Thanks for your kind words. They sure help temper the disparaging comments made by some others. I encourage you to start loading some of your own videos, as I would love to learn from you! As for that Boston loop, all I can say to do is Google the term and see if anything is written about it. I'll go try to do that now.

Yes. I have done that on occasion. The code sometimes calls them loop or island vents. Grab a copy of a code book from a plumber to see it. It is impossible to describe in this space.

Fair enough. I'm all for proper installation and your solution is the most stringent in this situation. One that I would agree with................ For the person that would go the extra mile, checking with State and local codes would benefit someone on knowing if an installation is legal or not.

@wildwoodtop i may be misunderstanding the question. but i am a plumber here in north carolina and the maximum distance from the toilet to the vent is 12 feet here. It is determined by the trap size. 1-1/2" is 6ft 2"is 8ft and 3" is 12 ft. Hope this helps.

@wildwoodtop Most jurisdictions here in the USA only permit 36 inches between the toilet and it's vent. There can sometimes be exceptions.

@midlantic1 13 жыл бұрын

If it's just a lavatory with an 1 1/4" trap you can drin it right into that tub vent, thus making the vent for the tub a wet vent. The code requires us to increase the pipe size by one size, in this case to 1 1/2" which is the size of the vent in the wall. No need to back vent the lavi at all. The national standard code allows us to vent an entire 3 piece bath on an 1 1/2" vent

@Skorlang Not too long ago in Ohio you could do that. It would have to eventually tie into a 3-inch vent or larger before exiting the roof.

You can't assume wet venting is permitted in all states. For many, many years it was prohibited in Kentucky.

I think it's a bit misleading saying that the plumbing code requires that the vent pipe connection to be "right about here" since the connection can be made anywhere higher than original "problematic" location.

Fair enough. I agree with that statement as well. Many municipalities allow the homeowner to do their own work...... Is it safe? In most cases, it might be since the Jurisdictional Authority has to inspect the installation anyway. Just trying to give my two cents in for good general tips.

Get a group of drain-cleaning plumbers together and they will lobby hard against many of the wet-vent proposals. Gunk from other upstream fixtures has clogged many a downstream one in wet-vented setups. I am not saying all setups are bad...... I have two code-approved wet vent situations in my own home.

@askthebuilder 15 жыл бұрын

In this case it was so easy to tie into the existing vent line. The biggest problem with mechanical vents is they can fail. Traditional vents work all the time unless some idiot drops a tennis ball down the roof pipe. I've installed mechanical vents in an island sink and they are suitable, but no real long-term substitute for a traditional gravity vent. Your mileage may vary.

@askthebuilder 15 жыл бұрын

Steve, I have to disagree with you until you provide the documentation to prove your statement. *Many* states allow homeowners to do their own plumbing. What you're saying is that the average person can't go do plumbing for others without a license. The person clearly stated this was an owner-occupied situation. Tim - Master Plumber

@texmexmaniac1 15 жыл бұрын

I've got an easier solution: Just run a trap arm (or dirty arm) off the vent at 18" above the floor and stub out for the lav drain. The plumbing code will allow smaller fixture unit traps to "dump" over larger fixture unit traps. In plumbing terms, we call this "wet venting". It will eliminate the need to run an independent vent for the lavatory. Saves time, money and space. Steve / master plumber

@EdwardMarshall1982 14 жыл бұрын

@AsktheBuilder Or if your lazy like me. :) You can always run a studor vent, but keep in mind that they need to be installed under a cabinet and out of the wall. This will give the same aesthetics without having to curse yourself when you have to replace it.

Great question Ralph! Here's the answer. Can you give me examples of mechanical things that have *never broken*? Traditional vent pipes open to the atmosphere have nothing in them that depends on moving parts.

@ralphadams9113 9 жыл бұрын

I suppose anything can fail, but I've installed a few of them over the years and never had a problem yet. They are code accepted in my area and I expect that they wouldn't be if they were prone to fail. Oatley makes 'em so I trust 'em.

@askthebuilder 9 жыл бұрын

***** You bring up the exact reason why I don't like AAVs. I think many, including code officials, tend to look at the time line too myopically. My experience of working on houses that were built in the late 1800's in Cincinnati, OH that had nice 4-inch cast-iron vent lines that were wide open is jading my opinion. I know the AAVs will fail in time. That's a known fact since all mechanical things fail. I believe they're in the code because they save time and money. Kenny Chesney wrote a song about this, "Only time will tell, but it ain't talkin' "

Again, checking with State and Local codes will determine if the homeowner has the right to undertake such a task. The Uniform plumbing code clearly states in Chapter 1 Administration; Section 103.1.1 of permit requiring for plumbing installations. The protection of the public health, safety and welfare from potentially dangerous results from improper plumbing situations is the utmost importance. Only experience licensed plumbing contractors are properly trained to install such plumbing...
