We recently ordered this system to replace our current system of another brand. The leak stop and pressure regulator were the two features that set this system apart from other brands. Our plumber installed it and discovered a defective part. (Conceivable the part was damaged during installation; we could not identify what was wrong with it.) When I called customer service, they apologized and literally had a replacement part in the mail within an hour of my phone call and it arrived in two days. Their communication was top-notch and the replacement part had the system working in five minutes. Very happy with our purchase!
