Stinking heads, anyway to prevent this

[dsbentley]

Hello from St Croix, Hurricane Omar did quite a number on the boats down here, over 40 boats sunk or destroyed! The Parrothead survived w/o a scratch thanks to the great marina she is located in!fficeffice" />>>

Onto my problem. I have two heads with Skipper toliets that work great. They use seawater to flush and I can either go direct to the ocean when off shore or through my Raritan treatment boxes. The slip I am moored to is at the end of the marina and there is no outlet or circulation of the seawater so I am told the water I am using to flush the heads with is very smelly to begin with and when I flush the heads at the dock I get a very bad odor. I was told I could take a gallon of vinegar and flush with that to help kill the smell. I was also told I could switch on of the heads to a fresh water flushing Raritan head and that would never smell but would use my onboard fresh water to flush.>>

The short answer: buy this book:

Peggy Hall: Get Rid of Boat Odors

It was incredibly helpful to me.

It sounds like a fresh-water flush would work.

Before you install any plumbing, check your present hoses. On my boat, the sink drain and the head intake share the same through-hull, with a T connection. For an (occasional) fresh-water flush, I simply close the through-hull and fill the (higher) sink basin with fresh water. Then I suck it into the head.

ever try those big breath mints.

The pump on a manual head usually has a plunger that serves double duty - one side evacuates the waste, the other side draws in the flush water. It is inadvisable to connect a pump like that to a potable water system.
