Reason for flashlight in daytime.
A contractor was to add a section of pipe onto an existing line of pipe. At the same slope of existing pipe. At the end water spills out of.
The last few feet of existing pipe had the top exposed. A 4' level showed those few feet were falling backwards. That meant the existing pipe had to be corrected before new pipe added. But how much is backwards?
I pulled out my Coast HP1 and slid it to spot mode. Now a flashlight competing with sunshine is like Mike Tyson vs Pee Wee Herman... sunshine wins.
The pipe had a stain inside where water flowing leaves a trail. With reverse grade the stain gets wider upstream inside of the pipe until proper grade occurs.
In this case I stuck a rain coat over the end, shined the HP1 upstream and saw only 1 section was backwards.
The irony is this crew scoffed at me a few days ago when I showed them the not 1 but 2 flashlights in my pockets in daytime.
