Autotrol 1000269 Injector Cap with O-Ring for for 255, 263, 268, 278 Logix Valves and 367 and 368 peanut valves

The 1000269 is the injector cap and o-ring that retains the venturi injector inside Autotrol Logix 255, 263, 268 and 278 valves and the 367 and 368 peanut valves, sealing the injector chamber so the venturi can draw brine correctly during regeneration. It's a small, low-cost part but a failed cap seal is one of the most common reasons a softener stops drawing brine properly. WrekinWater stocks this cap for installers and homeowners troubleshooting weak or non-existent brine draw on these widely-used Autotrol valve platforms.

Technical specifications

Symptoms that mean you need this part

• Little or no brine is being drawn from the salt tank during regeneration
• Water is weeping or spraying from around the injector cap during the brine draw cycle
• Softened water quality drops off between regenerations even though the cycle appears to run normally
• The o-ring is visibly perished, flattened or missing when the injector housing is opened for inspection

Why it fails / why it matters

The venturi injector creates the vacuum that draws brine out of the salt tank during regeneration, and it only works if the injector cap seals the chamber completely so all the vacuum is directed through the injector nozzle rather than leaking past the cap. The o-ring on this cap sits under constant water pressure and is disturbed every time the injector is cleaned or inspected, so it hardens and loses its seal over time, allowing air or water to bypass the venturi effect. Once that happens the softener can complete a full regeneration cycle on the display while drawing little or no actual brine, leaving the resin bed under-regenerated without any obvious fault code.

Why buy this from WrekinWater

WrekinWater has stocked Autotrol Logix and peanut valve spares for over 15 years from its Bettisfield, Shropshire base, and knows that weak brine draw is one of the most common calls installers get about an otherwise healthy-looking softener. With more than 50,000 customers served and an Excellent Trustpilot rating, WrekinWater keeps parts like the 1000269 injector cap in stock so this common fault can be fixed for a few pounds rather than assumed to be a bigger valve problem.

How to fit it

1. Isolate the softener at the bypass valve before opening the injector housing
2. Locate the injector cap, usually accessed from the side or top of the valve body near the injector screen
3. Unscrew or unclip the cap and withdraw it along with the venturi injector and screen
4. Remove the old o-ring and clean the cap and housing thoroughly, checking the injector nozzle for scale or debris at the same time
5. Fit the new 1000269 cap and o-ring, lubricating the o-ring lightly, and refit the injector and screen in the correct orientation
6. Restore the water supply and run a manual regeneration to confirm brine is being drawn correctly with no leaks at the cap
