Three of our sales reps recently helped a customer wanting electronic sensor faucets to replace his Delta single lever faucets. The problem was that the granite or solid surface countertop was only drilled for two holes, 4” centers. Usually the basin or deck is made with three holes with the outside measuring 4” or 8” apart, center to center. The third hole is usually in the center of the other two. Most hands-free sensor faucets have the water supply feeding through the center hole of the deck and the outer holes are used to mount the faucet to the deck. The solution? The T&S Brass faucet. Best #99153793, #99782908, and #99872177 will all work on a two-hole deck.
