Customer said that she kept getting a bad smell from the sinks and toilet, my partner and I did a diagnostic of the drain line and came up with installing stutter vents in the line so air can be pulled into the line to slow better flow in the drainage, my partner recommended three vents but customer decided to go with only two vents. We also fixed the loose handles on one of the bathroom facet sets to insure proper water flow aswell as a even clean look.
