Barker Auto-Drain Electric Waste Valve Actuator | 3" or 1-1/2" Valve

Dump the tanks from a switch instead of crawling under the rig. The Barker Auto-Drain bolts directly onto a conventional Bristol or Valterra slide valve and pulls the blade for you — no new plumbing, no clamps to adjust, and no need to drain the tanks to install it. A manual override keeps you covered if the battery dies.
