As of January 1st 2017 California law requires property owners (for properties built before 1994) to install water conserving plumbing fixtures for single family properties. It is currently not a point of sale issue but for realtors/owners it is a check box on disclosures. As sellers/landlords you will need to disclose whether the property is in compliance. So a definition of a water conserving plumbing fixture means any fixture that is in compliance with current building standards. Toilets will have to be the ones that use less than 1.6 gallons per flush, any shower head must have a flow capacity of less than 2.5 gallons per minute and any interior faucet should have less than 2.2 gallons of water per minute. There are a lot of nuances to the new law so feel free to contact me and I will forward you a good Q & A. Remember, this has been required along with seismic shut off valves for gas meters in LA cities, not LA County. This will be a point of sale sooner than later.
