I have a glacier bay kitche faucet and no water comes out of the spicket when hot or cold is turned on, it only comes out of the sprayer. I have taken the faucet off but do not know if there is a replacement cartridge and how do I get it out... or maybe I just need to clean it of debris? I understand home depot used to carry these faucets are parts still available??

There is a diverter in the faucet head the rerouts the water to the sprayer whne you pull the trigger. It is replacible and HD may carry parts but I doubt it. If you feel skilled disassembile it and see if you can remove any debris. If you aren't skilled just swap it out or return it to HD if its under a year.

Did you check the aerator on the end of the spout?
