Guage no work, how do I know when GREY tank is full?

[stevek]

My Gauge always shows Zero, like it is not working.
What are the indicators the GREY tank is full?
Wheres the first place it will back up? In the shower?

I have a SeeLevel II Tank Monitor.
Anyway to fix the problem?
Any suggestions?
Thanks

BTW.... I have a dumb question.
Why do they have two tanks anyway?
Instead of a GREY and BLACK, why not just one big tank?

Steve,

Yes, if your Born Free's shower drain dumps into your gray water tank, then the first sign that the grey water tank is over-filled will be water showing up in the bottom of your shower.

Steve, prior to Born Free using the SeeLevel system I installed their 709PH model in our 2002RB. If the system is initially programmed correctly I found it to be very accurate and dependable. If you are not able to correct your problem by referring to the Troubleshooting guide in owners manual I would give Garnet Technologies a call as they are very helpful.

You can water your lawn with gray water. You probably don't want to do that with Black water......although I have when it is not black but yellow water

I always dumped some ice in the black tank thru the toilet to clean my sensors in my 5th whl but not sure how you could do that with the gray tank?
