Water Pressure Testing

It is essential to understand your water pressure as it's vital to your plumbing system's wellness and the health of your mind.

High water pressure may generally damage your home plumbing system whenever you turn on a tap. On the other hand, low water pressure may jeopardize your sanity by being inconvenient when you're taking a shower. You're supposed to have a routine water pressure check-up as part of your plumbing maintenance checklist.

The ideal water pressure should be over 15 litres of water per minute. We accept a flow rate of 10 -15 litres per minute. Water pressure below 10 litres per minute is considered poor and easily noticeable, for example, while taking a shower, filling a bath, or washing the pots, as it will take longer to fill.

Getting to know when your water pressure is high is the challenging part as only a certain amount of water gets through an outlet at any time. Therefore, you'll need a water pressure gauge and a plumber to determine if your water pressure is high.

If you're not sure of what to do, don't worry, we PlumbGuardian company are here. We shall help with all your needs concerning water pressure. We cover all plumbing aspects to do with water pressure.

Why Test Your Home's Water Pressure?

High water pressure is a risk to your plumbing system. It can cause blowouts in washing machine hoses or flex lines, flooding the house in the process. You should test water pressure even if you have a pressure regulator or pressure-reducing valve (PRV) because the regulator can malfunction anytime. Measuring water pressure can detect if your pressure regulator is malfunctioning; hence, proper action can be taken before the high pressure damages the plumbing fixtures.

What you Need for a Water Pressure Test

What you Need for a Water Pressure Test

 

Choose the Testing Location

If you source your water from the city/municipal water utility, your testing location should be the outdoor hose bib faucet closest to your main water supply line. You should use a tap close to the well's pressure tank if you get your water from a well.

Check for Running Water

Turn off all plumbing fixtures when measuring the water pressure to get an accurate reading. A gauge test for static water pressure, so if you hear any water movement, your pressure gauge reading will lower the false reading.

Install the Pressure Gauge

If your faucet has a hose, remove it, then fix the pressure gauge onto the faucet. Ensure you have an excellent seal to achieve an accurate reading.

Check the Pressure

Turn the faucet and then read the pressure on the gauge's dial. The ideal home water pressure should be between 40-50 psi. Standard pressure regulators have their adjustment up to 75 psi. Any reading beyond 75 psi signifies a faulty pressure regulator which needs to be replaced. In the absence of a pressure regulator, yet your reading is above 60psi, contact our approved plumbers to come and check and fix your water pressure.

Testing at the Washing Machine

Testing at the Washing Machine

You can also test the water pressure in your washing machine's cold water supply faucet. Turn off the cold water and then detach the hose from the faucet. Mount the pressure gauge onto the faucet, then open the faucet to test the pressure.

How do I test Water Pressure?

How do I test Water Pressure?

When testing water pressure, you'll need a simple, inexpensive pressure gauge, available in hardware or a home improvement store. We highly recommend the one with female hose threads that quickly hook up a rubber gasket to form a tight seal and can measure up to 300 pounds per square inch (psi).

Preparation

Turn off all faucets, dishwashers, showerheads, washing machines, refrigerator ice makers, and sprinklers. Any water movement will result in a lower pressure reading.

Hook Up Pressure Gauge

Hook up the gauge to an outside hose bib or faucet. If your water comes from a municipal utility, select the faucet closest to the water meter, but if your water source is a well, select a hose bib that's near to the well's pressure tank.

Measure Water Pressure

Tighten the gauge, then open the faucet all the way. Take the pressure reading from the indicator. The reading for a standard water pressure should be between 40-50 psi. Consult with our plumbers if your water pressure is below or above these values.

Testing Low Water Pressure

When you want to test for low water pressure, you'll need tools like

  • A measuring jug, 1-litre jug, but if you don't have the 1-litre jug (they often vary in size, which can be 500ml or 800ml), then you can also use some simple maths to calculate the water pressure
  • Timer (a timer )
  • Calculator, usually on the phone. (be careful with the phone around water)

Steps

  • Place the 1-litre measuring jug under the tap or shower.
  • Turn the subject tap or shower on full.
  • Observe how long it takes to fill the jug.
  • If the tap/shower takes more than 6 seconds to fill the jug, you have low water pressure.

Testing High Water Pressure

The tool you'll need to measure high water pressure is a water pressure gauge.

Steps

  • Turn off all taps in and outside the house.
  • Fix the pressure gauge to the outside tap
  • Turn on the tap completely for an accurate reading.
  • Observe and review the readings on your gauge. If the reading is above 60psi or less than 40 psi, contact us immediately. A low-pressure reading might signify a leak in your plumbing system.
How to Fix Low Water Pressure in your Home

How to Fix Low Water Pressure in your Home

Knowing the categories of system you use for your water supply is essential when fixing low water pressure. There are three types of systems, a Gravity Fed system, Combi Boiler, and an Unvented system.

Gravity Fed System 

This water system also called a low-pressure system, is used to store cold water storage tank in the loft or roof space or sizeable hot water cylinders located in the airing cupboard. The system is common in older properties that have not been renovated over a long time.

To help solve the low water pressure with this type of system, you will have to add a water pump or replace your system with a modern economic system. Call PlumbGuardian for a quotation; we will come to conduct a quote and survey of your existing system.

Combi Boiler 

These types of systems allow a combination boiler to take its water source from the mains water found outside of your property and supplying water to your home through a pipe. The combi boiler saves space when used in homes.

To solve the low water pressure issue on a combi boiler:

  1. Add a water pump to the mains water feed.
  2. Don't hesitate if you need help.
  3. Come out, contact us, and we shall be there at your service to ensure your combi boiler system operates well.

Unvented System

A separate hot water cylinder is used in this system to store your home's hot water supplied directly from the mains supply source. The unvented system keeps hot water under high pressure and carries the hot water to a loft conversion.

This system is made up of

  • White metal cylinder that holds the water under pressure. It is insulated; therefore, it doesn't feel warm when touched.
  • A separate boiler system.

Solving a low water pressure issue under this system, you will have to add an extra water pump to push the water circulation around your system. Call us today, and our reliable plumbers will come to carry out a survey and provide a free quotation for your system.

How to Address High or Low Water Pressure

How to Address High or Low Water Pressure

Don't panic if your water pressure is too high or low. We have a range of strategies that can be put in place to address high or low water pressure.

High Water Pressure

If your water pressure is too high, install a water pressure regulator on the water main to ensure a maximum water flow of 60 psi. Even if you have a water pressure regulator already established, it's still essential to test the water pressure because pressure regulators can fail to function correctly without noticeable symptoms.

Low Water Pressure

If your water pressure is too low, you should inspect the pressure regulator if you have one set at 50 psi by default. You can improve the flow by adjusting the screw on top of the regulator to improve the flow. If the pressure regulator is functioning correctly, the municipal water utility may supply low water flow to your home.

The low water pressure problem can be solved by installing a water pressure booster that improves the flow any time you open the faucet.

We, PlumbGuardian, are here to help you with all your water pressure issues. You can rely on our efficient and quality water pressure services to achieve the comfortability and safety you desire. We offer the best services so you can count on us.
