How can I adjust the anti scald feature on my tuscany siena faucet set. It is set far too cold, Thanks?
Remove the handle by loosening the set screw. Look around the handle for a small hole. That is where the set screw is located. You will need an alan key for this. Once removed you will see a plastic scungin with notches. Pull this out and rotate counter clockwise. This will allow the faucet to open more giving you more hot water. Then put it back together and enjoy a hot bath
