At my age, I am getting to where I do not wish to consume a lot of chlorine in my water, so I called Clearwater Systems of Lynden, Washington to install a reverse osmosis filtering system for me. The installers were very nice people, and they did a good job overall. Supposedly, it was a normal thing to put the bulk of the machinery and filtering system in the crawl space, but after that was done, it seemed to not be very practical considering the filters need to be changed every six months. So, the whole unit got relocated to my utility room, with the filter high enough that I can change it standing up. The wrong filter was also installed, but that got corrected, and now the unit seems to be working fine!
