Stus-List Re: Water back flowing through the head - rebuild vs replace
I just rebuilt one of these from a rebuild kit that was in a locker for 4 years on a dock in Coos Bay in the middle of a trip from Seattle to SF. If you have the time and stomach, rebuild it. Don't leave any components untouched. If there is a black liner that looks broken inside the main pump housing, use heavy chemicals and a wooden stick to break that down and flush it all out. All of the plastic should be white. Use good lube when reinstalling orings and seals. Be meticulous. Your crew and your pride will ask you why you hadn't done it sooner.

Stus-List Water back flowing through the head - rebuild vs replace
Ditto Rob's comment. I was a boat repair guy for 15 years. If the issue is in the pump assembly, replace the entire pump assembly! The assembly is usually only a few bucks more than the rebuild kit. It was ALWAYS cheaper for my clients. However, several still wanted me to put in a repair kit. Do the math. 0.5 hours for me to change a pump assembly. 1.0-1.5 hours to remove pump assembly, install rebuild kit, re-install rebuilt pump assembly. Then there's the possibility that the pump cylinder is scored, the non-replaceable valve sealing surfaces are scratched or gouged or some other issue with the thing that may cause the rebuild to fail. -- Dennis C.

Thanks Rob may do that and then cannibalized the old one for parts From: Robert Abbott via CnC-List Sent: August-30-22 10:02 AM To: Stus-List Cc: strig...@eastlink.ca; Robert Abbott Subject: Stus-List Re: Water back flowing through the head Rod Had the same issue a few years back with my Jabsco marine toilet...went to the Binnacle to get kit to repairthey talked me into a new pump instead...almost the same price and a lot less work from taking the old one apart, installing new parts and putting back together.

If no overboard discharge, If black water it’s the joker valve, if sea water the flapper. Mine does both under the right conditions. I close the raw water intake when under way, and change the joker valve every season, PLUS keeping the holding tank pumped out.

I clean/replace the joker valve routinely. I keep a couple spares on board. You can usually clean it by soaking it in vinegar overnight. -- Dennis C.
