How to do hydro jetting and drying with a flangeBUMPER:
You are going to need a drill or screwdriver, a batROLL, for this size of flange small & medium multiNUTS, and a flangeBUMPER. Typically, during hydro jetting like this you are required to rope off a 15ft exclusion zone in all directions. Meaning no one is allowed to work within this 15ft radius for safety. Now we are going to apply our flangeBUMPER and shrink that 15ft exclusion zone to only 3ft!
We are attaching the medium multiNUTS backwards to ensure that nothing touches the flange face. Then we will secure the flangeBUMPER onto the pipe spool with our small multiNUTS facing the correct way, with the smallest part of the multiNUTS facing the bolt hole. Finally, we are going to mask off the top of the flange bumper with a piece of bat tape. Make sure that you do not wrap it all the way around, you want an opening at the bottom so that the water can fall out.
Now the water falls at a safe distance for people to work around! The final step is to dry the pipe with an air compressor to ensure that no water is left behind.
