Plumbing System Installation Process
We carefully check your site, design a system based on your needs, and then install everything with strict quality checks.
1. Consultation and Site Assessment
We start by visiting your property to review the site conditions. This means checking available water lines, sewer connections, and gas access points. We also look at your ADU’s layout and space limitations.
2. Custom System Design
After the site assessment, we create a plumbing system tailored for you. This design includes plans for water, gas, and sewer pipe layouts. We select pipe sizes and materials that match your ADU’s size and usage.
3. Professional Installation and Testing
With your approval, we move to installation. We bring all the required pipes, fittings, valves, and fixtures to your site. Our team installs everything carefully to avoid leaks or future problems.
4. Post-Installation Inspections
After we finish installing your plumbing, we conduct a full inspection. This means testing all pipes, connections, and fixtures to catch leaks or pressure problems early.
5. Service Guarantees
Our warranty covers faulty materials and poor workmanship for a set period, usually one year. This includes leaks, broken parts, or installation errors in plumbing lines, valves, and fixtures.
Plumbing Solutions We Offer
Eco-Friendly Plumbing Options
We install plumbing that helps conserve water and reduce waste. This includes low-flow faucets, showerheads, and toilets designed to use less water without sacrificing comfort.

In addition, we integrate materials that last longer and resist corrosion, which lowers the need for repairs. Sustainable piping options, such as PEX tubing, are common in our installations because they reduce leaks and save energy used for heating water.
Solar water heating systems are another option we provide. These reduce utility costs by using the sun to warm your water, cutting down on energy bills and greenhouse gas emissions.
Smart Water Management Systems
We offer systems that give you control over water use through technology. Smart water valves and sensors detect leaks early and can shut off water automatically to avoid damage.

Our installations can include apps that let you monitor water use from your phone. This helps you track consumption and find ways to save.
We also set up efficient irrigation systems for outdoor areas, helping you maintain your landscaping with minimal water waste. These systems adjust watering schedules based on weather to keep your yard healthy without using extra water.
Residential and ADU Plumbing
We specialize in both traditional residential plumbing and the specific needs of ADUs. ADU plumbing often differs because of space limits and separate water and sewer lines. We understand these details and use the right techniques for detached or attached ADUs.

Our team handles all pipe installations, water heaters, and fixtures to match your unit’s size and purpose. We coordinate with utility companies for water and sewer connections, so you don’t have to worry about delays or mistakes.

We provide plumbing system installation services across California, focusing mainly on urban and suburban areas where Accessory Dwelling Units (ADUs) are in high demand. Our main service zones include Los Angeles, Sacramento, and nearby communities.
In Los Angeles, we cover both residential neighborhoods and new developments. We work with homeowners who want to add ADUs or improve existing plumbing. This area requires us to meet strict city codes, which we handle with care.
