Frequently asked questions
What is a main sewer line?
The main sewer line carries wastewater from a property’s drains to the public sewer system, so a problem there can affect several fixtures at once.
Why does a main line problem affect more than one fixture?
Because fixtures share that line, a blockage or failure in it can show up in more than one place, unlike a problem in a single fixture drain.
Should I keep using water if several fixtures are affected?
Limit water use in the affected property and avoid contact with sewage until a provider has inspected the problem.
Will Sewer Line Repair do the repair itself?
No. Sewer Line Repair is a referral service, not a plumbing provider. Callers are connected with independent local providers, and licensing, insurance and pricing should be confirmed directly with the provider before work begins.
