Epa and NASTeC Certified, Service Specialist. RO Appliance is owned and operated with the upmost respect and professionalism, by certified, knowledgeable and honest technicians, covering south of the Bay Area.

"Ray came out on the Saturday evening of Memorial Day weekend. He replaced the condenser on my GE Monogram fridge, which several other companies had told me they do not work on. I was at a loss as far as what to do until Ray called and said he was in the area, so he would come look, diagnose, and give an estimate. I had to have it fixed as it had already been several days of unsuccessfully trying to find someone to repair it. He had the part in his truck and very efficiently and quickly replaced the part. He was very polite and well informed as well. He told me exactly what he was doing throughout the process, and gave tips on how to keep it running optimally. Very pleased! Highly recommend RO Appliance to anyone! Thank you Ray!"

Sewer main install, replace or repairs FAQs

When installing a sewer line, you should consider extra costs like tree removal, driveway repairs, or patio resurfacing. Hiring a professional plumber is essential, and you may need additional specialists if landscaping or heavy excavation is involved. Addressing these potential extras up front helps ensure accurate budgeting and prevents sudden cost overruns.

To calculate the length of sewer piping you need, measure the distance from your house to the main sewer line, adding the depth of the city main to this distance. Be sure to account for any obstacles like tree roots or utility lines that may require additional piping.

City sewer lines are installed at a lower elevation to prevent unwanted backflow and water damage. This lower positioning ensures enhanced performance and long-term safety, meeting all technical and safety standards.

With trenchless methods, a plumber inserts a smaller pipe within the existing plumbing, avoiding full excavation. It can be more cost-effective and less disruptive than traditional methods, but it's not suitable for all homes.

Yes, you must secure permission from your local water authority before connecting to a public sewer line. This approval ensures your connection meets all regulatory requirements.

Sewer lines are buried between 18 inches and 8 feet deep, with most systems placed between 18 and 30 inches. In colder regions, pipes are set deeper to remain below the frost line.
