When your RV’s waste valve control switch sits far from the tank access point, this 10-foot extension harness bridges the distance with a simple plug-and-play connection. Compatible with both 1-1/2-inch and 3-inch Valterra E-valve models, it works with most standard RV dump systems.

The semi-universal design accommodates different valve brands while the black 10-foot cable delivers reliable power transmission for trouble-free tank dumping. No cutting, splicing, or additional wiring required—just connect and operate.
