Hi Rody Ryon, Thank you for your question!
Too correct your hot and cold reversal issue, please follow the steps below:
First shut off the water supply to the faucet.
Remove the sleeve, bonnet ring and cartridge. Pull the top cap from the front of the cartridge and rotate it 180 degrees or one half turn. Reinstall the cap back onto the cartridge.
Reinstall the cartridge making sure that the key is fully engaged with the slot in the brass body.
Reinstall the bonnet and sleeve and also make sure that the O-Ring is behind the groove on the brass valve body.
Reinstall the handle assembly and temperature dial. When you now turn the temperature dial counter clockwise, the temperature of the water should get hotter.
Best regards, Brandis
