Next steps for Houston, MO
Look up your address in Houston Pws's service line inventory. If it says lead, galvanized or unknown, test your tap. If your own line is lead, replacing the private side runs about $1,200-$12,300 (EPA average about $4,700). Ask Houston Pws whether it covers that cost before hiring anyone - many utilities now do.

The lead result guide covers how utilities pick the homes they sample. Small systems behave differently: why small systems go over more often.
