Why Is My Water Pressure So Low?

There’s nothing worse than stepping into the shower expecting a strong stream of water, only to get a sad little trickle. Low water pressure is one of the most common complaints we hear from homeowners, and it can be caused by all kinds of things, some simple and some serious.

At SteadyFlo Drain Cleaning & Plumbing, we have tracked down low pressure issues in homes across Middle Tennessee for years. Here’s a look at the most common causes and what you can do about them.

Is It One Fixture or the Whole House?

Before you call a plumber, do a quick check. Is the pressure low at just one faucet, or is it weak everywhere? This one question tells you a lot about what’s going on.

If it’s just one spot, the problem is local. If it’s the whole house, the issue is bigger and likely involves your main line or water supply.

Common Causes of Low Water Pressure

Clogged Aerators or Showerheads

This is the easiest fix on the list. Aerators are the little screens on the end of your faucets, and over time, they collect minerals and debris. Unscrew the aerator, soak it in vinegar overnight, and rinse it out. Same goes for showerheads. You’d be surprised how often this fixes the problem in just a few minutes.

Mineral Buildup in Pipes

Tennessee water tends to be on the harder side, which means more minerals flowing through your pipes. Over the years, those minerals build up inside the pipes and narrow the path for water to flow.

If your home is older or has galvanized steel pipes, this is a very common cause. The buildup is gradual, so you might not notice it until the pressure gets really bad.

A Hidden Leak

A leak somewhere in your plumbing can rob you of water pressure throughout the house. You might not even see the leak if it’s behind a wall or under the slab. Watch for unexplained spots on ceilings or walls, musty smells, or a sudden jump in your water bill.

If you suspect a leak, give us a call right away. Catching it early can save you from major damage.

Pressure Regulator Problems

Most homes have a pressure regulator that controls how much water pressure comes into the house. When it fails, your pressure can drop (or spike too high). If your pressure has changed suddenly and you can’t figure out why, a faulty regulator might be the culprit.

Issues With the Main Water Line

If your main water line is partially blocked, cracked, or damaged by tree roots, your whole house will feel it. This is more common in older homes with aging pipes. Our team can perform an inspection to see exactly what’s happening underground.

Problems With Your Water Heater

If the pressure is only low when you turn on the hot water, your water heater might be the issue. Sediment buildup inside the tank can block the hot water outlet and slow the flow. Flushing the tank once a year helps prevent this.

Issues With the Municipal Supply

Sometimes the problem isn’t even at your house. If your neighbors are dealing with low pressure too, the issue is on the city’s end. A quick call to your water provider can confirm whether there’s a known issue in your area.

Simple Things to Try First

Before you call a plumber, run through these quick checks:

• Clean your aerators and showerheads
• Make sure your main shutoff valve is fully open
• Check your water meter valve to make sure it’s open all the way
• Ask your neighbors if they are dealing with the same issue
• Look around for any visible leaks or wet spots

If none of these fix the problem, it’s time to bring in the pros.

When to Call SteadyFlo

If you have tried the basics and your water pressure is still bad, our licensed plumbers can dig deeper to find the real cause. We’ll inspect your water lines, check your pressure regulator, and figure out exactly what’s holding you back.

Don’t put up with weak showers and slow-filling tubs. A few minutes with our team can have your water flowing the way it should.

FAQs

What is normal water pressure for a home?

Most homes run between 40 and 60 PSI. If yours is much lower, something is off. If it’s much higher, that’s also a problem since high pressure wears out fixtures faster.

Can hard water cause low water pressure?

Yes, over time. Hard water leaves mineral deposits inside your pipes and fixtures, which can narrow the flow path and reduce pressure. A water softener can help slow the buildup.

How do I know if my pressure regulator is bad?

Sudden changes in water pressure, either too low or too high, are the most common signs. Strange noises from the pipes can also point to a regulator issue. Our team can test it for you.

Will fixing low water pressure raise my water bill?

Not usually. In fact, fixing a leak that’s causing low pressure will often lower your bill. Boosting pressure back to normal levels is more about comfort and convenience than usage.
