My contractor just did this. He says the 3/4 pipe will enable us to store more hot water in pipes. Pipe coming into house from main is only 1/2. Any thoughts??
happy rooster is right no matter how much water is retained in the house pipes you are still only going to get water allowed through 1/2 inch pipe it's only common sense
Increasing to 3/4 pipe is the right thing to do . By code they have to be 3/4.
your water pressure will go down. larger pipe to smaller pipe,pressure goes up. smaller pipe to larger pipe, pressure goes down. plus 3/4 pipe cost more.
