Plumbing in the Home/Faucet pressure
We have an odd situation with a delta custom kitchen faucet. It is a standard two lever faucet with separate sprayer. Recently the pressure all but disappeared in the main faucet however pressure through teHe sprayer is fine and even more bizarre when you engage the sprayer the faucet pressure picks up as well. Any ideas?
Try removing the aerator at the end of the spout and inspect it for any debris that may be blocking it. If its clear there is a piece in the faucet the switches off the flow to the spout when you engage the sprayer. Look in your user manual to locate the part, order and replace this.
