Low Water Pressure in Buffalo, NY Homes: Causes & When Repiping Is Needed
What Causes It & When Repiping May Be the Solution
Low water pressure is one of the most common plumbing complaints in older Buffalo homes.
If your house was built before 1980 and you’ve noticed declining pressure over time, aging plumbing may be the cause.
Many homes throughout Buffalo — especially in neighborhoods like Elmwood Village, North Buffalo, and South Buffalo — still contain original galvanized or aging copper pipes that are now 50–100 years old.

What Causes Low Water Pressure in Older Buffalo Homes?
Several factors can reduce water pressure, but in older properties the most common causes include aging pipe systems.
1. Internal Corrosion in Galvanized Pipes
Galvanized steel pipes corrode from the inside out. Over decades, rust buildup narrows the pipe’s interior diameter.
This restriction reduces water flow and results in:
• Weak shower pressure
• Slow-filling sinks or tubs
• Pressure that drops when multiple fixtures run

2. Aging Copper Plumbing
Older copper systems can develop mineral buildup or internal scaling over time. In some cases, pinhole leaks or partial blockages may reduce consistent water delivery.
If your home was built in the 1950s–1970s and still has original copper lines, pressure loss may be tied to system aging.

3. Buffalo’s Freeze–Thaw Stress
Buffalo winters place stress on plumbing systems. Freeze events and repeated expansion can weaken joints and create minor internal damage that restricts flow over time.
Homes that have experienced previous freeze repairs may have pressure inconsistencies as a result.
4. Hidden Leaks
In some cases, low pressure may signal a hidden leak inside walls, ceilings, or under slab foundations.

When Is Repiping the Right Solution?
Not every pressure issue requires full replacement. However, repiping may be recommended if:
• Your home is over 40 years old
• Pressure has declined gradually over time
• Multiple leaks have occurred
• Pipes are original galvanized
• Copper system is 50+ years old
Full repiping removes internal corrosion and restores proper water flow throughout the home.

Can a Pressure Booster Fix the Problem?
Some homeowners consider installing a pressure booster system.
While boosters can increase force, they do not remove internal corrosion or pipe deterioration.
If aging plumbing is restricting flow, boosting pressure may actually place additional stress on weakened pipes.
