Why Is My Water Pressure Low?

DPA Admin • August 11, 2025

Have you ever turned on your faucet and wondered, “Why is my water pressure so low”?

This is one of the most common issues homeowners face, be it in Houston or Lafayette. So common that low water pressure and leaks have become one of the primary reasons for most 311 calls in Houston. 

From seeping showers to a slow-filling washing machine, low water pressure is annoying. But should you call in a plumber for low water pressure? Read the following blog to find the answer.

5 Common Causes of Low Water Pressure in the House

1. Clogged Pipes:

Flowing water can cause the accumulation of debris and chemicals in pipes, slowing down the water pressure.


2. Corroded Plumbing:

Older Houston homes still have galvanized water pipes. Over the years, these can lead to corrosion, restricting water flow.


3. Malfunctioning Pressure Regulator:

Minutely check the pressure regulator of your home. A fault in the regulator can cause sudden drops in water pressure.


4. Sneaky Leaks:

As per recent findings, Houston lost about 32 billion gallons of water due to small leaks. A small leak underground or behind a wall not only reduces pressure but also raises your water bill.


5. Water Heater Trouble:

Low hot water pressure? Your water heater could be to blame. Sediment buildup in the tank may be affecting your hot water flow. If this is the issue, try reaching out to Alltex Plumbing for water heater repair in Houston.

When to Call Alltex Plumbing for Reduced Water Pressure?

If you have been experiencing low water pressure around the house, be it in the kitchen or the bathroom, you will need professional help. That is where All-Tex Boiler and Plumbing Services comes to the rescue. Our licensed experts serve in Houston and Lafayette, providing fast and efficient solutions. 


How Do We Diagnose Low Water Pressure? 

To diagnose low water pressure, our plumbers follow a step-by-step method: 

  1. First, we check the main water valve to make sure it is fully open, since a partially closed valve can lower pressure. 
  2. Next, we examine fixtures to see if the problem is limited to a specific area, like a clogged faucet or showerhead. 
  3. We then evaluate the water pressure with a gauge to measure the flow accurately. 
  4. After that, we look at the pipes for leaks, corrosion, or blockages that could disrupt water flow. 

If low water pressure comes from external issues like problems with the municipal water supply, we can help you take the right steps to fix it. Our team knows how to assess and solve the problem, so your water pressure can be restored effectively.
