Trusted Local Plumbing Services in Douglas & Arapahoe Counties

You turn on the shower expecting a strong stream of water, and instead, you get something closer to a drizzle. Or maybe the kitchen faucet works fine until someone starts the washing machine, and suddenly there’s barely enough pressure to rinse a plate.

Low water pressure can be frustrating, but it can also tell you something important about your home’s plumbing system.

For homeowners in Greenwood Village, low water pressure can come from something as simple as a clogged faucet aerator or something more serious, such as a hidden leak or deteriorating pipe. Figuring out whether the problem affects one fixture or your entire house is usually the best place to start. Here’s what could be behind low water pressure in Greenwood Village, CO, and when it’s time to call a plumber.

First, Is the Low Water Pressure Everywhere?

Before assuming there’s a major plumbing problem, do a quick check around your house. Turn on faucets in the kitchen and bathrooms. Check the showers. Test both hot and cold water. If you have outdoor faucets, check those too.

What you find can help narrow down the problem. If only one faucet or shower has low pressure, the issue is probably located at that fixture. If the entire house has weak water pressure, the problem could involve your main water supply, pressure regulator, shutoff valve, or plumbing pipes.

It’s also worth noticing whether the problem happened suddenly or has gradually gotten worse. A sudden pressure drop can point to a leak or valve problem, while gradual changes may be caused by mineral buildup or aging plumbing.

1. Your Faucet Aerator or Showerhead Is Clogged

If low pressure is limited to one sink or shower, start with the fixture itself. Faucet aerators and showerheads have small openings that can become clogged with sediment and mineral deposits over time. When those openings become restricted, less water can pass through.

Unscrew the aerator or showerhead and inspect it for buildup. Depending on the fixture, cleaning it may restore normal water flow.

If every other fixture in the house has good pressure, there’s a good chance the problem is local rather than a larger plumbing issue.

2. A Shutoff Valve Isn’t Fully Open

Your home’s plumbing system has valves that control water flow. If the main shutoff valve isn’t completely open, it can restrict water throughout the house.

This sometimes happens after plumbing work. A valve may have been closed during a repair and not reopened completely afterward. Before adjusting anything, make sure you know which valve you’re dealing with. Older valves can become difficult to operate, and forcing a corroded or damaged valve can create a leak.

If you’re unsure, a professional plumber can inspect the valves and determine whether they’re contributing to the pressure problem.

3. Your Pressure Regulator May Be Failing

Some homes have a pressure-reducing valve, commonly called a pressure regulator. Its job is to keep incoming water pressure at a safe and consistent level.

When the regulator begins to fail, you might notice water pressure that’s suddenly too low, too high, or inconsistent throughout the house. You usually can’t diagnose a failing pressure regulator just by looking at it. A plumber can test your home’s water pressure and determine whether the regulator needs adjustment or replacement.

4. You Could Have a Hidden Plumbing Leak

Low water pressure can sometimes signal a plumbing leak. If water is escaping somewhere in the plumbing system before it reaches your fixtures, you may notice weaker pressure throughout part or all of your home.

Other signs of a hidden leak can include:

• An unexplained increase in your water bill

• Damp spots on walls, ceilings, or floors

• Water stains or discoloration

• Musty odors

• The sound of running water when fixtures are off

• Unusually green or wet areas outside

• A water meter that continues moving when you’re not using water

A small pressure change doesn’t automatically mean you have a major leak, but low pressure combined with these warning signs is a good reason to schedule plumbing repair in Greenwood Village.

5. Older Pipes May Be Restricting Water Flow

Plumbing pipes don’t necessarily stay the same on the inside as they age. Depending on the material and condition of the pipes, corrosion and mineral buildup can gradually reduce the space available for water to travel through. You may still have water, but the flow at your faucets and showers becomes noticeably weaker.

This type of problem often develops slowly. You might not notice it immediately because the pressure decline happens over months or years.

If your home’s water pressure has gradually gotten worse and cleaning fixtures doesn’t help, a plumber may need to inspect your pipes.

In some cases, targeted pipe repair in Greenwood Village may solve the problem. In others, sections of older or deteriorated piping may eventually need replacement.

6. There Could Be a Problem With the Water Supply

Not every water pressure problem originates inside your house. Occasional changes can occur because of work on the municipal water system, neighborhood maintenance, or another temporary supply issue.

If your water pressure suddenly drops throughout the entire home, it can be helpful to find out whether your neighbors are experiencing the same thing. If several nearby homes have low pressure at the same time, the issue may be outside your property.

If your neighbors have normal water pressure and you don’t, the problem is more likely somewhere within your home’s plumbing system.

7. High Water Demand Can Make Pressure Seem Lower

Does your shower pressure drop whenever the dishwasher, washing machine, or another shower is running?

Using several water-consuming appliances and fixtures simultaneously can affect water flow, particularly if your plumbing system already has pressure or capacity issues. A slight change can be normal. A dramatic drop, however, may be worth investigating.

If taking a shower becomes nearly impossible whenever someone turns on another faucet, a plumber can measure the pressure and flow to determine what’s happening.

What Is Considered Normal Water Pressure?

Residential water pressure is commonly somewhere around 40 to 60 psi, although individual homes and water systems can vary.

Consistently low pressure can make everyday tasks frustrating. Pressure that’s too high isn’t necessarily better because excessive pressure can put unnecessary stress on pipes, fixtures, appliance connections, and valves.

Instead of simply trying to increase the pressure as much as possible, the goal should be consistent water pressure that’s appropriate for your home’s plumbing system.

A professional pressure test can give you a much clearer picture of what’s happening.

Why Is My Hot Water Pressure Low but Cold Water Is Fine?

This is an important clue. If you only experience low pressure when using hot water, the problem may be related to your water heater or hot-water plumbing rather than the home’s main water supply.

Sediment, a partially closed valve, or another restriction on the hot-water side of the system could affect flow. If both hot and cold water have low pressure, the issue is more likely to involve the fixture itself or a larger part of your plumbing system.

Can I Fix Low Water Pressure Myself?

It depends on the cause. Cleaning a clogged faucet aerator or showerhead is a reasonable place to start. You can also check whether the problem affects one fixture or your entire home and whether both hot and cold water are affected.

Beyond those basic troubleshooting steps, diagnosing low water pressure can become more complicated.

Call a professional if:

• Water pressure suddenly drops throughout your home

• The problem continues after cleaning fixtures

• You suspect a hidden leak

• Your water bill has unexpectedly increased

• You see signs of water damage

• Pressure fluctuates significantly

• Your pipes are older or showing signs of corrosion

• Only the hot-water supply has poor pressure

• You aren’t sure whether your pressure regulator is working correctly

A plumber can test the pressure and inspect the system rather than guessing and replacing parts that may not be causing the problem.

Don’t Ignore a Sudden Change in Water Pressure

Low water pressure isn’t always an emergency. Sometimes the fix really is as simple as cleaning a showerhead.

But when water pressure suddenly changes or keeps getting worse, it’s worth figuring out why.

A hidden leak, failing pressure regulator, restricted valve, or deteriorating pipe can turn a minor inconvenience into a larger plumbing repair if the underlying problem isn’t addressed.
