So I guess I should be asking if did they sell these pop ups without water pumps? Hooked up a hose to city water port and facet works fine, but when I lift sink unit up to in spec facet area there's no switch or anything. Run hose back and it leads to outside city water port. So what's up with water tank. How did they expect people to have running water if you didn't have city water hook up? Just checked again and these actually two hoses going to the faucet one from city water and one from holding tank but no pump anywhere that I can find. Am I missing something? Why would someone spend all that money when new not to have water?
