BARKER Manufacturing Company 24140 1.5" Auto-Drain

Fairly easy install if you make it easy, i chose to mount my control switch INSIDE my rig so i had to run more connection wire as the product only comes with maybe 3ft.of prewired pigtail connection. But beside that all straight forward plug and play hook up and the instructions are well explained and illustrated.

This purchase was the second auto valve I have purchased. The first one was damaged in a tire blowout. I was happily able to use the same connector as the previous install. These thing are great. I Installed them because I have an injured back and bad knees. This was a very difficult chore as the location of the drain valves required me to bend and lean forward under the Travel Trailer to release them.No longer have to do this. This chore is now quick, easy and clean.However my one complaint, not product related, is the advertisement of the product. The ad and indeed the box it comes in is deceptive. It shows the product with a drain valve attached as if it comes as a complete unit. THIS IS NOT THE CASE. YOU STILL, NEED TO HAVE THE ORIGINAL VALVE OR A REPLACEMENT INSTALLED IN ORDER TO USE THESE ACTUATOR AS INTENDED. So just be aware of this requirement and ignore the pictures.

Best addition to my rv wish I found them years ago

It took a while to get the system adjusted that the motor quit when the valve is opened and when the valve is closed. But it sure beats kneeling on the concrete (I'm 70+) to pull on the handle. Highly recommended for old geezers like me.

I modified the stock switch housing to allow a second switch inside the RV as well as outside. Now I can dump from inside or outside! I also got this on a warehouse deal, score!

easy install works great

It was only the actuator I needed the complete valve was not compatible with what I had

On the older version Bristol valves, you have to modify how the valve stem connects to the motor. The bolt that comes in the kit is too short. The 3” kit was good. FYI!!
