Probably a grey area depending on region and regulations
, but now that I am back living onboard at Subic Marina I am amazed at the stench from full grey water
being pumped out in the evenings.
Everybody uses the excellent shore side toilets, but all the new multis hold their shower
and Galley water
for a few days, then pump
out copious amounts that has not aged well!
Before my refit
, I had the same and the showers/ sinks would all pump
into holding tank
that with 5 onboard wold be full in about 6 days.
You could definately smell it!
So I decided to put Y-Valves in and divert to direct discharge.
Now, the small amount of "fresh" shower water
pumps quietly into the marina, with no stench at all.... I like it!
Another plus is that I moved the 2 Whale 320 pumps to the engine
room where I have a bildge pump manifold.
One of them now has a second 3/4" suction hose with a Y- valve that goes into my deep engine
down, it is a perfect wet vacumn.
Why hold grey water
for days, rather than direct discharge, if allowed?
