Facing the Endless Cycle of Pipe Failure?

If you manage a commercial or multi-family property, you know that internal pipe corrosion is a silent disaster. It starts unseen, but it always leads to expensive, disruptive problems.

  • Endless Pinhole Leaks: Constantly budgeting for repairs that just address the surface problem can be tiring, especially when leaks simply reappear.

  • Expensive Water Damage: Just one leak can result in thousands of dollars in damages, including structural repairs, toxic mold removal, and the need to replace drywall and flooring.

  • Tenant and Guest Disruption: Few things can ruin a property’s reputation like water shutdowns and the hassle of displacing frustrated tenants, residents, or hotel guests.

Simply fixing the symptom isn't the answer - you need to fix the system.

Our Proven Solution: Phosphate Water Treatment

Instead of costly repiping or endless repairs, we restore your plumbing from the inside out. Our industry-leading phosphate technology has been a trusted method for over 75 years to stop corrosion before it starts.

How It Works

Our approach is straightforward, safe, and highly effective.

  1. Protective Coating: We introduce a food-grade, NSF-approved phosphate blend into your building's water supply.

  2. Internal Pipe Restoration: This compound forms a protective, ultra-thin coating on the inner walls of your pipes, shielding them from the corrosive effects of water.

  3. Ongoing Protection: As long as our expert technicians maintain your system, this protective barrier stays in place, managing corrosion and preventing pinhole leaks across your entire plumbing network.

This solution has proven its effectiveness in all kinds of plumbing systems, including galvanized, copper, iron, and stainless steel.

What Our Customers Say

  • Hotel

    “As the Area Director of Engineering Operations-America West for Hilton Worldwide, I used and recommended the water treatment program provided by W.C Service at many of my 100+ hotels. The water treatment system was able to save our hotels money in water costs, shutdowns, and labor costs by stopping the corrosion and pinhole leaks in the domestic hot water plumbing systems.”

    - Jim Hart, Retired Area Engineering Director

  • Condo

    “In my capacity as a Property Manager for over 1000 condominium units in a portfolio of fifteen properties, I cannot stress enough the importance of implementing a water treatment system for control of copper pipe pinhole leaks. W.C. Services has installed water treatment systems in many of the properties that we work with; all with very good results. The pinhole leaks practically disappeared resulting in reduced costs for plumbing and consequential damages expenses, as well as improvement to quality of life to residents to not have to deal with unexpected problems. W.C. Services is very easy to work with and super responsive. I would heartily encourage anyone to seriously consider this system for their property.”

    - Pya Darzentas, Property Manager

  • Homeowner Association

    “I have been the General Manager of Le Parc Homeowners Association in Century City consisting of 176 luxury condominium units contained in 15 Chateaux for over 30 years. Many years ago, the property was plagued with almost daily pinhole leaks in the horizontal copper tubing hanging from the ceilings of the subterrain garages. Pinhole leaks were starting to occur in the vertical lines which was a big concern that prompted our search for a solution. We happened to find W.C. Service. They installed their water treatment system immediately, and I mean immediately, the pinhole leaks were reduced to just a couple months the first year, maybe 1 or 2 in the next few years and then none for many,many years. It’s really a ‘no brainer’ type of decision contracting with W.C. Service. The value ($$$$$) they provide is truly remarkable. I am a big fan and believer in W.C. Service and what they accomplish here.”

    - John Burton, General Manager

  • Condo

    "As the General Manager of a prominent condominium complex in Newport Beach, CA, I've seen firsthand the challenges that come with constant plumbing issues—especially pinhole leaks in our hot water lines. These leaks were not only expensive to repair but also required remodeling from the water damage. Over a year ago, we decided to partner with W.C. Service Company to install their water treatment equipment on our hot water system. Since then, we haven’t had a single leak. Their solution has truly made a difference, and I wholeheartedly recommend their water treatment services to anyone dealing with similar issues."

    -Fatima Lahouty, General Manager
