Kansas City plumbing questions
Is Kansas City water hard?
Moderately. KC Water reports average hardness around 100 mg/L, or 5 to 6 grains per gallon, from mostly Missouri River water. The river's quality shifts with rain, snowmelt and upstream releases.
Why do roots get into Kansas City sewer lines?
Many older homes have clay laterals with joints every few feet. Roots from mature trees find the moisture at those joints and grow inside, which leads to recurring clogs. Cutting or jetting clears them for a time, and relining or replacing the damaged section stops them for good.
Who licenses plumbers in Kansas City, Missouri?
Missouri has no statewide plumbing license, so licensing is local. Ask which Kansas City license the plumber holds and confirm it with the city before work starts.
