Upon arrival customer informed me that the dual kitchen sink was leaking. Previously on 3/28 on replaced a basket strainer and the piping to the dual sink. Customer wanted to be as cost efficient as possible so he ended up replacing only one strainer. Owner relayed to me that he didn’t even know it was a double sink. I replaced strainer with Wolverine brass. Drop tested for leaks. No leaks. Customer has John the plumber bill his company. Will late office handle payment
