Plumbing Tidbits
Here is a vast and chaotic collection of little tidbits i've written down to remember as I advance my plumbing knowledge. I'm not sure if this applies everywhere but it does in the part of Canada I am in (same as the rest of the plumbing section of this website). Again, do not be afraid to utilize CTRL+F...
at least for storm drainage, support horizontal runs every 4 feet and vertical runs at every storey
keep in mind of flood level rim when roughing in fixtures
don't use primer on test caps
83" clearance for pipes from the floor in a parking garage
a trophy piece is a fitting that has a section of pipe welded into it but cut, a used fitting
if I continuous vent is leaking at the fitting and needs to be cut out, you can back vent it with a 45 if you don't have the proper spacing or fittings to just redo it
vertical ball valves should close by pulling down
minimum piece for 3/4" uponor is 3 inches
min piece for half inch uponor is 2 inches
bubble touching second line on level is quarter inch per foot slope (first line is eighth)
3 types of individual vents: back vent, dial vent and individual vent
minimum piece for one inch uponor is 4.5 inches
cast iron is 10ft lengths, supported 2 feet at each end
swan for mj bands is to provide better seal
t tape is wrapped around 3 times minimum on threads
for 3/8" concrete anchors, drill a half inch hole, for half inch concrete anchors, drill a 5/8" hole.
expansion tool for uponor is supposed to be greased every time the head is switched
use grinder for large plastic pipe but sawzall for smaller plastic pipe diameters
you never want a pipe to rollercoaster (dip in middle), you always want it to snake (dip on its side)
venting maintains atmospheric pressure
level every fitting while securing it to pipe.
6 water closets max on a 3 inch vertical stack, 2 water closets for a 3 inch horizontal branch
grind ends of pipe to make even before grooving so it sits flat against the groover
groove coupling gaskets and split flange gaskets have a line marked on it to show where to grease
consider insulation size on both sides when answering total pipe size for a heating system
evenly tighten both sides of an mj band until snug
pex has to be supported every 3 ft
regular trap arm can only change 135 degrees before venting
don't use a 90 on its side for drainage systems (or avoid)
