: I have just replace the entire hot water line and hot water heater in my 45 year old house. Replacing
: the line resolved all of my hot water pressure issues except one.

: The line runs from the water heater down underneath the floor and then splits. One side goes to my
: kitchen and then down to the main bathroom w/ shower and sink. Everything that way works fine. The
: other side runs back to an apartment on the back of my house which I rent out separately. The way the
: house is set up, this part of the line feeds a bathroom sink, then a shower and finally the apt. kitchen
: sink. The apt. kitchen sink is where the hot water pressure is non -existent. I have checked the faucet
: for clogs/etc but found nothing. Both the shower and bathroom sink work fine. Is this happening
: because the kitchen sink is at the end of

Long distance and small pipe size can restrict flow. I would consider the aerator on the faucet first though. Next I would check for flow at the shutoff under the sink for flow. Terry
