Auto Drain

Catalog Item # 51560

Empty holding tanks effortlessly, with the flip of a switchÑnow with LED indicator!

Eliminates bending, reaching and straining to open the waste valve on your RV. Just attach the hose and flip the switch to drain tank. New LED indicator on switch shows when valve is open, to avoid accidental leaks and spills. Easily replaces your manual valve, offering longer life and greater reliability because it uses the same pressure every time the valve is opened or closed. Draws less than 2500 milliamps of 12-volt power during operation. Opens and closes in less than 2 seconds. Manual override if power fails. Fully sealed motor with no external moving parts. Made of aluminum, stainless steel and ABS plastic, so it’s impervious to rust. Includes switch with LED indicator and label for mounting near valve; add an optional secondary switch (sold separately) for inside or outside operation. Fits 3” valves; use optional reducer kit (sold separately) for 2” or 1 1/2” valves. 6”H x 10”W x 11/2”D.
