Checked customer complaint about a clogged sink. The customer had a clogged sink that she wanted to have cleared. Presented customer pricing to perform a diagnostic on the drain. After pricing was approved I laid down a rug to protect the customer’s floor from damage. I removed the drains p trap and discovered large quantities of egg shells. Presented customer pricing to replace all of the under sink waste pipes. After pricing was approved I removed the existing under sink waste pipes and basket strainer. Performed installation of the new basket strainer and under sink waste. Performed drain test with the customer. I poured large quantities of water down the drain to test for clogs and leaks. The drain performed as designed and there were no leaks when last checked. The customer was happy the leak was fixed. Thank you for choosing CPI Plumbing and Heating.
