      It's not about what you think is needed.
      It's about what the code dictates that is mandated.
      That's the difference between a credible contractor, and a fly by night operator that takes your money and runs.
      You would be a fly by night operator that no one should trust.

    Where I’m at (Cincinnati) clean outs are required under the sink and at the wall. I guess not needed here but I like it as a cheap way to get piece of mind; allows you to quickly clear the vent portion from either direction in case of a blockage.

    The top of the loop vent should be assembled with two 45 degree bends with a single 90 degree at the top (i.e. between the two 45s). This is so there is no horizontal section that could hold any standing water/gunk should the vent flood. What is shown here has two 90s connected with a short straight stub. Probably not a big deal, but not really the officially correct way - and may not pass code in some areas.

    This is such a clever solution for that problem. It also seems like it could be useful for a sink below a window, and if that bow is run above the top of the sink / countertop height, then water cannot back up to the top of the bow -- the sink would overflow before that happens. (I'm here looking for the best solution to my sink below a window venting problem. :))

    • @MyFortressConstruction
      @MyFortressConstruction 3 місяці тому

      The majority of all houses that have a sink window, still run the vent horizontally until they can go up around the window. It's possible that you have an alcove sink with walls on three sides and windows covering every wall, but with a little planning you could still leave a few inches for a pipe to go vertical before the corner. This type of island vent is still not preferred as you could get back up at the wye above the main drain and not have the ventilation you need. Another option is an AAV, but those aren't allowed in most, if not all, municipalities.

    the kitchen sink venting threw me off a little why not run a studor vent?, instead of this horse shoe bend?, also this makes it incredibly hard for a plumber in the near future to snake that kitchen sink if it ever does get blocked up, I see no santee cleanout installed anywhere on this kitchen sink line, which would make for a disastrous and problematic fix in the near future, in my opinion every fixture or drain in a modern home should have a cleanout installed.

    @This Old House, nice presentation. Seems to be missing the clean-out fitting in the air vent line under the sink. What is the homeowner to do if the short section of the vent pipe between the flooring and the common drain pipe becomes blocked? The ensuing air lock will fowl the normal draining of the sink. Add to that the vigorous action of a garbage disposal and the stuff coming up in the sink can look disgusting. Especially if during the prep for a dinner party with the hubby's boss.

    • @DDunc1020
      @DDunc1020 2 роки тому +1

      Its not called a hose, its a pipe. They are very durable piping, the fittings on the other hand might be an issue in the future. In cold weather in MA you could have them crack, in FL in the heat you could have them degrade from the heat if out in the sunlight. It all depends on the installation doing it the right way. Copper still corrodes, cpvc still cracks. Nothing will last forever. The best answer to the pex after all that said above is, the less fittings the better.

      It is common that Studor vents are not allowed on new construction. The pitfall of a Studor vent is that the home-owner doesn't know what they even are, and doesn't know to inspect them and replace them. They are good for a retrofit, because it is better than no vent at all, but not good if the home owner doesn't even know they exist. Plumbing vents in new construction usually need to be done right the first time, so they don't depend on moving parts that require maintenance.

    • @YouToobeism

So.... it can't even be assumed to be dry vented even if your suggestion of code violation was valid.

      Vents are required at all fixtures, otherwise the traps that keeps sewer gasses from rising out of the drains do not work properly.

      How about YOU slow down? Of course a vent is required. And the fact that you're still using "rocket science" as a barometer shows your age. There are things MUCH more difficult than rocket science. In fact, rocket science is rather mundane in the 21st century.
