Acceptable methods of securing the device include—
(1) Closing each valve leading to an overboard discharge and removing the handle;

I don't have a Y valve. Black water goes directly into the holding tank. The tank can be emptied by pump-out or by a macerator when in legal waters.

The macerator is run by a key activated switch, and only I know where the key is hidden. I believe this meets the requirements above.

Pretty sure the key meets generic requirements...like USCG coastal....

but some requirements like those mentioned earlier about the Great Lakes and as I mentioned in another post, I have heard of other localities that have tougher requirements.

Clemson University ....


A fecal coliform test is used to determine whether water has been contaminated with fecal matter. The presence of fecal coliform indicates the possible presence of organisms that can cause illness. The test can be performed relatively quickly and easily. The EPA has set acceptable limits for fecal coliform in water based upon the use of the water. For example, drinking water cannot contain any fecal coliform but water for swimming may contain up to 400 fecal coliform colonies/ 100 ml.

What is fecal coliform? Why is it important? : Extension : Clemson University : South Carolina


The Raritan Electroscan returns water at less than 0-20 coliform /100 ml

About 1/20 the the swimming maximum standard.

You can't believe anything that comes out of Clemson University.

Reading this thread made me decide to add a keyed switch in addition to the breaker switch that currently starts my macerator pumpin. My macerator is on a 20 amp breaker and the spec says it draws 16 amps so I figure I need a key switch rated at 20 amps but am having a heck of a time finding a 2 position key switch that I can flush mount in my panel rated at 20 amps.

Any tips?

MY simple solution is a Y ( a Y not a Y valve) just under the deck fitting.

Tank drain on one side , maceriator on the other.

By removing the on deck flush cap the macerator can not suck the goo.

No big deal, falling in a 1 1/2 hole , and its ready for use whenever the poop pump boat is handy.

No smell.

When the maceriator dies again , I will get rid of the Y and just keep a manual 1 1/2 inch Edson aboard , emergency bilge pump, emergency poop pump.

The ball style connections are about $10. at Tractor supply , switching from bilge to poop should be almost instant.

You can install a 20 amp relay. Use the key switch to engage the relay and use a normally open contact on the relay to run to the breaker.
