    Saw a sprinkler fitting I have neve

    Years ago, when I just started in the sprinkler business, I got a call from someone who was opening a branch in Boise. He offered to buy lunch. I got to lunch and there was 2 guys who knew the sprinkler business. I had seen a device similar to what has been discussed. They told me I should...

    Sprinkler Test Gauge Requirements

    I thought using a certified gauge would be a good idea. So I bought some certified gauges. I removed a plug, and installed a certified gauge, and tested the pressure. Every certified gauge gave a different pressure reading with the used gauge. I pulled a certified gauge, installed a...

    Street Elbows

    I think someplace I saw the Street ell was because the old wooden pipe was penetrated by a street ell. If it was not here, it may have been on the sprinkler forum.

    NFPA #25 and providing hydraulic placards... talking about old systems here...

    The decal is there, but the ink has faded and is illegible. We make note on the service report and send a copy to the local FD. And that is where enforcement stops.

    Covering paint spray booth sprinkler heads, tested?

    You can change to a dry chemical system and get rid of fire sprinklers. Every booth I have seen with a dry chem system has paint build up on the walls, floor and duct work. And the fusible links have a build-up of paint. We change the links at each service. We also make sure the nozzle...

    outdoor portable fire extinguishers installation

    In a hot climate, if the cabinet faces South, the temps can reach 150°F. That temp can solidify the ABC powder. Drilling holes in the cabinet can reduce the temp. One of my competitors has changed from glass to plastic break-fronts. They paid an injury claim of $25,000.00 when a client...

    Hanging from drywall ceiling, brand new method

    I have seen an upper pipe used as a support for a lower pipe. But I do not know if that is OK. Would you need to do load calculations to make sure the upper pipe and its supports would handle the weight? If the pipe is CPVC, are those hangers listed for plastic pipe? The nuts holding the...
