When I rerouted the sump-pump discharge line in my basement, I wanted to eliminate the noise. The original installation used wire pipe hangers nailed into the overhead joists. The noise of the pump running, which was followed by a loud bump when the pump shut off, was very annoying — especially at night.
In the new installation, I suspended the entire 50-ft. line from the joists using rubber tie-down straps (see drawing). The straps come in various lengths, and the attached S-hooks make them easy to install. Each strap only requires a couple of screw eyes.
I put the straps on 32-in. to 48-in. centers. They easily support the 1-1/2-in. pipe, even when it’s filled with water. Wrapping the straps around the pipe provides enough friction to keep the pipes from shifting while permitting enough movement to accommodate the changing water pressure.
