Trapped water under shower pan

[prroots]

Hi:
We have a relatively new-to-us Beneteau 411. We have evidence that the void under the forward head shower pan contains some water and that water is wicking between the grid and bulkhead into the forward stateroom. It's a small quantity of water but it's sufficient to cause the wood bulkhead to stain.There does not seem to be any limber holes to allow this water to reach the sump. We did die some water red and fill the shower pan. No evidence of the die appeared elsewhere which suggests the shower drain piping is tight. Has anyone experienced this problem and if so, how was it solved.

Nope, it's too much for that. We took about 4 sauce pans of water out of there with a small hand pump

If the pump fails or fails to pump faster than the input from shower it will fill and overflow. Or the discharge thru hull siphons back when healed .Usually a simple answer. rarely is it spiritual or magic. Check to see if salt or fresh.

Thanks. Unfortunately, neither suggestion applies in our case since the shower pan has never overflowed nor has water ever been siphoned back from hull fitting. In fact, the level of water in pan has never been more than a fraction of an inch while taking a shower. We keep it dry when underway so it would become immediately apparent if water ever appeared. As mentioned, we died water red and placed a few gallons of red water in the pan to be sure that the drain fitting and associated plumbing was leak tight. No red water showed up anywhere else even after using the sump pump to pump it overboard. Tomorrow we will seal the drain holes in anchor locker and fill it with died water since it shares a bulkhead with the head and a leak there would cause water to drain to the void beneath the pan. The water has a very slight salt taste; more like brackish. The one thing we can't be sure of is how long this water has existed under the pan since the boat is relatively new to us. We've now pumped most of it out and will monitor it to see if the level rises. Sure is a nuisance to say the least!

Some friends have a 36.7 that collected water under the cabin sole. It might be a Beneteau feature.
