The Performa 268 with 742 LOGIX Timer is a complete regenerating control valve assembly used on twin-alternating commercial and industrial water softener installations. The 742 head is an electromechanical 12-day time clock, driving the valve through its regeneration cycle on a fixed schedule rather than by measured water use, which makes it a straightforward and robust choice where water usage is predictable. Supplied as a full valve and control head assembly, this is the same class of unit fitted as standard to Autotrol Performa 268 twin softeners, and is stocked by WrekinWater as a direct replacement when an existing valve has reached the end of its serviceable life.

Symptoms that mean you need this part
The 742 timer motor or gear train has failed and the valve no longer indexes through its regeneration cycle
The piston and seal stack are worn beyond what a rebuild kit can restore, with persistent leakage to drain or across the bypass
The valve body is cracked, split or has been damaged by freezing, over-pressure or age
The existing 268 valve is obsolete or beyond economic repair and needs replacing as a complete unit rather than piece by piece
Regeneration is happening at the wrong time, too often, or not at all, despite the timer being correctly programmed
Why it fails / why it matters
On a twin-alternating softener, the regenerating valve is the component that actually drives the resin bed through backwash, brine draw, rinse and refill while the second tank stays in service, so continuous soft water is maintained. The 742 timer initiates this cycle purely on a 12-day clock rather than measured flow, which is simple and reliable but means the whole valve and control head has to work correctly for the system to regenerate at all. When the piston, seals or timer mechanism wear out, the usual outcome is either a valve stuck mid-cycle, water running to drain continuously, or a system that stops regenerating altogether, and at that point replacing the complete 268-742 assembly is more practical than attempting a partial repair.
Why buy this from WrekinWater
WrekinWater has supplied water softener parts to installers, commercial engineers and DIY customers for over 15 years from its base in Bettisfield, Shropshire, and stocks the full range of Pentair Autotrol, Fleck, Clack and Kinetico valves and control heads. With more than 50,000 customers served and an Excellent rating on Trustpilot, WrekinWater is set up to get a complete replacement valve like this out quickly, which matters when a twin softener installation is relying on it to keep supplying soft water.
How to fit it
Before ordering, confirm the replacement valve's tank thread, riser tube diameter and distributor design match your existing installation
Isolate the softener system at the bypass valve and relieve pressure from both mineral tanks before starting work
Have a competent installer or commercial water treatment engineer disconnect the existing valve from the tank head, along with the drain line, brine line and any twin-alternating interconnect wiring
Transfer the riser tube and distributor basket into the new 268-742 valve assembly, fitting new o-rings as needed
Fit the new valve to the tank, reconnect inlet, outlet, drain, brine and interconnect wiring, then set the 12-day timer to the correct regeneration schedule
Return the system to service and confirm correct alternation and regeneration timing over a full cycle before leaving it unattended
