Sump Pump Discharge Piping

I just finished up my sump pump discharge project. I finally got around to ordering two check valves for PVC pipe from Amazon and they arrive yesterday. I had almost everything I needed, except for a ten foot length of 1 1/2 inch PVC tubing. I got that yesterday while I was picking up supplies for another project. I’ll get to that later.

I have two sump pumps – one for each section of basement. I used to have each pump attached to its own small 1 1/2 inch tube that would exit the house at different points. After thinking about it for a while, I decided that connecting both pumps in the interior and have them exit the house at one point would be better. From there, I would have the exit tube attach to a large 4 inch corrugated pipe. I picked up a 100 foot long one and that I could pretty much run anywhere with little risk of it freezing. Those small pipes – no thanks. They freeze every which way.

Take a look at the pictures I just took.

The way I have it set up is both pumps pump water into their respective pipes. If they are both running at the same time, hopefully the water will find its way out the exit pipe. If only one is running, the check valve attached to the PVC pipe of the other pump will stop the water from traveling through that pipe into the other section of basement.

The flexible pipe comes from the sump pump. From there, I have it attached to the PVC with a rubber adapter. The adapter increases the size from 1 1/4 inch to 1 1/2 inch.

This is a Zoeller check valve attached to the PVC pipe. People seem to say good things about these check valves. They’re supposed to last a long time and they’re allegedly durable. I’m looking forward to a chance to seem them in action. Setting systems like this up is quite fun.
