I have a delta single handle faucet and lately the spray does not have any water when I press it. I've replace with a new spray and still no water. I've also replace the diverter and no water seems to come out. Are there any other suggestion I could take to cure the spray problem. Thanks and appreciated

Are there any other suggestion I could take to cure the spray problem.
Yes. Shut the water off and open up the valve. Remove the seats and springs and the diverter. Now place a pan over the open valve body and turn the water back on for a minute to flush out the supplies and valve nbody. Before you button up check for trash in the valve. Good luck Tom
