Do not go with a Mcclean water softner. After six months my water softner began to leak. I've tried several times to get their "chemical engineer," to look at it. He now doesn't even return my calls. I am unable to reach the company. So now after only three years I have a water softner that not only doesn't work but has caused rust spots on my washing machine. Go with a company that will stand behind their product; Sears.
