Sewage Pump
Sewage Pump Replacement
At Septic Advisor, we specialize in professional sewage pump replacement, ensuring your system functions properly and prevents costly damage.
A sewage pump is essential for moving wastewater from your home or business to your septic system or municipal sewer line, especially in properties where gravity alone isn't enough. When a sewage pump fails, it can lead to slow drains, backups, foul odors, and even flooding.

Sewer Line
Sewer Line Replacement
At Septic Advisor, we specialize in professional sewer line replacement throughout Southern Maine, ensuring your system is restored with minimal disruption and maximum efficiency.
Your sewer line is a critical part of your plumbing system, carrying wastewater safely away from your property. Over time, sewer lines can become damaged, clogged, or collapse, leading to slow drains, sewage backups, foul odors, and costly property damage.

D-Box
Distribution Box Replacement
At Septic Advisor, we provide professional D-box replacement services throughout Southern Maine, ensuring your system operates efficiently and prevents costly repairs.
The distribution box (D-box) is a critical component of your septic system, responsible for evenly distributing wastewater from the septic tank to the drain field. Over time, D-boxes can crack, shift, or become clogged, leading to uneven drainage, backups, and potential system failure.

Drain Field
Drain Field Services
At Septic Advisor, we provide comprehensive drain field services throughout Southern Maine — from inspections and repairs to full drain field replacements — ensuring your septic system meets Maine DEP standards and functions efficiently year-round.
Your drain field (also called a leach field) is the final stage of your septic system, responsible for filtering and dispersing treated wastewater into the soil. In Maine's climate, freeze-thaw cycles, heavy rainfall, and soil conditions can take a toll on drain fields, leading to failure if not properly maintained or replaced.
Learn MoreSewer Jetting
Sewer Jetting
At Septic Advisor, we provide professional sewer jetting services throughout Southern Maine, clearing even the toughest blockages and restoring your sewer or septic lines to like-new condition.
Sewer jetting (also called hydro jetting) uses high-pressure water to blast through stubborn clogs, grease buildup, tree root intrusion, and sediment deposits in your sewer and septic lines. It's the most effective way to restore full flow without damaging your pipes.

Laura Gelinas
September 2026
We were so happy with everything from Septic Advisor. We had an emergency — a failed pump and, unbeknownst to us, a crumbling wall in our pump station. I reached out to Septic Advisor and in less than 24 hours they solved our emergency situation. They promised and delivered a prompt, fair quote. They were professional, thorough, easy to work with and went the extra mile for us.

Wonderful experience with Septic Advisors!! So grateful to have found them after our leach field had failed. Mike and his son went above and beyond to help us make a plan that best fit our property and budget, made quick and thoughtful work of it, and were incredibly communicative every step of the way.

We needed septic repair services in Windham, ME and they came right out, were super clear with what we needed and did it. Will definitely use them again!
Septic service FAQs
Yes. We handle septic system design, Maine DEP permitting, and installation for new and existing properties in South Portland and Southern Maine. The system is sized to your soil, lot, and household so it stays code-compliant.
Slow drains, gurgling pipes, sewage backups, foul odors, standing water near the drain field, or unusually green grass are common warning signs. Call us for an inspection before a small failure becomes a full replacement.
Most tanks should be pumped every 3 to 5 years, depending on household size, water use, and tank capacity. Regular pumping prevents clogs, backups, and drain-field overload. We can set a schedule for your property.
