Customer called us out for a blockage in the kitchen sink and the garage utility sink. The kitchen sink was backing up into the utility sink. I recommended jetting. Customer also had an accordion trap in the kitchen. I also recommended endure for drain maintenance. I removed the trap from the kitchen, cut off the trap arm holder and installed the new trap. I then went to jet the line and was unable to have a supply of water due to broken angle stop and frozen hose bib. I came back later after while the angle stop was being fixed and assisted the plumber until it was fixed. I then Ran the jetter down the line successfully clearing the blockage.I put everything back together and throughly tested for clogs or leaks.
