Installer "Junior" was called to repair the main water shutoff valve to the house. My wife and i had been discussing the need for a water softening system (very hard water in our area). Junior determined that repair of the valve would require damaging the foundation (it was originally installed too close by the builder). He came up with an alternative method for a shutoff valve - one that would be part of, and work perfectly with, a water softener and filtration system. After review of the Halo 5 system he recommended, he set about the task - on a miserably hot and humid day. He worked for 5 hours under miserable conditions, and did the job beautifully. Although the system's brochures say improvement would not be noticed for up to 2 days, it was immediately apparent, and has improved. We love it. Good work by Juan C. (Junior) and Red Cap Plumbing.
