Maytag dependable care, washer in the air gap
This device is required by plumbing codes, but the likelihood of it ever causing a problem by not having it is about nothing, yes you can bypass it. Many people did do this if it’s leaking or you just don’t want it.
It does not regulate or control the flow of water into the tub. That was not. Its purpose the flow of water is regulated by the flow washers that are built into the inlet valve. John | ||

 Quick terminology check: The original post asks about the injector "valve", but based on the context, I presume they mean the entire assembly. Dan confirms "siphon break", and John confirms "air gap" and the code requirement behind it. ... but from Maytag's naming perspective, the "valve" is a specific part of that assembly. We have the "Injector" (cone shaped plastic bit), the "Injector Valve" (the flexible conical rubber part around it), and the "Injector Sleeve" (the plastic part that catches the sprayed water and directs it to the hose that connects to the wash tub). Earlier Maytags (I'm beyond my knowledge, Highlander-era?) had just a metal nozzle spraying into a metal catch funnel, without the rubber "valve" part. Is/was the expanding "valve" part itself actually required for code compliance, or just the air gap? Was there a specific reason or issue the valve was added to resolve? | ||

Maytag inlet air gap’s
Hi Dave, good questions the older Highlander, Maytag‘s just had a little copper tube as you mentioned the problem with the system is minerals would build up at the end of the tube and it would spray off to the side and leak, when they put the so-called injector valve in the intention, was to stop leaks, and it worked pretty well, but the little rubber piece would wear out in these and it would leak Also.
Both designs serve the same function and we are required by plumbing codes all automatic washers that are hooked to plumbing, have some sort of air gap built into the fill system. John | ||
