Based on this Jeanneau
Owner’s & Cruiser’s Forum comments & suggestions, I re-inspected the systems again. It looks as if I had two contributing factors.
The Vetus non-return pressure valve had stuck open & dumping salt
water directly into the under-bilge. I cleaned the value, ordered a new one for replacement and attached a 22’ long 5/16” ID water hose ($0.76/foot + clamps…pretty cheap
fix) to drain into the forward bilge pump
sump area. Why Jeanneau thought it was a good idea to dump salt
water into the under-bilge is beyond me. Had there been a general failure of the valve, the boat
could have flooded. For an additional $25.00, this could have been avoided if Jeanneau have run this hose overboard
or directly into the bilge pump
The second problem was harder to find. I saw a rivulet of water exiting the exhaust hose where it enters the water muffler
. While tightening the clamps, I noticed the entire male fitting was loose. I removed the hose clamps, hose and fitting (easily removed by hand…no tools). The threads looked to be sealed with standard plumber’s putty. There were no cuts, splits or gouges on the “O” ring. I inspected the fitting and receiver box for any crack….none. After cleaning
the male & female threads & an “O” ring, I applied a vibration resistant Rectorseal 4-oz. Tru-Blu Pipe Thread Sealant
to the male and female threads. I applied a generous amount of silicon grease to the “O” ring and “O” ring seating area and reinstalled the fittings & hose. No leaks
The under-bilge did take a few sailing trip to finally empty, but it’s basically dry again.
Thank for everyone’s help!
