AC Pump Trips Main Breaker

I ve had 3 surveyors on boats with schedule 80. It passed.

I think I commented before, Grey or schedule 80 PVC is not an issue. Surveyors usually do not have a problem with it.
It's the glued assembly that they may have the problem with.
Mechanical assembly is always superior to chemical adhesion.
Still, I lean to nylon or marelon fittings for greater security.

As i said, 3 surveyors, no mention. If it was an ABYC issue it would have been on the surveys.

Years ago I had a surveyor who did gripe about it below the water line on a sink drain.
I had to prove it was not below the water line, He still gripped but did not write it up.
Since then (early 90s) I don't glue any plumbing, anywhere.
Had another purchase surveyor gripe about white pvc fittings fitted into a drain manifold on a customers boat (late 00s). Factory installed (SeaRay). Those were changed out with marelon and hose, all good then.
Funny thing, found the same thing on a later Hatt 70 a few years ago. It was never mentioned on any surveys. That boat just sold last month. I was told a perfect survey.

CaboFly can always call his past surveyor and ask.

Just imagine; what/where is the usual pvc failure at home?
For me, usually the glue joint.

I'm glad you called him.

Now that's funny..

You're missing the forest for the trees.
I just checked the specs of that pump: it's rated for a max head of 27 ft, and can withstand a max internal pressure of 25 PSI.
So, we are talking of pressures which are laughable, for any half decently glued pipes.
In other words, even if you would seal the discharge completely, all you would get is an overheated pump motor, which will eventually fail.
If you can name any boat in real world whose glued pipes of A/C raw cooling circuit exploded and sank the boat, I will eat my hat.

PS: this is not to suggest that glued pipes are better than threaded, mind.
I'm just saying that the gripe against glue is totally unjustified, in this case.
And anyone who think that glued parts are by definition unsafe should never board a plane, BTW.

I'll just add this small piece. I've seen glued fittings come apart in my hands. Glued applications are only as good as the glue process someone follows. Many simply pick up pieces and add glue. No emory paper. No cleaner. Just glue. Hard for any third party to interpret what they see when they view a glued joint.

So I get the concern. Always go thread where and if you can.

Absolutely.
But by the same token, I've also seen fittings glued with the right sealant and following the correct process, that were simply impossible to take apart - to the point that if forced, the pipe broke elsewhere but not in the glued part.
When I said that the gripe against glue isn't justified, I didn't specify "when used properly", but that was a given.
I appreciate that threads require less attention/skill, so in this sense are safer/easier to use.

That's a sort of catch 22: if the glue doesn't hold, of course the fitting can fail completely.
BUT, if the glue doesn't hold, that was a Mickey Mouse job, to start with.

Can hit this ball back and forth all day without any meaningful outcome. The rub with the glued fitting is this....you come upon it as a surveyor or owner or adjuster or whatever....you likely were not there when the fitting was glued, and you cannot certify the quality in which that joint was created.

Yes, I trust my own glued fitting, but if I'm at the store buying the fittings, I am buying Sched80 threaded fittings if I have the option. If I am forced to glue, I am planning to replace the glued fitting at my first reasonable opportunity.

Yall have been hitting something back and forth.

But CaboFly (THE O P) did nip it in the bud and meaningful outcome came 4 days ago.

Your post bueno. The back and forth, no bueno.

Life is good brother.

17 years old glued schedule 80 on manifolds between two pumps and 3 chillers. No leaks, no issues. Flushed every year.
