People who have kitchen sink sprayers know just how handy they can be. Unfortunately, anyone who has had one malfunction also knows how frustrating they can be when they break. While replacing the sprayer is relatively easy, here are five steps that will make the entire process run more smoothly.

Step 1 - Before Replacing, Try Cleaning

The most common reason a sink sprayer fails to work is that it becomes clogged by mineral deposits left behind from the water running through it. Before replacing a sink sprayer try using a mild mineral deposit solvent on the sprayer. Dilute the solvent with some water and pour it into a glass or metal cup. Let the sprayer soak in this solution for a while so that the solvent has time to work its way into the tiny holes in the sprayer nozzle.

Step 2 - Turn Off the Water

If the sprayer cannot be fixed and must be replaced, turn off the water to the fixture before working on it. The water supply valve should be located directly below the sink. If the supply shut off isn’t right below the sink or simply can’t be found, shut off the water for the whole house.

Step 3 - Thread the Sprayer Hose Through the Top of the Sink First

This seems like an obvious step, but many eager homeowners go directly underneath the sink and connect the hose to the diverter line. Once accomplished, they realize that the nozzle head will not fit through the hole in the sink from the bottom up. Avoiding this silly mistake will save time.

Step 4 - Inspect the Diverter Hose for Build Up

Replacing a sink sprayer, at its most basic level, is as easy as disconnecting the old sprayer from the water supply diverter line and screwing the new one on. Once the old sprayer has been disconnected, one should inspect the diverter hose that the new sprayer hose will be attached to. Build-ups can clog these diverters and if one connects a new sprayer hose to a clogged line, the new sprayer will work as poorly as the old one. However, even if the old sprayer was working properly, it’s still a good idea to run a pipe cleaner through the diverter anyway to maintain maximum water flow efficiency.

Step 5 - Make Sure the Connections are Sealed Tight

The connection from the diverter to the sprayer hose should be very tight to prevent leaking. This is important because leaking underneath the sink could produce dangerous mold or cause water damage. In addition, the efficiency of the sprayer itself may be affected as the water pressure will be reduced by the leak. To make sure the seal is tight, use teflon tape on the threads before screwing on the sprayer hose. Test the new sprayer hose after it is installed and check for leaking. If a leak does exist, tighten the connection.
