Here is a good rule of thumb for replacement versus repair. Yellow brass faucet the customer should be given a price to repair. It is not their fault that you do not have the knowledge or skill to identify the faucet and assume it is junk because you have never seen it before. This actually informs me that you just refuse to pick up a repair book or go on line to investigate and become an expert in your profession. Your pricing should include minor repair (stems and seats), complete repair (stems, seats, trim) and a new installation allowing the customer to choose what is in their best interest. Once you give all the information to the customer that allows them to make the best decision along with your input the customer should make the right choice.
Frequently your faucet repair parts companies will allow you to send them a text picture and they will identify it for you if that is your weak area and this can be discovered in less then 10 minutes.
When the existing faucet is red brass it means it is deteriorating and requires a replacement.
I am having a difficult time understanding why people are afraid to give all the right information and pricing to their customers. You may want to trust your customer more and if that is a problem learn to communicate with them better and express your ideas that engage the customer.
