Replacing your discharge pipes for spring is quick and easy. First, remove the diffuser from the stub close to the house. Then, screw in the long discharge pipe. Making sure the screw threads match up is important. If you have flexible pipe exiting the house, you can simply bend the pipe to achieve the proper angle. If you have rigid pipe exiting the house you’ll need to elevate the far end to get the threads to mesh. Finally, add the diffuser to the far end of the discharge pipe and you’re done.
