temp change

[kefuss2]

what can cause my water temp to change instantly while taking a shower, no body else in the house turns on any water nowhere

Hot to cold or cold to hot?

And what type of shower valve? A single handle or 2 faucets?

hot to cold and then back to hot,, about evert 10 to 15 seconds it changes,, your takin a hot shower and cold water hits you all of a suden, then back to hot,,, it has a 2 handle faucet,

Bad point-of-use water heater?

While it could be quite a few things...

I am going to guess that you have a temp and or pressure shower valve that is not working right...that would be where I would start looking for a problem...unless you are having the problem else where in the home...
