?     Asked on 7/7/2020by Susan

I have a Hayward DE4820 I believe and my pressure gauge is not working this year. Can I just replace the gauge and not the whole Manual Air Relief assembly? My owner manual says part #ECX2712B1

Hi Susan, yes you can replace just the pressure gauge being part number ECX2712B1

How does someone go about replacing this valve on their own. What tools do I need to complete this valve change out for a new one.
 Reply

A  Answered on 9/10/2019 by Industry Professional

If you are unable to grip you would need would a large pair of channel locks.
 Reply


A  Answered on 9/10/2019 by Industry Professional

No tool will be needed. You would just turn counter-clockwise to unthread.

I have an older model DE Filter, model 4820. Is this manual airrelief valve goining to fit my unit. Also the old original unit has a auto relief valve as well, my question is if the DEX2420mar2 will work as a replacement and it doesn't have an automatic air relief valve how does the air escape when it turns on automatically and there is no one there to manually relief the air.
 Reply

A  Answered on 6/16/2018 by InyoPools Product Specialist Lennox H.

Hi, Joe. This Manual Air Relief Assy - DEX2420MAR2 will fit your model filter. However, is not equipped with an automatic air relief feature. It will have to be manually opened and closed.

I have a older Hayward DE filter DE 2420L with DEX6000DA grids from 2002/2004. My filter has a Air Relief Assembly DEX2420AR(part number) with the ball inside it. Will this assembly fit my older DE unit. If so do I need to do any thing with the ball assembly or when I take out the old assembly all is connect and just replace it with the new assembly.Thanks for your time

I broke off the screw in air relief screw. I was able to thred it so it stays in. Is there anyway to get the screw. Part all the way out and put a new one in or will I have to replace the whole assy
 Reply

A  Answered on 6/17/2016 by InyoPools Product Specialist Alan M.

You can try making an indentation in the threaded portion so a flat head screw driver can fit in the slot and back it out. Then you can replace it with the Air Relief Ass'y W/ O-ring (ccx1000v).

Hi. Can you get this part without the gauge? I ask because I just got a gauge and now I discover a crack in the top of the housing I assume this is why I'm not getting any pressure.
 Reply

A  Answered on 5/29/2016 by InyoPools Product Specialist Matt S.

Hello, John, this part is only available with the gauge, and not sold separately.

?     Asked on 6/26/2015by david

why would water come out of the top of this? what is the purpose of the assembly?
 Reply

A  Answered on 6/28/2015 by InyoPools Product Specialist Lennox H.

Hi David, If one of the o-rings is bad water would leak out of the  Air Relief Assy. The Manual Air Relief Assy (DEX2420MAR2 / DEX2420MAR) is used to monitor the pressure in the filter and to bleed out excess air out of the filter.

how difficult is it to replace this part.
 Reply

A  Answered on 6/26/2015 by InyoPools Product Specialist Hector F.

This part is not too hard to replace. It literally just unthreads and comes off. It isn't too much to unscrew it either. Just release the pressure, unthread, and reinstall the new assembly.

I recently noticed that my filter had water on the top half

Written on 8/22/2021 by Guest

Turn off pump and then open pressure relief valve and wait for all air to be released. You can tell when this is done after the hissing stops and the level of water drops in the pump.
Next you need to turn the old pressure relief valve (PRV), in a counter clockwise direction about a quarter turn until it unlocks as is indicating on the filter body. If you are unable to turn the old PRV by hand, you may need to get a large wrench of channel locks to grip it and get more leverage on it in order to turn and remove.
There is a spare o-ring with the new PRV which I did not use since it wasn't the same size as the one on the filter body. Since my old ring seemed to be in good condition, I just reused it and put the new PRV, which has an o-ring already on it, in the hole and turned it clockwise until it was in the locked position

Stress fracture/leak in housing at the gauge

Written on 4/26/2017 by Gary B.

This is an easy fix--Grasp the old assy. with two hands, turn counterclockwise and it releases. Remove it.
Take the new assy. apply a judicious amount of Jacks silicone lube on the gasket. Place in the opening and turn clockwise-----VOILA!!!!
