Installed customer supplied lavy faucet. Tested no leaks. Added lubricant and changed a seat and spring to the cold side cartridge of a Morn lavy faucet as a courtesy. Customers kitchen faucet is very old. The retaining nut is too large for any of my tools to grab, not even my large bases wrench can fit. In the cabinet, there is a wall of plumbing blocking the back end of the cabinet, so I had to remove his garbage disposal to make room for my hands. I had no luck and he didn’t want me to cut it out. He let me know his main interest in having me come was to get the pullout faucet head back onto the supply line, but it’s lost it’s threads. I picked up a generic faucet head from Home Depot but unfortunately they didn’t have one in Black. I let him know I would try to find a BLANCO 441208 Torino Anthracite branded faucet head and call him about what it would cost to install. While I was testing the faucet the cold water supply anglestop broke, so I quoted him to fix it. Whi
