Plumbing Fixture Retrofit Requirements

  • Toilets which are manufactured to use more than 3.5 gallons per flush (gpf) must be replaced with Ultra-Low Flush Toilets (ULFTs) that use 1.6 gpf or less. Modifications intended to reduce the flow of an existing toilet, such as the use of toilet bags, dams, bricks, or other alternative flushing devices, are not permissible and do not comply with the Code provisions.
  • Showerheads that emit more than 2.5 gallons of water per minute (gpm) must be replaced with a low-flow showerhead that uses no more than 2.5 gpm. Showerhead flow restrictors are not acceptable. The entire showerhead must be replaced with a low-flow model.
  • Sink faucets (bathroom, bar, and kitchen sink faucets) that use more than 2.2 gpm must be retrofitted. Faucet aerators may be installed to reduce the water flow.
  • Reverse Osmosis Systems require automatic shut-off valves.
  • Urinals that use more than 1.0 gpf must be replaced with low-flush models. The entire fixture must be replaced, not just the flush valve.
