Our Comprehensive Water Pressure Services
At Knight & Day Plumbing, we offer a full range of professional services to help regulate and optimize your water pressure:
Water Pressure Assessment
We begin with a thorough inspection of your plumbing system using precision tools to measure and monitor your water pressure. Our technicians check for both high and low pressure issues and provide clear recommendations based on your home’s specific needs.
Pressure Regulator Installation
High water pressure puts stress on pipes, fixtures, and appliances. We install pressure-reducing valves (PRVs) that control the flow and protect your plumbing system from long-term damage. Our team ensures the regulator is properly calibrated and meets city code standards.
Leak Detection and Repair
High water pressure often leads to small leaks that can quickly become big problems. We use modern leak detection equipment to locate hidden issues in your pipes, fittings, and joints, then perform precise repairs to prevent water damage and lower your water bills.
Fixture Upgrades
Older faucets, toilets, and showerheads may not be built to withstand elevated water pressure. We can upgrade your fixtures to high-pressure-tolerant models that offer improved performance and longer lifespans.
Maintenance Services
Ongoing maintenance is the key to long-term water pressure stability. Our technicians offer regular system checks, valve adjustments, and preventative care to keep your pressure levels balanced and your plumbing system protected.

Why Choose Cassidy Plumbing For Water Pressure Regulation?
Common Water Pressure Issues
Water pressure issues can vary by home, plumbing system, and usage patterns. Here are some of the most common problems we handle:
Water Hammer: Loud banging noises from your pipes caused by high pressure. We install air chambers or shock absorbers to eliminate the noise and pressure surges.
Leaking Pipes: Constant pressure can cause pipe joints to weaken and burst. We repair or replace affected sections and adjust your system pressure accordingly.
Damaged Fixtures: Faucets and valves that are leaking or breaking down due to excess pressure can be replaced with more durable, high-performance alternatives.
Clogged Pipes: Mineral buildup or debris can restrict water flow, leading to uneven or low pressure. We clear and clean affected areas to restore full functionality.
Faulty Pressure Regulators: If your existing regulator isn’t working or is installed incorrectly, we’ll repair or replace it to ensure steady, code-compliant performance.
When to Call a Professional
Some minor water pressure issues may be resolved with basic troubleshooting, but there are certain signs that it’s time to call a licensed professional:
Consistently High Water Pressure: If your pressure exceeds 80 PSI, a regulator is required to protect your plumbing.
Low Pressure Throughout the Property: If multiple fixtures are affected, it could indicate a larger issue with your main water line.
Frequent Leaks or Fixture Failures: Recurring leaks may signal too much pressure or system imbalance.
Sudden Loss of Pressure: No pressure or very low flow may point to a major issue like a break in the line or a failed valve.
If you notice any of these signs, contact Knight & Day Plumbing immediately. We’re available 24/7 to handle urgent situations throughout Pittsburgh.
Most Common FAQS
If your faucets spray, pipes bang, or fixtures fail frequently, your pressure may be over the recommended 80 PSI. We can test and install a regulator if needed.
Yes, low pressure in one area often indicates a localized issue, such as a clogged aerator or a valve problem. Widespread low pressure usually suggests a bigger system issue.
On average, a pressure regulator can last 10–15 years. Regular maintenance and adjustments can help extend its lifespan.
We recommend professional drain cleaning every 12 to 18 months, especially for households with high usage or older plumbing. Preventive maintenance can extend the life of your pipes and prevent major blockages.
Some regulators have a simple adjustment screw, but it’s best to have a licensed plumber check it to avoid overcorrecting and damaging your system.
