I have a Catalina 390, 2002 with a Raritan SeaEra Toilet that pulls sea water verses pressurized fresh water. We mainly sail in the northern half of the Chesapeake Bay. My issue is the holding tank which I believe holds 20 gallons, fills quickly. Fills within 24 hours with only 2 adults. I lowered a snake to check if I had accumulated debris in the bottom of the tank. It was clean. The vents are unobstructed. How can I regulate the amount of raw water draw into the head or is there another issue to consider. I did try closing the thru hull valve and pour fresh water into the toilet but it seemed to stain the pump. Also I close the valve when not in use and definately when away from boat. I would think we should get a weekend use without needing to pump out.
Thank you,
Wes
