Plumbing & Bathroom

Every US home should have an accessible main shut-off valve, and most fixtures have their own isolation valves that should be tested periodically so they are not frozen shut when you actually need them. Pipe material (copper, PEX or galvanized) changes which cutter or fitting tool is actually the right one.

Pipe-size compatibility and pressure ratings are checked against manufacturer documentation before a plumbing tool is recommended for a specific pipe material or repair task.
