Hayward cartridge filter manifold cracked

[nick.simpson19]

Hello,

I am new to pools , and I’ve learnt a lot since having my pool. So before we got into the swimming season here in lower Alabama I thought it was time to clean my cartridge filters.

So I watched a few you tube videos and today took the top cover off and the manifold is cracked on the top, see pictur below.

In the meantime I’ve put it back together, but I’m assuming by having this crack in manifold that the filter ain’t working to good.

some questions
1. Were is the best place to buy spares from? O rings, manifold, new filters?
2. Anyone have some instructions for replacing?

Thanks

Nick

Google has lots of hits. You need your exact model number.

For one stop shop with great customer service call InyoPools. They are usually a great help to forum members.

Thanks man! Your always my savior! Thanks for your help.

Should I replace cartiridges and all o-rings while I am at it? Is it quite common for these manifolds to fail?

 

[mknauss]

O rings are always a good idea. The cartridges should last a long time. Failure is normally the plastic end caps finally deteriorate.

Not sure about the manifold. It should not be under any stress if installed properly. Be sure to not over tighten anything.

NIck,
The manifolds should not crack. I bet it was dropped, cracked some, then if the filters were not cleaned and became clogged, the water took the path of least resistance.
I would definitely replace manifold. If your cartridges are less than a yr old or the rings binding them are all in good shape, just clean and replace. Make sure you buy the proper type o-ring lubricate for pool O-rings..

Good luck, tstex

I’ve been the house 6 months, so I’m guessing they were broken before we moved in how often should I be cleaning the cartridge filters? I’m guessing my current 6 months is to long

Some of the bands have started to fail on th cartridges.

You should clean your filter when the filter pressure rises by 25% over the clean filter pressure.

As suggested, clean filters when 25% above max limit, but since your bands are breaking, I'd order a new set along w your new manifold. Replace cartridges and clean the old ones and use as s back up or rotate. If the bands completely break or ends are too cracked, then you can toss.

Order your silicone too Lube your O-rings...they don't have to be lubed all the time, only when the old silicone gets dried or flaky - Lube as needed

Good luck

I think you are right that manifolds "should not crack", but in my experience, they do. I have replaced two in the past year and a half. I believe they crack due to pressure issues.

Replacing 2 in the last yr and a half is WAY TOO MANY. Is this for that same cartridge filter? If so, something is wrong ??

No, sorry if that was misleading. I replace 2 different ones on 2 different filters. It's hard to believe that plastic can crack but it really does.
