The Haws 1011HO ADA Hi-Lo stainless-steel drinking fountain incorporates a touchless sensor operated stainless steel solenoid valve controlled by a transformer for hands-free operation on one side and offers the only all stainless-steel valve body that is machined out of solid bar stock on the other. It is fully serviceable through the front of the push-button assembly offering access to the water control cartridge and integral water supply strainer and has front access to the water stream height adjustment for easy maintenance without having to remove the valve.
