At first I was concerned about install. I waited too long, eventually my husband did it, ee didn't even have to turn mains off as we have valves on our pipes too shut off water easy, husband was dubious at first, but he and I was over whelmed how easy to install, and amazed how nice the water tasted,no more buying, plastic water in bottles, Yes this has made our life a whole load cheaper, easier, convenient llove it, love it so much !!!!
