Common Plumbing Problems in Maryland Homes

Root Cause

Acidic well water (low pH) slowly corrodes copper pipes from the inside, creating pinhole leaks that appear in multiple locations over time.

Warning Signs

• • Multiple small leaks in different locations
• • Blue-green staining on copper pipes and fixtures
• • Water damage in walls or ceilings with no obvious source
• • Unexplained water bill increase

The Right Solution

An acid neutralizer corrects the pH of the well water, stopping the corrosion. Without addressing the water chemistry, the leaks will continue regardless of how many times the pipes are repaired.

Root Cause

A failed pressure tank bladder causes the well pump to turn on and off every few seconds — sometimes hundreds of times per day. This destroys the pump motor within weeks to months.

Warning Signs

• • Pump turns on and off rapidly when water is running
• • Pressure fluctuates noticeably at fixtures
• • Pump runs constantly or very frequently
• • Water pressure drops suddenly then recovers

The Right Solution

Replace the pressure tank immediately. Short-cycling is the leading cause of premature well pump failure in Maryland. A new pressure tank is far less expensive than a well pump replacement.

Root Cause

Hard water deposits scale (calcium carbonate) inside the water heater tank and on heating elements. Scale acts as insulation, forcing the heater to work harder and accelerating corrosion.

Warning Signs

• • Rumbling or popping sounds from the water heater
• • Reduced hot water capacity
• • Higher energy bills
• • Water heater failing before 10 years of age

The Right Solution

Address the water hardness with a water softener before replacing the water heater. Without treating the water, a new water heater will fail just as quickly. Annual sediment flushing extends tank life.

Root Cause

Drains that back up repeatedly after snaking have an underlying problem that snaking does not solve — root intrusion, grease buildup on pipe walls, or a partial pipe collapse.

Warning Signs

• • Drain backs up within days or weeks of being snaked
• • Multiple drains backing up simultaneously
• • Gurgling sounds from drains
• • Sewage odor inside the home

The Right Solution

A sewer camera inspection identifies the exact cause. Hydro jetting scours the pipe walls clean for grease and root tendrils. Pipe repair or replacement is needed for collapsed sections.

Root Cause

Iron in well water — extremely common in Calvert County and Anne Arundel County — stains everything it contacts: sinks, tubs, toilets, laundry, dishes, and irrigation systems.

Warning Signs

• • Orange or rust-colored stains on fixtures and laundry
• • Orange slime in toilet tank (iron bacteria)
• • Metallic taste in water
• • Staining that returns quickly after cleaning

The Right Solution

A comprehensive water test determines the iron type and concentration. An iron filter, oxidation system, or combination treatment removes the iron before it reaches your fixtures. The water softener must be installed after the iron filter.

Root Cause

Pipes running under the concrete foundation develop leaks — most commonly from acidic water corroding copper pipes, or from soil movement stressing pipe joints.

Warning Signs

• • Warm spot on the floor (hot water line leak)
• • Sound of running water when everything is off
• • Unexplained water bill increase
• • Water seeping up through the floor or foundation

The Right Solution

Non-invasive leak detection locates the exact position of the leak without unnecessary demolition. Repair options include direct access repair, pipe rerouting, or epoxy pipe lining depending on the pipe condition.

Root Cause

Tree and shrub roots seek out moisture and nutrients in sewer lines, entering through joints and cracks. Once inside, roots grow rapidly and create blockages.

Warning Signs

• • Slow drains throughout the house
• • Backups that worsen during or after rain
• • Gurgling sounds from toilets
• • Sewage odor in the yard

The Right Solution

A sewer camera inspection confirms root intrusion and locates the affected section. Hydro jetting removes the roots. Depending on pipe condition, repair or replacement may be needed to prevent recurrence.

Root Cause

Low pressure throughout the house on a well system is usually caused by a failing pump, a waterlogged pressure tank, a pressure switch set too low, or a significant leak.

Warning Signs

• • Weak flow at all fixtures simultaneously
• • Pressure that drops steadily when water is running
• • Pressure gauge reading below 40 PSI
• • Pump running constantly

The Right Solution

A pressure gauge at the pressure tank tells you whether the system is maintaining pressure. If pressure drops when water runs, the pump is likely failing. If pressure is low even when no water is running, the pressure switch or tank may be the issue.
