Water leaking down sprayer hose under sink. American Standard Jasmine high flow 3821.831 or 834.

Maybe just loose or needs a O ring.

sounds like its either just not tightened enough or you need to buy a rubber washer to put in it. Right at the bottom of the sprayer.

I had the same issue with an American Standard faucet that I installed new 6 months ago. The diverter can be the issue if you have a sprayer attachment. Try unscrewing the sprayer head from the hose it's attached to. Now run the water full pressure with the hose pointed into the sink, obviously :~). After running the water for about 1 minute, connect the sprayer head back onto the hose, make certain the flat rubber washer and ring gaskets are seated in their grooves properly, and tighten until you have no water leaking from the sprayer head/hose connection. Now try the water through the faucet. If the problem was a temporary diverter issue, your pressure should be fine now. Good luck

How long have you had this? is everythign tight? check underneath the sink to ensure all connections are tight. The spout may have came loose, and it may not be able to be fixed, may need to be replaced.

Using the number you gave it is an American Standard faucet here is a link to a parts place.
I would use the factory parts.

hello, you may have a air pocket in the line try shutting of the water supply and then sqeeze the handle and slowly turn the water supply back on with the hose handle squeezed on till the air is forced out, hope this helps

Faucets are fastened with nut(s) under the sink.
-Turn off and disconnect the water supply hose from the faucet.
-If this is a faucet with a sprayer you will need to disconnect the sprayer hose from the faucet as well.
-If this is a bathroom sink you will have to disconnect the drain stopper assembly, this should be self-explain when you look at it.
-Remove the nuts or nut holding the faucet in place. This can be a difficult task to get a wrech or pliers on the nut(s). If you are having difficulty you may need to acquire a tool called a "basin wrench" most hardware stores carry them ask for it, if the person knows his department he will take you right to it. They arn't terribly exspensive.

you need to replace the 0-rings in side the spout between the base and neck,

Start by removing the spray head from the hose. Pull the spray head out and with a channel lock pliers unthread connection between the spray head and hose. BE CAREFUL not to let the hose fall back down into the faucet. With the hose directed down toward the sink test for volume by turning on the faucet. If you get a nice volume the problem is in the spray head. This is usually the case. Put the spray head back on then remove the aerator. It's the screen where the water comes out of the spray head. Clean out the assembly ( 3-4 parts). Reassemble and test.

Good luck, Phil
