High water pressure is one of the main reasons water heaters leak prematurely. Plumbing codes require that your home's water pressure be 80 pounds per square inch (psi) or less. Most experts recommend 50-60 psi.
The ideal water pressure level is between 50-70 PSI.
If your water pressure goes above 70 PSI (even occasionally), you should install a pressure regulator to your main water line.
The ideal range of normal water pressure for a house is between 30 psi (pounds per square inch) and 80 psi. Anything over 80 psi is considered too high and could damage your plumbing system.
My research seems to indicate that ALL tankless heaters regardless of type actually require 30-50 psi dynamic in order to function properly.
Expansion tanks are pre-charged with a 40 PSI air charge. If the inlet water pressure is higher than 40 PSI,the expansion tank's air pressure must be adjusted to match that pressure but must not be higher than 80 PSI. *Highest recorded inlet water pressure in a 24-hour period of regulated water pressure.
Most well tanks come set at 30/50. The cut-on pressure for the well pump is 30 psi, so the pressure of the tank should have a pressure of 28 psi. If your well tank is on a 40/60 pressure switch, your pressure setting should be 38 psi.
If the pressure inside the expansion tank is too high, it can be corrected by opening the Schrader valve at the top of the tank.

Normal water pressure range
In general, residential water pressure ranges between 45-80 psi (pounds per square inch). If your water pressure is under 40 psi, it's considered low.
Water heaters are manufactured to withstand pressure up to 150 pounds per square inch (psi), but anything above 80 psi is very bad for them and plumbing in general.
But your pressure should always be somewhere between 1 and 2 bar.
Most residential plumbing systems are designed to handle 40 to 60 PSI of pressure, with 80 PSI being the typical maximum and anything over 100 PSI being possibly detrimental to plumbing components.
The higher the psi, the more force the water is putting on your pipes. The ideal water pressure range for most homes is between 60 and 70 psi. If your water pressure is 80 psi or higher, you're likely going to run into some serious plumbing problems.
The water pressure in your house measures how fast water travels through your pipes and out of your faucets. Normally, the standing residential house has a water pressure of around 80 PSI (pounds per square inch). Anything above 80 PSI is considered too high and can cause serious damage to your pipes and equipment.
Indoor water pressure typically falls between 45 and 65 psi, considered safe and efficient for any household plumbing system. Maintaining water pressure within this recommended range helps safeguard against potential damage to pipes, fixtures, and appliances.
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.
Pressures above 80 psi are too high. Whereas low water pressure is more of a nuisance than a serious problem (some fixtures, like washing machines, have minimum pressure requirements), high water pressure carries with it a significantly increased risk of damage to pipes, joints, fixtures and seals.
While 50 to 70 pounds per square inch (psi) is the ideal range, most plumbing fixtures are designed to work with water pressure up to 75 psi. Anything higher than this can damage your pipes and fixtures.
With high water pressure flowing and stopping in your pipes, it can cause long-term damage like small leaks. Might not sound too bad, but these leaks can lead to structural damage and even pipe bursts. It can damage your hot water heater.
Pressure is normally higher later at night when there is less of a water demand, and lower in the morning when more water is being shared by many. No matter what the cause, fluctuating water pressure and flow can disrupt the way your home works.
The maximum temperature is 210℉ (99℃) and maximum pressure is 160 psig (1100 kPa) for these potable hot water tanks.
You can tell if your thermal expansion tank is working by pushing the air valve (Schrader valve) on the bottom of the take and seeing whether or not air comes out. If air comes out, your expansion tank is working. If nothing or water comes out your tank is bad and needs to be replaced.
If the cut-in pressure was 30psi, the air pressure should be 27psi; 40psi – 36psi and so on. When the air pressure is correct (Fig 1) the pressure tank still contains a small amount of water when the pump starts at 20psi, ensuring a smooth flow of water.
Overinflating tires makes them more stiff and inflexible. When you encounter anything on the road, like potholes, curbs, or debris, you have a higher chance of getting tire damage because of it. They'll also make your vehicle's ride much more uncomfortable – you're sure to feel every bump in the road.
