Q: Does this need batteries to work?
No, it works purely mechanically, like a wind-up egg timer, so there are no batteries or electronics to fail or replace.
AA323 - Single-Outlet Mechanical Water Timer
Water timers just don’t get any easier to use than this. Simple and reliable, it works like a mechanical egg timer, without batteries or electronics, automatically shutting off the water after a chosen length of time (up to 2 hours).
The large rubberized dials offer good grip even when wet, with high-contrast numerals that are easy to read. A manual override setting lets you use the hose without engaging the timer.
The timer works with water pressure from 15 to 120 psi and has a durable plastic housing.
Instructions not included – you simply won’t need them.
