A washerless faucet generally has a longer life than the traditional compression faucet. Although the latter is more preferred by consumers nowadays, it also tends to leak after long use. A washerless faucet is designed with either a single lever or with two handles. This type of faucet can be installed easily by a homeowner without having to hire a professional plumber. Here’s how to install a washerless faucet.

Step 1 – Shut Down Water Supply

Shut down the water source in the kitchen faucet. This can be done by shutting off the shut-off valves located below the sink. If there are no shut-off valves, shut off the main water supply.

Step 2 – Apply Plumber’s Putty on the Putty Plate

Remove the washerless faucet from its packing. On the faucet’s putty plate grooves, apply a sufficient amount of plumber’s putty. When working with an old sink, use a putty knife to remove any left-over putty.

Step 3 – Position the Putty Plate and Deck Plate

Place the putty plate and deck plate on top of the pre-cut holes on the sink. There are usually three holes on the sink designed for universal faucet installation. Make sure that the center hole of the sink is aligned to the hole on the deck plate. Press the two plates firmly in place.

Step 4 – Insert the Faucet into the Sink and Deck Plate Holes

Insert the faucet into the deck plate hole and into the precut middle hole on the sink. Work under the sink to secure the faucet with the mounting devices provided by the manufacturer. Refer to the faucet manual for instructions. Make use of the necessary tools for this job. Secure the lift rod, the stopper and the lever by following the precise instructions provided by the manufacturer. 

Step 5 – Make Necessary Connections

Connect all necessary connections on the faucet. Use an adjustable wrench to tighten all fittings and nuts. Use a basin wrench and adjustable pliers if necessary. Apply Teflon tape on fitting threads to ensure that no leaks occur. Make sure to wrap a sufficient amount of Teflon tape on the threads and never over tighten.

Step 6 – Remove Excess Putty

Excess putty may ooze out of the deck plate as a result of tightening the nuts from underneath the sink. Make use of a wet sponge or tack cloth to remove the excess putty.

Step 7 – Connect the Faucet to the Supply Line

Make sure to apply Teflon tape on the threads of the supply lines and connect them to the water supply pipes. Be careful when tightening the connection. Do not squeeze too much to avoid causing damage.

Step 8 – Turn the Water Back On

Turn the water back on to test if the washerless faucet installation is successful. Make sure that all connections are secure and no leaks occur.
