Plumbing Fixtures: Water Saving Standards

How manufacturers of plumbing fixtures sold in Texas can certify that their products comply with water saving performance standards.

You may not sell, offer for sale, distribute, or import a plumbing fixture for use in this state unless:

(1) it meets the water saving performance design standards; and

(2) it is included on the TCEQ’s list of plumbing fixtures certified to meet those standards.

What are the maximum allowable flow rates for plumbing fixtures?

Sink / lavatory faucet or a faucet aerator - 2.20 gpm at 60 pounds per square inch pressure
Shower head - 2.5 gpm at 80 pounds per square inch pressure
Commercial pre-rinse spray valve - 1.6 gpm
All drinking water fountains shall be operated by a self-closing valve
Toilet - 1.28 gpf (dual flush cannot exceed 1.28 gallons for an average flush volume of two reduced flushes and one full flush)
Urinal - 0.5 gpf

How do I get plumbing fixtures included on TCEQ’s list of certified fixtures?

Submit the following information:

(1) the identification and performance specifications for each plumbing fixture product intended for sale and use in the State of Texas; and

(2) certified test results from a laboratory accredited by the American National Standards Institute (for each fixture) verifying that the plumbing complies with the flow requirements established in 30 TAC 290.252(b).
