Arrived on site and met with Mike. Explained that existing manabloc was leaking at the connection from the main water supply. Turned off main water shut off and removed existing manabloc connections. Removed mounting hardware from old viega manabloc assembly and installed new manabloc assembly in the same location. Reconnected all cold and hot water connections. Restored water to unit by turning on main water shut off valve. Restored water to each fixture by opening isolation valves on the manabloc. Tested for leaks. No leaks present. Tested function of all fixtures in the house. All functioning properly. Thank you for choosing CPI plumbing and heating!
