Sunnybrook grey water

[Snap-On Man]

My 2004 Sunnybrook 5th has 2 grey water tanks. Is one for the kitchen sink and the other for shower and bathroom sink? Or shower for one and sinks for the other? Any body know?

Do you have a rear kitchen or bathroom? Dual reservoirs are usually area specific. Some units have an upstairs bath as well as a rear bathroom and it will have a separate tank.

Shower and bathroom Sink are up in the bedroom area. Kitchen sink is mid way on the curb side. Getting ready to camp with no hookups and just want to use my tanks wisely. May need to run water in each one, one at a time and test. Just thinking someone may already know.

My last TT had 2 grey tanks. One for the rear kitchen and the other for the shower and bath sink in the middle of the TT. I'd bet yours is the same.


Just open one of the valves and run water from each and you'll see which one doesn't flow. That one is on the other tank.

My back tank is also galley only.

x3 here. Shower/Bath Sink are one tank, other tank just for the galley.

Annoys me, they are the same size tank (55+ gallons each)...guess which one always fills up? Its not the kitchen.... I need to figure out a way to cross connect them and offload shower water....
