Hi, just bought a sink spray head, put it on and water is coming out the base of sprayer, what did I do wrong?

Hi! Yes it sounds like the spray diverter needs replacing. Kohler .com will have this part online or you could try a plumbing supply shop.

Someone else had this fix and it worked for me: (yay!)
*Remove water tank and collapse the hanger bar.
*Remove two screws at base of hose and work the hose off. It will come out.
*Unplug unit and hold over your kitchen sink with the hose inlet pointing into the sink.
* use your kitchen sink sprayer to forcefully spray water into this hole and it will come back out again releasing the gunk that has been stopping up the unit.
* for good measure, I also used the sink sprayer to flush out the hose.
Put everything back together. And make sure it is dry before you plug it in.
VOILA!!! WORKS GOOD AS NEW. HAPPINESS!

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.

Hi seawitch678,

If you have a granite or stone countertop/sink, use silicone as plumber's putty will stain the stone. Plumber's putty is petroleum based so it will not adhere to stone. Normally you should use what the manufacturer recommends and where they recommend. When installing a faucet, put either around the base of any piece that goes through the countertop.

Hope this helps. If it does, I'd appreciate your vote. Thanks,

If teflon tape was used, most likely the base casting split as overtighting can occur.

You need to turn the water off under the sink. Disconnect the sprayer hose from the threaded shank under the center of the faucet body. Pull the spray head out of the faucet. Contact Blanco to receive your faucet parts free.

With your faucet in the off position pull the sprayer out. Unscrew the hose that connects to the sprayer. This lets you take the sprayer to someplace where you can sit down. The front of the sprayer where the water comes out unscrews as well. You may need to use a nonslip mat or a piece of rubber but you can undo this by hand. Once you have this off a small piece (airator) can come out that helps control water flow into a steady stream instead of the way water comes out of a garden hose with no nozzle. form here you'll be able to see how the old button fits into the sprayer, pop it out and replace with the new one. Assemble in reverse.

Call Moen. Bad spray head or diverter.

check the sprayer handle by disconnecting and blowing into it and pressing sprayer handle and/or for possible kink at main body or hose by disconnected sprayer point hose into sink and turn on water. If no water the the diverter in main body is not working properly and needs to be reassembled or replaced

NO GLUE!!!!!!!!!  It is a threaded connection that secures it in place. It is a $5 part at Lowes or HD.
10 minutes to replace.
