Drain Master electric waste valves
Unfortunately, my ten year old trailer came equipped with electric drain valves and switch gear. They were nice when they worked which was about half the time. I became expert at crawling underneath...

I added Drain Master valves to my rv a couple years ago and have found them to be working perfectly and with plenty of power. This version has the metal gears. Are the earlier versions more problem prone? I try to keep the valve blade area cleaned and lubed as often as I can.
