Pipe sizes are not what they sound like — the name is a nominal size, not the actual measurement. Knowing how to measure the diameter saves a trip back to the store with the wrong fitting.
The nominal size
A half-inch pipe is not half an inch across; the name refers to the pipe's nominal size, and the actual outside diameter is larger.
The measure
Measure the outside diameter with calipers or a tape, then match it to a pipe-size chart for the material.
The thread
Threaded fittings are measured by their nominal size, and the threads must match the pipe exactly.
The tip
For a quick match, take the old part to the store rather than trusting a guess. hard water is common across the region, and older neighborhoods still have galvanized supply lines In Monroe, a pro always matches the exact size.
The chart
Measure the outside diameter and match it to a chart for the material, because copper, PEX, and PVC all size differently. The nominal size is not the measured size.

Before you start
For Monroe homeowners, first identify whether the symptom is isolated to one fixture or appears across the home. Note when it happens, what fixtures were running, and whether the main shutoff is accessible. Photos and model numbers help a professional make a faster, more accurate recommendation.
A simple decision checklist
Before approving work in Union County, ask what caused the problem, which repair options were considered, what access or permit work is included, and how the finished work will be tested. Confirm the scope, materials, cleanup, warranty, and price in writing.
When to stop DIY work
Stop troubleshooting if water is near electricity, sewage is entering the home, a gas appliance is involved, a pipe may be frozen inside a wall, or the repair requires opening a structural surface. Shut off water when safe and call a qualified professional.
