Why Your Houston Home Has Low Water Pressure (And How to Fix It)
Low water pressure is a frustrating problem that affects thousands of Houston and Cypress homeowners every year. Whether it’s happening at a single faucet or the entire home, the issue usually traces back to a few common causes.
Here’s what may be happening and how a professional plumber can help.
1. Hard Water Build-Up in Pipes
Houston is known for hard water. Over time, minerals restrict water flow in your plumbing system, causing noticeable pressure loss.
2. Failing or Old Pressure Regulator
If your water pressure suddenly drops overnight, your pressure-reducing valve (PRV) may be failing.
3. Partially Closed Main Shutoff Valve
After repairs or maintenance, the main valve may not be fully open, reducing pressure throughout the home.
4. Leaks in the Water Line
Even a small leak reduces water pressure. Look for damp spots, unusually high water bills, or sounds of running water.
5. Clogged Aerators or Showerheads
Mineral buildup in aerators is another common cause of low pressure.
