10/23/2020 Confirmed with customer that mainline was backed up when flushing toilet sinks were gurgling and kitchen sink drained slow. Drain line for toilet and kitchen sink are back graded, gave customer price to repipe drain lines in crawl space. Pulled toilet and used cable down drain line retrieving hair and feminine products. Drain line is still backed up so I added 50 more feet to the cable and drain line opened around 120 feet after retrieving more hair and feminine products. Set toilet back and tested multiple times verifying proper drainage with all fixtures in the house. Will give estimate to camera and locate drain line outside building. Thank you for choosing CPI Plumbing and Heating.
Day 2 completion
Customer called in with a possible leak on his main water line. The utility company had let him know that the usage was much higher than normal on his water bill. Inspected the outdoor piping and isolated between the home and the meter. The meter stopped spinning. The main shut off for the home is inside a meter box just outside the foundation. This indicates the leak is inside the footprint of the home. Entered the homes crawlspace and immediately found the source of the leak. The homes main water line is leaking from a hole in the pipe just inside the foundation of the home. Provided pricing to repair the leak. The customer accepted. Shut water off to the home and bled pressure from the system. Cut the existing main water line and installed a new coupling. Restored water to the home and inspected the repair. The repair is working as designed with no leaks present. Thank you for choosing CPI Plumbing & Heating!
I provided and installed a new pvc shower drain for the master bathroom shower. I relocated a 1/2 inch copper water line in basement bathroom ceiling. I added water and drain piping for an additional lav sink in the basement bathroom. I tested all installations and everything is in great working condition at this time.
