CPVC Ozone safe????

[james s_]

Does anyone know? I am contemplating using some 1/2" CPVC for my airline on my skimmer and injecting Ozone approx 5-6" from the venturi using a T in the CPVC.

Also where can I find a 1/4" barb fitting that is Ozone safe? Home Depot has brass fittings but I would much rather use plastic.

Not sure on ozone safe but I know that Lowes has a good selection of cpvc items including 1/2" stuff.

pvc isn't ozone safe, so I doubt cpvc is.

Hmmm, I was under the impression that pvc was????? Ok well I installed the air line with CPVC so I guess I soon find out. Next worry is if the needlewheel will hold up to ozone, Good thing I have an extra one.

lol, can't help you with the needlewheel!

Well this is how I plumbed the air feed for the skimmer, hopefully the ozone wont eat thru the cpvc.....the ozone line will be tapped into the cap above the pump.

There is NO WAY PVC is ozone safe. Where did you find that? It get brittle, and will crack.

So what am I supposed to use???? Come on guys we don't need arguments, we just need solutions Does MRC make anything for this?

either way, I dont see that acrylic is safe... and it clearly doesnt eat through a skimmer... I dont think the PVC would just melt. it might get brittle, but thats the nature of the beast I thought. long as he doesnt start testing its strength with a hammer, shouldnt be a problem.

Not functionally true. It becomes so brittle, that even slight stress cracks it. I dont know how well it holds ozone gas before that either.

James, I have no idea what sizes they make norprene tubing in, but its worth looking into.

But you're talking a long time- years and years before it gets to that point. I'd say to go ahead and use it- just be prepared to replace it after 3-5 years. I used JG fittings for my old setup, and they lasted 3 years until I took it apart; the pieces snapped when I unscrewed them (but were functional up until that point).

As Chris stated, PVC and CPVC will get brittle over time so just be prepared to replace it along the way.

Thanks for the link Mike! That has all the goodies on it.

I am wondering if it even worth it to run the ozone thru the skimmer? Maybe a reactor would be the way to go??? Is there a cheap DIY reactor that could be made?
