[Amel Yacht Owners] Salt water intrusion on forward head


amelforme
 

Yep, this can happen if you have a lot of water on deck. The SM 53 came from Amel with a  rubber flapper assembly that would line up with the chain and keep a good percentage of the water from coming into the chain locker. Many have perished and are gone. I like to use GREAT STUFF that one can get from any big box home improvement store in the USA. Do a web search. For our friends further afield, it is an expanding foam in an aerosol can that is used to fill cracks and voids in home construction and repair projects that has different names in foreign markets.. Spray the foam liberally around the anchor chain hawse hole. Let it dry and it stops 99% of the water from coming in. Just using the anchor/moving the chain causes it to crumble into dust and disperse which could aggravate some more eco minded folks.

 

One way valves are sometimes problematic and more so when hair and soap scum can be expected.

 

Have fun with your Amel, Joel

When sailing in rough weather with the wind in from starboard, the water that find its way in through the chain locker and then going down to the bilge. Some of that goes back into the forward head shower drain. Is it something like a one way valve missing? The hose going from the shower are connected directly with the anchor locker drain by a y connection only. We are thinking of installing a one way valve. are we alone experience this?

We have a piece of foam we use to plug the chain hawse hole. We just sort of stuff it in. I tend to forget about it when anchoring again and we find it later somewhere on the deck. It is not pretty but it works. I like Joel’s idea of Great Stuff. We have some aboard and will give it a try.

 

 

With best regards,

I really doubt you will find a check valve that will allow the shower dump to drain by gravity and yet prevent water from backing up.

Yes, water gets into the shower sump. Happens to us under the conditions described. So what? It's not ever going to overflow the shower pan into the cabin. If you are heeled over so far that the water is up out of the sump and around the toilet maybe it is time to reef?

Many boats have shower sumps that ALWAYS have residual water in them.

Hi Joel,

I hesitate to even write this, since your knowledge of Amels dwarfs mine.

That said,I always thought that the chain locker drained via the white hose all the way to the bilge. I guess I’m wrong (not the first time)?

We too get a lot of water in the bilge by the forward head, but I always though it was from our bow thruster seals. By the way, if you have a lot of water in that bilge, it can also slosh over into the area below the closet, as well as forward under the optional freezer. Be sure to clean these out to prevent smells.

The chain locker, air conditioning condensate, and the head sink and shower all join to the one hose that has the shut off valve at the saloon side of the water tight bulkhead. If you have water coming in the anchor hawse, it can detour into the shower sump on a starboard tack. 
If you have water from a bow thruster leak migrating to the area under the freezer against the saloon forward bulkhead, you have some serious problems

It may not be a real big deal, but in very rough conditions with tons of green water over the deck, we have overflowed the shower pan. It sounds like the check valve would not be a good solution, but I like Joel's spray in foam idea.

In the "more than one way to skin a cat" department, we cut off a 2-3" piece of a Swimming Noodle, slit it down the side so it goes around the chain and stuff it into the hawse hole. The pink noodles work best :-)  

Btw, on the Santorins the chain locker drains directly into the shower sump. Great design as it lets you know when your chain locker is getting too dirty and it's time to send your grandson down with a hose and brush.

Sorry, I did not sign my comments. Aletes is still with me (and my co-owenr, Mike). And yes, our bow thruster seals are pretty leaky in heavy seas.

I use a small nerf ball that I stuff around the chain in the hawsepipe.  It stops all but a little water from getting in.  Get a few extras as they deteriorate in the sun after a year or so.

Stephen I agree we have several times had conditions when water slushing around in the forward head. I think the idea with the spraycan sounds good. Asume it,s just normal PU Foam on spray can, have to be carefull when applying as it is very sticky. But of course the anchor and chain will rip it lose from the pipe. Last time we just squeezed in a pice of foam in the shower drain, also an easy and quick solution. My wife was air born for a while in the forward head when beating up from Cape Hatteras to Cape Henry in a god blow with current with us when she squeezed in a pice with foam in the shower drain.

We solved this problem by putting in a plumbing valve in the drain from the shower, moving the copper T connector further aft and rerouting the anchor drain to there.
The picture is better than my description...
