possible purchase used 43 Hatt. sewage system issue

[Canuck Dennis]

Looking at a used late 70's 43 dc, private sale will be importing from US, vessel has rigid PVC S/40 sewage piping to the tank with a y valve set up for overboard, vessel has pvc isolation valve at the hull discharge, just below water line, looks like a good installation. My Cdn surveyor has doubts that would pass for our inspectors up here but feel that if met ABYC it would pass the sniff test.
So I have looked at ABYC and cannot find any specific rejection of the current installation, anyone ever have something like this come up on a survey with rejection ? I do not want to use that hose stuff if possible, the pvc looks like the answer.
Thanks for whatever help you can pass on.

IMHO the pvc is the way to go if it fits. I had that set up on my 46 Matthews MY and it worked great. Surveyor when I sold the boat didn't say a word about it.

installed the PVC nearly 20 years ago on my current 38'. absolutely no issues whatsoever.

I have partial PVC sewage setup on my 1976 43DC and it's been problem free, not sure if up to ABYC code.

You've been away for awhile and had a 43DC if I'm not mistaken, you getting back in the game?

I agree with PVC.

If I understand you correctly you have a below the waterline PVc valve on the discharge. As a surveyor I would suggest that that valve should be a bronze or Marelon valve. The rest of the system in pvc is fine. John

Our regs up here have no specifics on the piping or valves, only the tanks, etc and overboard vents etc.

I like the boat having had one but my big concern is that under our regs new construction standards apply to all imported used vessels, so I think it would be a problem, a surveyor I talked to here says zero PVC anywhere, so if ABYC has no issue then I should be able get relief on it. I see nothing in ABYC disallowing it.

Many thanks for the fast feedback.

If you have to bring a 70s vintage Hatteras construction and systems up to the requirements of a new build to import her, you have á lot more potential trouble than a few runs of PVC pipe. I also question a "surveyor"who doesn't have a concern about a PVC valve being used on a thru-hull below the waterline.

If it passes ABYC why would someone have a concern ? they approve that corrugated crap for bilge pumps which when bent to create a loop just ends up cracking and leaking, it almost sank the Hatt I had in Florida. Marelon is no doubt a better solution.

Your input is much appreciated.

Thanks.

I am curious how you are going about bringing a 30 - 40 year old boat and all of her systems, not just black water, up to complete "new build" standards.
