FAQs: Plumbing in Home Renovations

Do I need a permit to move plumbing in Los Angeles?

Yes, any major change to water supply, waste lines, or venting typically requires a plumbing permit in Los Angeles. Unpermitted work can result in failed inspections or fines during resale.

Can I keep existing pipes during a renovation?

If they’re in good condition and up to code, yes—but older homes with galvanized pipes should strongly consider an upgrade to copper or PEX to improve flow and reliability.

What’s the biggest mistake people make during a remodel?

Not involving a licensed plumber early. Plumbers can identify layout conflicts and suggest efficient solutions that save time and rework.

How long does plumbing take during a kitchen or bathroom remodel?

It varies, but rough-in work typically takes 1–3 days, with final installations adding another 1–2 days depending on fixture complexity.

Will my water be shut off during renovation?

Yes, temporarily. We always give advanced notice and aim to restore service same-day whenever possible.

Can I move a toilet or sink to a new location?

Yes, but it requires careful planning and often floor or wall modifications. Drain slope and venting are key considerations.

Should I upgrade my water heater during a remodel?

If it’s more than 10 years old or doesn’t meet your new needs, upgrading to a tankless or high-efficiency model makes financial and environmental sense.

Can I add a second bathroom or laundry room?

Yes, but first a plumber must evaluate whether your main line and venting can handle the additional fixtures without risking backups.

Are there rebates for plumbing upgrades in Los Angeles?

Absolutely. Zenon Plumbing helps homeowners access rebates through LADWP and SoCalGas for high-efficiency toilets, water heaters, and smart irrigation systems.

What’s included in a plumbing inspection for a remodel?

Inspectors check for correct pipe sizing, slope, venting, pressure tests, and backflow prevention. All work must be up to California Plumbing Code.
