Know where the property-line cleanout is
The City of Annapolis repeatedly emphasizes the property-line cleanout because it provides access to the sewer lateral and becomes important during a blockage. Do not wait for sewage to be on the floor before trying to find it. Keep the cleanout visible and accessible.
Keep grease, fats and oils out of drains
Grease can cool and accumulate inside pipes, trapping other debris and narrowing flow. Annapolis and Anne Arundel County both warn against sending fats, oils and grease into the sewer system. Wiping pans and disposing of grease in the trash is safer for household plumbing and the public collection system.
Do not trust the word “flushable” on wipes
Anne Arundel County explicitly warns that wipes and hygiene products should not be flushed even when labeled flushable. Toilets are designed for human waste and toilet paper; other products can contribute to private blockages and public sewer obstructions.
Pay attention to repeated slow drains and gurgling
One slow sink may be a local fixture issue. Several slow fixtures, recurring toilet problems or gurgling at low drains can be early signs of a downstream restriction. Address patterns before wastewater has a chance to return through the lowest opening.
Understand backwater-valve protection
Annapolis recommends that property owners use a registered plumber to install and maintain a backwater valve on the lowest drain line where required. A backwater valve is designed to help stop reverse flow, but it needs correct installation and maintenance.
Keep roots and landscaping in mind
Tree roots can enter damaged or vulnerable sewer laterals. Annapolis prevention guidance cautions against planting trees near sewer lines. If a property has recurring lateral problems, a plumber can advise whether inspection or repair is warranted.
Do not connect stormwater where it does not belong
Sump pumps and storm drainage should not be improperly connected to sanitary sewers. Excess inflow can overload wastewater systems and contributes to broader collection-system problems.
Have a response plan before the next event
Store the plumber, utility and cleanup contacts you would need. Know whether the property is inside City of Annapolis utility jurisdiction, elsewhere in Anne Arundel County, or on septic. Quick source control and clear information reduce confusion during a backup.
A simple prevention checklist for Annapolis-area properties
Know where the sewer cleanout is before an emergency. Keep grease and cooking oil out of drains. Flush only human waste and toilet paper. Investigate recurring gurgling or several slow fixtures instead of treating each one as an isolated nuisance. Keep roots and landscaping away from vulnerable sewer lines where possible. Ask a plumber about backwater protection and private-lateral condition when the property has a history of backups. If the building uses septic, maintain the septic system on its own schedule rather than applying municipal-sewer advice to it. Prevention is strongest when the property owner understands the exact wastewater system serving the address.
Common mistake: waiting for a full backup before maintaining the system
Recurring gurgling, multiple slow drains and repeated toilet issues are early warning patterns worth investigating before wastewater returns through the lowest fixture.

Questions about how to reduce the risk of sewage backups in annapolis
What should never be flushed?
Wipes, hygiene products, diapers and other foreign materials should stay out of toilets even when a package says “flushable.”
Why is grease a sewer problem?
Fats, oils and grease can accumulate inside pipes, restrict flow and trap debris.
What is a sewer cleanout?
It is an access point to the sewer lateral, commonly located near the property line in Annapolis.
Can prevention guarantee there will never be a backup?
No. Public-system failures, damage, roots, extreme flow and other causes can still occur, but good maintenance and proper disposal habits can reduce avoidable risk.
