Product Information

The Autotrol^® 255 Valve with 940 Timer Control is available with your choice of a 7-day timer, shown here on a compact cabinet water conditioning system, or a 12-day timer.

How a Water Conditioning System Works
During normal conditioning, raw water enters the system at the top of the conditioning tank. As it seeps down through the conditioning bed, foreign particles are filtered and hardness minerals are collected on the ion exchange sites of the resin providing conditioned water for your home.
During the regeneration cycle, the system automatically regenerates the ion exchange resin.

New conditioning efficiency...built on a proven past.
