Need Help deciding pipe size
We have to run our main line 1400’ from the rural water supply line. They gave me a 1” meter and CTS lead. I’m going to use CTS for the rest of the run. But trying to decide between 1” and 1 1/4” pipe. We have 5 full bathrooms and will be doing 2 50 gallon water heaters. Leaning towards 1 1/4 but not sure if that would actually do anything
