V34 LEAKING SHOWER TRAY

TRIPTYCH'S REFIT CONTINUED:

SHOWER TRAY DRAIN LEAKS

With all the important stuff done, and most of the elective work too, it's time to look at the other issues. One job in particular is the shower tray drain which has a rubberised plug fitting connecting to a hose and pump, and thence overboard. Sadly, the rubber has perished and no longer seals the hole and thus bypasses the hose and leaks into the bilge and neighbouring woodwork.

With showers ashore at marinas it wasn't high on our agenda but it's something I'd like to crack just the same. However, before I do, I'd like to know some more about the local anatomy. I'm afraid, without this knowledge, if I pull out the rubber drain connector it will come off the hose which will be lost and inaccessible, leading to removal of panels and rebuilds. Is there a non-destructive solution?

Triptych is a 1988 build so certain items reach their sell by date, this is one of them; sadly no photo.

Many thanks

Don

Re: V34 LEAKING SHOWER TRAY

Hi Don,
Not had any experience of the shower leaking in Anitra's case. The shower hasn't been used since buying her 4 years ago. I am familiar with the plumbing/pump arrangements, but not in respect of how to go about getting at the underside of the shower tray/basin area. A bit of open heart surgery required me thinks!
Keep us posted.
Thanks.
Charlie.

Thanks, Charlie.
I'll be on the boat during the week, armed with camera to add a few photos. With a bit of luck I might be able to get an endoscope into that area non destructively and get some images from that, too.

Re: V34 LEAKING SHOWER TRAY

Hi Don
I too have had the tray leaking into the bilge. We find the shower really good to use and it helps keep the heads clean and fresh. I think mine is leaking because it floods over the top of the tray which is quite shallow and does not always keep up with the pump's flow.
Also the keel stepped mast always drips into the bilge in heavy rain. I am trying to resolve that by improving the mast collar but not having much success.

Re: V34 LEAKING SHOWER TRAY

Hi Alan,

I replaced the mast collar on Anitra just over 2 years ago when I was working on the mast.
The original was pretty much perfect, but I replaced it with another hypalon constructed collar supplied by 'A2 Rigging' (Falmouth from memory).

I suspected that most of the rain water was coming down the mast and into the bilge. This continues to be the case.

I thoroughly cleaned and painted the immediate area in and around the support for the mast foot as can be seen in the photo below.

I'm not 100% sure if the hose in the picture is the hose that comes from the shower basin, but this looks very possible as the sump pump is located in the seat base/locker to the port side of the mast.

Re: V34 LEAKING SHOWER TRAY

Thank you everyone. The leak hunt continues and we have had plenty of wet weather recently to challenge the suspect area.

Charlie, I note that the wood panel just forward of the mast seems to have some water stains like ourselves. In our case there is a slight void underneath that forms a kind of tray where water gathers. I can't get the endoscope in there but when my wife tried drying the area out with the hairdryer I spotted a lot of flickering underneath the woodwork due to water in the slipstream. Some kitchen roll proved the point. This seems to be collecting on the subfloor level of the cabin sole and has left water stains on the wood work. Is it coming from above, trickling down behind the paneling, and from where? It is gathering in the centreline and so is possibly leaking from somewhere above, again in the centreline as the camber of the coachroof would probably shed water elsewhere.

The blue hose beside the mast base in my case is the freshwater supply to the washbasin in the heads.

When I was down at the boat a few weeks ago, I covered over the area in front of the mast with a tarpaulin, weighted down with rope coils and the inflatable dinghy and checked it out on my next visit. It was still slightly damp down but there was no water so I revised the cover and left some telltale kitchen roll under the tarpaulin. Since then the weather has done its worst and we are going down again tomorrow.

I'm hoping that everything has stayed dry and I'll challenge the area with some plasticine puddles and food dye. The staysail traveler is my chief suspect but there are other areas that need attention as well. So far the two deck vents seem to be blameless and the metal collar for the mast at the coachroof seems well bedded but we'll check that too. As for the hole through the coachroof for the mast, that seems to be well sealed and the gaiter is sound but I'll be leaving some kitchen roll tell tales there too. There is water coming down the mast but I think it's coming down inside it, bypassing the gaiter.

This saga is far from over but we should find out some more tomorrow.

More rain on Thursday ready for the next phase of testing but somewhere along the line I'll need a dry spell for repairs.

Best wishes

Don

Re: V34 LEAKING SHOWER TRAY

I was on the boat on Wednesday this week and did some more testing, this time with food dye in three areas. I squirted 1ml of yellow food dye into one of the halyard openings just above head height and before I went home it had appeared at the base of the mast. See below:

There is a drain hole visible on the starboard side of the mast and probably to port as well though I can't see that side as easily. I think that proves water can bypass a well-fitted gaiter and get into the boat. Presumably it's getting in higher up through various slots for halyards, etc. and trickling down. One option may be to re-berth the boat, bows to weather for the winter to see if it reduces that leak or not.

I removed the cover from the suspect area on deck.

I then placed some red dye at the forward end of the bronze? mast collar on the coachroof to see if it was still fully bonded to the coachroof and also some blue dye at the top of the camber on the staysail traveler and contained them there in plasticine dams for an hour or so before I hosed all residual dye off the boat. There may be something to report after the next visit. In the meantime the suspect area has been left uncovered.
