The short answer
- A whole-house system installs at the point water enters the home, so every tap is treated.
- Most installations are finished in one visit of three to five hours.
- Correct sizing to your flow rate is what keeps water pressure normal.
- Order matters: sediment first, then carbon or iron filtration, then softening.
What a whole-house system actually is
Point-of-entry (POE) treatment sits on your main water line, upstream of the water heater. Everything downstream — showers, laundry, dishwasher, ice maker, hose bibs — gets filtered water. That's the difference from a pitcher or a single under-sink filter, which only treats one point of use.
A typical stack for a Metro Detroit home is a sediment pre-filter, a carbon filtration tank for chlorine and taste, and a softener for hardness. Well homes often add iron or sulfur filtration and, in some cases, UV disinfection.
The installation, start to finish
- Water test and walkthrough — hardness, chlorine, iron, pH, plus flow rate and fixture count
- Placement — near the main shutoff with drain access and a nearby outlet, usually the basement or garage
- Shutoff and tie-in — main is off for a short portion of the visit only
- Plumbing the loop — bypass valve, unions for serviceability, drain line with an air gap
- Startup — backwash and rinse the media, set the control valve, check for leaks
- Walkthrough — salt loading, filter change intervals, warranty and maintenance schedule
Will it hurt my water pressure?
Not when it's sized to the home. Pressure complaints almost always come from a tank that's too small for the home's peak flow, or from a sediment cartridge that was never changed. We size to your fixture count and service flow rate, and we set filter-change reminders so restriction doesn't creep in.
What drives the cost
- Number of treatment stages your water actually needs
- System capacity and valve type
- Plumbing work at the tie-in — copper, PEX, or a tight mechanical room
- Whether a drain line, outlet or permit needs to be added
Choosing an installer
Ask for a written scope that names the equipment, the media, the valve and the warranty on both parts and labor. Ask who services it afterward — the value of a local installer is that the person who set it up is the one who comes back. We install and service every system we sell throughout Oakland, Macomb, Livingston & Wayne County, Michigan.
