I think the dupes won't fill the filtration system with sand until there's water ready to be cleaned. Your pump appears to not be pumping any dirty water in.

If you look at the picture everything is all set and I have sufficient energy as well. Also the pump is in the contaminated water that needs to be pumped. They usually send the materials first before the machine can be used or how else is it going to work without the sand first being in there?

Could this be a pump issue then and not a water purifier issue. I would need a dev to confirm, unless they gave us access to console commands to try it out ourselves

I think it's a pump issue and a purifier issue. The way the purifier works is it doesn't ask for sand until it has some contaminated water at its intake. It probably should. Your pump is also not working. That's why the purifier says Empty Pipe. Sometimes the pumps stop working if they switch from clean to dirty water. Usually saving and reloading the game or deleting and replacing the pump fixes it.
