I called Raritan and asked them this same quesiton and the guy wanted serial numbers....the tag has so much paint on it that I cannot get a number.
I have this Raritan Crown Head. I want to plumb it so that it will discharge into the TOP of a holding tank. The inlet of the holding tank will be about 18" higher than the discharge fitting on the head.
Thanks Bruce
I will try it and report back. I have purchased a kit and rebuilt this unit. One thing I noticed was that a plastic disc between the mascerator and the centrifugal impeller was missing.
Harry,
My B33 factory set up was about a 2" rise over 2' to a Lectrasan. The output of that went to a vented loop that was about 18" higher then down to the thru hull. I thought it worked pretty well.
This year I had to rip all that out & put in a holding tank as the Lectrasan is no longer legal in our waters. (friggin politicians!) I now have it plumbed straight fwd about 18" down thru 1 1/2" pvc & aft about 4 1/2' & then up to discharge into a holding tank. The fitting at the top of the tank is about the same height as the Crown discharge. The head now pumps much better than the previous set up.
I'm sure you're aware that with an 18" rise you are relying on the joker valve to prevent any backflow. Since that section will always be filled with waste, I think I would use pvc that is soft coupled with hose at each end. I think otherwise any run of hose would get permeated fairly quickly.

My thoughts exactly. Let us know how the test goes please, I am curious about the pumps force. The TP test will tell somewhat, but I think that the viscosity of solid waste would make it even more difficult to push than the TP alone.
Harry,
What are the three immutable rules of plumbing?
Hot's on the left.
Cold's on the right.
And . . .
Somethings don't run up hill.

In our neck of the woods we only have 2 rules about plumbing
Water (or whatever) don't run up hill
and
Payday is on Friday
I intend to run the test that Bruce tested a little later today or tomorrow and I will definately report back
Right now (or before I took a lunch break) I am cleaning and vacuuming and trying to get all of the fiberglass dust cleaned up......man! ! ! that crap gets everywhere.....even in my shorts! ! !
Harry,
and if you're a plumber, don't bite your fingernails.

Well the verdict is in......at least this Crown Head will pump up hill.
The attached pics show the discharge hose 21" above the "Joker Valve".
Just could not bring myself to throw perfectly good Brownies down the toilet so I tested with 2 slices of Bologna, one slice of bread smeared with a healthy helping of peanut butter (with nuts) and a fist full of toilet paper....all in one shot. Little Miss Raritian had no trouble digesting.....
I am really glad that I did this test because I could not believe just how much water this little puppy pumped.......my guess is about 10 gallons per minute. She sucked the bottom out of a 5 gallon pail in short order....better supersize the holding tank for the ladies.

Sure Bob.....no problem at all....but I do need to make sure that the head is working properly.....I'm gonna need it when I add up the final cost of this project or the first time I smack something with my new bright shiney props. Ya know what I mean?!?!?!?
as any carpenter will tell you....water will definitely run uphill. my rules of plumbing and water in general are...........if you want it to flow freely ...it wont. if you want it to be contained ....it will leak.
BTW harry...you were right about it being an electric problem on that no idle deal

Glad you found it but......don't blow the horn quite yet.....make a couple more trips before you consider it fixed.
But I can tell ya.....I have had many more electrical problems than fuel problems.
I remember one time when I put a new engine in my old Chaparell I must have smashed a wire that went from the starter solenoid to the coil.....the damn thing would run just fine until for some reason the damaged wire would move around and short to the engine block.....drove me crazy...(I know..short drive).......the most embarrasing was when it stalled in the middle of the Christmas parade on Fish River.
The way I found it was.....I went to the auto parts store and bought an electronic ignition system....when I removed the distributor and coil I found the wire......I repaired the wire and took all of the electronic stuff back for credit.
