Confirmed with customer that toilet was backed up and not draining. Upon arrival toilet had been cleared by tenants previously that day. Performed drain cleaning on toilet in attempt to clear out any remaining blockage. Used cable through toilet retrieving cleaning or flushable wipes. Tested toilet verifying proper drainage and no leaks present. Informed tenant not to flush cleaning wipes or feminine hygiene products down the toilet to help avoid filter clogs as they do not break down. Thank you for choosing CPI Plumbing and Heating.

Confirmed with customer that main water shutoff to the house keeps spinning not turning water back on. Joshua excavated area after approving estimate. Returned when excavation was completed turned water off to well and cut out damaged main water shutoff valve just outside building. Installed new 1/4 turn ball valve turned water back on at well verifying no leaks and proper function of valve. Thank you for choosing CPI Plumbing and Heating.

Confirmed with Marty that mainline was backed up. Removed clean out cap outside building finding standing water in line. Ran cable out 50 feet drain line is still backed up. Performed hydro jetting and was able to clear drain line. After drain was cleared used camera finding a belly in the drain 8 feet out. Also found root intrusion in concrete mainline at 20 feet. Line is clear past 20 feet out to city main. Will provide estimate to replace damaged section of mainline. Thank you for choosing CPI Plumbing and Heating.

Customer had mainline clog and had shut water off to fixtures. This line has had multiple clogs in the last two months. Piping consists of abs plastic, cast iron and pvc. Line is flat and backgraded from the bathroom to 5 ft before the foundation. Was able to clear soft debris clog and drain line. Used video inspection equipment to inspect line. It is draining at moment but will clog again soon. Floor drain in closet is slow draining and the wye connection that this line connects to the main has debri lodged inside and sticking out some into mainline. Could not clean this drain due to age and pipe material. Line will need to be replaced to avoid future drain outages. No warranty on drain cleaning
Coady P.
Customer reported that the shower drain in unit 102 had sewage back up into it. No other drains seem to be affected. Room is on main floor which is slab on grade. Performed drain diagnostic. Tested all drains in unit with no blockages. Cleaned shower drain and ran water down all drains including shower for 15 min with no back ups. The rooms resident said that this had happened a day or two ago but has not done it since. There could have been a blockage at that time that had released in the last day. Could not get shower drain to back up. Customer will call if problem reoccurs. We will need to video inspect line at that time.
