My shower is freezing cold: what can I do to fix it?

Question: my shower is freezing cold. The sinks get some good, high temps, but I can’t figure out how to get warm water in the shower. And the faceplate for the knob in the shower doesn’t come off, so I can’t find a scald guard. Alas, that isn’t really a tool question. But if there’s something you want me to focus on, let me know.

Unless the supply line for the hot water pipe feeding the shower is shut off (or nearly off) this sounds like a plumber job. If you can find the pipes that feed the shower, check the valves (they usually look like garden hose valves). If you can open them (lefty-loosie is what you’re looking for; or in-line with the pipe if its a handle) you might get more hot h20 supplying the shower. Otherwise, you may have a water blockage (I imagine Arizona has loads of minerals in the water which corrodes and blocks pipes) and may need a plumber to locate it, cut it out and so on.

You’ll also need to brush up on your drywall skills because the likelihood he’ll have to open up a wall or walls sounds high. Look for pipes coming out of the hot water heater and under the bathroom sink and/or in a closet in the bathroom. Valves may also hidden in little cubbies behind little doors in the backs of closets. I’ve also seen them hidden behind “magazine racks” and other carpentry elements that cover a hole from a previous repair on the shower-supply wall.
