Nothing is more frustrating than stepping into the shower only to be met with a weak trickle—or worse, experiencing pipes that rattle from high water pressure. Whether you’re dealing with low pressure in the bathroom or inconsistent flow throughout your home, water pressure issues are a common concern for homeowners in Wisconsin.
At Brisc Plumbing, we’ve helped homeowners in Watertown, Beaver Dam, and Oconomowoc identify and fix pressure problems quickly and affordably. In this post, we’ll break down the most common causes and what you can do about them.
Residential water pressure is typically measured in pounds per square inch (PSI). The ideal range is between 40–60 PSI. Anything significantly lower or higher can cause problems with your plumbing system and affect your water appliances.
Over time, mineral buildup, sediment, or corrosion can reduce the internal diameter of pipes or clog faucet aerators and showerheads.
What you might notice:
Weak flow in specific fixtures
Uneven pressure in certain rooms
Solution:
Try cleaning aerators or replacing affected fixtures. If the issue persists, your pipes may need descaling or partial replacement.
If you live in an older home, galvanized steel or iron pipes may be deteriorating internally, restricting water flow.
What you might notice:
Gradual loss of pressure throughout the entire house
Rusty or discolored water
Solution:
Call a professional plumber to assess and potentially replace outdated plumbing.
Most homes have a pressure-reducing valve (PRV) near the main shut-off. If this device fails, you may experience low or fluctuating pressure.
What you might notice:
Water pressure that changes suddenly
Whistling or banging sounds in pipes
Solution:
A faulty pressure regulator often needs to be adjusted or replaced by a licensed plumber.
Leaks reduce the volume of water available in your pipes, which can cause drops in pressure.
What you might notice:
Unexplained water pooling
A spike in your water bill
Audible hissing near fixtures or pipes
Solution:
Even small leaks can waste hundreds of gallons. Let a pro locate and repair leaks before they cause bigger problems.
Sometimes, the problem lies outside your property. City water main repairs, high demand, or changes in municipal water pressure can affect your home.
What you might notice:
Low pressure in the entire neighborhood
Sudden changes after city work in your area
Solution:
Contact your local water utility to report the issue or confirm if maintenance is underway.
While low pressure is a nuisance, high pressure can be even more damaging—putting stress on appliances, valves, and pipes.
Signs of high pressure:
Banging or knocking pipes
Leaking fixtures
Water heater issues
If you suspect pressure that’s too high, it’s important to have your system tested and regulated. A pressure-reducing valve may need adjustment or replacement.
