Sewer Hoses

Does anyone use a "Y" connector on their sewer hoses?

Not tested in real camping yet.  I am worrying bounced stone off the road puncture the hose .

I would be concerned about lingering debris on the corrogated tubing.

Yeah, I see that as an undesirable result as well.  Typically, one would dump the black, then dump the grey, to wash out the residual black, with the slightly less nasty grey water.  With the pictured setup, the black leg of the Y would never get completely rinsed out, unless you removed it.  And, if you remove it to rinse, you have not saved yourself much trouble. 

However, I'm thinking in the context of camping without a sewer connection.  If you are parked for longer periods of time, and have a sewer connection, this setup would simplify your dumping to simply pulling levers.  You could worry about rinsing everything when you pack up and leave.

@littlelulu I’d worry about a connection fail if I understand your set up to be used while towing-I don’t think the separate parts are up to the rigors of bounce and jostling of going down the road. don’t know if you’ve read this thread, but it describes a few mods to create a combined sewer outlet for the black and gray tanks.

True.  You can rinse the corrugated tubing more thoroughly by flushing when hooked up to city water and a sewer line.  We have the separate outputs.  When we camp with a sewer connection, we connect the hose to the gray tank.  We let the tanks fill before dumping.

I had the two to one connector mod done and couldn’t be happier with it! Good luck!

Good comments.  I would connect the Y to the black tank and have extension  tubing on the grey tank.  My thinking is with the Y directly connected to the black,  grey water would rinse out the Y connection.  (Hooking up drain hose and Y opposite of the picture provided.)
To me it is just a bother to have to switch from black to grey when emptying the tanks
Granted it's not much of a big deal.
I wonder why the T@B Iis not constructed with one drain as most RVs/trailers are.
Do people really travel with drain hoses attached?  I can't imagine the hosing would survive that.
Anyway, thanks for the feedback.

homebody@heart:  who did the mod for you?

The new T@bs finally have a single hose connection.  I forget what model year it was introduced, either 2017 or 2018.

2018 now have the single outlet as standard.

@littlelulu @Dalehelman helped me with mine. I think the 2018’s have them joined now.
