No cold water, hot only

Originally posted by Mstewart Quick update, Now we have hot and cold water in the bathroom, nothing at the indoor kitchen sink, and hot only at the outdoor/garage sink. I have no idea....

Indoor kitchen sink most likely has a plugged screen at the outlet.  Unscrew and clean the screen.  As for the mystery of only hot water at the garage sink - the only thing that makes sense to me is that the line is pinched somewhere between the pump and the outlet at the garage.  If you aren't the original owner maybe the previous individual stubbed it off?  Follow that line from the outlet to the pump, you will certainly find the problem there.  By now you must have temps above freezing so I doubt you still have ice in your pex line.  Also, when the pump is on does it run for a bit and then shut off or does it continue to run.  If it continues to run you either have a pump issue or a leak in the pex.  If pex is leaking you should easily be able to spot water running on the floor or in the stow areas or leaking on the ground underneath. 

Keep us posted and let us know what you have done up to this point.
