Why Is My Home Water Pressure Low?

Mar 08, 2021

What does it mean when your shower, faucet, or entire home starts producing low water pressure? Unfortunately, dropping water pressure is often a sign of an issue somewhere in your plumbing system. Not only can low water pressure make showers less comfortable, but it can also reduce the effectiveness of your appliances. The plumbers at Newcomb and Company are here with insight. Here is a look at five reasons why your water pressure may be low (and what you can do about it).

Water Pressure Issue 1: Water Leaks

When water is leaking in your home, it will direct some of the water flow away from your fixtures. This might be a gradual leak or a sudden loss in water & pressure. Not only does this create low water pressure, but it also presents water damage risks, water waste, higher bills, and—of course—the task of finding and repairing the source of the leak.

How do you know when you have a water leak? Keep an eye out for standing water, water stains, and the sounds of leaking water. You should also keep a close eye on your water bill for unusual spikes in usage. If you suspect you have a water leak, contact an expert as soon as possible. Early detection can help minimize costs and damages. Here is our guide on what to do when you discover a water leak in your home. Thankfully, fixing the water leak at its source will restore your water pressure.

Water Pressure Issue 2: Water Pressure Regulator Valve

Most homes are equipped with a water pressure regulator valve (also called a PRV or pressure-reducing valve). As the name suggests, this device regulates your water pressure. Regulator valves keep your home within local water pressure limits—often between 60-80 PSI.

These water pressure regulations are essential. Your local water supply may be up to 150+ PSI to provide adequate water to fire hydrants and other necessary installations. However, this level of pressure would be incredibly turbulent and destructive within your residential pipes. Pressure-reducing valves prevent this plumbing damage and water waste while keeping your building up to city standards.

If your valve is set far beneath your area’s pressure regulation limits, it could be minimizing your water pressure. In this case, a plumber can improve your home water pressure by simply adjusting the regulator valve. Similarly, when your regulator valve reaches the end of its lifespan, it may begin limiting your water distribution. In this case, you will need a valve replacement to restore your water pressure.

Water Pressure Issue 3: Shower Head Troubles

New and efficient showerheads are designed to promote high water pressure. If you are dealing with an old showerhead, you may need a replacement to boost your water pressure and comfort. You might also consider adjusting your showerhead settings until you find one that is compatible with your preferences.

Water Pressure Issue 4: High Water Demand

Simultaneously running water at multiple different sources can lead to a temporary decrease in water pressure. When you notice a low-pressure faucet or shower, check to see how many other appliances or fixtures are running water. This could include other showers, faucets, sinks, toilets, dishwashers, sprinklers, and washing machines. Ensuring that you limit simultaneous running water can help keep your water pressure high.

Water Pressure Issue 5: Clogged Pipes or Valves

Before exiting your faucet or shower, your water runs through a network of pipes and valves. Clogs along this route can disrupt your water flow, causing backups in water distribution. Not only does this lower the water pressure you receive, but it also puts your pipes at risk.

Clogs can be caused by a buildup of minerals, rust, debris, or other obstructions. A plumbing expert will find your clog and fix it at its source to restore your water pressure. This repair often requires a pipe/valve clearing or replacement.
