Last updated March 16, 2020
Due to the COVID-19 emergency, effective March 17, 2020 until further notice, the SFPUC will temporarily suspend our Plumbing Fixture Replacement Program (PREP) pre-inspections and installations. Applications can still be submitted, and qualifying applicants will proceed with inspection and installation appointments once we resume regular operations. Please leave a message at (415) 551-4730 or email firstname.lastname@example.org if you have any questions or would like to schedule a water conservation phone consultation.
NEW! Watch our PREP video here.
The PREP Program replaces old fixtures with water-efficient models for residential account holders. To qualify, your property must have existing toilets that use 3.5 gallons per flush or more and/or urinals that use more than 1.0 gallon per flush. Residential properties purchased after July 1, 2009 are not eligible for participation, because San Francisco's Residential Energy and Water Conservation Ordinance requires that old non-compliant toilets and urinals (as well as faucets and showerheads) be replaced with water-efficient models before the property is sold.
Sites must accommodate installation of new high-efficiency models without major plumbing alterations or repairs. Properties with abnormal site conditions (e.g. rotted flooring, atypical plumbing configurations, etc.) will not be eligible for the PREP Program until conditions are improved by owners at their own expense. Participants are required to have showerheads, faucets, and/or faucet aerators that meet San Francisco's conservation ordinance requirements. Any devices that aren't compliant must be replaced by the time PREP installations are complete.
For qualifying sites, licensed plumbers with Bottom Line Utility Solutions (BLUS) under contract with the SFPUC will remove old toilets and urinals and install new ones for free. Replacement fixtures will be limited to models specified by the SFPUC; see our PREP FAQs for more details.
Please RSVP to the requested pre-inspection and installation dates to confirm your appointments, or your participation in PREP will be put on hold.
**If you or others in your household or business are sick, please kindly contact us at (415)551-4730 to reschedule your PREP inspection for another date.**
New Applicants: Please do not submit duplicate or multiple applications for the same property. For applicants interested in applying to multiple properties, please register/logon to conservation.sfwater.org and under Manage Accounts and Settings, click Linked Accounts. The ten-digit water service account(s) are required to apply.
Existing Applicants: If your site has already been pre-inspected and has eligible fixtures, please contact the SFPUC's plumbing contractor, Bottom Line Utility Solutions (BLUS) at 800-597-2835 or email@example.com if you have questions about your installation. We have a new way to view the status of your application anytime. In order to access our online portal, click here.
PREP Program Steps
The SFPUC’s Plumbing Fixture Replacement Program (PREP) is intended to serve entire buildings, as well as single-family residences. Property owners, property managers or water account holders, with the agreement of all three parties if they are not one and the same, may coordinate submission of a single application for all toilets and urinals in the entire building.
For additional questions, contact the SFPUC Water Conservation Section at (415) 551-4730 or firstname.lastname@example.org.
