Plumbing in the Home/delta kitchen faucet side sprayer


Hello, I have a Delta single handle kitchen faucet with the black side sprayer, both around 18 years old. I've hardly used the sprayer at all over the years and just recently tried it and it won't work. I've taken the nozzle portion off and tried it at a neighbor's house and it works fine there, so the nozzle isn't clogged.

Could the problem be in the hose? When I turn the faucet on without the nozzle attached, there's a stream of water coming out of the hose but not much pressure behind it.

Thanks for your help.


I would say you have answered your own question. The problem has to be within the valve or the hose assuming that the regular spout is producing a good flow of water. You can remove the handle and ball and if you have an air hose available blow out the port that the hose connects to and observe if you get some foreign material out of it or if you get a good unrestricted flow of air. You can probably tell if there is a restriction by merely blowing backwards through the hose also...of course you have to turn the hot and cold water supply off before removing the cap and ball.

I am getting far to many questions that do not give enough detail to warrant a good solution. I realize it is a little difficult to formulate a good question but if you want a good answer you have to give me good this entire introduction please....remember this website is world wide I have no clue where you live if you don't tell give more detail on the fixture you are having problems with...a one piece eljer 3.5 gallon flush will be totally different than a one-gallon flush toto.....details are important. I can answer most questions related to residential and commercial plumbing for many buildings. I have sufficient knowledge of the UPC and UMC. I will speculate for you if necessary. In those cases I will try to give you some guidance and you should use that to refine the question further and we, together, can seek the answer via a follow up.

REMEMBER, If you want a good answer you need to ask a detailed question and include where you live, type of pipes, type of building, water pressure if it is a water problem, type of heater, age of appliance & building all these and many more are variables that have an effect on various situations.
