Product review (2 stars): the installation is fairly easy. Sadly
I purchased this an installed it myself with no problem using basic tools.  I am fairly handy but by no means a skilled handy person, so if you can read and follow instructions, the installation is fairly easy.  Sadly, within a month the pump failed and I was back to the drawing board.  I'm not sure if it was a cheap part or defective, but either way, I can't recommend it.  I give it two stars because it arrived on time, and was as described.  It was also priced better than other sellers, although this may be due to it being an inferior product- I don't know.
