CS36 head intake vented loop

Hey guys, i've been re-doing all the head plumbing on my CS36 and noticed that there is not a vented loop on the head intake hose. There is for the discharge but not the intake. According to the CS36 manual that's how it came from the factory. It seems as if the intake/toilet is right at or just below the waterline, at least on port tack anyway. Has anyone else noticed this or added one? I have found the CS36 to be a very well designed and thought out boat and can only deduce there is probably a good reason why they didn't do this initially, but it goes against everything that i've read about proper head plumbing installations. Any comments?

thanks.

The vented loop does not go in the intake it goes between the outlet of the pump and the back of the bowl. I had to re-plumb ours to make it right.

Factories do lots of STUPID things, even good builders like CS. Things like installing check valves on centrifugal/Rule type pumps, solid copper AC wire and siphon breaks on intakes among other stupid items.. These are all lack of RTFM events....


You will need to drill a few holes behind the head to route the hose to the siphon break, behind the medicine cabinet, and hoses between the back of the bowl and pump.

Not a tough job but one that should be corrected.

Re: CS36 head intake vented loop

Hey Maine Sail, thanks, i had a feeling that might be the case. And thanks for pointing out that the siphon break should be between the pump and the back of the bowl. I missed that part reading peggy hall's book but went back and re-read it and now i understand why it's supposed to be there and not on the intake.

Re: CS36 head intake vented loop

I'd like to hijack the thread back to Mainesail's comment about "installing check valves on centrifugal/Rule type pumps"...

I noticed a check valve, under the quarter-birth, for my centrifugal/Rule bilge pump on my CS36. I did not think anything about it. I assumed it was to stop back-flow from the almost deck level through-hull. Do centrifugal pumps stop back-flow on their own, by design? or?

Thanks.
