Are there any traps available for marine sinks? My existing setup drains two head and galley sinks into gray water tanks (along with two shower drains). The sink levels are nearly at the waterline, thus it's impractical to run them directly overboard.
We use the boat recreationally, so there's sometimes enough 'down time' to allow the gray water tanks to get a stink going. The result is a musty smell coming up from the sink drains. This was made worse last week by discovering one of the gray water tanks had overflowed due to a failed float switch (typical Rule float switch unit).
It seems like a trap would be a relatively simple fix, in that it'd provide a water trap to block the stink. Although, with Whale gulper pumps emptying the sumps I suppose there's a risk they'd get pulled dry. The gray water sumps aren't vented. I'm thinking that there should be enough available air from the shower drains to avoid added traps being pulled dry.
