Spent the day looking at what it would take to replace the Headhunter, when it dies, with the Grundfos pump. The Grundfos pump is about the same width, not quite as tall, but 5 1/2 inches longer. As Tom said some replumbing would be required. The connection points are in good positions that will allow just minor replumbing. It also looks like raising it off the floor about an inch to inch and a half would make the fit easier as that would allow it to miss some existing piping. One of the advantages to the Grundfos pump over the Headhunter is the availability of rebuild parts, as well as the price. The gpm specs are almost identical.
