Perfect solution. I was hearing what I thought was a leak for weeks and couldnt find it in my 4000 square ft home. Then i went over to the water heater and heard the old pump rattling and realized that it was the cause (I confirmed it by shutting the power off to the pump...). Once I shut it off, voila, sound of running water disappeared!. The day i got the cartridge I took it out of the box and within 10 minutes the old one was replaced. 4 screws and a nut driver, thats it. Very easy install. Make sure to shut water and power off before removing any screws. Bring a bucket for any water in the return line to dump into.
