Hi Everyone

I am installing a perminent head/holding tank system on our boat and have a question on the hose run from the holding tank to the Pump out/Waste fitting...the instructions say that it should be run directly above the holding tank but I am curious if I were to route it further away for easier access to hose clamps and neatness of installation.. will a longer run effect the ability of the pump out to well suck out everything?? I have plenty of sanitation hose to make the run.

The toilet is the Sealand 711-M28 Traveler

Thanks in advance!!
 
The sooner you get the pump out hose above the top of the holding tank the less residue will remain in the hose. If you will turn the hose directly up the side of the tank and get it above the level of the top of the tank the better it will pump out and the less residue will stay in the hose. If the hose runs straight out from the side of the tank with little or no elevation it will retain residue up to the point where it get's to be higher than the tank.

In short, turn the hose up and get it higher than the top of the tank as quickly as possible.

Don't even ask how I know this.

And keep it running uphill all the way. Any loops will collect sewage. Sewage that remains in sanitation hoses will cause them to stink eventually.
 
If it is in the budget and legal where you boat, you may want to ask Vic about an onboard sewage system. I have not met one person who installed one who later regretted it.

If it is not in the budget, I would recommend vents on both sides of the boat. A well vented holding tank will be less likely to smell.

I am not a fan of vent filters and tiny vent holes, but that is me. The vent hole on my Regal was about an inch in diameter. That enabled me to shove a garden hose in the tank and flush it while I pumped it. That made all the difference in the world clearing the tank of sludge.

I believe GeeBee installed a Camco Tornado (google it) in his boat to accomplish the flushing thing easier.

Good luck.
 
David, he can't connect his Marine Traveler to a treatment system. The Marine Traveler has no pump; it is a drop-down toilet like what is found on most RV's. The holding tank is actually part of the toilet - think of a square tank maybe 20" x 20" and about 8" tall, with a toilet bowl sitting on top of it, see picture:

Treatment systems require a marine toilet with a pump on the discharge side.

OOPS!!! [:-dunce]

Now I know. I have never seen a setup like that before. That's a great idea.
 
hose length isn't very important, a few feet wont' make a difference. as others mentioned, keep the run uphill so that the waste which remains in the hose when you disconnect the hose can flow back in the tank.
 
Thanks for the pointers as usual guys....tank is installed and was able to get the run up quickly and in a way to make it look pretty good....no issues pumping out...all in all happy with the set up.
