I just wanted to wrap this up with the solution we came up with for the problem. First of all since 2 of the main pumps are connected to the same system we decided that while testing one, we would shut the other down. The one we test at the time should be enough if we have a fire during that...
As I figured, no one in maintenance knows anything about the design pressure. By "cut out" pressure I assume you mean when the jockypump kicks off. That is usuall 120 or 125psi. I opend a hydrant during the last test and the ground actually rumbled and vibrated, but none of the lines broke...
I will look into finding the answers to these questions. However, usually when I ask questions the response I usually get is "I don't know."
In regard to what is failing in the pipes... I can say it is a little bit of everything. Recently we have replaced 2 or 3 curb valves (one belonging...
Did a little investigative digging and have found that many times the fire pumps are coming on due to jockey pump failure. Frequent changes from 74 PSI to 120 PSI or 80 PSI to 140 PSI could cause some of the pipe line problems, could it not? That in itself seems like an incredible strain on...
Well, my position isn't that complicated. I'm only responsible for testing the system and then reporting my findings to the client. Once my findings are reported and filed in writing my responsiblity ends as I've done my part. It is the client's responsiblity to make the corrections so that...
We're talking about a lot of line and a lot of buidlings. I believe they only put in the pumps because of regulations after the lines had already been placed. They are in the process of closing a lot of the buidlings and i can't see them spending the money to replace the lines. Also, as a...
So what you're saying is that I'm not personally doing anything wrong to cause the breaks? Basically what I do is open a test valve which drops the pressure enough to start the pump and then let it run anywhere from 7 minutes to 30 minutes depending on which pump it is. Then I take reading off...
I currently fill the role of site supervisor of plant protection for large site in Indiana. One of my responsibilites is testing the fire suppression systems on site. There are 2 electric fire pumps on site and a large diesel pump with a 200,000 gallon tank. When testing these pumps I run...
