What Are Valves and Regulators?
Pressure-reducing valves and regulators serve as essential control points for the water flowing through the pipes in your home or ADU. By managing downstream and upstream pressure, these systems help prevent backflow and ensure water can be safely poured from faucets. These are the unsung heros of your plumbing system, keeping everything flowing correctly and allowing you to shut off water in the event of an emergency.
The Importance of Pressure Control For Homes and Businesses
At Waterfront Plumbing, we provide full diagnostic inspections that evaluate both upstream and downstream sides, regulate pressure, and identify issues with force balance, diaphragm tension, and spring-loaded valves. The result: maintaining the ideal flow rate in your home and business is made easier than ever.
- Functional pressure reducing regulators protect fixtures, furniture, and appliances from high-pressure damage.
- Improves water conservation and reduces waste for homes and businesses.
- Reduces unpleasant noise and vibration caused by inconsistent flow
- Provides force balance that extends the life of valves and piping
- Prevents costly repairs by reducing wear on diaphragm tension and spring-loaded systems
- Keeps your plumbing code-compliant and efficient

I can't thank them enough for all the work they did. They helped replace old pipes in the main home and set up new plumbing for our ADU. I called other companies and they were the most affordable, but also got the job done in a timely manner. I haven't had any issues and it passed inspection. Thank you for all your work, will definitely use again. Asako C2024-11-30Trustindex verifies that the original source of the review is Google. We had a hot water pipe leak under our slab and fished around for quotes from a few companies after our initial quote came out to ~$6K. Marco was a referral from a friend and he came out the same day I called him, and came back the next day and completed the work in a few hours! He’s a really nice guy and very knowledgeable. He is also reasonably priced. Could not recommend them more! Mike2024-06-16Trustindex verifies that the original source of the review is Google. I asked Marco at waterfront plumbing to come in and snake my drains since I had an emergency with my sewer backup from the toilet. He had his guys come in the next 2 hours of the call, and cleared up my lines. Very happy with the service and comfortable with the pricing.
