2019 Bullet 243BHS Black Water Drains

Quick question. Do the bathroom sink & shower drains end up in the black water tank or grey water tank?
I see my black water tank levels going up but the grey water tanks donít seem to raise much. Not sure if it is a sensor issue in the black water tank or whether it is in fact the drains going into the black water tank.

Your trailer has three tanks:

Fresh Water 43 gal
Waste Water 30 gal (black tank)
Gray Water 30 gal

The galley sink, bathroom sink and shower "SHOULD" drain into the gray tank, not the black tank. The only component draining into the black tank in your trailer "SHOULD" be the toilet.

You can verify this "in your parking spot" by adding 5 gallons of water to the galley sink and pulling the gray tank drain valve. You should get 4 or 5 gallons of water out of the drain. Repeat with 5 gallons in the bath sink and pull the valve and get similar results. Next, 5 gallons in the shower, same results. If any of those do not give you water from the gray tank, then you'll need to explore why, however I'd suspect that you'll get a volume of water from each addition to those three plumbing fixtures.

I wouldn't suggest pulling the black tank valve in your yard (unless you have a septic connection to the trailer) as you'll wind up with a mess to clean up....

Reading the specs for your TT, you have one, 30 gal grey and one, 30 gal grey tank. It is possible the shower and sink in the bathroom drain to the black tank. This is done for two reasons, 1, for ease of installation and thereby saving production expense. 2, to keep plenty of water in the black tank for proper draining and cleaning. Kitchen would then drain into the actual grey tank.
Best way to tell is with full hookups, run the sink and shower and verify if only the black tank fills.

I too found my black tank filling faster then I thought it should have been, so after testing I found my bath sink drains into my black tank, shower into gray 1 and kitchen sink into gray 2.

Yours may be different, definitely test it.
