Pfister’s PermaBalance in-wall tub and shower valve has a new brass stem, larger ceramics, a more flexible install depth for shallow wall installations and a high precision spool balancing unit. It offers years of trouble-free service, while still being able to pressure-balance down to flow rates as low as 0.5 gpm at the showerhead.
