Arrived on site client stated they could not install their kitchen faucet. Kitchen sink and drainage was already hooked up when we arrived. Hooked up kitchen faucet and turned on valves underneath to test for leaks. Tightened all tubular nuts for the drainage as they were not tight when we arrived. Their are no leaks at this time. Customer husband hooked everything up himself said he wanted us to double check everything from the faucet to the tubular we checked everything for leaks under sink didn’t find anything
