Water Treatment
Choose filtration based on water testing instead of salesmanship.

First, understand the job.
There is no honest “best filter” without first knowing what is in the water and what you want removed.
Step by step
Do it in this order.
Find the actual problem
Define the specific contaminant, taste, scale, or odor concern.
Make the repair
Compare certified treatment methods and realistic maintenance costs.
Test your work
Provide bypasses, drainage, pressure checks, and sanitary installation.
One last check
Dry everything, run the fixture more than once, and look again in ten minutes. A tiny drip now becomes cabinet damage later.
