Tested water getting 5 grains of hardness, 0 iron and ph value of 7. Customer stated kitchen faucet had low water pressure but all other fixtures in the house have good pressure. Performed diagnostic on water pressure. Customer had multi turn shutoff valves under kitchen sink. Removed supply line from faucet and tested water pressure getting good pressure through shutoff valve. Removed spray head on faucet and tested hose getting good pressure. Cleaned aerator on faucet head and re installed still not getting good pressure. Spray head has debri inside causing low water pressure. Customer decided to get faucet replaced. Turned water off to building and replaced hot and cold shutoff valves under kitchen sink. Removed old faucet and installed new kohler forte faucet. Customer is on a well and has no filter. Provided estimate to install filter to prevent debri from damaging fixtures and customer agreed to work. Installed new whole house filter in basement. Turned water back on to building
