What to do in your house
Look up your address in Rubidoux Community Sd'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 Rubidoux Community Sd whether it covers that cost before hiring anyone - many utilities now do.
