10/21/2020 Confirmed with customer that dishwasher would not drain. Removed air gap and dishwasher line from garbage disposal cleaned lines. Hooked air gap and drain line back up tested function of dishwasher several times Verifying proper drainage. Found Quest water lines for house that have been recalled will give pricing to repipe water lines for house. Existing vapor barrier, flex ducting, and electrical wires are severely compromised to due to rodent issues. CPI Strongly recommends an exterminator be called immediately to assess conditions. Thank you for choosing CPI Plumbing and Heating.
