Hydro jetting is a professional drain and sewer cleaning method that uses a high-pressure stream of water (typically 3,000 to 8,000 PSI) to blast away grease, scale, tree root intrusion, and debris from inside your pipes. Unlike chemical drain cleaners or basic snaking, hydro jetting thoroughly cleans the entire pipe wall rather than just punching a hole through a clog. It is one of the most effective ways to restore full flow and prevent future backups.
-> Dealing with a stubborn clog or slow drains? Call Courtesy Plumbing to find out if hydro jetting is the right solution.
Hydro jetting is safe for most modern pipes when performed by a trained professional, and that is the key. Before hydro jetting, Courtesy Plumbing uses video camera inspection to assess the condition of your pipes. Severely corroded, cracked, or fragile pipes may not be good candidates for high-pressure jetting, and our team will always recommend the safest and most effective approach based on what we find.
-> Call us to schedule a camera inspection and find out if hydro jetting is right for your system.
For most homes, a professional sewer line cleaning every 18 to 24 months is a solid preventive maintenance schedule. However, homes with older clay or cast iron pipes, large trees near sewer lines, or a history of frequent backups may benefit from annual cleaning. Commercial properties with heavy use typically need more frequent service. Regular cleaning helps prevent the buildup of grease, scale, and root intrusion that causes costly emergency backups.

Repiping means replacing all or most of the water supply pipes in your home or building, typically done when pipes have deteriorated to the point that ongoing repairs are no longer cost-effective. Signs you may need a repipe include persistent low water pressure, frequent pipe leaks, discolored or rust-colored water, pipes that are 40 or more years old (especially galvanized steel), or a diagnosis of widespread pipe corrosion. Courtesy Plumbing offers full copper and PEX repiping solutions for Covina and the San Gabriel Valley.
-> Suspect aging pipes? Call us for an honest assessment at (626) 967-5655.
We offer both copper and PEX repiping, and our team will help you choose the best option for your home, budget, and local building codes. Copper is the traditional choice and is durable, long-lasting, and highly resistant to bacteria. PEX (cross-linked polyethylene) is flexible, faster to install, freeze-resistant, and often more cost-effective. Both options are excellent long-term investments when installed by a licensed professional.
-> Not sure which material is right for your home? Call us and we will walk you through the options.
A slab leak is a leak in the water supply or drain lines that run beneath the concrete foundation of your home. Because the pipes are buried under concrete, slab leaks can go undetected for a long time while silently causing serious structural damage and mold. Warning signs include unexplained increases in your water bill, warm or wet spots on your floor, the sound of running water when no fixtures are on, or cracks in your walls or flooring. Courtesy Plumbing uses advanced leak detection equipment to locate slab leaks accurately before any work begins, minimizing disruption to your property.
-> Suspect a slab leak? Do not wait. Call Courtesy Plumbing at (626) 967-5655.
A tankless (or on-demand) water heater heats water directly as it flows through the unit. There is no storage tank holding pre-heated water. When you turn on a hot water tap, cold water travels through the heater where a gas burner or electric element heats it instantly. This means you never run out of hot water as long as demand stays within the unit’s flow rate. Courtesy Plumbing installs and services Navien tankless water heaters, one of the most efficient and reliable brands available.
-> Interested in upgrading to a tankless water heater? Call us to learn what system is right for your home.
It depends on your household’s needs. Tankless water heaters offer significant energy savings since they only heat water when needed. They also have longer lifespans (20 or more years vs. 8 to 12 for tank units) and deliver endless hot water on demand. Traditional tank heaters have a lower upfront cost and simpler installation. For most homeowners in the San Gabriel Valley who plan to stay in their home long-term, a tankless system delivers a strong return on investment. Our team can help you evaluate which option makes the most sense for your situation.
-> Call Courtesy Plumbing for a no-pressure consultation on the best water heater for your home.
Traditional tank water heaters typically last 8 to 12 years, while tankless water heaters can last 20 years or more with proper maintenance. Factors like water quality, usage volume, and regular servicing all play a role. If your water heater is more than 10 years old and showing signs of rust, leaks, inconsistent temperatures, or strange noises, it may be time for an inspection or replacement. Courtesy Plumbing can assess your current unit and recommend the best course of action.
-> Not sure if your water heater is due for replacement? Call (626) 967-5655 for an honest evaluation.
A whole-house water filtration system is installed at your home’s main water line, treating all the water that enters your property. This means every tap, shower, appliance, and fixture delivers filtered water.

If you are concerned about water quality in the Covina or San Gabriel Valley area, a whole-house system is one of the most effective and convenient solutions available.
-> Call Courtesy Plumbing to find out which water filtration system is right for your home.
