Introducing the first truly universal fill valve – the PRO45U. Based on our PRO45 platform, the PRO45U is built to fit every toilet out there – from the old 5 gpf to the new 1.28 HET toilets to special toilets like the TOTO® Drake and Kohler® Cimarron. The PRO45U restores them all to factory specifications thanks to six refill diverter inserts and our patented water saving refill adjuster. Now plumbers don’t have to worry about having the right fill valve on their truck. With the PRO45U, plumbers know they have the right fill valve for any toilet.

  • Bowl refill rate can be adjusted to meet factory spec of toilet
  • Ultra-quiet operation
  • Minimal water hammer

  • Easy to install and adjust
