From experience in the field, we have found that if the
unit fails to regenerate, you will have either a dead timer motor, a
stripped gear ( or two ), or a broken post that holds a gear in the 440
Timer Housing.
Problems related to improper, or incomplete regeneration
are due to: air leaks in the brine tubing connections to brine pick up
tube, clogged drain lines, valve discs that have worn out ( after 10
years ) or valve discs ( and all internal rubber components ) being
damaged when used on a chlorinated water source.
