Drain & Sewer Services in Southern Maine
Drain and sewer problems have a way of escalating quickly. A slow drain becomes a backup. A partial blockage becomes a complete one. A small crack in a drain line becomes water damage in the ceiling below. AT Plumbing Services handles drain and sewer work across Southern Maine with the full-service approach of a complete plumbing company — not the single-service, run-a-snake-and-leave approach of a drain specialist.
That distinction matters because the real cause of a drain problem is often not what it looks like at the surface. Multiple slow drains can indicate a main line issue rather than individual fixture clogs. A sewer smell without a visible blockage often traces back to a failed house trap, a dry floor drain, or a cracked vent stack. We find the actual cause before recommending work — and we fix the actual problem, not just the symptom.
House trap removal is a specialty service we offer that most plumbers in Southern Maine don't. Older homes — and Southern Maine has many of them — frequently have house traps that are obsolete, not required by current code, and a primary contributor to recurring main drain blockages. If you've had your drain cleaned repeatedly and the blockage keeps coming back, a house trap is worth investigating.

Signs Your Drain or Sewer Line Needs Attention in Southern Maine
Multiple slow drains throughout the home
An isolated slow drain is typically a local blockage. Multiple drains running slowly at the same time usually indicates a main line issue.
Gurgling sounds from drains or toilets
Air trapped in the drain system — often a venting problem or a partial main line blockage affecting multiple fixtures.
Water backing up in unexpected fixtures
Sewage or water backing up into one fixture when you use another indicates a main line obstruction that needs immediate attention.
Sewage smell inside the home
Can indicate a dry floor drain trap, a cracked drain line, a deteriorating house trap seal, or a failed wax ring. We trace the source systematically.
Cast iron drain system in a home built before 1970
Cast iron corrodes and deteriorates over decades. Inspection is advisable in any pre-1970 Southern Maine home — especially before beginning a remodel that will open walls and provide access.
