Causes And Solutions For Common Water Pressure Problems
Noticing changes in your home’s water pressure isn’t just frustrating — it’s often a sign that something deeper is going on in your plumbing system. Whether your shower feels weaker than usual or your pipes are starting to make noise, inconsistent water pressure points to various issues. If ignored, it can lead to wasted water, higher utility bills or even pipe damage.
At Garvin’s Plumbing and Sewer, we help homeowners get to the bottom of pressure problems quickly so you can protect your property. Here are five common water pressure problems every homeowner should be aware of — plus how we can help you fix them.
1. Your Water Pressure Regulator Is Failing or Missing
The water pressure regulator, also known as a PRV (pressure-reducing valve), helps control the force of water entering your home. Without it — or with one that’s worn out — you might experience fluctuating pressure or water that’s consistently too strong. That added stress can wear out pipes, appliances and fixtures faster than you might think.
Solution: Install Or Replace The PRV
If your home doesn’t already have a house water pressure regulator, it may be time to consider investing in one. If your device is older, we’ll test and replace it as needed. A properly functioning PRV helps keep pressure in the safe range, protecting your entire plumbing system.
2. Pipe Leaks Are Causing Low Water Pressure In The House
One of the most common causes of low water pressure in the house is a hidden leak somewhere in the plumbing. Even small leaks can cause a significant pressure drop. Aside from pressure issues, pipe leaks also waste water and can lead to mold and structural damage.
Solution: Find And Fix The Leak Fast
If you’re wondering how to increase water pressure, the first step, in this case, would be to find and fix the leak. Our team uses reliable leak detection technology to locate even the most elusive breaks in your pipes. Once repaired, we’ll make sure your system is properly pressurized again.
3. Mineral Buildup Or Corroded Pipes Lead To Pressure Loss
Over time, minerals from hard water can build up in your pipes, especially in older homes. This buildup narrows the flow path, causing pressure loss at sinks, tubs and other fixtures. Corroded galvanized steel pipes — common in homes built before the 1970s — can also restrict flow and weaken overall system performance.
Solution: Evaluate And Upgrade Affected Plumbing
If buildup is the problem, we may recommend replacing older piping or sections that have deteriorated. A full or partial repipe improves both water pressure and water quality. In homes with ongoing pressure issues, we’ll also check for a malfunctioning water pressure tank or regulator.
4. Clogged Fixtures And Valves Cause Water Pressure Drops
Sometimes, the issue isn’t with your pipes — it’s right at the fixture. Faucet aerators, showerheads and even shut-off valves can get clogged with sediment or debris, especially if you’ve had recent plumbing work or live in an area with hard water. These issues can lead to low water pressure at specific spots in the home.
Solution: Clean Or Replace Clogged Components
Our plumbers will inspect your affected fixtures and valves to determine if cleaning or replacement is needed. If the problem is widespread, we’ll evaluate the condition of your whole system and advise on how to increase water pressure safely with the help of proper regulation and maintenance.
5. Pressure Spikes From The City Supply Can Affect Your Home
Water from the municipal supply can come in at pressures well above what your home’s plumbing is built to handle. Without a water pressure relief valve or PRV in place, these spikes can stress pipe joints, damage water heaters and shorten the life of dishwashers and washing machines.
Solution: Install A Pressure Relief Valve Or Adjust Your Existing PRV
A professional can measure the incoming water pressure and install or adjust your water pressure relief valve accordingly. This small device makes a big difference in protecting your pipes and fixtures from excess pressure.
