Enjoy Cleaner, Safer Drinking Water at Home

If your tap water tastes weird, smells like chemicals, or leaves a white film on your dishes, you’re not alone. Arizona is known for hard water—and sometimes, it’s not the best for drinking. That’s where a reverse osmosis system comes in.

These systems remove unwanted substances like chlorine, fluoride, and minerals, providing you with clean water straight from the tap. At P&L Plumbing, we install, repair, and maintain reverse osmosis systems for homes across Mesa and the East Valley. Whether you want better water for drinking, cooking, or just peace of mind, we’ll help you get it done right.

The Benefits of Reverse Osmosis

Reverse osmosis, or RO for short, is one of the best ways to clean your water at home. It works by pushing water through a special filter that removes tiny particles—even ones you can’t see or taste. Here’s why so many people choose it:

Cleaner, Better-Tasting Water

Reverse Osmosis filtration removes up to 99% of contaminants, including chlorine, lead, and dissolved solids. You’ll notice the difference immediately — pure, crisp water with no chemical taste or odor.

Healthier for the Whole Family

RO water is safer for kids, pets, and anyone with sensitivities. By filtering out harmful substances, it supports better hydration and overall wellness every day.

Cost Savings Over Bottled Water

Stop spending money on bottled water. A reverse osmosis system gives you unlimited clean drinking water straight from your tap — saving you hundreds each year.

Protects Appliances and Fixtures

Mineral buildup from hard water can damage coffee makers, kettles, and dishwashers. RO systems reduce these deposits, extending the life of your appliances and plumbing.

Enhanced Taste for Cooking & Beverages

Clean water means better flavor. Whether you’re making coffee, tea, soup, or pasta, RO-filtered water enhances the natural taste of your food and drinks.

Compact, Convenient Design

Most reverse osmosis units fit neatly under your kitchen sink and connect to a sleek, dedicated faucet. Easy access, minimal maintenance, and long-term performance — all out of sight but always ready.

Most systems fit under your kitchen sink and connect to a small faucet, so they’re out of the way but always ready for use.

Our Reverse Osmosis Services

Professional Installation

Whether you’re adding a new system or replacing an old one, we’ll make sure everything is installed properly and safely. We install most under-sink reverse osmosis (RO) systems and can work with or without an RO loop in your home. Once it’s installed, we’ll test everything and show you how to use it.

Filter Changes & Maintenance

Filters don’t last forever—and that’s a good thing. It means they’re doing their job. We help you stay on track with filter changes, cleaning, and maintenance, ensuring your system continues to function as it should. If your water flow drops or the taste changes, it’s probably time for a service.

Troubleshooting & Repairs

If something goes wrong, we’re here to fix it. Whether your tank isn’t filling, the water tastes off, or there’s a leak under the sink, our team can diagnose the issue and get your system back up and running quickly.

What a Reverse Osmosis System Removes

Chlorine and fluoride
Dirt, rust, and sand
Lead, nitrates, and heavy metals
Bad smells and funny tastes
Some bacteria and organic compounds

Reverse Osmosis vs. Other Water Filters

There are lots of ways to filter your water—but not all filters work the same. Pitchers and faucet attachments can make minor improvements, but they usually target chlorine or basic particles.

RO systems do a deeper job by removing more types of contaminants, including dissolved solids and metals.

That means better taste, better safety, and fewer surprises in your glass. If you care about what’s in your water, reverse osmosis is worth it.

Great company and great prices. The owner, Kevin, is also a stand-up guy and really looks out for his customers (especially ones that know nothing about plumbing like me). These guys will be my new plumbing company going forward!

Had P&L out for a leak from the washing machine into the drainage pipe in the wall. Kevin took care of it efficiently and told me everything he did. We had him out for a new water heater last year and previous leaks. I always ask for him by name. Thanks guys!

I had an excellent experience with P&L Plumbing. They were professional, arrived on time, and completed the job efficiently with great attention to detail. The pricing was fair and transparent, with no surprises. It's refreshing to work with a company that values quality workmanship and outstanding customer service.

This was the first time I've called P&L Plumbing. I decided to try them after reading reviews on the company. Kevin came over and assessed my situation. I didn't end up needing a plumber, but if I do in the future, I'll be calling P&L and asking for Kevin. He seemed very knowledgeable and wasn't at all high pressure, trying to sell me something I didn't need. Thank you Kevin and P&L!

Given my ignorance, Kevin could have performed and charged me for a big ticket job, but he notice the P-drain was dry and had me pour a couple cups of water into it to stop the bad smell. He was a real pro!

Pre-filters typically need to be changed every 6–12 months, while the main reverse osmosis (RO) membrane usually lasts 2–3 years. We can handle replacements for you or set up a reminder schedule if you prefer to do it yourself.

Absolutely. RO water improves the taste of coffee, tea, and any food that uses water for boiling or steaming. Many homeowners notice a clear difference after switching.
