Clean, great-tasting water shouldn’t stop at your kitchen faucet. Professional water filtration installation helps improve the quality of the water flowing to every tap, protects your plumbing system, and gives your family greater confidence in the water you use every day.
At Ritz Plumbing, we’ve been helping Los Angeles homeowners since 1931. Looking for a whole-house water filtration system, an under-sink drinking water filter, or a complete hard water treatment solution? Our licensed plumbers provide a professional water filter installation service tailored to your home’s unique water quality.
Southern California’s municipal water meets federal drinking water standards, but that doesn’t mean it’s free from issues homeowners notice every day.
Water often travels through aging infrastructure before reaching your home, picking up sediment and rust along the way. Older household plumbing can also contribute to water quality issues, especially in homes with aging or corroded pipes.
Common concerns include:
Water quality can also vary from one neighborhood to another. Different communities—and sometimes homes just a few miles apart—may receive water from different sources or treatment facilities, resulting in differences in hardness, mineral content, disinfectants, and sediment levels. That’s why professional water quality testing is so valuable before choosing a filtration system.
Many homeowners first notice changes in their water long before a plumbing problem develops.
You may benefit from home water filtration installation if you notice:
If you’re experiencing any of these issues, professional water quality testing can identify what’s in your water and determine which filtration system is the best fit.
While filtration can help improve water quality, rust-colored water may also indicate corrosion inside your home’s plumbing.
Every home has different water quality concerns, which is why we install several types of water purification systems. Each is designed to support the removal of specific water contaminants, from sediment and chlorine to dissolved minerals and other unwanted substances.
A whole-house water filtration system—also called point-of-entry water filtration—treats water before it enters your home’s plumbing.
Benefits include:
Most systems combine:
These systems are installed where the main water line enters your home, so every faucet, shower, washing machine, and appliance receives filtered water.
For homeowners focused on drinking water, reverse osmosis installation provides one of the highest levels of filtration available.
Reverse osmosis systems help reduce:
Installed beneath the kitchen sink, these systems provide drinking water filtration through a dedicated faucet and can also connect to refrigerators and ice makers.
A water softener is different from a filter. Rather than removing contaminants, it provides hard water treatment by removing the calcium and magnesium minerals that cause scale buildup.
Benefits include:
Hard water doesn’t just leave spots on fixtures—it can also reduce your water heater’s efficiency and lifespan by allowing mineral scale to build up inside the tank or on the heating elements. If you’ve noticed inconsistent hot water or reduced water heater performance, our article on no hot water troubleshooting explains some of the most common causes and what to check next.

At Ritz Plumbing, every water filtration installation begins with understanding your home’s water. We evaluate your water quality, plumbing system, and household needs before recommending the right equipment.
Our process includes:
We evaluate your water for:
Water quality testing allows us to recommend a filtration system based on your home’s actual water conditions rather than relying on a generic solution.
We size your system based on:
We also evaluate where the system will be installed, verify there is adequate space for future maintenance, and confirm that the equipment is properly sized for your home’s plumbing and daily water demands.
Our licensed water filtration plumbers install your system using code-compliant fittings, proper bypass valves, and secure plumbing connections to ensure reliable performance. After installation, we test the system, check for leaks, verify proper water pressure and flow, and confirm everything is operating as intended before restoring your water service.
Before your Ritz Plumbing installation is complete, we’ll explain:
Most water filtration systems require periodic filter changes or routine maintenance to continue performing as designed. We’ll show you what to expect, explain the recommended service intervals, and answer any questions before your installation is complete.
Routine maintenance shouldn’t stop with your filtration system. Seasonal plumbing inspections and proper drainage maintenance can also help protect your home.
While many retail filters are marketed as DIY solutions, professional installation provides several important advantages.

That depends on the type of filtration system. Carbon filters reduce chlorine, taste, and odors. Sediment filters capture rust and debris. Reverse osmosis systems remove many dissolved contaminants, including lead and nitrates, while water softeners target hardness minerals.
The cost depends on the type of system, your home’s plumbing, and your water quality needs. An under-sink reverse osmosis system costs less than a multi-stage whole-house filtration system. After testing your water, we provide upfront pricing before work begins.
A water softener treats hard water by removing calcium and magnesium ions that cause scale buildup. A water filter removes contaminants such as chlorine, sediment, and other unwanted substances. Many Los Angeles homes benefit from using both systems together.
The lifespan of a filtration system depends on the type of equipment, your water quality, and how well the system is maintained. Many professionally installed systems provide years of reliable service when filters are replaced according to the manufacturer’s recommendations.
