High Water Pressure Repair
Protect Pipes and Appliances
Banging pipes, toilets that keep refilling or supply hoses that burst without warning? Our plumbers bring excessive water pressure down to a safe level and stop the damage it causes.
High Water Pressure Repair Before Leaks and Failures Add Up
Strong water pressure might feel good in the shower, but excessive pressure quietly wears out your plumbing. Every valve, fill valve, faucet cartridge, supply hose and appliance solenoid is designed for a limited pressure range. When pressure runs well above it, seals wear faster, toilets run or hiss, faucets drip and washing machine hoses can burst. Water heaters may discharge from their relief valves. Pipes bang when valves close quickly, and sprinklers spray mist instead of droplets.
High pressure usually has one of three causes. The home may have no pressure reducing valve despite high city pressure, the existing regulator may have failed, or thermal expansion from the water heater may be spiking pressure in a closed system. On wells, a pressure switch set too high can also be responsible. Our high water pressure repair service measures pressure accurately, identifies which cause applies and corrects it, protecting your plumbing and appliances from further damage.
High Water Pressure Repairs We Provide
We correct excessive water pressure in homes and commercial buildings, installing and adjusting regulators, adding expansion tanks, quieting water hammer and repairing the leaks and worn components that high pressure has already caused.
Regulator Installation
Add pressure reducing valves to homes receiving excessive city pressure.
Regulator Repair
Adjust, rebuild or replace failed regulators letting pressure climb too high.
Expansion Tanks
Install or recharge tanks that absorb thermal expansion from water heaters.
Hammer Arrestors
Install water hammer arrestors that stop banging when valves close.
Supply Lines
Replace worn rubber hoses with durable braided stainless steel supply lines.
Damage Repair
Fix dripping faucets, running toilets and leaks caused by high pressure.
Thermal Expansion: The Hidden Cause of Daily Pressure Spikes
When water heats, it expands. In an open system, that extra volume simply pushes back into the city main. But most pressure reducing valves, along with some meters and backflow devices, act like one-way gates, creating a closed system. With nowhere to go, the expanding water drives pressure up sharply every time the water heater runs. A home set to 60 psi might spike well beyond 100 psi until someone opens a faucet and relieves it.
These spikes often go unnoticed, but they show up as dripping water heater relief valves, toilets that suddenly refill and leaks that appear without explanation. The solution is a thermal expansion tank, a small tank with an air cushion that absorbs the extra volume. Codes commonly require one in closed systems. The tank must be sized for your water heater and precharged to match your house pressure, or it won’t work properly.
Why Homeowners Choose Our Pressure Repairs
We don’t just turn a regulator screw and leave. Our licensed and insured plumbers measure static pressure and record peaks over time to catch thermal expansion spikes that a single reading would miss. We install quality regulators, size and precharge expansion tanks correctly and add hammer arrestors where needed. We also check the damage high pressure may already have caused, from worn fill valves to aging supply hoses, and repair it properly.

Benefits of Correcting High Water Pressure
Correcting high pressure extends the life of faucets, toilets, valves, water heaters, dishwashers and washing machines. It reduces the risk of burst supply hoses and sudden leaks that cause major water damage. Pipes stop banging, toilets stop refilling on their own and faucets stop dripping. Water heater relief valves stop discharging. And moderate pressure reduces wasted water from leaks and excessive flow, which can lower your water bills over time.
High Water Pressure Repair in CA, TX, FL
We provide high water pressure repair for residential and commercial clients in CA, TX and FL, including hillside neighborhoods and low-lying areas where city supply pressure often runs well above recommended levels.
Stopping Water Hammer and Noisy Pipes
That loud bang when a washing machine or dishwasher valve snaps shut is called water hammer. High pressure makes it worse, and the shock can damage plumbing.
Water moving through pipes has momentum. When a fast-closing valve stops it abruptly, a pressure wave travels back through the piping, causing banging, vibration and stress on joints, valves and appliance components. Loose pipe straps and unsupported runs make the noise even louder and the vibration worse.
Lowering excessive pressure reduces the force of these shocks. Water hammer arrestors, small devices with sealed air cushions, absorb the wave near the appliance or fixture. Securing loose pipes adds further improvement. Together, these steps quiet your plumbing and protect it from repeated stress over time.
How Our High Water Pressure Repair Works
We discuss your symptoms, check the water heater relief valve and look for an existing regulator and expansion tank near the heater.
Static pressure is measured, and when needed, a recording gauge captures peak pressure over a full day to detect thermal expansion spikes. We explain whether the cause is missing or failed regulation, thermal expansion or both, along with your repair options, what each one involves and the pricing for each.
Approved repairs are completed, such as installing or replacing a regulator, adding a correctly sized and precharged expansion tank or installing hammer arrestors. Pressure is then set to a healthy level and verified. We also replace worn fill valves or supply lines that high pressure has already damaged.

High Water Pressure Repair Questions Answered
What are signs of high water pressure?
Banging pipes, running toilets, dripping faucets, burst hoses, a dripping water heater relief valve and very forceful fixtures are common signs.
What pressure is too high?
Codes commonly require a pressure reducing valve above 80 psi. Many plumbers recommend keeping household pressure between about 40 and 60 psi.
Do I need an expansion tank?
If your home has a regulator or check valve creating a closed system, an expansion tank is usually required to control thermal expansion.
Can I adjust my regulator myself?
Small adjustments are possible, but without a gauge you can’t verify results. Failed regulators won’t hold settings and need replacement.
Will lowering pressure reduce shower performance?
Not noticeably within a healthy range. Most fixtures are designed for moderate pressure and still deliver strong, comfortable flow at that setting.
