Water Softener Installation in Missouri

Of the 57 Missouri towns we route calls in, 50 are supplied by ground water and 7 by surface water. That split is the first thing to establish about any address here, because it is the best single predictor of how hard the water will be.

The short version

Of the 57 Missouri towns covered here, 50 are supplied by ground water and 7 by surface water. Which of the two an address draws from is the best free predictor of hardness, because water that has sat in rock carries calcium and magnesium out of it.

SoftenWell is a referral service, not an installer. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands. Every state page sets out who licenses plumbers there and where to check, so you can confirm before work begins. We install nothing, we sell no equipment, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call.

The pattern hereWhere Missouri gets its water

Neither figure tells you about your own address. Source type follows geology and infrastructure, not county lines, and two towns twenty miles apart routinely draw from different places. The town pages below name the system for each one.

CredentialsChecking a plumber in Missouri

Missouri has no state plumbing board. Section 341.010 of the Revised Statutes requires a certificate for plumbers working in cities or towns of fifteen thousand or more inhabitants, and the chapter elsewhere recognizes licenses issued by any county or city operating under plumbing rules, so the office that issued one is a local office. Start here. Ask the contractor which municipality licenses them and confirm it with that office before work begins.

If the water is leaving marks, the question is how hard it actually is.That is a measurement, not a guess, and it decides whether equipment is worth buying at all. We connect you with somebody who can test it. You are never charged and we sell nothing. We are a softener site by name; the line is broader.
