Descaler and Water Softener in Tarzana.
End hard water for good.
The Water — Tarzana
Built for the local supply.
Tarzana water carries the same Colorado River hardness load as Woodland Hills and Encino. Scale inside a Tarzana water heater typically starts showing within two years, which is why a correctly sized descaler is a near-universal install in this corridor. We size every system to the actual reading at the meter, not to a neighborhood-wide assumption.
Tarzana sits on the same LADWP distribution system as Woodland Hills, which means chloramine disinfection and a hardness load that comes primarily from the Colorado River share of the MWD blend. The seasonal groundwater contribution shifts the mineral profile slightly from month to month, which is one reason we run a free in home water test before specifying any equipment for Tarzana homes.
What we tune the system for in Tarzana
- · Chloramine disinfection byproducts (TTHM HLRAA 34.4 ppb per LADWP 2024 CCR, MCL 80)
- · HAA5 14.9 ppb (MCL 60)
- · Hardness 6 GPG average for MWD Jensen supply (112 ppm CaCO3); groundwater blends vary by season
- · Arsenic 3.5 ppb average (MCL 10 ppb)
