Hello again guys,
so here is an update report on my leaky Raritan
joker valve (duckbill) connection (please see what I did, that did not work
, and all your much appreciated earlier comments).
As a last ditch attempt I very carefully cleaned the connecting parts
(no minute cracks in the plastic and the joker valve is new and perfect shape). I then mounted a new fabricated RF steel
backing plate covering the outflow side connection and added large washers on the bolts on the toilet side. Tightening ever so slightly with quarter turns in turn on each bolt, starting from finger tight. Observed dripping via mirror, slowing but never stopping, and the increasing again when tightening more. Uhhh, no cigar!
Went home for a good think, and enjoyed a snifter of 12 year old whiskey
Next day with nothing to loose I carefully applied liberal amounts of Sikaflex on all connecting surfaces! Tightened the bolts only finger tight, taking extreme care to have equal tightening on both bolts, of course with the rf steel
backing plate in place! I then let that sit and cure for 5-6 days. Tried the pump
again, and lo and behold! Only the tiniest of drip showed up! I now tightened both bolts in turn, 45 degrees at a time, a total of 3/4 turns, until no discernible drips showed.
I have since tried pumping the toilet several times during the day and STILL NO MORE DRIPPING!
It seems that the RF steel backing plate plus the sikaflex actually did it!
Well as with all boat repairs
, I really do not trust this until some weeks has gone by. Time will tell.
I actually had one more idea to test and that would have been gluing the connections and joker valve together with TEC7, a builders glue, flexible and applicable under water
. Hope i will not have to.
Hoping this might help someone else at roads end like me!
NB picture shows backing plate, but the plastic connecting plate is OLD not the one mounted!
