Why You're Losing Water Pressure and What You Need to Know

When water pressure in your home drops, whether in a shower, sink, or outdoor spigot, it’s not always just an inconvenience. In coastal-bend and southern Texas homes, even small water-flow issues can point to bigger plumbing concerns: mineral buildup, pipe corrosion from salty air, hidden leaks, or pressure regulation failures. These problems can get worse over time, affecting multiple fixtures, increasing water bills, or even causing water damage.

At Aim Plumbing Services LLC, we’ve seen many of these issues first-hand across Corpus Christi, Portland, Beeville, Ingleside, Woodsboro and surrounding communities. Early detection and swift action help avoid costly repairs down the road.

Common Causes of Low Water Pressure

• Mineral & Sediment Buildup in Fixtures

Hard water and mineral-rich coastal supply water can leave deposits inside faucet aerators, shower heads, or inside piping over time. That buildup narrows the water path and reduces flow, often gradually, so homeowners don’t notice until pressure is significantly lowered.

Homeowner check-point: Remove and inspect aerators and showerheads for mineral crusting, discoloration, or scale. If clogged, clean or replace the fixture. If multiple fixtures are affected, you may need professional inspection.

• Pipe Corrosion or Aging Plumbing Lines

Corrosion, accelerated by salt air and coastal humidity, can narrow or damage internal plumbing over time, especially in older homes. Even if pipes look fine on the outside, interior corrosion may impede water flow.

• Hidden or Underground Leaks

Leaks inside walls, under slabs, or underground don’t always show visible water spots, but they can sap water flow. If water is disappearing somewhere in the system, pressure can drop. Slab leaks or underground leaks (especially common in coastal-bend neighborhoods) require professional leak detection and repair. 

• Pressure Regulator or Shut-off Valve Issues

Sometimes the source isn’t the pipes themselves but pressure regulators, valves, or municipal supply fluctuations. A partially closed main shut-off, a failing pressure-reducing valve (PRV), or inconsistent city water pressure can all lead to weak flow.

Warning Signs That It’s Time to Call a Licensed Plumber Instead of DIY

If you notice any of the following, it’s time to reach out to Aim Plumbing Services:

• Water pressure is weak across multiple faucets, showers, or outdoor hoses (not just one fixture)
• Sudden drop in water pressure after heavy rain, storms, or seasonal shifts
• Discolored, rusty, or metallic-tasting water, possible sign of internal pipe corrosion
• Consistently higher water bills without change in household usage (could signal leaks)
• Visible signs of dampness, mold, or foundation settlement, possibly due to hidden leaks under slab or behind walls
• Your home is older, with cast-iron or galvanized plumbing, age + coastal environment makes pipes more vulnerable

When these signs arise, delaying repair can lead to bigger issues, leaks, pipe bursts, water damage to walls/ flooring, and increased repair costs.
