I have moved my hot water tank to a new location in the basement. The new location is closer to the main water line. The best way for me to describe it is; from the street to my house to the water meter and from the water meter I have 7ft. Of 3/4" pipe. I want to run a 1/2" pipe to my hot water tank first. And than to the rest of the house. So this is possible and the right thing to do.

Thanks,

Water heater should have at least 3/4" incoming cold water line. Also, outgoing hot water has to be at least 3/4" inch.

The output of he hot water heater needs to be near the point of use to minimize energy consumption. Ours used to go under the basement to get to the most used stuff.


3/4 in. 3/4 out at least most of the way. Fixture drops should be 1/2, but the trunk should be 3/4.

All good advice here. The shorter you make the hot pipe coming from the heater to more efficient it will be due to heat loss as the water runs down the pipe and warms it. Shorter runs are best.
