Performed safety and maintenance inspection. Checked all bathroom and kitchen drains and water supplies. Tested hot water to ensure it was being delivered at a good temperature and time. Checked washer drain and supplies, dryer vent and tankless water heater supplies. Checked crawlspace, no signs of any water or leaks. Flushed the tankless water heater using a vinegar and water mixture for 20 minutes. Cleaned cold inlet filter. After disconnecting the pump I used to clean the tankless, I ran cold water through the hot water line into the sink to rinse any vinegar that may have been left in the tankless. Ran water for 5 minutes until the water had no vinegar smell. Spoke with customer about having the supply lines for the bathroom sink replaced with stainless steel braided hoses as the current ones are plastic. Also mentioned that the shut-offs for all fixtures are gate valves and will need to be replaced with ball valves. Customer renewed their membership. Thank you for choosing CPI!
