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!

Arrived at customer’s business to a clogged urinal. I tested the other fixtures in the bathroom and the only affected fixture was the urinal. I vacuumed out the remaining water. Attempted to flush the urinal and it backed up. Shut off water to urinal, vacuumed out remaining water, opened clean out cap. Found large blockage at cleanout cap. Scraped away blockage and then began drain cleaning through the cleanout. Felt some resistance on the auger at about 3-5 feet. Removed auger and replaced cleanout and tested the urinal drainage by flushing. The urinal was now flushing properly. Flushed the urinal 10 more times and it drained properly each time. Cleaned up work space. Discussed repair with store manager. Thank you for choosing CPI Plumbing and Heating.
