The ball valve on the A/C thruhull seems to have failed. The handle still moves to open and close position but feels “wobbley”. Valve also seems to remain closed even when handle is on open position. After some research, it seems this factory installed valve is of brass construction with chrome plated ball, so not too surprised it failed after 3 years. I’ve thought about reworking the whole thruhull/valve/strainer arrangement as it has a small strainer for 3 a/c units, is really an in-line valve being used as a seacock (questionable approach) and because of the brass construction. Was wondering if anyone else has replaced or improved upon this arrangement?  www.23hq.com/Solana/photo/50971185/original www.23hq.com/Solana/photo/50971403/original |

puravida,
The Jeanneau factory installed seacocks are notoriously poor in quality. It's scandalous. There are plenty of examples of this on this site. The "good" news is that yours has failed closed which means your boat isn't in any danger of sinking. Since it's below the waterline you're probably going to have to haul out to replace it. While its out you should probably inspect the rest of the seacocks and replace any that aren't in good shape.
It looks like the engine raw-water strainer in the same picture. Perhaps adopt a similar arrangement for this hose? Or even plumb them into the same hose?

Yes, i’m familiar with the Jeanneau seacock issues. Seems like such a silly way for a boat builder to save a few bucks at the risk of a tarnished reputation. They did similar cost-cutting things in other areas, but seacocks is such a risky place to pinch pennies.
The other seacock in the photo is for an after-market generator (bronze, not brass) which can’t really be shared with the A/C system (don’t want to risk reverse flow in a/c system due to generator pump suction).
I’m interested in hearing how others may have dealt with this particular thruhull, valve and strainer combination. The strainer is small but seems to work Ok. It does lack a sight glass so must open to see if it contains any debris. The inline valve is inferior and clearly needs to go.
Am wondering if others replaced both strainer and valve or just replaced the valve. I looked into Groco valves, but they discourage the use of an inline valve as a seacock.

We hauled out & replaced all of the factory valves (Not the thru-hulls as they seems of decent quality). We have individual thru hull/valves for AC, watermaker, engine and saltwater wash down pump. Here's two photos. If you haul out, I suggest you also replace the head valves. Both of our jammed open.   |

Thanks fior the info and photos Tafika.
I’m guessing that you have modified your engine raw water intake to function as an emergency bulge pump also? Nice idea. I can’t do the same as my engine raw water inlet is in the saildrive... but I could probably do something similar with the generator raw water inlet.
Thanks again!
Thomas
