Day 1: Customer called about air coming from their kitchen faucet when in use. Also mentioned low water pressure. Upon arrival inspected. Meter does not show leak. We installed the faucet 6 years ago. Provided pricing to replace the cartridge in an attempt to solve the issue, customer accepted. Found water in undersink cabinet. Small leak coming from spray hose. Showed customer the leak. Explained that we do not have the spray hose and that it would need to be ordered. Provided pricing for a spray hose replacement as well as new faucets. Customer agreed to pricing for a spray hose replacement. Parts on order, will return to replace. Day 2: Arrived on site to perform work as proposed. Removed existing spray hose. Installed new OEM spray hose provided by Kohler. Tested application, working as intended, no leaks detected. Installed weight. Faucet now working properly and pressure has improved. Thank you for choosing CPI!
