My understanding was that if the gray valve is left open (and the hose in the ground) the gray tank, once it hits a cetain level in the tank, will drain slowly on it's own (without the sani-con pump).Maybe this isn't correct?
Bobander,Thanks for your response. When the gray valve is electronically opened, will the blinking light on the valve switch keep blinking and will it harm the light or switch itself?Thanks- Roni
If you just let the gray water drain as you let water into it, you'll have nothing to flush the black tank and hose with.
A few more questions on the bypass tube and the sani-con unit- It sounds like the gray water level needs to be high enough to get the water to pass through the bypass tube. Do you know what the monitor will read at that point?Also, if the level is high and the bypass tube slowly lets the gray water drain, will taking a shower cause it to overflow into the RV? In other words, faster coming in and slower going out- will it cause a problem?Thanks- Roni
