Ideal water pressure for your home

What is plumbing water pressure?

Water pressure is the force at which your water flows out of the faucets. Water pressure is measured in psi (pounds per square inch). Ideally, the range should be 40 to 60 psi. If your water pressure is too low or too high, it can damage your plumbing fixtures and appliances leading to costly repairs.


The average household uses more than 300 gallons of water each day, so issues with your water pressure are a cause for concern.


If you’re experiencing low water pressure, first check with your neighbors. If they are also experiencing low water pressure, the issue is with your water supplier. Contact your utility company to make sure they are aware of the issue and are working to resolve it.

Why do I have low water pressure?

Causes of Low Water Pressure

Low water pressure can be a result of many different problems.  Some of the most common causes are

  • Partially closed water main valve
  • Shut or blocked water meter valve
  • Clogged or blocked pipes
  • Corroded pipes
  • Undetected leaks
  • Crack in main public water supply pipe
  • Faulty plumbing fixture
  • Faulty hot water heater
  • Pressure regulator valve is failing

Let’s take a closer look at possible causes of low water pressure.

Partially Closed Water Valve

If your low water pressure is the result of a partially closed water valve, this is a quick DIY fix. Your water main valve is located near where the main water pipe enters your home through the foundation. Typically, near an outside wall or near your hot water heater. The shut-off valve may also be located outdoors inside a utility box. Simply open the water main valve by turning it all the way to the right.


If you find that your main water supply valve is corroded, broken, or leaking, call the plumbing professionals at Olde Town Plumbing to replace the valve and restore your water pressure.

Shut or Blocked Water Meter Valve

Another possible cause is your water meter valve is shut or blocked. The water meter valve is located next to your water meter on the outside of your house. If you notice an increase in your water bills, call your water company to inspect the meter to ensure that you are getting accurate readings.

Corroded Pipes

If you own an older home, your piping may be corroded and in need of replacement. Galvanized steel was commonly used in older homes. This was the best alternative to lead pipes at the time. However, after years of water exposure, galvanized pipes rust and corrode. Modern piping materials are now made to last for years. Give us a call. We’ll be happy to discuss your whole-house repiping options.

Faulty Water Heater

A faulty water heater can be the cause of both low hot and cold water and may need replacement. The buildup of sediments in the bottom of the tank or kinks in the flexible water pipes used in water heaters may be the culprit. If the shut-off valve on the water heater is only partially opened, this can also affect your water pressure.

Clogged or Blocked Pipes

One of the most common causes of low water pressure is a clogged or blocked pipe. A clogged pipe is caused by a build-up of dirt, sand, oil, grease, food particles, and foreign objects. This build-up blocks the water flow through the pipes and causes your water pressure to go down.


The two most common causes of low water pressure in your kitchen sink are a clogged aerator and a clogged cartridge. These are also easy DIY projects. You can buy replacement aerators and cartridges at your local hardware store. The aerator is the mesh screen at the end of your faucet. The cartridge is underneath the sink handle and controls the flow of water. Simply replacing these parts will restore your sink’s water pressure. If you would prefer that we perform the faucet repair, just give us a call.

Faulty Water Pressure Regulator

A water pressure regulator or water pressure-reducing valve is used to regulate the water pressure from your public water main to your home or business. It helps to provide a lower, more consistent water pressure distribution. And it ensures that the water pressure is at a level safe for your pipes. If your water pressure regulator is faulty, it won’t adjust the pressure accurately. This will cause either a spike in your water pressure or a sudden drop in your water pressure. A water pressure regulator valve keeps your water flowing at an optimal rate to provide for your needs and protect your plumbing system.

Leaking Pipes

If you have a leaking pipe, call Olde Town Plumbing to repair or replace your water line right away. Even a small leak can cause a reduction in your water pressure. And it can damage your foundation and contaminate your drinking water. If you can find the source of the leak, try using a rubber patch as a temporary fix until our plumber arrives. We’ll work quickly and efficiently to detect and repair the source of your leak.


If we detect a crack in the main public water supply pipe, this will require a call to your local municipality.

5 Signs of a Faulty Water Pressure Regulator


  1. Low or fluctuating water pressure
  2. Higher than normal water pressure
  3. No water pressure
  4. Strange noises coming from your plumbing pipes and appliances
  5. A leaky faucet
  6. Toilet running constantly

Should I have a Water Pressure Regulator installed?

Not all homes have a water pressure regulator. Water flowing at a higher rate than necessary can damage your plumbing fixtures and appliances. High water pressure can cause leaking pipes, and dripping faucets, and reduce the life expectancy of plumbing appliances like your hot water heater, dishwasher, and washing machine.

Installing a water pressure regulator in your home or business will ensure your water pressure is operating at safe levels for your plumbing pipes and appliances.

How long does a water pressure-reducing valve last?

Most water pressure-reducing valves will last 10 to 15 years.

How can I check my water pressure?

The best way to test your water pressure is with a water pressure gauge. You can purchase a gauge at your local hardware or home improvement store. Shut off all faucets and plumbing appliances. Then, connect the water pressure gauge to your outside hose faucet. Open the faucet to full pressure and read the gauge to measure your water pressure. If your water pressure is above 80 psi it is too high and violates plumbing codes.


Low and high-water pressure can affect one faucet or the whole house depending on the cause. If your water pressure is too low, it is not only an inconvenience, but your plumbing fixtures and appliances may not work properly. And if it is too high, you risk damage to your plumbing systems.
