I’m remodeling my laundry room and this space feeds a hose bibb that is used for washing cars, cleaning tools, etc. My location is NY, so it gets cold here. Washing road salt off the cars and cleaning tools after tiling last winter was quite painful. I’m considering changing out the supply to the hose bibb from a single cold water feed to a hot/cold water feed through a Watts ½” lo-temp mixing valve (60-120 deg F). Will I get an unacceptable pressure drop across the mixing valve? Would it help to install a ¾” valve with reducing couplings? The other option is to eliminate the mixing valve and install a pair of check and ball valves to manually mix the hot/cold. The valves will be inside the wall with an access panel. Any suggestions?
Thanks in advance,
