Can I Do My Own Plumbing Repipe Legally?

Sometimes — the homeowner's repipe (the PEX — the permitted) is allowed in many jurisdictions (the permit's — the required; the inspection's — the pressure's); the gas (the licensed's — the common) and the sewer (the licensed's — the often) are the professional's. The permit: the repipe's — the always; the DIY: the water's — the sometimes. The inspection's — the pressure test.

The water's DIY

The PEX (the homeowner's — the permitted's often; the manifolds'), the permit (the plumbing's — the required; the pulled), the inspection (the pressure's — the tested; the rough's), the materials (the listed — the PEX's; the fittings'), and the code (the IPC/UPC's — the followed).

The professional's

The gas (the licensed's — the jurisdictions'; the tested), the sewer (the licensed's — the often; the tap's — the city's), the water service (the meter's — the city's; the backflow's), and the multi-family (the licensed's — the commercial's).

Cost and process

The $4,000-$10,000+ (the whole-house — the PEX's; the 2-bath's), the $150-$400 (the permit's), the drywall (the repair's — the DIY's often), and the time (the 2-4 days — the professional's; the week's — the DIY's). The repipe's — the permitted; the pressure's — the proven.

The bottom line

Homeowner PEX repipes are allowed with permits in many jurisdictions (pressure-test inspection required); gas and sewer work needs licensed pros — budget $4,000-$10,000+ whole-house.
