Water pressure troubleshooting help needed
I installed a new water heater and now my water pressure seems to be down by about 1/3.
I also changed the 1/2" copper supply tubing to 3/4" and added a dielectric union where there had been none at the point where the copper in the house connects to the galvanized from the meter.
I didn't change all the supply from 1/2" to 3/4", just to through the new water heater, as shown in the drawing. I figured I'd get to the rest later.
The pressure is lower as soon as a faucet is turned on. There is no initial rush and then a pressure reduction, which I think would indicate that there's not an obstruction in the new pipe.
