Replaced a defective tank. New tank was easy to set up (pressurize) and install. No leaks!Instructions are clear. If you have never done this before, suggest you watch a couple of 'plumbing how to' videos.

This is a nice tank, and it has a built-in window that screws onto the air nozzle that you can simply look at to see if the bladder has ruptured. The tank should be installed with the piping connection facing up. You will need some type of bracket to support the weight of the tank plus water. Do not forget to inflate the bladder to match your house's water pressure. This size tank is probably only needed if your water heater is 75 gallons. The 2-gallon version is suitable for most residential applications. The pressure should be checked yearly. My previous expansion tank had gone bad, and my wife always asked why our front-load washer made so much noise when water was being added. That was why. After installing the tank, the noise went away.Country of Manufacture: USA

The tank works great and is very easy to install. I didn't need the instructions but for anyone who does, they are very well written.
