17 years on one and no issues. The only reason that they would fail is a puncture. Is your hose getting bound up or mouse chewed?

I do know why my fail and it is not the air part of the switch. they appear to either burn up or short out. Just wondering why. I have an insikerator disposal, I don't over load it and it never trips the overload switch, but I sure seem to have bad luck.

Just bought an Insinkerator disposal and air switch which gets installed next week. I’ll be watching this thread too.

So it’s the disposal and not the switch? Because the switch does nothing. It’s just a switch. AorB. Not electric.

Mine is at least 10 years old. No problems.

My difficulties are with the part of the air switch unit that plugs into The wall outlet. The disposal plugs in to this unit. The counter top push button that connect to a air hose then plugs into this wall unit. when the wall unit fails and I take it apart it has burned connections. The disposal still works just fine and when I put a new air switch unit in there is no problem for a period of time. So to clarify, the disposal unit works just fine through these various switches, the air push button works just fine, and I have not had to change the air line. I don't have any signs of mice chewing on anything, but I seem to burn up the electrical part of the air switch unit. Guess I am just having bad luck. I will be putting in a new switch later today and will post a report on the insides of the air switch.

You might want an electrician to take a look at that outlet.

It is fine. It works with a light bar when the air switch ceases to function. We use a light bar that has a mechanical switch to turn the disposal on and off. when I put the new wall unit for the air switch in I will take my multi meter and and check the voltage.
