DE Blowing thru

[candab]

Ok, first of all, thanks for letting me on, I've checked these forums several times for helpful info. I am a pool guy, albeit inexperienced. I started my own cleaning and maintenance service six years ago, shuttered it because I couldn't grow it faster than my family expenses, and recently reopened it as a sideline. I currently have eight customers and have my own diving pool as well. My personal pool is 35'x17'x10' kidney shape with spa, don't remember exactly but approx 28k gal. Jandy equipment, standard trichlor and cal hypo chems.

Anyway, my issue isn't with a customer thankfully but my own pool filter. I did a cleaning on it and it had a cracked manifold along with some grids which had collapsed corners (it had been severely neglected for a long time because I was an over the road trucker, don't judge me! lol). Anyway, I determined that the five old grids which had corners collapsed were still functional for a while anyway (I am waiting for wholesale price approval from the supplier) but I bought and replaced the manifold.

I put everything back together, had a leak in the joint, pulled it apart, relubed, fired it up again and added DE. A pretty large amount came back out through the ports and the spa. I thought I had inspected the grids well enough that I found no tears or holes in the corners before reassembling it. I had also replaced the stand pipe O ring. Do you think this is a simple case of me missing a large tear or hole or is it possible I missed something?

Hi and welcome to the Pool Forum!

I just wanted to say hello and welcome you but also to caution you a bit. We have lots of 'pool guys' who come to our forum. Sometimes they are trying to sell things which is a big no-no. Others come to give chemistry and maintenance advice which is also frowned upon as a newbie. Especially since our methods are pretty different from what most of the pool industry believes.

So, please do us both a favor. Feel free to read and ask questions if you need some help with something but refrain from giving chemistry advice that differs from what we teach here on the Pool Forum. That is one thing that sometimes causes pool guys to lose their membership. Hope you understand.

I'll let someone else help you with your question about your DE filter.

Again, welcome and hope you enjoy participating with us!

Thanks watermom. I just tried the edit sig link and it said I don't have that privilege yet. I will try to refrain from giving advice, I definitely don't sell anything, but I would like to add my views of what would be possible diagnoses of others' issues if possible. Like saying that there might be low or no CYA in a pool that eats chlorine overnight is reasonable and typical first-thing-to-check-easily response,.isn't it?

[Watermom]

Yes, but we prefer that newbies not start out giving advice until they have been around awhile. It gives them time to read and get to know what we are all about. So, for now, just enjoy reading on the forum but hold off on offering advice. Also be sure and read over on our sister website www.poolsolutions.com. Lots to learn there as well.

Hope you understand our position on this. Thanks!

I'll have to check on the signature issue and get back to you on it.

Hi Candab;

Without knowing the details of your filter, I'm not going to guess. But I'd recommend that you find the complete parts diagram online, go over it carefully, and then disassemble the filter again, looking for anything broken or misplaced. I've fixed a LOT of things that way, myself.

PS -- let me know if you are unable to post a (moderated) reply to this thread. I've found that some of the permissions aren't working the way I'd expect, but haven't been able to determine just when the problems occurred.

The filter is a Jandy DEL60. I imagine that one or more of the five older grids are perforated and I just missed it. Just wanted to know if anyone else has dealt with this in their dealings with customers. I would rather not have this happen when I'm doing a cleaning for someone other than myself. It would be nice if the pool company would get off the stick and approve me for wholesale pricing. It would save me a bunch of money.

There might be low or no CYA but that has nothing to do with overnight chlorine loss.

Overnight chlorine loss is not related to CYA level but to stuff in the water being oxidized by the chlorine. A pool that loses all it's chlorine during the day might have insufficient CYA.
