Black/Gray Tanks - need both?

[vonslatt]

Hi All,

In the interest of keeping-it-simple I'm considering a single 100 gallon black water tank instead of the traditional black and grey tanks.

The only thing that I can think of that might be an issue is "sloshing" while on the road sucking the trap water from sinks and letting vapors into the bus. That, I think, could be dealt with with a big ball valve to seal the sink drain while in motion.

What do you all think?

first off I know nothing about plumbing, but are there 1 way valves (I know they exist for air and things) for this sort of thing? other people probably have bettter ideas

thats what im doing on our bus, since we have no shower i did not see the need to have a gray tank, just the 46 gal black tank. The sucking effect should be no problem as long as the tank is vented well.

Since my conversion is a rather quicky one and frankly, I'm not too into having a shower unit (height is an issue in my bus), I'm happy just having a larger black water tank as well. Large enough for the toliet and kitchen.

So, how is the single grey/black water tank working? -Richard

Well, I haven't got to tanks yet, but I haven't come across any reason not to have a single tank, so it's still the plan.
