For this customer, he had a price Fister faucet for his kitchen sink and I recommended to try to repair the cartridges, for the cartridges to stop dripping however there is a part of the cartridge that would not come loose, indicating that we would have to replace the faucet. The faucet was from 2007 and we went back with the same style a faucet with that mind went back with the Delta faucet and with Delta faucet came with a sprayer so that is exactly what we installed. I had to replace the hot supply line because we weren’t getting flow to the hot water line and as a result of that the O-ring for the service stop valve had corroded on the inside, causing a clog so we had to disassemble the new faucet in order to get flow restored on the hot side only because it got trapped inside. I used the shop vac to clear the debris once complete. The flow is back to normal little bit of brown water for some reason and the customer is all set. I think the BROWN water was because of the shop back,
