[C320-list] Holding tank filter

Sat Jun 27 13:33:57 PDT 2009

Does anyone get the British mag, Yachting Monthly. They have a great article this month, testing where the smell comes from and how to get rid of it. Apparently much of it comes from the pump. Particles remain in the pump in small areas that do not flush clean, and they react with the air to create the  H2S. The solution is to leave water in the pump, either fresh or seawater gives the same result. Contrary to popular belief they proved that sea water doesn't decompose and cause the H2S smell, so no need to leave fresh water in the system, but just don't leave it dry. After dry pumping always pull some water back into the pump before leaving the boat for any length of time.

I'm going to try this.

Even easier, when I had my 320 all I did was have 12oz beer-type plastic cup in the head and would simply use that to fill the bowl as appropriate...others have installed direct fresh water via Y valves and the like but I enjoyed the simplicity of mine... :)

I owned it for 12 years and never had a smell problem, even with the same black hoses..

Orlando I've seen many other older boats hook a Y valve to the Head sink drain. So when you needed water in the bowl you run water into the sink which the Y valve would be diverted to the sink and used and the water to flush. 

There was nearly no smell on the boats I've been on with that set up

Also, if you use fresh water to flush instead of salt water, it will prevent most of the smell problems--hose replacement notwithstanding

So everyone else has the problem with the smell?

My surveyor told me that the black rubber hose from the head to the tank is the cause. So its on my list to replace the black rubber hose with a white coated synthetic hose. 

Anyone else have this problem and remedy with the fix I mentioned?

No, so far we have not had any sign of an odor on my MKII. I don't  
know if they changed the vent locaton or if just being newish helps.

The tank monitor is really nice since it does both fresh water tanks  
as well as the holding tank. I have found I was refilling and pumping  
out way more than needed as a precaution.
