In Lakewood, CA, more and more homeowners are making smart use of their backyards, building ADUs for aging parents, grown kids, or extra rental income. But while the idea might sound simple, the plumbing? Not so much.
That’s where Benjamin Franklin Plumbing of Long Beach comes in. We specialize in ADU plumbing services in Lakewood, handling everything from new water and sewer line connections to fixture installation and city inspections. Whether you’re converting a garage, building from scratch, or adding a backyard cottage, we’ll help you get it done right, on code, on time, and without cutting corners.
Plumbing for an ADU isn’t like adding a second bathroom. It’s more like building a mini home from the ground up.

Here’s what we handle:
We work closely with general contractors, designers, and homeowners alike to make sure everything flows the way it should, on the blueprint and in real life.
When you’re adding an ADU in Lakewood, cutting corners can be risky, costing you time, money, and your final inspection approval. That’s why every job we take on is built around code compliance from the start.
We stay up to date on Lakewood’s local ordinances, Los Angeles County regulations, and all California plumbing code requirements, so your project moves forward without unnecessary delays or red tape.
What you can count on:
No shortcuts. No surprises. Just plumbing you and your inspector can trust.

Whether you’re adding an ADU to a classic mid-century home or expanding a newer property near Del Amo, we understand the plumbing systems that run beneath it all.
At Benjamin Franklin Plumbing of Long Beach, we’ve helped Lakewood homeowners plan, build, and upgrade their plumbing with confidence. We know the local codes, the soil conditions, and the quirks of older infrastructure, and that gives our clients an edge.

Scheduling service was easy and the discussion of the work I needed performed occurred at my house and options were discussed. Once we decided on the items to be replaced and the work to be performed, I received the cost estimate and we scheduled a date for the work. Davy showed up on-time to perform the work and was very thorough in getting the job finished. The work was accomplished in the time allotted and Davy provided a detailed review of the work. Highly recommend contacting Erin and his team at Benjamin Franklin Plumbing to get top quality, reliable work at a fair price!

We had a plumbing emergency on a Friday night. I called the number and was able to reach staff there within just a few minutes. We scheduled to have Christian show up at 9:30am on Saturday morning. He arrived right on time. He completed the work and managed to come up with a great solution for a pretty complex problem. Fantastic job and very reasonable pricing. I will definitely be using them in the future if I need any plumbing work done!

To keep your water heater running smoothly in Lakewood, it’s a good idea to flush the tank once a year to clear out sediment, especially if your area has hard water. Check the pressure relief valve, inspect for rust or leaks, and make sure the thermostat is set to a safe temperature (usually around 120°F). Regular maintenance helps extend the life of your unit and keeps your hot water flowing efficiently. For peace of mind, consider scheduling a professional inspection with a local plumber.
If your water pressure suddenly drops or only affects certain fixtures in your Lakewood home, it could be a sign of a clogged pipe, leak, or a problem with your water supply. Try cleaning faucet aerators first, but if the issue persists, it’s best to call a licensed plumber in Lakewood to diagnose and fix the problem before it gets worse.
We are available 24/7 to take your call for emergencies. Our appointment hours are listed above.
For most homes in Lakewood, scheduling professional drain cleaning once a year helps prevent clogs, odors, and costly backups. If your property has older pipes, large trees nearby, or frequent slow drains, you may need service more often. Regular maintenance keeps your plumbing flowing smoothly and protects your home from unexpected issues.
We work built relationships with several lenders to ensure our customers are able to restore functionality in their homes. Ask your technician about your financing options.
Yes! Upgrading to low-flow toilets, water-saving showerheads, and high-efficiency faucets can significantly reduce water use in your Lakewood home. You can also install smart leak detectors and tankless water heaters for added efficiency. A local plumber can recommend the best options based on your home’s setup and water usage habits.
Older homes in Lakewood often face plumbing issues like corroded or outdated pipes, low water pressure, and frequent leaks. You might also encounter problems with old fixtures, sewer line deterioration, or poor drainage. A professional inspection can help identify hidden issues and recommend upgrades to keep your plumbing system safe and efficient.
To get your plumbing ready for winter in Lakewood, start by insulating exposed pipes, especially in unheated areas like basements and garages. Disconnect outdoor hoses, shut off exterior water lines, and check your water heater for optimal performance. It’s also smart to know where your main shut-off valve is in case of a frozen pipe emergency.
Signs of a damaged sewer line in your home include frequent drain clogs, foul odors, soggy spots in your yard, and gurgling sounds from your toilets or drains.
