REVERSE OSMOSIS • TEMPLETON
Water Fixers helps Templeton homeowners plan and service under-sink reverse-osmosis systems. For properties served by Templeton Community Services District, current utility data can inform the conversation, but the treatment decision still depends on the drinking-water goal, feed water at the property, pressure, plumbing and any existing treatment.
Templeton Community Services District reports groundwater from the Atascadero Basin and Salinas River underflow. Confirm the property’s actual provider or well status before applying utility-system data to a specific home.
Compare the current CPS, SPS, EPS and UPS configurations, then confirm cabinet/tank/faucet fit and pressure.
No water, low flow, leaking, noise, taste changes or constant running should be diagnosed before parts are guessed.
Use the dedicated maintenance, filter, membrane or sanitizing page when that task is already known instead of treating routine service as a repair.
If the goal involves hardness, sediment, odor or whole-house concerns, start with testing and the local water guide.
TEMPLETON WATER CONTEXT
For properties served by Templeton Community Services District, the 2025 Consumer Confidence Report says the District draws from the Atascadero Basin and Salinas River underflow. Its 2025 system-level hardness result was 459 mg/L as CaCO3 (27 grains per gallon), with a range of 84–642 mg/L, and total dissolved solids were 808 mg/L, with a range of 620–1,000 mg/L. These are utility-system results—not a faucet test or an automatic reason to install reverse osmosis. Use the property’s actual feed water, treatment goal, pressure, existing treatment and service history to choose the next step.
INSTALLATION IN TEMPLETON
If normal prefilters are current but production or treated-water quality is still questionable, membrane performance can be evaluated in context rather than replaced automatically.
Use the tabs for a clear side-by-side starting point. Stage count is one configuration detail—not a quality ranking. Open the full model page for the exact current component package and service information.
Water Fixers offers seven reverse-osmosis systems across the CPS, SPS, EPS and UPS families. Use these tabs for a compact view of the documented configurations, then open the full model page or comparison page for current components and service information. Stage count is one configuration detail—not a performance ranking—and Templeton does not determine the model.

Not sure which one fits? Start with the drinking-water goal, feed-water conditions, pressure and available installation space. The city does not determine the model. Compare all Water Fixers RO systems →
A new system should be selected from the actual treatment goal, component sequence, pressure and service access.
Filters, tank pressure, feed pressure, shutoff behavior, tubing, drain routing and membrane condition can create overlapping symptoms.
Water Fixers can evaluate systems it did not originally install when the configuration and parts are serviceable.
WHAT WE CONFIRM
Local water context can help with planning, but every property still needs its own source, plumbing and treatment-goal check.
Use the Templeton Water Quality Guide for source context and testing when the treatment goal is uncertain.
Check feed pressure, tank/faucet/drain layout, existing filters/softener and future service clearance.
Identify the system and normal cartridge history before ordering filters, a membrane or replacement components.
Use the dedicated page for the actual job—installation, maintenance, repair, filters or membrane service—so you can go straight to the relevant information.
Membrane-specific work routes to RO Membrane Evaluation & Replacement.
Use the Templeton plumber and water-quality guide when the question extends beyond the RO system itself.
Tell Water Fixers whether you are planning a new system, servicing an existing RO or trying to understand the water goal. We can route the next step without making the city name stand in for a diagnosis.
