410: shower drain water problem

[goldenananda]

we have a L410 S2 Owner's Edition. sometimes in the morning we find water in the shower with no idea how it might have gotten there

any ideas please?

[Stu Jackson]

Most shower sumps have a check vlave between the sump and the pump. Check the check vlave operation, sometimes they get clogged and don't work anymore.

Is it salt water or fresh water?

I think that Stu got it right.
The shower pump pushes waste water up hill to the outlet through-hull. There is a non-return ("joker") valve as part of the pump assembly, assuming you have the Whale Gulper pump fitted. This valve tries to prevent waste water in the outlet pipe from flowing backwards once the pump stops pumping. Contamination from hair and other matter frequently makes the valve leak and water will start to pool in the shower drain recess. New valves may reduce but not eliminate the problem. It's an annoying part of having showers down in catamaran hulls

You could try running some cleaner down the drain (not the commercial stuff), try baking soda & vinegar, then real hot water (all enviro friendly). Should clean out hair & the soap crud build up from any traps and flapper valves.

I would almost guarantee you will find the check valve isn't closing as a result of human hair.

Do not wash your hair in the shower plus I only use liquid soap, it is not greasy like cake soap.

From Transport Canada's Safe Boating Guide

Use Environmentally Friendly Cleaners
All-purpose cleanser
Mix 30 ml of baking soda or borax, 30 ml of tea tree essential oil, 125 ml of
vinegar, 15 ml of biodegradable dish soap and 2 litres of hot water. Spray on
the surfaces you plan to clean.

Chromium
Rub with baking soda. Rinse and polish with vinegar in hot water.

Deck and floor
Pour 250 ml of vinegar in 2 litres of water.

Drain
Pour 60 ml of baking soda in the drain, followed by 60 ml of vinegar. Let it
rest for 15 minutes, then pour in a full kettle of boiling water.

Mold
Add 60 ml of borax and 30 ml of vinegar to 500 ml of hot water. Spray the
mixture to eliminate germs.

Toilet
Pour 125 ml of baking soda and 125 ml of vinegar into the toilet bowl. The
foaming reaction cleans and deodorizes. Brush and flush.

Window and mirror
Mix 2 ml of liquid soap, 45 ml of vinegar and 500 ml of water in a spray
bottle. Use a cotton rag to clean and shine.

Wood (polish)
Mix 30 ml of edible linseed oil, 30 ml of vinegar and 60 ml of lemon
juice in a glass pitcher. Rub the solution into the wood with a soft rag until
it is clean. To store the solution, add a few drops of vitamin E from a
capsule and cover.

Passed for general info only.

Totally agree with the liquid soap it is significantly better.
