Our softener left by previous owner has been acting weird for several months. It eventually died last month. We paid $75 to ask a Sears guy gave us a repair quotation of $250. In the end, we decided to buy a new water softener from Sears and install it by myself.

It is not that hard with all the pipes installed. What I need to do is reconnecting two main streams and two drains. Remember to shut off the main water supply, otherwise my front yard could be a swimming pool if something broken.

Ok! $230 installation fee is saved.
