Hayward Pro Grid DE Filter Repair - Manual Air Relief Assembly Replace or Re-seal

After putting my DE filter back into circuit after winter hibernation I conduction my inspection on the unit, a Hayward PRO-GRID D.E. Filter system model DE2420 as part of a yearly service. I see an issue right from the beginning. A leak forming from the top of the container, not from the gasketed area though.
This is fine though because the gauge was also on the way out and this is original equipment. So I begin the process to remove the old unit, prepare the container top for the new unit and then install and test the new unit.
I ended up needing a whole new unit which called for
Hayward part DEX2420MAR2
If the unit was ok and just leaking from the O-rings the kit is
Hayward part DEX2420Z8A
Same applies for model DE3620, DE4820, DE6020, DE7220

Thanks. Really appreciate the video. I need to replace my Manual Air Release Assembly.

Just FYI, you replaced an automatic air purge value with a manual one. The automatic one has a ball valve assembly that is in the down position when the air is being purged and once the water hits the top, it lifts the ball and forms a seal (supposedly). What ends up happening is DE gets into the ball valve housing past that filter and it gums up the ball causing it to not form a good seal and leak. All you need to do is slide the filter off, clean the ball and reinstall. My concern with the "new" manual one is that if you have any leak in your system, you'll end up with air in the filter and never know about it until you manually open the purge valve. If you still have the old one, remove the filter and i'm sure the problem was DE gumming up the ball.

Great video.. no air relief tube goes connected to the valve...??? Thanks for the video....

Can someone tell me the name of the previous model that he replaced, I broke the air valve screw thingy trying to help my mom.

When I put my new part back on; I was able to turn half of the way, but cannot lock all of the way where both arrows are together . Mine is half was locked, and I see no leaks. How did you get yours to completely turn to the lock position? I can’t use a pipe wrench, because there is no room. 🧐🧐

Great video. I did the same thing today but I have a concern that I was replacing an automatic relief valve with a manual one. If air gets in the unit during operation and I don’t manually vent out the air I could run into problems.

[@retrotechandelectronics]

The older one was manual too, it was just a screw instead of a lever.

[@thomassteitz5640]

Yes there was a manual screw, however there was also this kind of ping pong ball assembly that automatically received all the air when I opened the pool and the filter had no water in it.

Sorry I could not load the pic

[@danarcher3415]

The new assembly is garbage. The old one had a ball that would release air and close when water pushed it upwards. I am looking everywhere to buy the old part.

[@retrotechandelectronics]

The old one did not do a fantastic job of that, also it had metal internal parts that rusted and a screw that required several turns and could easily get lost.

They don't make the old style because of the leaking
