Installing a New Faucet on Your Mop Sink
Mop sinks are built to withstand the test of time, but unfortunately, the faucets do not always hold up as well as the sinks. Luckily, replacing the faucet on your mop sink is a relatively simple DIY project that requires few tools and no prior plumbing experience. If the faucet on your sink is no longer doing the job, follow these simple steps to install a new faucet and restore functionality to your mop sink.
Step 1 - Turn Off the Water
Find the water connections for your mop sink, and turn off the water valve for both the hot and cold water. Turn on the faucet to make certain that there is no longer water flowing to the sink—if the water supply is not completely shut off, it could lead to a watery mess.
Step 2 - Remove the Old Faucet
Once the water has been shut off, you're ready to remove the old faucet. Find the connection between the water source and the faucet itself. Use the plumber's wrench to loosen and unscrew the fixture. Remove the nuts that attach the faucet to the sink, and place all parts in a plastic bag to take with you to the hardware store.
Step 3 - Purchase a New Faucet
Take the old fixture with you to the hardware store. Purchase a fixture that matches the connection size of the old one. The faucet itself can be of a new style, so long as the connections will work with the existing plumbing. Make sure that the faucet either comes with the necessary nuts and bolts to attach it to the mop sink, or that you purchase them separately at the same time as the faucet, as they will be needed to complete the installation process.
Step 4 - Install the New Faucet
Remove the new faucet from its packaging and review the included instructions, setting aside any bolts and nuts that will be needed. Wrap the threading on the pipes with Teflon tape to ensure a watertight connection. Place the new faucet against the pipes, and screw in any necessary connections. Use the plumber's wrench to screw on and tighten the bolts and nuts that securely fasten the faucet to the sink. If the mounting is not flush with the sink, use caulk to seal the faucet. Take a caulk gun with a caulk cartridge inserted, and create a thin bead around the faucet fixture. Smooth it gently and evenly with a finger or caulk tool.
Step 5 - Restore Water
Turn the hot and cold water back on at the connecting valves. Let the water run for several minutes to check for leaks. If leaks are present, remove the fixture and apply additional Teflon tape to the connecting threads. Once the faucet is completely leak free and securely fastened to the mop sink, the project is complete.
