Brand new construction home with everything Kohler. The bathrooms faucets are Purist 14402-4A-CP and they are leak. The one star review is not really for wear over time, which is to be expected. We already hired a plumber and had the valve changed. Rather it for the poor design quality at this price point. The Top Handle is held by a screw which will probably fall off the HEX key required to remove it, like it did during my attempt to take a look myself. The plumber was onerous but given the frustration and time this cost me today, money is nothing when discussing servicing this faucet. I had a favorable opinion of Kohler until today. Now I know to look closer at the servicing ease and feasibility when picking fixtures the next time.
