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...

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...

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.

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...

ABC powder makes a mess, the advantage to ABC powder is the low cost. The powder melts at 150°F, coating the burning material and excluding oxygen. Clean up is a problem. Clean agents, Halon, Halotron and water mist do not make a mess, but are more costly than ABC powder. There are...

I have done IT&M for 30 years, portable fire extinguishers, special hazard installs and sprinkler repairs. I love my job, and customers. I have the freedom to fire customers if I need to, but have not had to fire very many. You will need a wife who understands the gap in working and getting...
