Looking for an emergency plumber in Andover, MA usually means something has gone wrong with water: a flooded cellar, a failed tank, a pipe that let go, or a drain that backed up. Our 24/7 dispatch line covers the town from the Lawrence side, roughly four miles from Town Hall.
Andover plumbing has a few features worth knowing before anyone opens a wall. The town publishes detailed water results, it is removing lead service lines, and it bans sump water from its sewer.
What the town's water report says about your pipes
Andover's Water and Sewer Division draws mostly from Haggetts Pond, with Fish Brook and the Merrimack River as supplements, and treats it at a plant on Lowell Street. Its 2023 report lists hardness at 38.5 mg/L, which the town calls soft, and a pH of 8.88.
Soft water tends to leave less scale than hard water, so a tank water heater may collect less crust. Sediment still builds at the bottom over time, though, so a flush and an anode check remain worth asking about. Our water heater repair calls are a good time to raise it.
The higher pH is there for corrosion control. If you see blue-green staining or pinhole leaks in copper, mention your water results on the call so the plumber can weigh them.
Lead lines: where Andover stands and what to ask
Under a consent order signed in April 2022, the town is removing lead service lines and investigating lines of unknown material. It took out 45 lead service lines in 2023. Lead at the 90th percentile measured 13.8 ppb that year, against a 15 ppb action level, in samples drawn from homes known to have lead lines or lead solder.
What that means for you is practical. Before a plumber replaces a water line or meter connection, ask the Water and Sewer Division at (978) 623-8700 what material the town has on record and where the town's responsibility ends. A leaking lead service is usually replaced, not patched, and the town's program may affect timing and cost. Our water line repair crews can work around that conversation.
Sump pumps and the sewer rule
Andover's sewer regulations prohibit rain water, sump pump water and surface runoff from entering the sanitary sewer. A sump that discharges into a floor drain or a sewer cleanout breaks that rule, and the fix is a discharge line that goes outdoors.
A good setup also has an accessible check valve on the discharge piping, as the state plumbing code requires for ejector and sump discharge. Our sump pump work covers replacement, check valves and battery backup. If water keeps returning, a basement water control review looks at the grading and drains around the foundation.
Cellar taking on water?
Give dispatch the room and how fast it is rising. We will help you decide what to power down while a plumber is arranged.
Sewer or septic: know which your house has
Most Andover wastewater goes to the Greater Lawrence Sanitary District, but the town's housing plan says some properties use on-site septic systems. Which streets are sewered is not something we assume.
The answer changes the call. A sewered house with a blocked lateral needs sewer line repair or cleaning. A septic house with the same symptoms may have a full tank or failed leach field, which is a different trade. Ask the town or look for a cleanout and a tank lid before you describe the problem.
Sewered homes and septic homes, side by side
Same gurgling toilet, two different next steps.
Connected to town sewer
- Blockage is often in the lateral or the main.
- A camera shows roots, breaks or bellies.
- The owner is responsible for the lateral.
- Sump water cannot be piped into it.
On a septic system
- Check the tank level and last pumping date.
- Slow drains everywhere can mean a full tank.
- Wet ground over the field is a warning sign.
- Pumping and field repair are a separate specialty.
If you are unsure, say so. We would rather sort it out by phone than send the wrong equipment.
Older houses in Shawsheen Village and beyond
Over a third of Andover's housing, about 37 percent, was built before 1960. Shawsheen Village was laid out in 1919 and the early 1920s, so some buildings there are a century old.
That age means a plumber may find mixed materials, from old iron drains to later copper and plastic repairs. Ask for a camera look at any drain you plan to keep, and expect part-replacement discussions rather than single fixes. A repiping conversation is reasonable when the same house has leaks in more than one spot.
Utility questions and who answers them
Some answers come from the town, not a plumber.
| Question | Who to ask | Line |
|---|---|---|
| Water quality or lead line record | Water and Sewer Division | (978) 623-8700 |
| Main break or street-side water loss | DPW emergency | 978-623-3500 |
| Permit for plumbing or gas work | Plumbing Inspection, 36 Bartlet St | (978) 623-8603 |
| Gas smell | Leave, call 911, then the gas company | Eversource |
| House-side leak, backup, dead tank | Our dispatch line | 24/7 |
Plumbing and gas work that is replaced or repaired needs a permit from the local inspector.
Gas smells and the 2018 memory
On September 13, 2018, a gas overpressurization in the Merrimack Valley led Andover crews to put out 38 fires and respond to 17 more gas leaks. Many residents still treat any odor seriously, and they are right to.
If you smell gas, leave the house, call 911 from outside, avoid switches, then call the gas company. Eversource now operates the former Columbia Gas system. Once the gas is cleared, we can look at the piping or appliance.
While Dispatch Gets a Plumber to You
Andover's utilities offer a few extra levers worth knowing.
Find the curb stop and meter valve
Shutting the valve at the meter stops the house supply. Ask the Water and Sewer Division before touching the curb stop in the yard.
Unplug the sump, not the panel
If a flooded sump is near power, disconnect only the pump cord when the floor is dry. Leave the breaker alone if you are standing in water.
Stop sending water down
No dishwasher, no laundry, no flushing while a drain is backing up. Every gallon you add finds the lowest opening.
Write down what you saw
Note the time, which fixtures were involved and any smell or discoloration. Dispatch and your insurer will both ask.

Andover water and plumbing FAQ

The town's 2023 report lists hardness at 38.5 mg/L, which it describes as soft. That usually means scale is a smaller concern than in hard-water towns. Test your own tap if you notice spots or buildup before buying any equipment.
Call the town's Water and Sewer Division at (978) 623-8700 and ask what material is on record for your address. A plumber can also look at the pipe where it enters the house, but town records tell you about the street side.
No. Andover's sewer regulations bar sump pump water from the sanitary sewer. The pump should discharge outdoors through a line with a check valve, and we can reroute an existing pipe that does not.
Yes, some properties use on-site septic. The town's housing plan says so without listing streets. Check with the town before assuming you are on sewer, especially if your house sits well away from a main road.
