Horrible customer service with part #s to buy adapter elsewhere...

Horrible customer service with part #s to buy adapter elsewhere...
I wanted to express my dissatisfaction with InSinkErators customer service and give people another option to avoid their games. I purchased the HWT-F1000S to replace an older failed unit of theirs. The new item arrived and was missing an adapter called the "snap-connect fitting" that you must have to install the new unit. The directions clearly stated the this fitting is not included. I called customer service to complain and was directed to buy the part at Carrolls Parts for $21! This did not sit well and I told the agent about my dissatisfaction. They responded by telling me they would ship the part out only if I supplied the serial # of the new unit. I was not at home at the moment and this made me even madder. This is what I have found out through some research how to get the part if you don't wish to be played.The part can be ordered through Fresh Water Systems online (www.freshwatersystems.com) using part # APC13004SH for $5.84 plus $4.95 shipping. I order three parts to see what would work and all three will work. The parts arrived in three days from Greenville, South Carolina shipped to Greenwood, Indiana. #APC13004SH is a non valved unit. It will drip a small amount when unhooked from the unit - for me this is desirable since I am using DI water and don't want the spring in the valve to come in contact with my filtered water). #APCD13004SH ($5.65) is the same except that it have the valve. #46000 ($7.16) is the same product I believe you can get from Carroll Parts - valved plus NSF tested (see pic far right).I hope people that share my frustration can use these part #s to get their heater up and working.
Thank you for your feedback
