Water Group 7 will patiently sit down and listen to you, in order to achieve your specific water filtration requirements. Jeremiah also took the time to inspect potential trouble spots, and provide the recommended rectification. In our case, we were very pleased that Jeremiah's brother installed a sensor, just in case there's an accidental back flow of water onto the cabin floor. This was extremely significant to us as living in a condo equates to being absolutely vigilant on any potential obstacle. Professionalism, punctuality, integrity and cordiality, is what sets Water Group 7 apart from all the rest. We highly recommend this fine company.
