Which 5th wheel trailers have bathroom sinks that drain into black water tanks?

by Jackie
(Knoxville, TN, USA)

I read somewhere that some manufacturers plumb bathroom sinks and/or showers so that they drain into the black water tank. I am considering purchasing a pre-owned 5h wheel (2005 to 2009) and would certainly like to avoid any that have this feature. Could you tell me how to determine if the model I choose is plumbed in this way? Thanks for any help you can give.

ANSWER: Greetings Jackie thanks for submitting your question on our Ask An RV Question Page.

Yes there are a few RVs that are plumbed this way. I am not aware of any list that will tell you which RVs have this plumbing setup. I understand your concerns with having a shower, bathroom sink or kitchen sink draining into a black water tank. You could imagine if the black water tank gets overfilled what would be coming up the drain of the shower. It could lead to a very messy and smelly cleanup situation.

The majority of RVs constructed today use the "proper method" of having the Shower, Bathroom Sink and kitchen Sink drain into a grey water tank.

Since you are going to be looking at newer 2005 to 2009 5th wheel trailers, the owners or dealers that are selling these 5th wheels should still have the owner's manuals available. I would look at the specification sections of the owner's manual to get this information.

I wish you the best of luck on your Fiver hunting.

Shower plumbed to Black tank
by: Anonymous

I have a 2004 Keystone Springdale 280RKLS that the Shower was plumbed into the black tank. the sad part about it is that the manufacturer saved about 12 inches of PVC to not do it right.

Black tank
by: Steve Coker

I have a 2009 Keystone Everest with 1 1/2 bathrooms. The 1/2 bath's sink drains into the black tank for that toilet even though it has 2 grey and 2 black tanks. The way I found out was the toilet would'nt flush and the sink would'nt drain. Typically the smell would'nt come up thru the sink because there is a p-trap full of water.
