Our faucet was 3 yrs old 6/8/20. Last night we noticed a pool of water under sink. The pull out spray hose had a pin hole leak about half way down the hose and would spray water when sprayer was pulled out. Unfortunately there is no way to replace hose and had to replace with another faucet. Also will have to replace bottom of cabinet as this must have been happening for a while and base is warped badly. Need to be able to replace spray hose. Been a longtime customer of Kohler but this is unacceptable.
