DE leaks into pool; and filter clamp leaks elsewhere

[PoolDoc]

If you can locate an industrial O-ring house, and can take the existing O-ring in, they can make a replacement O-ring for you. I know where you'd go in Chattanooga to have it done, but I can't help you in Riverside. However, in any area with a large industrial base, there will likely be such a supplier.

I do not have a manual for this filter.

Thanks for the advice guys, it is much appreciated. So here's the update. The pool guy came to attempt to fix the leak, says it's the o ring like you guys suggested, so he replaced the o ring. Still leaking, he could not fix the leak with the o ring (still wanted service fee). He said it could be the clamp. If you move the clamp it always leaks at the two areas where the ends of the clamp meets. Any thoughts?

Any thoughts?

Are you handy with tools? If not, you probably will need to EITHER ignore the leak if it's small OR get a new filter, unless you have access to another pool guy with better skills.

Giant O-ring seals are a pain. You have to make sure the O-ring is OK, the top channel is OK, the bottom channel is OK, there isn't ANY debris, that the O-ring isn't 'bunched up', that the clamp is compressing evenly, and so on.

I read through the manual, and reading between the lines on the instructions, Hayward has had some problems with that filter. Among other things, they explicitly warn AGAINST doing exactly what I suggested doing -- tapping the clamp with a hammer. That tells me 2 things:

1. Other people have had problems with the clamp compressing the O-ring evenly enough to get a good seal, and
2. The clamp is plastic, and can be broken if you tap on it (especially, if you don't know the difference between "tapping" and "hammering").

It's possible that your filter is un-repairable. But more likely, it's just balky. Those fiber type clamps will slip when new, and compress things evenly. But, when they are old and somewhat oxidized, they have a LOT more friction, and often have to be lightly tapped to get them to slide and compress evenly. Unfortunately, this is very much a "you have to know how hard to tap; I can't tell you how hard" sort of thing.

Most very experienced service guys could do that. Most young and in-experienced service guys could not. And some old service guys never get good.

So, you're kinda stuck. You could try a new clamp, if they are available. It might work. But, the friction MIGHT be from the filter body rather than the clamp, and then a new clamp wouldn't help much. And, of course it could STILL be a bad O-ring, or a damaged groove. The fact that the leak moves with clamp argues against that, however.

What you NEED is a service guy good enough to either fix, or recognize (and explain) exactly why it can't be fixed. But, you haven't got that.

Sorry.

I am fairly handy, I can't ignore the leak, it let's all the water an debris that is sucked into it flow back into the pool because it doesn't have a good vacuum seal, and there are plenty of pool services here, but few give free estimates and want $110 or more just to look at it. So say $100 for service call plus parts and probably charge me other things as well, and I will be out at least the service fee I'm sure, whether they fix it or not. I had to pay a service charge to this last guy although it wasn't as much as the others, and he didn't fix my problem. Shouldn't there be a "if we don't fix it you don't pay" deal, or is that just wishful thinking?
It now has a new o ring which Waste said is discontinued, so if that's the case and there is a replacement kit how do these places get an o ring for my filter? I mentioned that to this guy and he sounded surprised. I also mentioned to him what you had suggested about cleaning up the channel the o ring sits in of debris, he ignored that idea and did not clean that out.
The clamp is metal, and I was told by my local pool store that there should be a gap between the ends of the clamp, which looking at the clamps on the filters in the store they had about a 3 inch gap, mine is millimeters and very close to touching but are not touching. They said if the ends are touching it may not be getting tight enough to get a good seal which makes sense. Is it possible that I either have the wrong clamp or that the clamp is old, worn and beat up?
Let's hope it's just balky and with some perseverance I can fix the leak without having to buy a new filter.

I didn't do that, when I did hourly service work -- it still took my time to get there; my tools and knowledge to check it out, and it wasn't my fault it was broken.

Update: got a pool company to replace clamp through our home warranty and no more leak. So I don't need a new filter

Great! Thanks for coming back with an update for us!
