I've been futzing with this sink for some time. I got a bowl from Home Goods, got the pump from the junk bin at Bacons and a chunk of roofing rubber from Ace Hardware. I got a 5 gallon flexible water tank from Walmart. I hooked everything up and the pump didn't work. Hence the reason it was in the junk bin. I ordered a rebuild kit from Imtra, an internet marine store. That solved the problem. Now you can wash you hands!
