Review on 🚗 Efficient Auto Drain: The Barker Valterra-Bristol Model by Justin Anderson

This unit arrived on time and took about 2 hours to install in total. I installed it on the gray water tank and routed the wiring inside next to the water level gauges. We installed a washer dryer and wanted to be able to drain the gray water without having to run outside to drain. I didn't want to install black water as I want to be close to the drain hoses when draining in case there is a problem. I had enough wire in the included harness to get to my switch. The valve assembly is simply placed behind the basement door with the valve open and the door closed. I did the entire installation myself, but it's not the easiest task if I'm not experienced. This is the #1 upgrade we've made to our RV!
