Why Is My Water Pressure So Low?

You’re expecting a long, steamy shower, but instead are met with an unsatisfying trickle of water. Or perhaps you’re trying to wash dishes, but you can’t get enough water pressure to effectively rinse them. Whatever the exact problem, low water pressure can be a pain. The following five reasons can explain water pressure problems, and often require expert assistance from a plumber.

Your home’s pressure regulator is failing. Some homes have a pressure regulator, which protects pipes against damage by maintaining a proper water flow. If the regulator fails, you might notice a sudden spike or decrease of water pressure in your home.

A valve is partially closed. Check both your water main shut-off valve, and the water meter valve, to ensure that they are both fully open. These valves can’t exactly close themselves, but if you’ve recently had work done to your home, or have spunky curious children afoot, they can be accidentally closed. We’ve seen stranger things!

Clogged fixtures. If the pressure problem seems localized to just one fixture, build-up inside the aerator could be the culprit. There might also be a clog in the line leading directly to that fixture. You can try soaking the nozzle in a vinegar-water solution. If that doesn’t work, call a plumber to have the line checked.

Your water heater is malfunctioning. If the low pressure problem seems to only affect your hot water supply, the problem might be originate with your water heater. Make sure the shut-off valve to the tank is fully open, and then call a plumber for help if that doesn’t fix the problem.

Your pipes are old and corroded. Over time, old pipes can become corroded and filled with scale. The accumulating build-up can close off the water flow, until you’re left with just a trickle of water from your fixtures. You might suspect this problem if your home is older, and you’ve noticed a gradual reduction in water pressure rather than a sudden onset of the problem.

Troubleshooting might lead you to suspect one or more of these situations, but to be sure, call our plumbing service for an expert diagnosis. Then we’ll help you correct the problem if it isn’t something simple that you can do yourself.
