Oasis put in a water softener unit in a rental of mine. Oasis not only did a great job sweating the pipes and installed the system but the technician noticed I needed a working shut off valve and installed it as well - no cost. This is a professional plumber who gives a great product for the best price. Shop around you won't find better. Also I called the office person Bailey maybe five times with questions. Had lots off issues with older building. Bailey got back to me after consulting her plumbers with professional answers. Informed professional great price . I'd hire this company again.
