Sump pump help

[Wyatt014]

I was wondering if I would be able to discharge 4 separate sump pumps with a combined GPM of 172 out of a single 2 inch PVC pipe. The pipe would run around 100 feet before it empties into a creek. Would the 2 inch pipe suffice or do I have to take them out separately?

No, I would not connect 4 pumps to a single 2 inch discharge pipe. Running 4 single pipes would be a better idea. You would need a larger pipe if you are going to connect them all together with that flow rate. A 4" pipe would handle that flow rate. You might be able to use a 3" pipe if you gate the pumps down to reduce the flow rate. I would use pressure pipe and fittings.
