MGA Plumbing is the O'Fallon plumbing company to call for water line repair. Our local plumbers are available 24/7, arrive on time and fix the problem right the first time. Respectful technicians who protect your home and clean up after every job.
Your main water line runs from the meter to the house and is your responsibility. Leaks show up as wet yards, low pressure or a jump in the water bill. We locate the leak, repair or replace the line (often trenchless) and coordinate the utility shut-off.
New copper or HDPE service lines resist corrosion and roots and typically last 50+ years.
