I just had my ORIGINAL manual Jabsco replaced with an electric sea water intake Raritan Sea Era head. I used to pump 8-10 strokes to assure that waste was making it all the way to the tank and not standing in the hoses. How long should I hold the electric switch for the same thing to occur? Thanks - I ABSOLUTELY follow your book!

me too
Good question - just installed same head but with fresh water flush. I am sure the answer to your question depends upon how long a run it is to your tank, i.e., how much hose has to be purged? Don

Don is right...
Good question...and one of the few that isn't answered in the manual. I've emailed Vic at Raritan to ask him for an estimate of the distance/second bowl contents can travel...one or the other of us will get back you on Monday. Keep in mind that it will be only an estimate...'cuz how straight the path is from the toilet to the tank does make a difference. Stand by for me or Vic...

Hose length
Peggy and Don: Checking the manual, looks like about 17 feet of 1-1/2" hose to the tank - give or take a little. Thanks for the advice and looking forward to the feedback from Raritan.

Jerry, how can you tell from the manual....
how far it is from the toilet to the tank on YOUR boat? Or are you looking at the manual for the boat, not the toilet?

Peggy: 356 Manual
I was looking in the 356 manual. I didn't take into account the vented loop in the discharge line. That probably adds 1 to 2 more feet. That would make the total pipe lengtht 18-20 feet. Thanks for all you help.

356 sanitary hose
Hi Jerry, 17 feet is the right length, we just replaced our hose-it permeated in just 3 years! but there's no vented loop in the discharge hose-are you talking about your new installation?

Discharge Hose
Hold the button in until the bowl has cleared, then 1 additional second for every foot of connecting hose between head and holding tank (that's why we recommend that the discharge hose be 10 feet or less - a standard 10 second flush of the toilet will move waste roughly 10 feet through a 1 1/2" hose). Seventeen feet, in my opinion, is WAY too long of a discharge hose...

Thanks to all!
Peggy and Vic: Thanks for the correct information. Until I looked in the Hunter manual, I would have guessed that the distance was no more than 10 feet and for the first two seasons had pumped about 8 to 10 times to "purge the line". I;m sure now that was only half enough. Before leaving the boat Sat, I held for 20 seconds for the KO to get to the tank. Looks like that was a good thing!

Vic's right...that IS WAY too far!
In fact, it's at least 3x the optimal distance of 6'...and twice the max distance any toilet can move bowl contents in the time anyone will actually spend flushing. But unfortunately, boat builders apparently give absolutely -0- thought to sanitation systems when they install 'em. If you're flushing only into the tank, why is there a vented loop in the head discharge line? You don't need it...and if you remove it, you can shorten the head discharge line by that many extra feet.

H356 sanitary line
good thought, Peggy, BUT! the 17 feet doesn't include a vented loop! the vented loop on my 356 is in the raw water supply line to the head. I never expected the huge run, either, I'm sure that's why the hose went so quickly. I've added a sink connection so I can flush with fresh water and CP after every weekend so I can be sure the hose is clean.

Wait a minute...
First you said, "I was looking in the 356 manual. I didn't take into account the vented loop in the discharge line..." Now you say there is no vented loop in the discharge line. So which is it??? The vented loop in the intake has nothing to do with head discharge...but if there is one--and if it's been the thru-hull and the pump, you're gonna need a solenoid valve to prevent damage to the intake impeller in your new toilet.

No loop in the discharge line
There is no loop shown in the 356 manual. That was an error on my part to discuss that. The 17 feet is what Hunter shows in the manual as a straight connection from the schematic. Sorry for the confusion on the vent. I have been using KO since new in spring 2003. We pump out every weekend so there is never waste standing in the tank over a week. I think with the original Jabsco, I was just dumping the KO in the hose - never getting to the tank during the week after pump-out. I also have calculated the volume of water in the just the hose and to clear it seems to take about 4 gallons! his has been a good education on this topic. If my hoses permeate, I think I will install a Lectrasan and by doing that, can eliminate the distance factor to within about 6 feet by putting the Lectrasan under the rear bed on the port side. That will also take out some time when coming back in every weekend.

sorry Peggy!
Jerry is the one talking about the vented loop in the discharge line-I'm (chuck) the one who just replaced my line and there's no vented loop-i have a vented loop in the raw water line, where it should be
