    3 way shutoff valve

    I called a plumbing company to replace a leaking pressure reducing valve (black left) but the shutoff valve (silver right) got triggered after water was restored. It was stuck to providing water only to fire sprinkler but nothing inside the house. The person left without fixing it, since he said it is part of a fire sprinkler system that he is not licensed for . I called John the next day and he came the same day. He tried to reset the shutoff valve and tried to push down the stuck part but to no avail. He ordered the part and got it replaced. He is honest, professional, knowledgable and really care for his customer.

    Fire sprinkler head that was dripping, alerting us of a bigger problem than we thought.

    So thankful to God for guiding my husband to find John Harden and his company. John seems to be a very honest and professional individual. Even by phone he is courteous, making himself available when one calls. He is patient in listening and understanding inquiries, then is thorough in explaining. He gave an estimate over the phone and explained possible scenarios. John offered to come to my home earlier than originally scheduled. This was after working on another long overnight job with his crew. I appreciated him still showing up on time. He inspected the fire sprinkler head that had been leaking the week prior. I appreciated the knowledge and honesty he shared. He didn't want to over charge. He mentioned that he could return and thoroughly inspect the area once the ceiling was cut open. Honest hard working individuals need to be applauded and recognized for their honor and integrity. My plumber came out & cut open the ceiling. John Harden was nice enough to take the call and communicate with my plumber and come to a conclusion. John Harden came back and inspected thoroughly. Helped me find out that our RainDial controller wasn't working properly. He also showed me the pressure build up on the fire sprinkler gauge before turning on and off the water sprinklers for the yard. He explained the process of static build up. John basically schooled me on valuable information a homeowner should already know if they have a fire sprinkler system installed in their home. John ended up installing a new fire sprinkler pressure gage and a pressure release device at the back of the house. He had a lot of patience with me following him around and asking questions. With his permission, I recorded his instructions. It was for my reference and also to share with my family because of my forgetfulness. Thankful for the reasonable price charged, not to mention with superb service. I have to say that God sure used John Harden in our time of need. In a sense he rescued us by helping prevent what could have been a devastating nightmare. Again, thankful for his time and honesty. All in all, my husband and I are so thankful for John's service and professionalism. Impressive boss with integrity that can be trusted. Harden Fire Protection will be on my permanent list to call and refer others to when Fire Safety arises.

    Highly highly recommend John-harden fire protection! Called John back in September 2021 because of fire damage on a rental that needed the fire sprinkler replacement. He came on time, had super easy communication, was super nice and helpful. Went through city permit, new drawing for the pips lines, final city inspection. He did all this in no time!

    Location of sprinkler pipe was in a closet.

    I had a great experience with American Fire Protection Systems, Inc. from start to finish. I…read moreinitially spoke with Danny over the phone regarding residential fire sprinkler work at my home, and he was incredibly informative, kind, and professional. He took the time to provide thoughtful feedback and guidance, and even offered to FaceTime with me so I could walk him through the scope of work. That alone gave me a lot of confidence. Danny put my mind at ease knowing the work--simply capping off a fire sprinkler--would be handled correctly, safely, and fully up to code by a licensed professional. Scheduling was seamless, and they were able to send a technician out first thing the very next morning at 7:00 AM. Erik, the service technician, arrived right on time and was equally professional and knowledgeable. He assessed the situation, confirmed what needed to be done, clearly explained the process and timeline, and got right to work. His work was quick, efficient, and clean, and he was someone I felt completely comfortable having in my home. I would absolutely use American Fire Protection Systems again for any future fire sprinkler needs and highly recommend them to anyone looking for a company that values professionalism, competency, efficiency, and outstanding customer service.

    I highly recommend American Fire Protection Systems. When I had a pipe leak that turned out to be…read morethe sprinkler system pipe, they were the only ones who knew how to shut the water off. Golden State Water didn't call back until hours and hours after I reported a water leak emergency, and the regular plumber who came out (while a really excellent person) unfortunately didn't have the licensing or training on how to solve this. The team at AFPS hopped on a FaceTime call with me and talked me through locating and shutting off the water and open the drain valve to prevent further water damage. Afterwards, they were able to come out and fix the specialized pipe. Their price was reasonable, they had a positive attitude throughout, and even identified a problem with the build where it looks like the builder didn't put a nail plate in the stud to protect the pipe. They installed a nail plate at no added cost at their own expense. Overall, they solved what was a quickly growing disaster and I am very grateful for their support. Also, although I'm leaving a glowing review--they never asked for a review. They didn't offer freebies of any kind for a review like I've seen with some other businesses. These guys are the real deal and they'd be the first ones I'd call if I ever had a similar issue in the future. Thanks for your help, AFPS!
