Peggy - I have looked all over your site, including your Reference Library, but I cannot find the article "Intake Odor Cure" that you reference in numerous responses to people with raw water head intake odor problems. Could you please point me to it via a link? I have come to the conclusion on my boat (1998 Hunter 310) that the only permanant cure for this problem is to stop using raw water, and just use fresh water for head flushing. This is especially true for folks like me in warmer climates (Clear Lake, TX) where "city" water is readily avalable dockside year around. I know I could rig something up where I could tie the head intake line into the sink discharge line with a y-valve or some similar gizmo, and then run water into the sink and flush it through the head from there, but that sounds like a real pain to me and would be about as easy to explain to guests as how to use the zero-gravity toilet on the Space Shuttle. Idealy, I would like to have the option of using fresh water most of the time, but be able to switch to raw water if out cruising and fresh water supplies became low. Also, I could get raw water from the sink discharge thru-hull and remove the present head intake thru-hull seacock, which on the 98 310 was mounted in the middle of the floor of the head compartment with a sign on it that reads "Stub Your Toe Here." Since I have a presurized water system, I don't know of a way to get water out of the water tank without somehow going through this system. Can you offer any clues? Also, is there a risk of contamination of the boat's fresh water with backflow waste from the bowl of the MSD? It seems to me an easier solution would be to install a second fresh water tank (perhaps the bladder-type) somewhere on the boat that is dedicated for head intake only, but then the question arises as to how to fill it without running a garden hose down through the hatch every time it needs filling. I would guess fresh-water flushing would not only eliminate the intake problem, but would also significantly reduce hose permeation odor and holding-tank related odors, especially for boaters like me that subscribe to the simple rule "No.1 head to the head, No.2 head up the dock." Maybe all these answers are in the article, and I look forward to reading it. Thanks for your help in Advance! Mike Kelton S/V Bwana Wind

Easy to find
Mike try this way to get to it is through the forum archives, search for intake on Peggy's forum

I'm not sure when/how/why the title was changed to "Intake Water Odors"...but I WILL refrain from asking why, if you browsed the library, it never occurred to you that "Intake water odors" and "intake odor cure" MIGHT cover the same subject... There is NO way to connect ANY manual toilet to the onboard fresh water system without risk of contaminating the fresh water supply, damaging the toilet, or both. Only electric toilets that are designed to use pressurized water can be safely connected to the onboard fresh water system. Your only options for flushing with fresh water are, 1) close the seacock and pour water in from the sink, or 2) install a separate flush water tank, 3) a new head designed to use pressurized water. However, intake odor problems only occur when sea water is left standing in the intake to stagnate. The cure in the article solves that problem by providing a way to flush the system out with fresh water before closing up the boat.

Good reading
As a typical guy who doesn't bother to follow the instructions, I've learned most of what little I know about heads from Peggie's sage replies. Only recently did I go through her library for a complete tutorial, and I recommend it highly.
