Be careful when advising someone to run drains without vents. What is legal in OK may not be legal anywhere else. We go through a lot of things here. Most of us try to tell owners to check their local code. As I said before, we do not want an owner to do a project, ask for an inspection, and the inspector says, “What is this?” The answer then is, “I was told to do it this way.” Where I am, we cannot do what you have proposed. Nor can we use AAVs without receiving a “papal dispensation.” I don`t think I fully understand it, but on the one hand, you can guide your sink around the walls of the first floor until you get to a place where you can fall into the basement without crossing the stairs. You are allowed to use automatic air intake valves for ventilation now in NJ (not on the duct ejector) Must be a Studor vent, not the little nerds. I always thought they should remove the word “vent” from the codebook and replace it with “pressure compensation pipe” because that`s what it is. It is used for convenience. But it is a mechanical device that relies on rubber springs and seals, so almost by definition, it will fail at some point. In addition, it prevents negative pressure in the drain, but does not relieve overpressure, so its usefulness is limited. “AVAs are something you use when there is no other option” Is there really “no other option”? There is always the possibility of operating a device vent, it is only a matter of knowing what it takes to do it. e-plumber ———————————————————————————————————————————– “The society that despises excellence in plumbing as a modest activity and tolerates misery in philosophy because it is a sublime activity will have neither good plumbers nor good philosophy: neither its pipes nor its theories will hold up.” – John William Gardner 08.10.1912 – 16.02.2002 Repair your pipes or theories plumbing fixtures.” – John William Gardner 08.10.1912 – 16.02.2002 Repair your pipes or theories plumbing fixtures leak as quickly as possible [www.theplumber.com] This slow drip wastes more than 7 gallons of water a day.
As for the sanitary facilities. Can`t you just follow the walls? I will install new lines and a garbage can. The problem I have is that the two stairs leading to the basement are on side C. The sewer pipe is on side B and the sink is on side C. What can I do to make a good drainage without a pipe dripping down my stairs? The basement is only 6ft high. will remain unfinished. Well, the minimum size for a kitchen sink is 1-1/2″. If there is an elimination, we always use 2″ minimum. The location on 1-1/2 or 2″ is 1/4″ per foot.
It`s a fall of 1″ every 4 feet. It doesn`t sound like a lot of pitching, but it`s what it takes. More pitch is not better, this formula is important for moving the solid material into the drain. Too much bad luck and the solids remain in the line, while the water rushes and does not carry the dirt with it. This is when you suffer from constipation. Your old drain probably smelled because there was no loop under the cabinet in your dishwasher outlet line. This is the most common reason for a stench emanating from a kitchen sink drain. If we can`t walk directly above a basement ceiling, then we walk with the walls to where we need to be. Is it a better alternative to normal pipe ventilation? Edited 1 time. No, it is subject to ventilation by the roof. Some of the AVAs have a rubber washer and a small coil spring.
When a device flows and creates a vacuum on the dewatering pipe, the vacuum pulls the seat disc so that air can enter the system. When the vacuum is gone, the coil spring pushes the disc back to its seat. atmospheric = roof – – – – – PLUMBERS “Protection of the health of the nation” I like it for outdoor kitchens. I hit an air hose that goes through the openings of your grill, which are called vents because they evacuate the system, they do not balance the pressure, any system that is not under pressure or closed will balance itself. They call it a vent because the vents “allow” a better equalization of pressure, they do not “cause” balance. If you say that, then all pipes, including drains and vents, would be pressure compensation pipes because the weight and light go up. The movement of water is what “causes” the pressure imbalance, and unless something is introduced to stabilize it, this imbalance will cause problems. Ventilation is the object that allows the pressures to stabilize. An AAV treats only one type of pressure imbalance. And your solution for an island sink wouldn`t pass inspection, but it`s a combination of garbage and vent drain, so it has a vent. This is only done internally. Edited 1 time.
In this case, the declaration continues to apply. Either there is no other option and you are using an AAV, or there really is a way to install the traditional vent, and you do not need it. An AAV is like the AAV on a gas tank, with a removable cap. A sanitary AAV can be problematic at best, not to mention the noise factor. It should be considered the very last resort. Sincerely, since this is the ONLY alternative to roof ventilation, it could probably be described as a “better” alternative. But it`s very bad. Here`s a search for a few reasons why you don`t want to use them! AAV, smell search. [www.plbg.com] – – – – – PlumbingSupply.com- Please visit our sponsor [www.PlumbingSupply.com] he lets the air in, but not out. It is a bad substitute for atmospheric ventilation – – – Noises, the previous pipe went directly through the room and poured into the sewer pipe.
That is, no matter how you probe it, it won`t properly fuel gravity because your distance is too great for the playground. In this case, you will need to drain it into the catchment area and push a shredder pump (not sure if a sewer pump can handle garbage disposal) into the sewer pipe unless you bring it closer. I suggest you hire a licensed professional to make it work properly the first time. That`s why I spent 4 years at the plumbing school and 5 years as an apprentice before I could take my master`s exam in plumbing. I charge $1000 per game. That`s about the price of a rough kitchen sink. I am in the process of renovating my house and have now come to the kitchen. My sink is on the other side of the house from the sewer line. My original idea was to move the kitchen to another room, but after a lot of measurements, it just won`t work.
The previous installation had 1 1/2 PVC in the wall with a roof ventilation line. On the way to the basement, there was no pitch in the pipe that ran through the house until it went down 90 degrees into the sewer line. I`ve always had a smell of the sink, I guess the thing never succeeded without bad luck. Vents are called vents because they evacuate the system, they do not balance the pressure, any system that is not under pressure or closed will balance itself. They call it a vent because the vents “allow” a better equalization of pressure, they do not “cause” balance. If you say that, then all pipes, including drains and vents, would be pressure compensation pipes because the weight and light go up. AVAs are something you use when there is no other option. For example, if you have a Barsink upstairs and there is no way to get 3″.
3″ to a sink does not need to be ventilated. There is no way to get your vent through the roof. An AAV should never be used unless I think it is absolutely necessary. Oh and when it comes to kitchens, outdoor kitchens with an island or bar, just walk three inches underneath, then throw 3″ x 1 1/2″ t-shirts, with a cap on top, and then there`s no vent or AAV to play with.
