I have a Hayward put in 2003 and need a new filter element cluster. How do I determine which size I need?

A     Answered on 12/10/2015 by InyoPools Product Specialist Brian M.

If you are lucky, the sticker on the front of the tank will have a mark next to your model number. Barring that, if you measure the length of one of the grids ( top to bottom ) and then multiply that number by 2, that is the square footage of your filter. Example : if your grids are 18" long, you have a 36 sq ft DE Filter.

This was done while the pool was closed so the prerequisite steps of relieving pressure, draining and opening the filter were already done, and the filter assembly was already removed.

1. Using a wrench or pliers to hold the bolt at the bottom, loosen the threaded rod that runs through the filter assembly. No need to completely remove the rod.
2. Carefully pop the top plate off the individual filters - in my case, a couple were stubborn, but with some gentle persuasion, they came loose.
3. Pay close attention to where the short filter fits. It isn't that complicated if you look at where it fits in relation to the gap on the bottom plate. Also note how the screens fit in between the spacers/holders in the bottom plate.
4. I found it easiest to remove all the screens, wash off the top and bottom plates, and then re-assemble. Again, make sure the short screen is in the correct position.
5. Reposition the top plate - it can take a little bit of fiddling to get all the screens aligned with the holes in the top plate, but take your time and you'll get it.
6. Again, with a wrench on the bottom of the threaded rod, tighten from the top.
7. Confirm that there is a space for the outflow tube from the gap in the bottom plate up to the connection in the top plate. If not, you installed the short screen in the wrong place.
8. In the filter body, make sure the o-ring where the filter assembly meets the outflow tube is in good shape and is well lubricated.
9. Press the filter assembly on to the outflow tube
10. Re-assemble and recharge your filter per the instructions.

pool green and cloudy and could not get it to clear up

Written on 3/5/2017 by Guest

After changing the DE and still no improvement, I decided the filter was not working. So I pulled the top half off the filter and found that 5 of the grids were broken off where they connect to the outlet header of the filter. This allowed the water and the new DE I added to pass right through the filter and back into the pool. I went to INYOpools on internet and ordered a new set of grids for my filter and associated o-ring. I installed the new grids and new DE and within 2 days the water was clear as it should be.
