Determine the right pipe diameter for your plumbing project
South Carolina is in Climate Zone 3 - Warm-Humid/Warm-Dry (moderate heating and cooling). Homes here typically have higher cooling demands than heating.
Proper pipe sizing considers several factors:
Typically 3/4" for the main branch to the bathroom, with 1/2" lines to individual fixtures. If the run is long or you have low pressure, the main branch might need to be 1".
High pressure helps, but you still need adequate volume. A small pipe with high pressure delivers water fast but not much of it. Size for flow, not just pressure.
Most homes have 3/4" or 1" main supply lines from the meter. Branches to individual fixtures are typically 1/2". Older homes sometimes have undersized 1/2" mains.
Slightly. PEX has smooth interior and maintains flow well. Galvanized steel corrodes internally over time, reducing effective diameter. Copper is in between. For new installations, the differences are minor.
