Hello all, I do not have much plumbing experience but am following my father's footsteps of being a DIY'er. My sink faucets and shower have always been a bit off since moving in about 6 months ago and seem to be getting worse. They require the hot water to be on full go while originally needing the cold to be on about halfway to get nice warm/tepid water to come out. Over the last two months, we have had to keep dialing back the cold water to keep the temperature comfortable. In other words, with the hot water on full go and cold water on half go, the water is still tap cold. Our shower has one dial for hot and one for cold with a diverter in the middle. We have to turn the hot water one 4 times while the cold is only turned 1/2. What should I look at to fix this? Any help is appreciated as it was hard to put my issue into words to begin with!
