So I want to upgrade the plumbing in my house/rental unit. I'd like to replace much of the old galvanized stuff with copper. The problem is this...the supply line coming into the house is 1/2" copper. It runs through the water meter and then into 1/2" galvanized. Obviously this isn't ideal. Not much I can do about the supply line, however, I'd like to run 3/4" for the mains through the house and then 1/2" coppy lines to each individual unit. Question is this.....what will happen if the supply line is 1/2" and I run the mains through the house with 3/4". Will the pressure be high when the water is turned on at the faucet and then immediately drop as the 3/4" pipe is emptied and slowly filled with the 1/2" supply?
No announcement yet.
1/2" supply line from road, what to do inside?
