    Hello Everyone, I am building a concrete home. Plumbing is being handled 95% by a well respected local plumber. The home is three stories. The main toilet waste pipe comes into a lowest level room horizontally from above, makes a 90 degree straight down turn and drops to the slab below where it makes anther 90 degree turn and leaves the house. When the toilet above is flushed the resulting noise is unacceptable. Pipe is PVC and will live in a built out section of wall that will conceal it and other utility pipes. There is room within for most any kind of sound deadening product.

    I am looking for best practice noise abatement suggestions. The room that this pipe passes though is a bathroom for a suite on the lowest level. Waste flows through this pipe from two upper levels.

    Thanks in advance.

    No-Hub Cast iron is much quieter.
    If you stay with PVC, You may be able to stick tape on the pipe that reduces sound transfer.
    The layout, a horizontal does make for some splashing. Insulation on the walls covering may help too. And sometimes, dropping from thirty feet is just noisy.
