Sewer hose connection

Pretty new to this coach and I haven't seen any others close up to be able to figure this one out on my own so here goes. My sewer hose connection at the MH is so far toward the door of the compartment that it does not allow you to put the hose through the spin off cap in the floor. First question is, did the motor home come from the factory with some sort of 90 degree adapter that fits between the MH drain pipe and the sewer hose? Second question, if no fitting, how do you drain the waste that collects at the low spot in the hose by the connection? I cannot see where a standard 90 degree fitting would have room to install between the MH and hose.

The sewer hose coupling is on a swivel that allows it to turn to align with the hose coupling. Put small amount of pressure on it by grabbing it with both hands and I am sure it will swivel down to align.

Hi Greg,
I do not know your specific coach. If you able to visit a RV parts store, there are many different angle adapters and connections one can try. You could also try the Camping World or RV Upgrades web site. The connection on the coach may also be able to be moved up/down/left/right.

You probably need the 45 degree adapter which I use. The clear version lets you see when the tank is clean.

OMG, thank you so much for the help, I've been trying to figure this out for two months, the fitting does indeed swivel and now everything makes sense.

The swivel makes up for poor design. John is right though, a 5" clear adapter will allow you to see when the water runs clean. The 5" straight piece just clears the bottom of the coach. A 4" one would be even better when the coach is really bellied down into the ground, but 5" seems to be the standard at Camping World.

BTW you are not alone in figuring the swivel out. Fortunately my impatience kicked in on the first day.....

WRV design of the sewer connection seems to me to be very workable. It keeps everthing up out the way from road debris and a possible damage.

I will comment on the clear adapter/elbow/whatever

Many folks ask "Why would you want to look at it" Trust me, don't look bad at all, It's just brown "Water" (Looks like muddy water) but it's sure nice to know when it's clear again.

I have a collection straight, 90 degree, 45 dergee, and a back flush adapter I have used exactly one time since my coach has a flusher built in and I got the wrong back flush adapter (Though I do have a way to use it, and may use it on the gray tanks)

The one time I used it was on a travel trailer.. I do not OWN a travel trailer
Home is where I park it!
