Residential Sink Faucet
When replacing the kitchen sink faucet it is important to note how many holes you have in your existing sink some sinks have one hole for the faucet others have three holes for the faucet sometimes you have a soap dispenser or a pull-out sprayer location. To replace a kitchen sink faucet you must first gather all of the necessary materials and tools to complete the task. First thing you will need to do just turn the water supply off to the faucet and drain the faucet by turning on the hot and cold until the water completely stops coming out of the faucet you do this to ensure that the water supply shut off valve underneath the sink does operate fully without leaking. Then you will lay the towel down or have a bowl available to catch the water that will come out of the shut-off valve water supply line connection when you take it apart. Then you will remove the mounting nuts best secure the faucet to the sink and remove the faucet. Then you will need to clean the sink surface where the old faucet may have left a residue you can use a rubbing compound or cleaning product that is recommended for your surface. Then install the gasket on the bottom flange of faucet with the tapered end pointing up then install your mounting hardware hand-tie and then adjust the straightness of the faucet from the top side of the sink and then tighten fully to fasten in place and then check 4 loosenesses by attempting to shake the faucet. After the faucet is securely mounted to the sink you then connect water lines to the faucet being sure the faucet connection does not turn by using a pair of channel locks or a sink wrench to hold it still while using another pair of channel locks or a sink wrench to tighten the water supply connection to approximately 30 lb of torque. once the supply line connections are connected to the faucet securely you would cut the excess water line off and connect the hotline of the faucet to the hot shutoff valve on the left side because hot is on the left and cold is on the right. Or that is how it is intended but is always good practice to ensure the hot and the cold or on the proper sides.
Once all your water connections are properly secured and tighten to approximately 30 pounds of torque on a compression style connection make sure the kitchen faucet is off and turn on the water supply on the shut-off valves underneath the kitchen sink one at a time and inspect visually for leaks it is also a good practice to take a Brown paper towel so you can visibly determine if there is water leaking at a minuet level not easily detected by visual inspection. Once the water lines and the faucet are pressurized and there are no leaks underneath the sink you will then remove the aerator on the spout and flush the faucet by turning it on at low pressure to spit and Purge the air out of the waterline and faucet this also make sure no debris is inside the faucet from manufacturing or install once you have good pressure and the valve has been purged of air reinstall the aerator clean up all your debris and check again visually and with a brown paper towel for leaks and you’re all done.
