8 Reasons Behind Your Home’s Low Water Pressure, Part 1

We’ve all experienced blocked drains and pipes severe enough to require the services of a plumber. But what if the problem isn’t with the water draining but with the volume of water that is really flowing out? In-home water pressure is typically between 40 and 45 pounds per square inch (or PSI). If you’re experiencing low water pressure, your pressure has likely dropped below this level.

American households consume 300 gallons of water per day on average, between bathing, running the dishwasher, and flushing the toilet. We rarely consider where the water originates from or how it exits our faucets. When the water pressure dips, most of us don’t know where to look.

We’re here to discuss eight potential reasons for low water pressure, so you know what to do and, if required, who to call. Continue reading to discover why!

1. Your water supplier is experiencing problems

Ask around before you start twisting valves and pounding on pipes. If your neighbors are experiencing similar problems, likely, your low water pressure is not caused by something in your own home.

Inquire with your water supplier to see whether they are aware of and working on a problem with their water supply. If it’s something that they’re working on, you’ll have to wait a little longer.

2. Your City Has Changed Its Regulations

You agreed to specific regulations when you signed onto the city’s water supply. These regulations are often determined by the amount of water that passes through a given area on average and the amount of infrastructure the city has to deal with it.

If the city’s infrastructure changes or grows, the regulations may change as well. If the city wants to expand its water supply, it’s likely to invest in bigger pipes, reservoirs, and processing facilities. The city may also raise the water pressure for several reasons, which can affect how much water is available to your home.

3. You Have a Leak in Your Water Supply

A water leak can be a small problem, or it can be gargantuan. The leak might be in your water supply pipes or in the water supply pipes of your neighbor. If the leak is anywhere along the water supply line, you might notice a drop in water pressure.

The larger the leak, the more noticeable the effects are. A tiny leak might cause a pressure drop that you can’t even feel; a significant leak can cause the water pressure to plummet to almost nothing, hampering your ability to get clean water at all.

4. You Have Old Pipes

Old pipes are usually a homeowner’s biggest water pressure problem. If your pipes are old and the water pressure is relatively low, then you might have to get ready to upgrade.

A few signs of old pipes are:

  • Rust, rust, and more rust
  • Peeling drywall and paint where the pipes are located
  • Pipes that are discolored
  • Pipes that make strange noises
  • Pipes that look like they’re about to burst through your wall

The best way to tell whether you have old pipes is to check the age of the pipes in your home. If the pipes are at least 50 years old, they might be old enough to cause problems.


The culprit behind low water pressure in your home could be any one of these. Knowing which one is the problem will help you know who to call. Fixing low water pressure problems requires a little elbow grease and a little know-how. If you’re unsure where to start or what to do, call a plumber and let them do the dirty work.
