I understand setting the relief pressure at the highest pressure line but if you fit that line down won’t the lower psi lines spike up the pressure that your highest line is set at?
You are on to something… and why gating lines down can be extremely problematic. This is why Rick Brewer advocates for utilizing multiple engines and setting up pressure zones for each apparatus to function in.
Good question. Personally, I prefer to set the relief valve with a dedicated discharge. A side note is to test different relief pressures as you do your morning check out.
Hello I hope you are well I work in an oil company I am a fire truck driver I have a problem with the truck in the control panel when I accelerate the pump with the start button not I think because that discharge relief valve please help me
I had to pull some of these down. I’m in the process of re-doing this entire series though. You might be able to find the original episodes I pulled down still at therollsteady.com in our Pump School with Rick Brewer.
