Use and Care Manual
What should I do if my two-handle kitchen or lavatory faucet drips 
from the spout?
For Two-Handle Faucets, First:
•  Check  under the sink to determine what type of valve is installed.
•  Look for the supply tubes coming out from under your faucet. If they are 
flexible gray tubes, you have a model with a DIAMOND
™
 Valve. If you don’t 
have gray PEX supply tubes, you most likely have a two-handle valve with  
seats and springs.
For DIAMOND Valve Models:
•  Refer  to the Installation Instructions/Owner’s Manual (available on 
deltafaucet.com) for your specific model to ensure the handles are 
properly installed. If they are not correctly installed, the valves may 
not completely close, causing the spout to drip.
•  Reinstall  handles if necessary.
•  Contact  1-800-345-DELTA  (3358) or visit deltafaucet.com/customersupport 
for assistance if you continue to experience issues.
For Non-DIAMOND Valve Models:
•  Follow the Early Maintenance instructions on page 3 of this guide.
•  Replace the seats and springs (see illustration below) if the faucet continues to 
drip. To obtain replacement seats and springs, call 1-800-345-DELTA (3358) 
or visit a local Delta
®
 Genuine Parts dealer. 
•  Visit  deltafaucet.com/customersupport and choose the appropriate link 
or use the search tool for complete instructions on how to replace your 
faucet’s seats and springs.
