I have 2 showers. There were new faucets put in just before I moved in. The front shower does not get very hot at all but the back shower is too hot. Could this be as simple as the regulators. My house is up on cement pilars and you can walk upright under my house. Someone had suggested that the hot water was possibly running to the back shower and then to the front. I would prefer it being the regulators but I do not have an allen wrench that fits to get the handles off. They are both single handle faucets and I noticed that the front one only turns 1/4 turn but the indicator letters show 1/2 turn

What's the brand name of the shower valves? Do they have Posi-Temp or Skald-Guard features? Get a Allen head wrench, open up the valve and tell me. Regards, Tom

I do not have the right size allen wrench to get into it . I guess I need to get one. How do I know what size to ask for at the hardware store? The front shower is a Delta brand and it is a new model, Will I be able to tell when I do get it open which temp control it has and how to adjust it?
