TOTO ECOPOWER Concealed Toilet Flush Valve with V.B. Set, 1.28 GPF – TET2LB31/32

The TOTO TET2LB concealed ECOPOWER toilet flush-valve packages combine a 1.28 GPF valve with a vacuum-breaker set for the selected spud location. These commercial flush-valve kits are not complete toilets; the compatible toilet fixture is sold separately.

• Hydroelectric ECOPOWER operation generates power from water flowing through the valve.
• Heavy-duty 14-inch by 12-inch satin stainless steel cover plate, bronze valve body, self-cleaning piston and filter, and manual override.
• Back Spud wall-hung packages specify the VB1331R#RB vacuum-breaker set; Top Spud packages specify VB0932R#RB. Both specify a 1-1/2-inch vacuum-breaker tube and 1-inch angle stop.
• Standard packages use the TET2LB#SS valve. IoT Ready and IoT Enabled packages use the TET2LBi#SS valve.
• IoT Ready packages require a communication card sold separately for IoT functionality. IoT Enabled TET2LBi431#SS and TET2LBi432#SS packages include the THP3566 communication card.
• For compatible commercial 1.28 GPF water closets. Confirm spud location, rough-in, wall clearance, supply pressure and installation requirements in the official specifications before ordering.
