Kitchen sprayers are handy for washing off the sink, vegetables, or even for washing your hair. Despite their usefulness they are not needed or used all of the time. The periods of disuse can lead to a buildup and low water pressure.
I notice many kitchen faucet sprayers have a tendency to clog up and not allow much water pressure through the head of the sprayer. Here is a quick tip to soak off that hard water build up and unclog the sprayer head. This quick fix can restore the water pressure and usefulness of your sink sprayer.
If for some reason a descaling doesn't work or if you have a leak in the sprayer hose itself, you may need to replace it. Instead of changing the whole faucet you could replace the sink sprayer. This is a little more involved but is still very easy to do yourself.
To help keep the sink sprayer in good working order, make a habit of using it on a regular basis. Just a quick spray can keep it from clogging up or drying out and causing a leak.
