittings. Try cycling the back flush valve as well. I hope that helps.

My kia optima leaks engine oil around the filter

remove the filter and be sure the is a rubber gasket attached, if so rub a bit of oil on it before replacing, being certain that interior threads are clean and not stripped ( if so replace filter) only turning hand tight, no not overly tighten.

My great white pool clearner is not moving in the pool what might be the problem?

There are several thing that you can check. Be sure that both the filter pump and booster pump
are on and working properly. They might need to be cleaned. Also, check the wall fitting screen for debris and rinse clean. Test your pool cleaners wheel RPM and make sure that it is in the desirable level of 28-32. Make sure that your back-up valve is cycling. Check all the hose connections and
swivels for leaks that can cause loss of water pressure.

I just replaced the tires on my Legend Platinum because the originals were totally wore down. I unplugged the pool fitting to clean out the little filter. After I reseated the connection (nice and tight)...

You may need to replace the wall fitting and the fitting that houses the screen. If you look at the fittings and find a tab broken or the track it runs in hurt that will tell the tale. The least amount of damage will cause pressure loss and the noise you hear.

Difficulty in putting filter back together in getting clamp ring on

When reassembling the grids place the manifold upside down on a five gal. bucket. Then assemble that way, this will hold the grids stable and make that part much easier.
When that is done and in place. Lightly grease the tank "O" ring. Then run the pump to fill the bottom of the filter with water. With the air bleed closed set the top and lightly push down. As the water inside runs back to the pool the suction created will pull the top down tight. Then just set the ring and tighten.

When pump starts up i get a small cloud of de in my inground spa every time it starts up. I have had the filter looked at by a pool repairman every thing looks good he is stumped as to this is happing ...

If all your grids are in good shape you have to look at your manifold real close for cracks and around the internal air bleed. When checking your grids be sure the nipples that go into the manifold are also in good shape and when reassembling make sure all fit comfortably and get them tight. Hope this helps, good luck.

Lg washer wm2455h leaking from bottom filter housing; there's nothing in the filter itself. Filter has proper gasket.

Make sure the drain hose is not plugged by lowering the end below any water in the machine--it should flow out freely. If ok, look carefully at the filter housing for any warping or cracking of the plastic lid or case. Make sure the clamp fits tightly. If water does not flow from the drain hose properly, try 'back-washing' the filter element--you may have to replace it if you have difficulty.
