I just purchased a new home, the water in the sinks get extremely hot while the water in the showers and tub barely get warm, I have turned the temperature all the way up on the hot water heater, what can be done to increase the temperature in the showers and tub?

Do NOT increase the temperature on the water heater. This will create an unsafe condition. The problem is not in the temperature but in the amount of flow of hot water to the bathroom. You mention showers (plural) and tub. If there are two bathrooms involved, the water restriction resides in the hot water supply pipe to these areas. If only one shower & bathtub are involved, the problem might in the bathtub & shower fixture itself. Please respond with more info. There are many plumbers online ready to help.

Can you tell us the brand and the model number of you faucets? Thanks.

Hey dezjones...

First, I would have you return the temperature of the water heater back to around 120-125 F.

Then I would have you remove the handle and trim from the tub/shower valve and then make an adjustment to the TEMPERATURE LIMITING DEVICE.

Once handle/trim is removed you should see something that has gradations (delta, grohe, Kohler, and price pfister valves) or you may see a simple screw (symmons valve). This will need to be adjusted to allow more hot water into the valve.

See what you find, and then if no luck pop back here with a name and model or a picture with the handle/trim Off the valve and we'll see what we can come up with.

Glad to help...
