I want to replace and change location of my existing gas water heater from my attic to my garage. The gas supply I understand... easy! I have 3/4" copper from my wall to my WH. I would like to replace the copper with PVC or PEX because I will have to move about 50 ft... 1). Are there any problems I do not forsee moving the WH 50 ft? 2).Will a Watts recirculation device help get water faster? 3).PVC or PEX? 4). What is the best way to transition to PVC... and /or PEX. 5). Any other advice is welcome.

Where do you live, what state and city

(Rockwall) Dallas, Texas

I'd go with PEX and the Watts would be a good idea with this length of a run.
