Pride Plumbing came out and installed a customer-supplied widespread faucet on an employee handwashing sink. First, we removed the old faucet and cleaned the sink. Next, we installed the new widespread faucet along with new hot and cold braided stainless-steel water supply lines and tested for leaks and proper operation. That's when we found a blockage in the mixing valve. So, we removed it and then retested the faucet for proper pressure and operation with no further issues.
