After a inspecting the customers kitchen faucet, I was confident that he needed a new cartridge. Unfortunately it will need to be need to be ordered in because it is a special part. Will need to give customer a new quote once I get more information from supplier on the part cost. Also gave the customer the option to replace the kitchen faucet. Customer also wanted me to take a look at the guest bathroom toilet, it was determined that nothing seemed to be wrong with toilet. But I did recommend him that I could only replace his toilet because the tank is attached to the toilet and would not be able to replace the internal parts. Customer said he would discuss it with his wife and get back to us.
