When someone is taking a shower, if someone else turns on the hot water in the kitchen sink, there is NO hot water in the shower. How can this be fixed? 7 May 2003 at 10:44 am #294406 Retired plbg1Participant If the water line is under sized then you have to put in a larger line to the fix, use only one at a time. 7 May 2003 at 1:41 pm #294407 racefanoneParticipant Install a pressure balanced shower valve,that will take care of the problem. 7 May 2003 at 10:32 pm #294408 mikeinpaParticipant You may also have galvinized piping that may have corrosion restricting flow ,may need to replacewater lines Author Posts Viewing 3 reply threads You must be logged in to reply to this topic.
