I never knew they made a grade level. Thats awesome 👌

I've heard that argument against that much fall however being a service plumber I've never seen 1/2 or more fall cause an issue.

agree and being from the upc code I hate hearing guys say you cant have more than 1/8 inch per foot we gotta have 1/4 min. but i think they knew what they were doing when the called for minimum fall there is no maximum fall and I think there is a reason and that reason is excess fall hardly ever causes issues . I still think 1/8 inch inferior to1/4 inch per foot unless youve got bigger pipe like 6 inch but also on super long runs it would be too deep

@@jeffreyplumber1975 While there's not a stated maximum, there's footnotes which note that excessive grade can cause the fluid to outflow the effluent and leave effluent behind to sit and create blockages over time. So while sometimes you have to do what you have to do, you generally want to keep from being ridiculous with it. As an installer, to nvrdwn's point, I've never seen a situation where I've had to have 1/2" of fall or more. Maybe once ever on a reno?

Same here. I’ve never come across a job that stopped up more often because of too much fall. People say it because there’s logic to it but never think it through. If it was a problem, then every rough I’ve done that had an offset with 22’s would have issues. Theres also lots of places where I’ve had to roll a 90 to some oddball angle to connect to something else. This would have issues. If it is an issue, where does it change back to being okay. Is it vertical (for non plumbers, in plumbing vertical means anything from 45 def to plumb). Not to get into too much detail but there’s definitely solids that would stick in a 45 degree pipe without water. Is it only limited to sewer? With how luch grease goes down a kitchen sink line, I want that thing to be moving as fast as possible. I don’t want to give it any more time to solidify. I’m long winded but point being if this were true we’d have a lot more problems than we do.

Commercial Plumber here I've been installing large(20 story)multifamily buildings over the past few years. One of the main reasons you don't want too much fall in a system is due to the venting needing to have the proper amount of air pressure so that the water in the ptraps are not sucked out, and there is still enough air flow to properly vent the system. If you think about a 200 foot run of eight inch pipe that is at a 1/2" vs 1/16" that would be a huge difference in not only the predicted amount of force at the next joint requiring a ridiculous amount of extra support to stop the potential force on that 90(that happens also happens on storm drains that use a short sweep to catch a vertical) or it will pop off. And of course now you have a crazy amount of air pressure going up pulling every p trap out for the next 4 floors(idk how many that would pull tbh but definitely that example would ruin a plumbing system if set at that kind of grade because of the venting.)

@@lionheart1126Any water in the line should suck from vent, if it doesnt it’s improperly vented. It sounds like you’re talking about right past the trap before it flattens out. Yes you don’t want that too sloped. As for the rest Water doesn’t fill the pipe as it moves so it only really pushes air in vertical pipes. A pipe graded at 1/2” wouldn’t push or pull air, it would flatten out. Also any vertical pipe would gather much more momentum than horizontal. So are you not allowed to install vertical pipe because it would be too hard on 90s. This is why you use long sweeps or preferably 45s. All that momentum moves on down the pipe. Do multistory buildings not use vertical piping?

Always run at 1/4 per foot - it covers everything from toilet to kitchen drains with zero issues - and the trap to vent distance always passed every inspection I was ever part of.

Scoped a line on a brand new 1.2+ million house the other day with a 7 foot long belly in it 🗿

always do about an 1/8 or a bit more of fall on it. The standard here is every 10’ of pipe we use is about 2-1/2 inches for fall but doing ground roughs it’s hard to keep it that way unless you want out of your ditch lol.

Something else to consider is that the amount of fall has an effect on your venting distance. Basically, a trap arm sloped at 1/2” per foot will result in no vent at the trap at half the distance of a trap arm sloped at 1/4” per foot. In every code I have read, all drains sized below 3” must have 1/4” per foot slope - not an 1/8” and not a 1/2”. Everything 3” and above can be sloped from 1/4” to 1/2”. However, if you are running a trap arm to a 3” or 4” trap, you need to stick with 1/8” to 1/4” to remain within the maximum venting distance from the vent to the trap.

In nyc 2 1/2” or less 1/4 pitch 3”-6” 1/8 8” or larger 1/16 that’s the minimum

Thank you for this 👍🇺🇸

Good point on the trap arms. ICC codes lengths seem to be based on 1/4 "/ft. That would be the max pitch, unless maybe you decrease the trap arm lengths...

Thanks, you too!

Great info. As a home owner I am always looking for a more complete understanding.

Roger. right now I'm having trouble with a city inspector understanding what your talking about in this video. job site has sewer run about 400' to city main over a big hill. I'm wanting to do step down, city is say No, not code.

My outhouse has 180° fall, it has NEVER clogged up, so that tells you too much isn't always bad!

On a horizontal pipe you need to monitor the weir the lower end can't be to low or it will cause a problem the water will not flow it will surge. Pulling a vacuum and sucking the water out of the traps. Do it right or don't do it.

i measure based off how fast the bubble reaches full bubble. at a quarter the line should split the bubble. if it goes full bubble it needs to reach that point very slow. that tells me its a quarter plus.

Find Julius Ballanco's Plumbing & Mechanical article "it's the solids that run away". Out there on internet. Too much pitch?

Thanks for this knowledge, Rogger.

I remember someone told me to much drop could create a vacuum and suck the pee traps dry

Does grade matter on vents? Air is just air right? Can't you just make the vents level? I always give them an 1/8 per foot because that's what I was told

Initially, I was taught that too much fall can cause an issue, but pretty much all of the old head/supervisors have told me it's not an issue. Pretty much been told "cant have too much pitch" In my head, this makes sense, because here we have houses built on huge hills with extremely steep driveways; wouldn't the main sewer line leaving the house just be soaring at that point? And it doesnt seem to cause problems. So Id be curious if anyone has additional input on this.

I think the more important consideration is that it's easier to add grade than remove it without botching a system or creating a headache for yourself. Staying closer to minimums allows for digging shallower trenches for less hassle with clay and hard ground, or allowing for higher ceiling if running under joists, or an ability to run in joists when more grade wouldn't give you enough room allowing for more efficient routing of pipes and avoidance of other trades like HVAC guys or preventing having to box out a section. While in theory fluids can outflow effluents with more grade, in practice this doesn't happen very often. However, there are countless arguments to be made for staying near or slightly more pitched than the minimum purely for a better designed system and better build for the client. Any plumber who just adds grade simply because he can add grade and it won't block up down the road is just an ignorant tradesman who's ignoring the multitude of other reasons for doing so. If you're adding grade there should be an actual reason for doing so beyond "I felt like it" because that's just a lazy attitude.
