Does my home need a pressure regulator?

What a water pressure regulator does for your home A water pressure regular reduces the pressure of the water coming into your pipes. It takes high-pressure municipal water, which can come in at up to 150 psi (pounds per square inch), and reduces it to 50 to 80 psi—a much safer pressure for your home's plumbing.

Should I install a pressure regulator?

While most domestic pipes can comfortably support a water pressure of up to 80 PSI, if the pressure goes beyond this, you could be in for some serious plumbing issues. If you need further convincing, you should be aware that installing a pressure regulation valve will protect your system from suffering excessive wear and tear.

Why does my water heater leak?

Water heater leaks and bursts are a very common occurance. Typically this is caused by higher than necessary water pressure. Water expands as it heats up. Most water heaters have what is called an “expansion tank” that is meant to offload this expansion of water. In homes with high pressure your hot water tank may have too much water because the pressure is forcing more water than necessary into it. When the water expands from getting hot it has nowhere to go. Resulting in leaks and tank bursts.
