I am considering replacing both Jabsco heads in my DS43 with the more powerful (and better joker valves) of the Raritan Ph Superflush, but do not want to do so unless the Jabsco heads are mounted to the floor with lag screws and not bolts with washers and nuts below. Has anyone changed out a head in a DS43? Thanks for your help.
Yes. But only for the Jabsco Liteflush electric and that has the same footprint as the manual, albeit the fixing nuts are easier to get at than on the manual one.
Down here in the Ionian the Jabsco gets clogged up with calcium every couple of years or so. Having spent hours servicing both the electric and manual (in the forward heads) a friend who looks after around 100 charter boats told me just to throw away the old one and replace with a complete new unit. There is little difference in price. Unless of course you enjoying working in small confined spaces in 30c temperatures.
To prove the point he showed me a skip and the back of his workshop completely full of old toilets.
Thanks for the quick response to my question Alenka. If there are fastening nuts below the manual heads, I will not replace them. There is simply no practical way to access the nuts without cutting access ports to that area directly in front of the heads. I was hoping that they were secured with lag screws into the flooring through marine plywood which would have made replacement much easier. I do use the Raritan joker valves in lieu of the Jabsco joker valves and the Raritan usually get me two years, unlike the Jabsco that only get me six months to a year. Thanks again!
Great idea Malcom. I will give it a whirl next week if I can get up to the boat through the snow and freezing rain that is forecast forvHood Cznal, Washington where the boat is now moored in unseasonably cold weather🥶 Thanks!
Sleighride, I was in Bremerton today near the airport. Most roads are very clear. Even most parking lots are now clear. Had not heard of freezing rain weather for here in Puget Sound region. Another fellow was in Bellingham, snowing a bit, melting when it hit the ground. Marty
Thanks for all the responses! I am convinced that coach screws are the same thing as lag screws (screws into wood with no nuts for attachment at bottom end.) Thanks for weather update Marty. We leave for boat and Hood Canal tomorrow. I plan to order new Raritan replacement heads but will first confirm the coach screws as the attachments per Malcom’s suggestion.
