In researching pool pumps there are references made to proper sized filter (cartridge type) specified in GPM. I do not see that spec on any filters. How can I determine that based on sq ft data?

A  Answered on 3/30/2017 by InyoPools Product Specialist Andy O.

Hello Wayne- You can reference it if you know the model of your filter, which is located on the sticker on the filter housing. That would pretty much be the only other way.

Does this filter replace the hayward 750-RE ?

Hello, yes this part will fit your current system.

I've purchased many filter cartridges through the years for my cooling pond. Some have been good others not so much. My question is when I use an algaecide and/or clarifier it stains the filter. Does that reduce the function of the filter or is it just discolored?

A  Answered on 10/31/2018 by InyoPools Product Specialist Lennox H.

Hi, Wayne. If the cartridge is stained, then the cartridge could be still functional. It's hard to confirm without seeing how the cartridge functions when it's reused.

Sorry this question is not pertaining to the item. I just installed my new motor pump and it seems to work fine. However. my filter pressure gauge is not working and it wasn't working before I replaced the new motor. Thanks in advance

A  Answered on 6/16/2019 by InyoPools Product Specialist Lennox H.

Hi, Leon. It sound like the pressure gauge will need to be replaced in order to make sure your filter is running properly.

Pool water was not filtering well.

Written on 5/6/2020 by Guest

My pool water was not filtering sufficiently even though I had the pump ranking for 7 to 8 tours. I went online and read INYO Pool's online tutorial which suggested that I change the pump's filter. I browsed the website and found that I could purchase two filters for the price that my local pool store was asking for one. I ordered the two filters and now I have an amazingly clean and bright pool. I recommend INYO Pool products as their customer service and prices are incomparable.

Old filter and dirt was coming out of the returns to the pool when vacuming.

Written on 5/22/2017 by Guest

Hayward C-750 cartridge filter. The new filter fit fine and replacing it is very straight forward. However, I was still getting dirt coming out of the returns. I double checked the filter for torn pleats and found none. I double checked the filter body and lid for cracks and found none. I did a lot of research on the internet and looked at the manual/parts breakdown but nothing was shown that could let dirt past the filter. I drained the filter body and after a close inspection with a flashlight I found a small round white piece in the bottom of the body that was letting water past the filter. There is a 3/4 in diameter hole in the bottom of the body that has a plastic plug in it. This plug was blown out. I put a rubber plug in this and it fixed the problem.
It was very frustrating because I found nothing on the internet or any of the manuals that indicated there is an opening in the bottom of these filter bodies with a plug that can go bad.
If you have dirt going through the filter I would recommend checking this first.
