The water in two Bathrooms will only get luke warm. Master bath gets hot so temp is set fine. Help!?

This is a new construction so hot water heater is new. 3 bathrooms are on one side of the house and share 1 water heater. Kitchen/laundry room share another water heater. Water will not get hot in the two hall baths - even after filling up the bathtub with only the hot water on - only gets a little warm. 2 hall baths are directly accross from the hot water heater. In master bath, water in the shower and bathtub gets hot quickly, but sinks take 2 minutes to get hot. Any suggestions? I'm ready to get my kids' toys out of my bathtub! Theirs is too cold to take a bath in!The water in two Bathrooms will only get luke warm. Master bath gets hot so temp is set fine. Help!?
Probably has nothing to do with the water heater.





Your tub/shower valves are most likely anti-scald units and their preset adjustments are turned down.





If you do not have the paperwork for your valves, determine the brand, go to the manufacturer's website %26amp; download the owner's manuals for them. The manual will have instructions on how to adjust the temperature setting.








Good luck...The water in two Bathrooms will only get luke warm. Master bath gets hot so temp is set fine. Help!?
In a lot of new tub and shower valves there are temperature control settings so that someone will not get scalded if they are showering and the toilet is flushed or anything else suddenly calls for a lot of cold water. It sounds like you have that kind of valves and they are set too low. If you can determine the brand and model of the control valves, you can probably look them up on line and find out if you can set them or if you wil need to cal the plumber that installed them. He maybe able to explain to you how to set them over the phone.
First check your hot -water heater settings..As code new construction uses a pressure balance system in showers and tubs. their is an adjustment cam behind the Faucet handle that controls the temperature and mix. This is used to prevent scalding but if maladjusted will give you water that is lukewarm or not hot enough
My guess is that the bathtub faucets have a temperature sensor to keep from scalding that is not properly set. Look up manufacture to learn how to adjust, or talk to home builder.
have the plumbing and faucets checked carefully. there may be a mistake in the hot/cold supply lines, or faulty bathroom fixtures.
