I paid a lot of money for it... all the little pipes were constantly getting cut and water would start running uncontrollably... I had to call a plumber three times to connect it, fix it, and finally install a switch to isolate the water so we wouldn't flood... luckily, the service sent some extra pipes and I think the problem is finally solved. I didn't expect so much trouble... except for 2 small tubes for the connection, it didn't come with anything else.
