Checked customer complaint about a clogged main line to their septic tank. Presented customer pricing to pull the septic tank lids and check the inlet baffle. After pricing was approved I pulled he tank lids and discovered a blockage in the inlet baffle. Presented customer pricing to attempt to remove the blockage from the inlet baffle. After pricing was approved I removed the blockage and the line drained down. I ran all of the fixtures in the home to test for leaks with the customer. The drains performed as designed and there were no leaks when last checked. The customer was happy the line was cleared. CPI does not warranty or guarantee drain cleaning. Thank you for choosing CPI Plumbing and Heating.
