Hi,

I'm looking at several granny flat constructions right now n notice there are a couple of things which are "strange" to my untrained eyes. Hope someone can answer:

  1. I notice Pex pipe is used instead of copper for plumbing inside the granny flats. Is it the new "normal" nowadays ? My old house uses copper btw

  2. Internal door openings only have 1 jack stud. Is it normal. I thought it's normal to have 2 jack stud to hold the header ? Is there any problem if there is only 1 jack stud ? Is there any reason to have only 1 (if it's to save on material it does not make sense because 1 piece of timber is only 20$ in Bunnings )

Thank you

    "Plumping" Fat chance you'll get the right answers for that.

      They look "easier" to run/wire around the house but not sure about the longevity. But more than 1 builders use it so I guess it's fine.

    Plastic plumbing pipe is the new normal. Cooper is to expensive and much harder to work with.

    Studs? Maybe it’s a newer standard for non los bearing walls?

    1 stud per side of the door may be ok if the wall isn't load bearing.

    Is there a lintel above the door opening, or just 2x4?

    Plumbers use PEX these days. partly due to costs and the risk of copper being stolen.

      It's not even 1 stud per side, it's 1 stud on 1 side only, the other side does not have jack stud. And there is no lintel above. Cheers

    ChatGP answer:

    As an AI language model, I can provide you with some information regarding your questions, but it's important to keep in mind that building codes and regulations may vary depending on your location. It's always a good idea to consult with a licensed professional for specific advice and guidance.

    Pex pipe is a type of flexible plastic pipe that has become increasingly popular in recent years as a substitute for traditional copper pipes in plumbing systems. Pex pipe has several advantages over copper pipes, including lower cost, easier installation, and resistance to corrosion and freezing. However, some people still prefer copper pipes because they are perceived as more durable and long-lasting. Ultimately, the choice between Pex and copper pipes depends on various factors such as personal preference, budget, and the specific needs of the building.

    The number of jack studs needed to support a header depends on the size and weight of the header and the load it carries. Generally speaking, a header that spans more than 6 feet or supports a significant amount of weight will require two or more jack studs to provide adequate support. However, for smaller openings, a single jack stud may be sufficient. It's important to follow the building codes and regulations in your area to ensure that your construction is safe and structurally sound.

      Internal doors are often 820mm wide, so under 6 feet. US standards (ChatGPT answer) might differ from AU one though.

        looks like someone knows how to cut and paste

    I've heard stories from plumbers saying that rats in the ceiling will chew into the pipe to keep their teeth sharp then you have a leak with no waranty. Same as leave a car in a shed with rats for 6 months and see how they chew through all wiring in the car.
    Can't remember why but none of them trust bunnings shark bit either it wouldn't last their 5 years warranty for some reason.

    On the doors every frame I've seen has 2 or more studs depending on where the door is.

      Plausible scenario … Guess I should put some kinds of pet control in the ceiling annually. Cheers
