Title: Didn't belong in a box lot
Post by: coolford on October 27, 2018, 05:40:49 PM
I bought this adjustable 15 inch Starrett plumbers level yesterday and it was in a box lot with other Starrett stuff.  However I don't really understand the inclination feature.  On the scale it runs from 1 to 16.  Is this the fall per foot?  I had never seen such an adjustable level before and obviously no one else at the auction knew what it was because I stole the box lot.

It appears they are graduated in 16ths of an inch per foot.

I guess for plumbers to make sure a drain line goes down, so that it drains properly.

Starrett bills this as an "engineer's" level.  Mine was a thank-you gift from my son for helping him with a garage cleanout.  I've used it several times*, and it's been way handier than taping blocks of wood under a regular level.

Mine says, in way tiny text near the scale, something like "1/16" per foot."

*Setting up the outrigger support for a window air conditioner and then testing the unit for proper tilt; checking a subtle tilt on the rear floor of our RV.  That's so far; I'm sure other occasions will arise.

Plumbers grade drain pipe pretty accurately.

Sprinkler fitters grade dry pipe at 1/4" per 10' fir mains, and 1/2" per 10' for branch lines.

Because too steep and the water outruns the...more solid stuff; too shallow a pitch, and stuff moves too slowly.  Either way, you get to learn all about rooting out drains.

in  plumbing terminology its known as the self scouring  effect ( in other words every time you flush your toilet your pipes are being cleaned ) different types and sizes of DWV piping may require differing pitch /fall angles . most all piping be it refrigerant piping ,water supply ect , require some pitch angle as necessary to self drain when not in use and or to prevent refrigerant /oil trapping ect ,.
