Western States fire protection performs quarterly an annual testing of our Fire equipment for all required PNM sites. They also do our annual backflow prevention for us. I personally have been doing business with Western states Fire Protection company for the last 10 years. It has been a great privilege and pleasure working with the Albuquerque branch of Western States fire protection. They have always been on the job when they promise and have done an excellent job for PNM. As a person responsible for approximately 30 buildings, I would personally and professionally recommend this company with highest regards.
