Grades of Vents - Page 2 - Plumbing Zone

the cdn code book says nothing about grade for vents, but the inspector wants 1/4 per foot. And they will fail you for it.

M5Plumb · 08-25-2010, 03:53 AM

two rules, 1/4" p/ft and payday is Friday.

well i found out today any vent not tied into a wye is not a vent??? effn inspectors are stupid. even with 1/4 per foot he calls it a flat vent

says it has no washout so backups can clog it

Illinois Plumbing code states 1/8" per foot toward fixtures. States they must be "installed to drain back to waste"

Bottom line, IMO, if your vents are graded any old way or flat your work is going to look like crap.

I drill studs at 42", 42 1/8", 42 1/4"....... Sets the grade nice.

You must use a super deep seal trap to pick up a kitchen sink

Sorry to inform you Mr 2 Code. Your vents are not to code.

On standard 16" stud spacing your vents only have 3/32" per foot of fall. A little shy of the required 1/8" per foot. I mean if your gonna correct people and all.

Just sayin'

GREENPLUM · 08-25-2010, 09:43 PM

you call it a vent, i call it a drain for mother nature,

the vents should have fall,

above the minimum

sometimes

Give me a break. I'm just saying, if your vents are flat, zero pitch, I feel the spirit of the code says your wrong. If they're flying, your wrong and your work is going to look like crap. Give them essentially the same pitch / grade in the opposite direction and I assure you the inspector will be pleased.

BTW, I get alot folks that think the name i chose is pretty cool. And yes, it does put a little stress on me to do the right thing.

. Unfortunately, I don't have the all the answers, that why I come here for pearls.
