How do I fix a kitchen faucet with a diverter sprayer?

I have what I think is called an HM kitchen faucet with a top button that triggers a spray on the faucet handle. For a while it wouldn't pop back after pushing down to spray. I tried soaking it to release any lime but that didn't help. Neither did WD 40 or Liquid Wrench. I figured out how to push the button up from underneath and then pull it up by taking the button cover off and pulling on the pin inside. Still won't release on its own and is now starting to leak from that diverter button. Any way I can get in there to actually fix it?

Ebrud730:
There is a hex-nut configuration at back of the handle of your sprayer where the hose enters the back of the sprayer handle. You can use a wrench to unthread the back cap and hose and remove them. You will have full access to all of the goodies inside of the sprayer handle at that point. pull the parts out and clean them with a rag that has some tooth to it (such as terry-cloth) and wipe off the WD-40 and liquid wrench (they will adversely affect your "O-rings") clean off the o rings and plunger and re-assemble the sprayer. You may have to go to Home Depot or Lowes to get replacement "O-rings" to stop the leakage.

SOURCE: delta kitchen faucet mixed spray...diverter problem???

No a pull out sprayer problem is different.

First try this. Pull out the sprayer and remove from hose by turning nut that connects sprayer to hose. If you can get someone to help you it would be nice since the hose can go down into the faucet and might be trouble to retrieve. Look in the connection on the sprayer where the hose connects and look at the screen. If the screen is plugged or dirty clean and reinsert. If you can't clean it replace it. If this isn't working go to the next suggestion below.

In the spray head of the faucet there is a build up of deposits from use and or water hardness. Here is the link to the Delta site.

Delta Faucets

If you find you faucet model order a new spray head. Once these go bad they usually need replacing.

http://www.pricepfister.com/www/ImageAssets/mirror/model/kitchen/marielle/mar026-4n/26548-0500.pdf

Page 2 on this web site has the diverter listed. Sounds like the diverter is sticking or hanging up and not working right. The link below has information on the faucet you have so I hope this will be helpful for you.
First you could take it off and clean it and check it out for any blockage.

Kohler a112.18.1 diverter will not spray

Generally the sprayer trigger assembly will unscrew from the hose. You can then point the hose toward the sink and turn on the
water. It should flow freely through the hose when either the hot or cold is on. Generally there is a aerator on the spray head. You can access it by unscrewing the tip of the sprayer assembly and clean out any mineral deposits. There may also be an inline type filter in the handle where it screws onto the hose that can be removed and cleaned. If this doesn't help I would guess the on-off triggering assembly is broken and you would have to replace the sprayer head.Hope this helps.

Moen kitchen sink faucet side sprayer is stuck on

We had this same problem. We twisted off the sprayer cap to access the diverter valve under the trigger. The nylon diverter was stuck down into the cavity and was not popping out when the trigger was released. We pushed it down several times with needle nosed pliers to release it then applied a drop of household oil lubricant with the valve pushed all the way in. Then pushed and released several times to work the lubricant around the sides of the valve. After re-assembly, the sprayer seems to work perfectly again.

Sprayer leaking from inside handle mechanism

although it is possible that the spray head has gone bad, it is more likely that the diverter mechanism inside the kitchen faucet needs replaced. When this part is defective, it allows full pressure from the faucet to go to sprayer head even though the sprayer is not triggered. The sprayer is not designed to handle full pressure when it is not spraying.
