I spent part of this past week traveling for the first time with my teenager. She was a good sport about it, but frankly most teenagers detest RVs on general principle (because RVs are for old farts) and she is no exception. I was very grateful for one of the fail-safes that my husband and I installed, that being the gray water tank emergency overflow valve (installation instructions here
). Because guess what?? We overflowed the tank.
Twice I shut the sink cover with the faucet handle in the wrong position and it started to run. I caught it quickly both times, but those errors plus her unfamiliarity with the need to conserve water while RVing were cumulative, and sure enough, when I went to slug the dump hose by releasing the gray water, I was greeted with evidence of an ongoing overflow event. But because we had installed the emergency relief valve, there was no water back-up into the shower pan or flooding of our coach.
In another thread I mentioned the difference between computational knowledge and experiential knowledge. Experientially, the gray water limitation was reinforced for me during this process. After we got home, I hooked up my 50' garden hose and measured the flow rate within our Interstate. The gray tank overflows at an equivalent of about four minutes of cumulative open-tap water use. That represents a pretty unforgiving performance envelope.
