I had salt crystals around the hose inlet on main raw water seacock so cleaned this off and it came right back so clearly a weep of salt water was getting through. I checked the hose clips and they were not very tight so gave them a little tweak. A slight cracking sound and drip of water means I have to replace the spigot/hosetail. I understand Jeanneau have an issue with brass fittings dissolving so need to do urgently. The flats on the spigot look OK and the ball valve is working so am I likely to get this off and simply replace this without hauling out? Has anyone had the same problem.

A few more details would be good, e.g. suspected age of seacocks and through hulls. It isn't really just a Jeanneau 'thing' all brass through hulls and seacocks need replacing every 3 to 8 years when used in salt water, high quality bronze lasts much longer and is more expensive, the new polymer fittings are supposed to be good, but none of them are 30 years old yet .... time will tell. Your options are limited, if just replacing the seacock, you could find a tidal area with a wall and tie up , or anchor off and dry out on a nice soft sandy seabed and do the replacement over a tide. you could look at www.seabung.com, and have a go with that, they are handy to have aboard for through hull failiers. You could probably get a cheap lift if you get the last lift of the day, held in slings over night, and first launch the following morning, and work into the evening . you could remove the hose tail, clean it, is it going a pink colour? if so, hit it hard with a hammer and it will probably shatter as it will be brittle, ..... hitting it hard and breaking it will stop it spoiling your fun at a later date, and perhaps confirm the condition of your brass bits. on a brighter note, the crunching sound you heard might just be salt getting crushed. I would look closely at the age and quantity of the below waterline fittings, if one is 'on its way' then others may also soon need replacement, The through hulls seem to last longer than the valves ...... but if in doubt, haul out, open the wallet and replace the lot, it may seem expensive, but better than arriving at the boat one day finding it full to the brim in sea water which would be costly to say the least! Good luck CB |

Just to verify. are you referring to Bronze not brass? Brass is a no no on saltwater boats. the zinc in the metal deteriorates fairly quickly.
did/does Jeanneau still use the as underwater fittings?

By brass I was referring to was DZR which is a brass, most French boats are now fitted with this from new, life expectancy 5 years, so lasts for the warranty period. DZR brass is the 'C352 brass' with about 30% zinc, 61-63% copper, 1.7-2.8% lead, and 0.02-0.15% arsenic, but the zinc slowly disappears leaving a pink colour and a rather brittle item that breaks just when you don't need it to, the tin in bronze gives it the edge (and the price).

After leaving overnight there was a pool of water in the morning but no more dripping. The joint appears to be dry now. I looked at the spigot through the pipe and it looks fine ie. it's all there no bits missing or dissolving. It may well have been salt crystals I heard crunch bit it did then leak for a while whereas before it just had a frill of salt crystals. So seems its sealed itself. When I lift it out for a clean I will remove and clean everything and replace if its dodgy. I am not sure if its brass or bronze.
