I am having issues with temperature not getting hot enough and pressure not nearly where it should be. I have replaced the mixer valve (GP800881) and still the issue remains. I have now ordered the Rite-Temp®Test cap for K-8300 series valve bodies (https://www.us.kohler.com/us/univer...alves/1110259.htm?brandId=empty&skuId=1110215). Once I have this part, will I be able to test the pressure of both the hot and cold water supplies independently of one another? And what tool/device will I need to test the pressure?
