## Overview

The Barker 24130 3" Auto Drain is a 12V DC powered, corrosion-resistant automatic valve actuator designed for RV grey and black water tanks. Compatible with Valterra and Bristol 3" waste valves, it offers a quick 4-second open/close cycle, push-button convenience, and a built-in indicator light, making tank dumping faster, cleaner, and easier without plumbing modifications.

## Description

Auto-Drain provides completely automatic 12-volt push button operation of the valves that dump your RV's grey and black water holding tanks. It mounts onto the slide valve of a 3" or 1. 5" conventional waste valve and no plumbing modifications or difficult clamps are required. Works with Valterra and Bristol 3" and 1. 5" waste valve models (not included). Auto-Drain Valves are made of corrosion-resistant steel, aluminum and plastic. Before installing, your holding tanks should be emptied. There is an open or close cycle in less than 4 seconds for the 3" models. Included with the Auto-Drain Valve is a mounting bracket, rocker arm switch, switch box with light (indicates open or closed valve) and complete installation and operating instructions.

Review: Works like a charm - 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.
Review: Simple as pushing a switch and no more broken cables . Should be mandatory on all campers and rv’s - Pretty simple upgrade for rv tank dump. No more broken cables and unsanitary conditions involved with broken dump cables. Best upgrade ever for stubborn pull cables.

## Questions & Answers

**Q: Does this valve actuator have a manual override ? In other words can the valve be opened or closed in a no power situation?**
A: Actually if the auto drain is in the open position you can disconnect it from the handle with a wrench and manually close the handle but if the auto drain is in the closed position it blocks the handle from opening.

**Q: Will this work on cable driven valteera valves ? I under how it hooks to rod but does cable valves have a different set up we’re cable connects to val**
A: This unit does not use a cable at all. It is electric and needs a 12v power source.  It comes with a switch you use to open and close the valve.

**Q: No 12 volt battery on my trailer always plugged into ac, can you use a ac to dc converter with the barker auto drain (pyramid ps9kx converter)?**
A: Yes
12vDC is 12vDC.  There may even be a possibility of using the 12v from your trailer lights which it certainly must have.  You would only need to be plugged into your tow vehicle to use the valve.  Just need to check the load so you don’t overload the circuit and blow a fuse.

**Q: What size wire is needed to Install the switch farther than 4 feet from the unit?**
A: I simply added on the needed length (about 4 feet) using the same size as the valve came with.  This seems to be a common issue as the length supplied is to short for many applications.   Mine has been in use for three years with no issues.

### ⭐⭐⭐⭐⭐ Great product for what itvis
*by J***. on May 23, 2022*

If your planning on mounting the switches right next to the valves then it comes with everything you need. If you have a larger trailer or toy hauler with multiple tank locations and a covered underbelly, them plan on 1 to 2 days for install and an additional 50 to 75 feet of wire and connectors. I installed 3 valves and located my switches in my water management cabinet. Had to splice in extra wires on all 3 valves and switches. Took me 2 days, removing and installing the underbelly was the hardest part. Hopefully I don't have any issues with them.
