So we are building a basement bathroom and my husband cut into the mainline and routed the plumbing to the new bathroom..all works great..no leaks..no problems. However, now we aren't getting hot water upstairs..the water is warm but not super hot like it was before. I turned the valve off to the new bathroom and the hot water resumed upstairs.. anyone have any ideas what we did wrong and how to fix the problem?!
rather than type it all again, read this thread and check it out against what you've done. if it doesn't apply to you, post a couple of pics of what you've done so we can have a look hot water tank cross lines? no hot water
