Water Treatment Case Studies

245 Unit Apartment Complex, Los Angeles, CA

This apartment complex in Los Angeles was having significant problems with corrosion-induced pinhole leaks, experiencing more than 20 leaks per year. The property’s maintenance supervisor estimated that each pipe leak resulted in $1,000 worth of repairs and thousands of dollars in property damage. After a comprehensive plumbing system inspection, ANMAC identified the specific type of corrosion causing the pipe leaks and designed a custom-tailored treatment plan. Since the installation of the ANMAC’s water treatment system, the property has not experienced a single pinhole leak.

Over the last five years, ANMAC has saved this property at least $250,000.


150 Room Hotel, San Jose, CA

This older hotel in San Jose was being purchased by a new property management company. Due to abundant pinhole leaks, valve failures, and poor water quality, the purchasing company had planned to repipe the entire building. ANMAC conducted a thorough inspection and determined that a water treatment program could save the building’s existing plumbing system. To date, ANMAC’s water treatment system has kept the building’s plumbing system free of any significant problems.

ANMAC saved this building more than $1,000,000 in repiping costs.


24 Unit Condominium, Los Angeles, CA

This condominium in Los Angeles had a very worn out plumbing system and was experiencing more than one pinhole leak per week due to extensive copper pipe corrosion. Each leak was costing management thousands of dollars in repairs and damage. After a thorough inspection of the plumbing system, ANMAC designed a cost-efficient treatment program which has reduced pinhole leaks by over 75%.

ANMAC has saved this building more than $25,000 to date.


356 Unit Apartment Complex, San Diego, CA

This apartment complex in San Diego was having extreme problems with its numerous water heaters. The water heaters were experiencing leaks, valve failures, and producing rust-colored hot water due to corrosion. The building’s owner had planned to replace each of the 356 water heaters throughout the property. However, in conjunction with a water treatment program, ANMAC serviced each water heater and installed new anode rods. The combination of ANMAC’s water treatment and new anode rods has significantly mitigated water heater leaks, eliminated rusty hot water completely, and even increased water heater efficiency (leading to lower energy costs).

ANMAC saved this building around $250,000 by avoiding the replacement of the water heaters.


368 Unit Apartment Complex, San Francisco, CA

This apartment complex in San Francisco was experiencing pinhole leaks on hot water recirculation lines. After performing a detailed examination of pipe samples from the property, ANMAC determined that the pinhole leaks were being caused by velocity induced corrosion. The hot water recirculation pumps were oversized and producing water flow at too high of a velocity. This high velocity was eroding the interior metal of the pipe wall, degrading the pipe, and causing leaks. ANMAC devised a cost-effective treatment plan and installed circuit setters downstream of each recirculation pump, effectively slowing the speed of the water and significantly reducing pipe wall erosion and the occurrence of leaks.

ANMAC has saved this building more than $50,000.


210 Unit Apartment Complex, Orange County, CA

This apartment complex in Orange County had installed four new Raypak Hi Delta water boilers. The water in Orange County is often extremely hard, making boilers and water heaters prone to damaging scale buildup. After experiencing severe problems with scale buildup and clogging in the boilers of another property, management of this apartment complex sought to protect the new boilers. ANMAC installed its water treatment system on the cold water inlet lines to the boilers and tailored its treatment plan to focus on the prevention scale buildup.

For the last three years, ANMAC has fully protected the new boilers and kept them operational without issue.
