shower water temperature fluctuation problem
 

hello, i'm having a problem with my water temperature when I shower. Whenever I turn the shower on, even at a low pressure, the water temperature will go from from hot to cold to hot without reason. it seems to be related to the water pressure b/c when it gets colder, the water pressure increases slightly even though I'm not turning the controls. the fluctuation gets worse if I turn the water on all the way so I can't use the shower at full blast.

Any ideas what needs to be done?

Thanks in advance for the help!

A bit more info would help . . .

Do you live in a house or a multiple unit place?
Do you have a temperature thermostat control on the shower ? (Post a pic)
Do you have an "instant hot" system or an "on demand" water heater?

thanks for the reply, callmevilla. i live in an apartment building. There is no temperature thermostat control. I don't know about the "instant hot" system or "on demand" water heater but I've never heard those terms being used.

What floor of the apt complex do you live on?

Could be a problem with the pressure balancing mechanism in the shower cartridge.
Call you rental office/landlord or maintenance crew and have them look at it for you.
That's the beauty of renting. ;)

KOK is right here . . . as a renter, you do not need to take on this issue. However, you might want to observe the fix because you will NOT be a renter all your life. Learn now -- benefit later!

Good luck if the building is more than twenty years old.

I'm not renting. I do own it. I attached some pictures. It's the 11th floor. The maintenance crew said they can't do anything. Building was built in 1983. Any idea what the work would entail, how long etc, and how much it would cost? Thanks in advance

You would have to put in a pressure balance shower unit, not bad if you can open the wall behind your tub.

thanks for the reply nealtw. I have tiles behind the shower/tub so i'll have to tear that down? How long do you think it would take to take care of it? Any idea of cost of parts?
