My kitchen faucet only trickles until I press my sprayer. Pressing the sprayer USUALLY triggers the faucet to flow normally. Only occasionally will the faucet flow normally when I first turn it on. Could it be my diverter? If so can I fix it myself or do I need a plumber?

Please help

Yes, I'm almost positive it's the diverter - sounds like it's getting jammed. It probably needs to be cleaned out, or at worst replaced (dont worry, diverters are quite inexpensive).

You don't need to call a professional plumber - that's what this site is for. ;)

In order for us to give you the directions on how to do this, we need to know about your faucet, the more information the better. What brand is it? Is it single- or double-handle? etc.

Post back and we'll try to help you.

Good luck!
