So we solved the smell finally but I noticed something still wasn’t quite right with our Raritan PHII head. It became immediately clear when I added some of the smelly blue tank chemical to the bowl and pumped. The blue stuff was coming out the TOP holes in the bowl…. illustrating that we were still getting waste water mixing with the salt water intake.
WHAT? No way “waste” water can get in – we’ve replaced the joker valve twice now. Both of us were beyond frustrated and I called Raritan Tech Support in complete desperation. (Raritan Tech Support 954-525-0378, Matt – or maybe Mack, didn’t get his name clearly). Matt was a miracle worker. He listened to the situation and said …
“There’s only ONE place in the entire PHII configuration where waste water and intake water can touch. And that’s the O Ring inside the pump housing. Have you changed the O Ring?”
That sent us digging in our spare parts for a new O Ring. We found a used one fairly quickly, but that won’t do. Finally we found a new one. David began dismantling the pump once again and pulled out the offending O Ring. It didn’t look bad at all, in fact it might look better than the new one. Oh dear …
But off with the old and in with the new – which would barely fit inside the pump housing! The old one slid out with plenty of clearance … maybe, just maybe. David lubed up the new O Ring with PTFE heavy duty grease and finally eased the O Ring back into the housing. After putting it all back together, IT WORKED!
Being the pessimist I am (actually I’m NOT at all, but this head project was getting on both of our last nerves!), as soon as David left the boat, I poured more blue chemical crap in the bowl and flushed. NO mixing! No blue water, only clear salt water!
So hopefully this is the END of the END of this year’s head saga. At least we know everything is new … and we don’t remember changing that O Ring since we bought an entirely new pump in 2012, so I guess it is 4 years old and maybe we should have changed it sooner.
Just one more thing to check if you’re having trouble with your head. In retrospect, I wish I had poured the blue chemical into the bowl and pumped earlier, we would have immediately seen it coming out the bowl top and would have diagnosed the situation differently (with the help of Raritan Tech Support).
