I'm trying to figure out what to do with the 3rd connector on my InSinkErator H-CONTOUR-SS. I have a WaterStone hot/cold filtration faucet model 1400HC-SS that doesn't have a connection for that 3rd connector.
I contacted both WaterStone and InSinkErator and both had equally useless advice. Basically InSinkErator said I have to buy a faucet from them. And WaterStone said I have to buy a hot water dispenser from them. Horrible customer service on both sides.
So I'm hoping I'm not the 1st person to want to do this and somebody can tell me what to do with that 3rd connector.
