    I installed a new sump pump in my moms house recently. I had to make a hole through the outside wall to run the drain outside as there wasn't an existing hole. It's a split entry home so the block wall isn't very high. I had to go through the sheetrock and out through the siding with the 1.5" pvc drain.

    My question is, how do I secure that pipe somehow? I need a way to clamp it to the wall so it's not able to slide in and out.

    Any suggestions?

    Thanks.

    I'd use caulking or expandable foam in the 2 holes where the pipe enters and exits the wall.

    I need something more rigid. It's in a place where it could easily be bumped and there's no caulk in the world that's going to keep it from sliding. The fact that the check valve is a flexible rubber coupling makes it very easy to move as well.

    Just had a thought.

    Screw a 2x4 across the studs that are running on either side of the pipe and just touching the bottom side of the pipe. I can then use a single or double sided clamp to hold the pipe.

    Sound logical?

    While you are still messing with the piping...
    Get rid of the rubber check valve - replace it with a hard plastic one...(unless you don't care if your mom's place gets flooded when the check gives out and the sump starts spraying into the basement)
    For anchoring, you can use 2-hole straps and bracing as was suggested.

    Try a suspension pipe clamp....

    OK, for some reason the link keeps getting blocked. Do a search for suspension pipe clamps.

    Apparently this link isn't working. Can you spell it out or re-link?

    Just wondering what you mean. Are you saying the rubber may crack/split/separate, or that the hose clamp would loosen up?

    Couldn't you say the same about a fernco rubber coupler as well then?
