I recently built a brutus system and I'm having trouble with my burners. I have 3 HP jet burners and they are all attached with 1/2 black pipe. Each burner has a shut off valve and the pipe all leads back to a 30PSI regulator. When I light the system, the first one lights but there is barely a flame and the 2nd two wont light at all. Its almost like its not getting any gas. This is my first time using a system that only uses one propane tank. Did I need to buy a 30PSI regulator for each burner, then connect them all together?
