Water Treatment
Choose treatment for a specific goal: mineral scale, whole-home filtration or drinking-water filtration. Leon Plumbing installs and services softeners, filtration and reverse osmosis with attention to water conditions, access and ongoing care.
Softeners, filters and RO solve different problems
A softener addresses hardness minerals. A whole-home filter targets substances covered by that filter’s design and rating. Reverse osmosis treats water through a membrane and is commonly used at a dedicated drinking-water outlet. These are not interchangeable systems, and no device should be assumed to remove every possible contaminant.
Discuss the current concern and review utility information plus appropriate property-level testing. We do not assign a single hardness value to every address in a city. Treatment selection should follow the measured conditions, desired outcome and equipment specifications, with any health-related contamination concern referred to the relevant water authority.
Plan installation around the service route
A whole-home system needs a suitable position on the correct supply branch, capacity for demand and accessible bypass valves. Drainage, power and local discharge requirements may affect softener placement. Under-sink RO needs usable cabinet space, a safe drain connection and an appropriate outlet. Existing pressure and flow should be checked so treatment does not conceal a separate plumbing fault.
Keep maintenance part of the purchase decision
Filters, membranes and other consumables need replacement according to the installed model, usage and water conditions. Salt-based softeners require appropriate salt care and operational checks. Reduced flow or changes in taste can be clues, but they do not identify the cause without inspection. Keep service records and budget for ongoing consumables rather than considering only the initial installation.
Where treatment is intended to help protect a water heater from scale, coordinate the plan with the heater manufacturer’s requirements. Treatment does not remove the need for model-specific heater maintenance. We explain what the proposed system does, what it does not do and how to use its bypass and shutoffs.
