Water Treatment and Filtration | Oakland & Macomb County

The short answer

Start with the complete system and the evidence

Water treatment should address a measured water condition and the fixtures or equipment you want to protect. Sandison reviews the water source, test information, flow, pressure, and maintenance needs before recommending softening, filtration, or a combination.

Water condition first

Treatment should be selected from the water source, measured problem, and intended use

Southeast Michigan properties can receive municipal water or private-well water, and the treatment decision changes with hardness, iron, manganese, sediment, chlorine, odor, taste, microbiological concerns, and the plumbing or equipment being protected. Sandison reviews the source, existing test information, flow demand, pressure, pipe size, available drainage, electrical needs, service space, and current equipment before recommending softening, sediment filtration, carbon filtration, reverse osmosis, ultraviolet treatment, or a staged combination. A filter rating alone does not establish that a system will solve the reported problem.

Installation and maintenance

A treatment system must protect flow, allow bypass, and remain serviceable

Good treatment design includes more than placing vessels in the mechanical room. The piping layout should preserve practical flow, include appropriate isolation and bypass arrangements, provide drainage and electrical service where required, and leave room for media, filter, membrane, lamp, or control maintenance. Sandison also considers the effect of hardness and sediment on water heaters, tankless heat exchangers, fixtures, valves, ice equipment, and other connected systems. The owner receives a maintenance path based on the installed equipment and actual water conditions.

Common questions

What property owners ask

Do I need a water softener or a filter?

Start with the concern: hardness, sediment, staining, taste, and odor can call for different treatment. Water-source information and testing help select the appropriate equipment instead of relying on a filter label alone.

Can treatment equipment reduce water pressure?

Flow demand, pipe size, equipment condition, and filter or media restrictions affect pressure through a treatment system. The design should preserve practical flow and include access for service and appropriate bypass arrangements.

What should I bring to a water-treatment consultation?

Share whether the home uses a well or municipal water, any recent test results, and the symptoms you want to address. Information about current equipment, filter changes, staining, scale, and pressure changes helps focus the recommendation.
