Can you leave black and gray water tank open?

You can leave your gray valve in the open position so water runs right down the drain. You don’t have to pay any attention to how full your gray tank is and you don’t have to dump it every few days. But there’s no chance for sewer odors to escape either.

How long can you leave your black tank?

A travel trailer black water tank will will typically last 5+ days if you are a couple camping or alone. If you have kids, expect your black water tank to last less than 5 days. Depending how you use it, you can extend your black water tank to last even longer.

How are the valves on a waste tank secured?

The valves are secured in place by 4 – 7/16ths inch nuts and bolts. I undid the black tank valve bolts and soon discovered my first problem. The valve would spin around but no way was it going to slide out.
