Seneca Sewer Hose Advice

[Mwade]

Got busy today and fixed the sewer hose problem. I removed the large black sewer pipe going through the compartment floor. Then I removed the small port for the water hose that is located directly in front of the black water valve. I then cut a 6 in. Hole in place of the 4 in. Hole. I then installed the black sewer pipe in the new hole. I then made a larger plastic plate with a 4 in. hole, and installed the smaller water hose fitting. All I did to be able to fit the hose end connections into the black sewer pipe was grind the large tabs small enoughf so the fitting would fit nicely into the sewer pipe. This makes for a straight shot from the black water valve to to the floor of the compartment. I also used a 45* elbow connected to the black water valve.

Having trouble sending all pics at same time!

Did the same as Mr. Oz and it works great. Blueline is the way to go.

I hear they eliminated the swing pipe and simplified the assembly on the 2016's and also added a macerator.

I saw the the 2016s are equipped with the macerator. I'll be curious as to how that works out; seems overly complicated to me. I wonder why Jayco engineering didn't just simplify the current gravity dump system. I believe in the KISS principle.

[Mwade]

Yes, I agree, keep it simple as you can. As you can see from the above problem with the Jayco factory installation of the swivel pipe. The Jayco design engineers were asleep at the wheel. What were they thinking? It is like they just gave up half way through the project. Another thing I can't figure out is why the fresh water system is located in the same compartment as the sewer! These two systems should be located far apart from one another.

I did the same as Mr Oz and what a slick setup.

Mwade, Jayco's implementation is the same as on higher end class A coaches. It's more sanitary than my Tiffin was in that I never have to detach the sewer hose inside the wet bay…the messy end is in the swivel pipe. Once the 45 clear pipe and proper fittings are installed you're done with the mess.

i ended up (for now) just adding an end onto the plain hose end that is in the swivel pipe and that attaches onto an extension or the 90 going into the ground

I finally got around to reworking the sewer connections

[RoWest]

My 2014 Seneca black ABS extension with the 90 degree fitting will not clear the compartment door when closed so the sewer hose runs forward or backward parallel to the door. And like your old configuration the sewer hose runs diagonally in the compartment.

I cannot figure out how to get a photo in here. It's in my album if you want to see how I set it up.

We've got a 2016 37FS. It has a thin in diameter, 2 inch grey hose hooked to a macerator. Have never used the macerator, but use the macerator hose to empty the grey water every other day. I mounted a black/grey sewer hose container pipe on the back of the stabilizer jack frames and it sits right below the drain hole in the compartment going up to where the black and grey Rhino hose gets emptied, when emptying at a normal dump station.
