Kitchen Sink Sprayer Troubleshooting

By Edited Sep 30, 2016 2 2

Many homeowners choose a kitchen sink with a much used option -- a sprayer. A kitchen sink-sprayer is very convenient when it comes to washing dishes, dogs or anything else. It is very frustrating when the sink-sprayer suddenly and without warning stops working. Sometimes absolutely nothing happens when you squeeze the sprayer handle or sometimes the water barely dribbles out. Sometimes you turn your faucet on and get sprayed with water from the sprayer, even though that may be a funny April Fool's Day joke, it's not funny any other day. Whatever the problem is, it is very frustrating. A kitchen sink-sprayer is not a high tech device, it is a simple design which makes troubleshooting a breeze. These are the most common issues and how to fix them when it comes to kitchen sink-sprayers. Begin with the easiest repair option and work your way to the more difficult one. Fortunately repair options or even replacement sink-sprayers are reasonably priced making this an inexpensive do it yourself project.

Check the sink-sprayer Hose

Open the cabinet doors that are located directly under the sink.

Locate the sink spray hose, which is usually located deep inside the cabinet near the wall.

Check the sprayer hose for kinks, twists, cuts, splits or see if something heavy is laying on top of it.

Straighten out kinks and twists or remove the heavy item taht is blocking the flow of water.

Replace a cut, split or otherwise damaged hose.

Take the old hose with you to a home improvement store or plumbing supply house to match the hose correctly.


To Replace a Kitchen sink-sprayer Hose

Purchase a new sink-sprayer hose kit at a hardware store, home improvement store or a plumbing supply store.

Remove the hex nut at each end of the sprayer hose.

Remove the old hose and replace it with the new one.

Tighten the hex nuts.

Check the Spray Head

Unscrew the sprayer head.

Fill a bowl with undiluted white vinegar.

Place the spray head into the bowl.

Soak the sprayer head in white vinegar for an hour or so.

Poke the holes out with a wire or strong toothpick being careful not to break the toothpick off in the hole. The sink-sprayer holes are susceptible to clogs due to  lime scale or mineral buildup.

Rinse the spray head thoroughly with plain water and twist it back on.

Check the Diverter Valve

Remove the spout on the faucet.

Locate the diverter valve directly under the spout.

Clean the diverter valve if there is any dirt and/or lime scale buildup or mineral buildup by soaking it in white vinegar for an hour. Rinse the diverter in plain water.

If you choose to, it is actually just as easy to buy a new diverter valve and replace the old one. Diverter valves are not expensive. If the old diverter valve is damaged in any way, replacing it is best.

Bring your old diverter valve to the store so you can match a new one exactly to the old one.

That is basically all that can go wrong with a kitchen sink-sprayer. There isn't much to the design of sink-sprayers.

Troubleshooting and repairing is quite easy and should not take more than a few minutes. Any skill level of do it yourself type homeowner can troubleshoot a sink-sprayer.

Really helpful sink sprayer info. Think I'll use the white vinegar cleaning tip right off. Good to know it's all simple to fix. I rely on it several times a day.
