How To Increase Hot Water Pressure
You could be experiencing low hot water pressure for a variety of reasons, from a buildup of sediment and scale inside the water heater to too many bends in the plumbing lines. Luckily some simple fixes will increase the hot water pressure throughout your home.
- Have a plumber clean and flush out hard water scale, mineral deposits and sediment build-ups inside the water heater and plumbing lines.
- Replace old pipework and water heaters over 8 years old with new ones to ensure heat is being transferred efficiently.
- If you have several kinks or bends in the water supply intake and outtake lines before the water reaches your taps and outlets, this could be severely affecting your hot water pressure. You could have your plumber repipe the plumbing lines to the areas of the home that have problems with reduced hot water pressure or, if the entire home is affected, a pressure regulator can be installed to adjust the water pressure.
- Finally, double-check your shutoff valve is completely open, even a partial closure will reduce your hot water pressure.
Check The Water Pressure Gauge Again
Is My Water Pressure Too High
The signs are well known: Banging pipes, running toilets, dripping faucets, and running out of hot water very quickly all indicate that the pressure is too high in your system. Test your system with a water pressure gauge, available at any home store for around $10. Simply attach the gauge to any male threaded faucet such as your laundry tub, hose bib, or water heater drain connection and turn on the water. The ideal pressure for the health of your plumbing system and appliances is between 40 and 60 PSI, and building codes in most areas specify that water pressure is under 80. If yours measures over 80 PSI on the gauge, it is definitely time to lower the pressure.

How To Test Your Water Flow Rate: A 3 Step Guide
Checking your water flow rate doesnt take long at all and can help you determine if you have a problem with your water pressure. Simply follow our 3 step guide below to understand what the water flow rate is for your home.
Step one: Collected equipment
Get a water jug of 1 or 2 litres in size, a stopwatch and a calculator .
Step two: Time the output of water in 6 seconds
Put your water jug under your bathroom tap or shower and turn it on for six seconds. Once your stopwatch shows 6 seconds, turn off your tap or shower
Step three: Calculate your litres per minute
Take the amount of water in the jug in litres and multiply this by 10. This will give you your flow rate in litres per minute .
Some consider a flow rate that is less than 10 litres per minute to have low water pressure. Anywhere between 10 and 15 litres per minute is acceptable but can be improved. A flow above 15 litres per minute is considered good.
Install A Water Pressure Gauge
A water pressure gauge is an instrument that can be connected to a pipe system to determine pressure. These gauges are commonly installed close to the water pressure valve for easier adjustment.
Installing a gauge makes sure the water pressure in your home is always kept at optimal levels. Luckily, these items are inexpensive and are readily available in many hardware stores.

Inspect Pressure Reducing Valves
The pressure reducing valve is responsible for reducing the supply of water to a pressure level that is safe for the premises.
This valve is found where the line enters the building.
In most cases you just have to turn the knob or screw that is located on the top of the valve in a clockwise direction to increase the water pressure.
Be careful not to overdo this as it could cause damage to the plumbing.
If you do not notice any difference in the pressure, you may try to clean the parts or replace the valve entirely.
Check For Toilet Leaks
Toilet leaks are a very common problem, and can be a direct cause of reduced water pressure.
Check your toilet mechanisms to ensure that the flow from the cistern to the bowl is as it should be.
In order to check the toilet for leaks, pour a few drops of food colouring in the cistern.
After an hour, check if the food colouring made its way into the toilet bowl.
Obviously, make sure that you do not flush the toilet during this period.
If there is food colouring in the toilet bowl, then you need to repair the flapper or install a new one.
You may also notice that the toilet is filling up the cistern constantly.
If you can hear this whenever you go to check it, then the problem with your low water pressure is a direct result of the toilet.

Clogged Faucet Aerators And Shower Heads
Faucet aerators are the tiny attachments with fine nozzles at the tip of the faucet spout. Aerators look very much like shower heads. They allow air inside the faucet and hence a soft stream of water.
Due to the size of their nozzles, faucet aerators are easily clogged by debris, pipe corrosions and mineral deposits. To learn how to fixed clogged aerators check out this post, while this other post will show you how to clean a shower head.
How To Improve Water Pressure Using The Pressure
If your citys water pressure is high and your valves are open, the next problem to check is your machinery. Check the water main for a pressure-reducing valve. If one of these valves is present, it could be the reason for low water pressure in your shower head.
Pressure-reducing valves are present in many homes and commercial spaces. However, one improper adjustment could lead to problems like low water pressure. These devices have an easy pressure adjustment screw on the top of the valve. The typical factory preset is 50 psi, which is standard for water pressure. However, the setting of these devices can accidentally be too low.
If you believe it has been longer than a decade or two since the valve has had a replacement or repair, it is worth having a look. This device could be the reason for all your pressure issues.
- Adjust the screw so that the psi is between 45 and 55. Clockwise turns increase the pressure, while counter clockwise turns will diminish it.
- After adjusting the valve, check the water pressure in your shower head.
- If it is still running low pressure, call an expert like All Dry USA to have a look. You can find a replacement valve at most hardware supply stores and have a pro come in to do the installation.

Do The Simultaneous Use Test
Simultaneous water use, as mentioned earlier, can lead to problems in water flow if water pressure is insufficient. A good hands-on test of water pressure is by doing a simultaneous water use test. Turn on multiple faucets in your home and evaluate whether the output is sufficient for your needs.
If water flow sputters or weakens excessively, then water pressure may be insufficient. Of course, make sure that the pressure remains within the safe levels when you adjust.

Problems With Your Hot Water Supply
Does your hot water supply fluctuate even though you have no problems with your water heater? If so, then the problem may be due to high water pressure. This is because the heater is not given enough time to heat the water before it exits. Low water pressure, on the other hand, can cause excessive heating of water.
How To Adjust Water Pressure Regulator
If the water pressure isnt at the desired level, you can adjust the pressure by adjusting the screw. Tightening it will increase the pressure and loosening it will lessen it. Turning the screw clockwise will increase pressure while turning it counterclockwise will decrease pressure.
This article discusses how to adjust the water pressure regulator.

How To Use A Water Pressure Booster Pump

Sometimes, an entire city or town suffers from barely any water pressure. This indicates that the city is delivering the water supply to homes at a pressure of less than 40 psi. If this is the case, increasing water pressure will require installing a water pressure booster pump.
A booster pump takes the water that comes in and uses an electric pump and pressure tank to increase the psi. You can set your pressure to your liking by using the top dial on the device.
Pumps require installation of at least 3/4 inch copper or plastic water main in the house. The system operates by pressurizing the flowing water supply with compressed air and feeding that water into the home. The installation process is straightforward:
- Attach the main water line that goes into the house to the booster pump
- Attach the pump output to the water pressure tank
- Attach the tank output to the house pipes
Booster pumps can be expensive, but they help with water flow in addition to pressure. The device makes it easy for multiple people to use the shower head or other water-based appliances at the same time. This step makes it easy to run a load of laundry even though someone has to take a shower in hot water. It adds convenience and saves time.
