Drain Master electric waste valves

[Durb]

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 and activating them with a hex key. Both stopped working recently so I took jumper wires and bypassed the switches, worked fine. I replaced the OEM switches with momentary 20 amp DPDT switches from Amazon and the valves now operate fast every time. Also installed new indicator lights. I don't think the OEM micro switches were up to the job long term.

Really helps the valves if they have not been used for a while. very simple to do.

I saw a thread on the 4.5v D-cell power boost on this forum and considered it, even researched battery holders on Amazon. I decided to go with the switches as Amazon had them for $2.70 each as some kind of add on item. The LED "open" indicators were a little spendy. The project was around 40 bucks including wire terminals and a mounting box, less than half the price of new factory switches.

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.

Glad you found a good solution. Not having dump valves that worked would be a headache causing issue.
