Thank you for your question, DAVE! Model B112900C is a WaterSense® Labeled product but should produce approximately 1.75 gpm @ 80 psi. If you are not getting this flow rate, we recommend removing the shower head to check for debris accumulation as well as flushing the valve body. The rotational limit stop will limit how far the handle will move to the hot mixing position. By turning the stop counterclockwise, you will add more hot water to the mix. Please feel free to contact us directly for further assistance.
Best regards, Edward
