Arrived on site client stated her tub would back up when using the kitchen. Upon inspection in the home I found that the client needs a minor rebuild on the toilet, the shower diverter doesn’t have an insert for the tub spout, the main shutoff valve is a sharkbite ball valve and she needs a new sink with new drainage underneath the sink. Gave options for all and client stated her biggest concern for today was to unclog the tub so she could use her kitchen sink and shower again. Today I unclogged the tub through the kitchen sink and replaced both hot and cold valves for the kitchen sink along with new faucet supplies and studor vent as courtesy. Turned water back on and tested for leaks. There are no leaks and the tub no longer backs up when using the kitchen sink.
