Homeowners state that the kitchen sink drains are leaking and called us to come replace them with plastic tubular pipe. Upon arrival I was greeted by homeowner at garage door and she explained the situation and showed me the kitchen sink drains. I did my inspection and found that the expansion tank is blown and the t&p line is full of water and couldn’t locate the PRV but did find the main water shut off. I did offer to replace the t&p valve and expansion tank but due to the age of the GWH homeowner wants to wait. She agreed to the investment of new tubular pipe and I began by removing the old chrome pipe which came off in pieces and installed a new p trap and replaced the all the tubular pipe. Once it was all in and properly connected I ran the water and noticed the water comes up both drains some but still drains after shut off the water which homeowner states it’s normal. I suggested replacing the drain and the GWH but since she is retired and on a fix incoming she wants to wait and
