If you tighten the screw the water pressure will be more and if you loosen the screw the water pressure will be less. Turn the screw clockwise to tighten it and increase the pressure, or turn it counterclockwise to decrease the pressure. Do not be too hasty.
Over time, high water pressure wears on your plumbing system and leads to: Leaking Pipes: High water pressure continuously puts too much force on your pipes. Eventually, your home's pipes will likely wear down until they can no longer hold back the water.
If your pressure is higher or lower, then you'll need to install, repair, or adjust your pressure regulator to comply. Adjusting your regulator is easy, as long as it's working properly. Simply tighten the screw down clockwise to increase pressure and counter-clockwise to decrease pressure.
To reduce high pressure in a home, you'll need a Pressure Reducing Valve ( PRV ). In fact, these are often required by code for pressures beyond 80 psi . These devices do exactly what they say, reducing pressures of up to 400 psi down to a reasonable level of your choosing (most are factory set at 45 psi).
Press the valve stem: Place the end of the pressure gauge or a small object like a screwdriver on the valve stem and press down. This will open the valve and release the air from the tire. Check the pressure: Release air slowly in short bursts to avoid over-deflating the tire.
If you discover your tires are overinflated, don't panic. First and foremost, check for any excessive wear or damage. If you find any, it may be best to replace them to ensure your vehicle's safety. If they still appear to be in good shape, it's quite easy to remove the excess air.
If you tighten the screw the water pressure will be more and if you loosen the screw the water pressure will be less. Turn the screw clockwise to tighten it and increase the pressure, or turn it counterclockwise to decrease the pressure. Do not be too hasty.
If you have high water pressure, try regulating that pressure by closing your stop tap ever so slightly. How to find & operate your stop tap.
A sudden increase can be due to a broken pressure regulator or a change in the municipal water supply. Additionally, temperature changes or a burst pipe could cause sudden spikes. If your water pressure increases unexpectedly, it's essential to investigate as soon as possible.
Although it is possible to increase water pressure for a single shower or tap, boosting the whole house using a pump is more efficient and guards against future issues. Recommended Pumps: Stainless steel centrifugal pumps, like the 3 Bar Sentinel.
While you should always stay within this range, you should also never be below 20 PSI, or over 50 PSI, or you risk serious tire damage (more so than with standard overinflated or underinflated tires to a lesser degree). Your car may have different ideal tire pressures for the front and rear axles.
Once you find the main water supply, turn it completely off. Turn all faucets to the 'on' position. Once the water supply is off (you might want to double-check this), turn all the faucets in your home to the 'on' position. This will allow for any trapped air to flow through the water lines.
Adjust the Pressure
The regulator will have a screw or bolt and a locking nut system. Loosen the locking nut with a wrench and using quarter-turn increments, use a screwdriver to turn the screw counter-clockwise (to the left) to decrease water pressure, and clockwise (to the right) to increase water pressure.
Check with your water supplier
It could be that the mains' water pressure has increased, which is an issue with your water network. Call your water company to see if they have set the pressure higher than normal because of maintenance work. You might also find that neighbouring homes have reported the same issue.
Normal water pressure is generally between 40 and 60 PSI. Most homeowners prefer something right in the middle around 50 PSI.
They will perform a thorough inspection of the meter to identify the source of the problem. Once identified, the plumber can replace the damaged parts or repair any malfunctioning components, such as the water meter valve, which will ultimately restore the water pressure.
Water Valves
Two main shut-off valves control the water flow in your home — one on or in your home and one at the meter. If one of these valves is partially or fully turned off for some reason, it can cause your water pressure to decrease considerably.
Anything over 80 psi is considered too high and could damage your plumbing system. On the other end of the spectrum, anything below 40 psi is considered low pressure, and anything below 30 psi is considered too low.
A water pressure regulator, if you have one, is usually located where the main water line comes into the house and after the main shut off valve. This way if you need to work on or change the water pressure regulator you can simply shut off the water main to do so.
