Extension for Involve Hot Water Dispensers is rated out of 5 by 3.
Rated 5 out of 5 by Bart from Hot water dispenser extendender works! I am so glad Insinkerator solved the issue with our over 10 year old hot water dispenser. The extender through our new stone counter is the perfect solution. Thank you!!!

Rated 5 out of 5 by dbach0852 from Hot Water Despenser Have had this product now for 5 years and my wife and I love it. Great for hot cereals, drinks & recipes. When we changed out our counter top and it was thicker than our old one I was very glad that there was a extension that attached .

Rated 5 out of 5 by NavyDavey from Evolve Extension This little extension allows one to use the hot water dispenser with thicker (e.g., granite) countertops. Without it, the spigot can't be used (threads don't extend below the countertop). Works well. My only complaint is that this little plastic piece costs $30...

Would this extension work on a air switch in a thicker countertop application?
Hi Mrkarl, this is Van from InSinkErator® Customer Service. That extension is for Involve Hot Water Dispensers only. If you need an extension that will work on the air switch, we have an Extended Air Transmitter Kit (part number 78187) which can accommodate countertop thickness of 2-3/4". Please check with your nearest Home Depot location if this can be special ordered. For more inquiries or concerns, please do not hesitate to contact us through [email protected] and we would be happy to assist you. Thank you.
