Water filtration in West Lake Village.
West Lake Village is served by Las Virgenes MWD rather than LADWP, which means a different utility, a different treatment profile, and a reliably high hardness load from the imported Colorado River share of the blend. At 8 GPG, the scale accumulation inside a water heater here is noticeably faster than in the LADWP zone to the east. Most homes in this area benefit from a softener and whole home filter running in tandem.
