Common questions
Plumbing Questions DC & Maryland Homeowners Ask
How often should I have my drains cleaned in a DC home?
For most single-family homes in Washington DC and Maryland, an annual drain cleaning is a reasonable baseline — more frequently if you notice recurring slow drains or have older cast iron pipes common in DC rowhouses. High-use kitchens and multi-tenant properties benefit from more frequent maintenance.
What are the signs I need a water heater replacement?
Key signs include a unit over 10–12 years old, rusty or discolored hot water, popping or rumbling noises during heating, visible corrosion around the tank or connections, and inconsistent hot water supply. A licensed plumber can assess whether repair or replacement makes more financial sense based on the unit's age and condition.
How do I know if I have a slab leak in my DC home?
Common signs of a slab leak include unexplained increases in your water bill, warm or wet spots on the floor, the sound of running water when all fixtures are off, and cracks developing in your foundation or flooring. Slab leaks require professional leak detection equipment to locate accurately before repair.
What causes low water pressure in Washington DC homes?
Low water pressure in DC and Maryland homes is commonly caused by mineral buildup inside older galvanized pipes, a failing pressure regulator, partially closed shut-off valves, or a supply line leak. DC's older housing stock is especially prone to pressure issues from internal pipe corrosion over time.
What plumbing maintenance should DC homeowners do before winter?
Before DC's winter months, homeowners should insulate exposed pipes in unheated spaces, disconnect and drain outdoor hose bibs, confirm their main shut-off valve operates correctly, and have the water heater inspected if it hasn't been serviced recently.
