Sewage Pump Service in Gaithersburg
A sewage pump moves waste, not water. It lifts everything a building's drains produce up to the level of the sewer main, and it exists because gravity does not work uphill.
Mallick installs, replaces, repairs and maintains sewage pumps for homes and businesses across Gaithersburg and Maryland — the pump itself, the basin, the float and the discharge line, which is the whole of what fails.

The float and basin are checked before recommending pump replacement.
Sized to the fixtures it serves, so it is not cycling itself to pieces.
Residential and commercial, including below-grade units and lower-level baths.
Worth Knowing
A sewage pump is not a sump pump, and the two are confused constantly. A sump pump moves clean groundwater out of a pit to keep a basement dry. A sewage pump moves wastewater and solids from fixtures up to the sewer line.
They fail differently, they are serviced differently, and one cannot do the other's job. If your basement floods in heavy rain, you are looking for a sump pump; if a basement bathroom backs up, it is the sewage pump.
Installation plan
The need is structural rather than optional. When a fixture sits below the level of the sewer main — a basement bathroom, a lower-level laundry, a below-grade commercial unit — gravity cannot carry the waste out, so it has to be lifted.
The pump works with a holding basin or tank that collects the waste and prevents buildup, and discharges when the level calls for it. Sizing that basin and pump to the fixtures they serve is what stops the system short-cycling itself to death.
We confirm which machine you actually have. Sewage pump and sump pump present similarly from the basement and need different work.
Pump, basin, float and discharge line checked together — the pump is often innocent and the float is not.
Sizing checked against the fixtures served, because an undersized pump short-cycles itself to an early death.
Tested under load, and the work warrantied — a year on installations, thirty days on repairs.
Worth Knowing
The failure mode is unpleasant enough to justify maintenance. A sewage pump that stops does not simply fail to work — the basin fills and wastewater backs up into the lowest fixture in the building.
Most failures give notice: the pump runs longer than it used to, cycles more often, or starts making a different noise. Those are worth a call. So is anything flushed that should not have been, because sewage pumps are destroyed by wipes and cloth more often than by age.
Why Mallick
WSSC-licensed and insured crews, and warranties in writing: one year on installations, 30 days on repairs. The same standard whether it is a sewage pump call at 2pm or a burst line at 2am.

“Eric and Nick did a wonderful job.”
Very thorough and provided detailed explanation of what was needed to get our garbage disposal up and running.
Abbas and Koli were great technicians.
Quickly diagnosed the issue, thoroughly explained everything, and gave me a few options to move forward. I've had great experiences working with Mallick, highly recommend.
Abbas came to our house for an emergency repair on a Saturday.
He was courteous and kind, he didn’t rush, and he worked hard to fix our problem and thoroughly investigate. It was hard to find a plumber who could do this on a Saturday at the last minute, and we appreciated Mallick’s and Abbas’s willingness.
Abbas Rahimiari was exceptionally professional, looking at our two plumbing problems, describing the underlying issues, fixing one immediately and explaining options on the other. Courteous, clear and efficient. And knowledgeable.
I had a wonderful experience with Billy.
He was amazing and he was able to fix my issue with no concerns! 10/10! Thank you Billy.
Excellent service and support from William Clem and Malick Plumbing.
Had a pinhole leak in a water service line. Found and fixed the problem … thanks so much.
Roberto and Adelson were great to work with, efficient, and answered all questions. Top service and repair of water heater!
Fred and Luka were great!
They took the time to find the issue as well as helping me get opinions on future concerns as a new homeowner! Real experts and will work with them again!
Abbas and Koli were fantastic.
They quickly identified and resolved our issue, and did a check to ensure there were no other sleeping issues. They were a pleasure to work with, respectful, and kind.
I received great service from both Ikem and CJ today.
They quickly identified the leak and fixed the issue. They also did a great job replacing some valves that needed replacing. They were very experienced and efficient. I have used Mallick several times and have always been pleased with their service.
Abbas and Erick were professional, knowledgeable and kind.
They inspected and guided me to make safe choices with my range that had a gas leak.
Abbas and Bryan installed my new water heater.
There was a leak in my furnace and they fixed it also! The job was perfect. They had to install vents that were well done. They left no trace and the house was completely clean. The new water heater works like a charm. HIGHLY RECOMMEND this team and Mallick.
Kyle was so helpful in helping my husband and I fix the water pressure in our house. Kyle was very well versed and experienced, providing great options for future improvements to water filtering. I would highly recommend his services to anybody struggling with plumbing issues.

A sump pump removes clean groundwater from a pit to keep a basement dry. A sewage pump lifts wastewater and solids from fixtures below the sewer line up to it. They are different machines for different jobs, and one will not substitute for the other.
When a fixture sits below the level of the sewer main — a basement bathroom, a lower-level laundry room, or a below-grade commercial unit. Gravity cannot move waste uphill, so it has to be pumped. If your property is below the sewer line, you have one.
Running longer than it used to, cycling more frequently, unusual noise, or wastewater backing up into the lowest fixture. The backup is the late sign — the run time and the cycling are the early ones, and they are the point at which a repair is still small.
Wipes — including ones sold as flushable — cloth, sanitary products and grease. Sewage pumps are killed by what goes into them far more often than by age, and a pump that has been fed wipes will fail well before its rated life.
