Peggie, last fall and this spring I wrote to you about installing a pre filter in our head intake hose. (We were having problems with grass, algae etc coming into the boat and lodging itself into the rim bowl of our PH11,,,and rotting),,,,,. Well. I just wanted to let you know...IT WORKS GREAT!... I had a pre-filter from an old water pump I used....it turns out the screen was not fine enough to catch most of the debris so I found a finer mesh and it works great...the cup and the mesh stop enough of the critters and the bowl smells....well non existent! I clean the screen about once a month so that's not bad....the head draws the same and the intake doesn't seam like its working overtime on the draw. Just a little thought for your repituar of tricks. thanks for your help. Rob

Another idea
Eliminate the raw-water intake altogether by keeping the valve shut and using only freshwater from the boat taps. That way you don't get bacteria build-up in the hose, which is what smells when you first start pumping. An unintended benefit is that you run the taps, which Peggie always recommends to keep things fresh. I put a gallon of water in a jug and leave it in the sink of the head for all to use.

Bill...you're doing it the hard way...
Why not just tee the head intake line intothe head sink drain line? Then all you have to do to flush the toilet is run water. Because the seacock is closed, the toilet will pull the water out of the sink. Better, yet...it's not even necessary to use water from the sink to flush every time....'cuz it's only when sea water sits in the system and stagnates for days that it stinks. So conserve your fresh water by flushing with sea water...then, after you close the seacocks in preparation to leave the boat, give it a final flush with clean water down the sink to rinse the sea water out the whole system.
