Why Is Water Pressure So Low Around My Home?

faucet-drippingIf you discover a single faucet or shower head in your home has lost its normal water pressure, the reason is probably a buildup of silt in the aerator. There might be other reasons, but they’ll be connected to that specific tap.

But what’s going on if taps all around the house have experienced a drop in water pressure? That’s not a minor problem. Something bigger is occurring, and you’ll want to get to the bottom of it soon. In some situations, you’ll need to call a professional plumber in Corona, CA to investigate and fix the issue.

Below are a few of the possibilities for a house-wide water pressure drop.

A Municipal Problem

One of the first things we recommend you check is if the water pressure problem extends even farther than your house. See if your neighbors are dealing with the same troubles. If they are, then the source of the water pressure drop is the municipal water supply and will probably be fixed soon. You can call the utility company to learn more if the water pressure doesn’t improve.

Corrosion in the Water Main

The older the home, the higher chance that its water main is made from outdated material like galvanized steel. This metal corrodes with time, and eventually the corrosion layer inside the pipe will restrict water flow—and this means low water pressure everywhere. If your home was built before 1970, you may need to have our plumbers install a new water line. (Yes, the water line under your property is your responsibility, not the city’s.)

Massive Water Main Leak

Another problem with the water main that can create low water pressure is a massive break along the main allowing leaks. Check outside your house to see if water is seeping up from the ground or through cracks in the sidewalk. This will warn you of a water main break. Call for plumbing repair work right away.

Stuck Water Shut-Off Valve

Have you had any repairs done recently for your plumbing, or had to shut off the water to the house for any reason? If so, the shut-off valve for the water main may not be open all the way. You’ll find the shut-off valve located next to the water meter. Make sure that it is fully open.

Broken Water Pressure Regulator

Not all homes have a water pressure regulator. This device is installed in houses where water pressure from the municipal system is too high and threatens damage to the plumbing. The valve can malfunction like any mechanical device and lower the pressure too far. If you know where the regulator is, you can check to see if something has come loose on it. In most situations, you will need a professional plumber to replace the regulator with a new one.

Please don’t attempt any fixes to the plumbing more extensive than opening the shut-off valve. When you can’t figure out why you have low water pressure, call our licensed plumbers to diagnose and repair the problem.
