East Valley municipal water is safe, but it can carry a strong chlorine taste, sediment, and dissolved solids that affect your drinking water and your appliances. A reverse osmosis system installed under your kitchen sink provides crisp, bottled‑quality water at a dedicated faucet. For whole‑home protection, a whole‑house filtration system removes chlorine, sediment, and other contaminants before water ever enters your pipes.
Our plumbers specialize in multi‑stage RO installation, selecting the right combination of sediment, carbon, and membrane filters for your water chemistry. We test your water first, explain exactly what's in it, and recommend the most effective contaminant reduction strategy for your family and budget.

Our RO & Filtration Installation Process
We test your tap water for TDS, chlorine, hardness, and contaminants. We'll discuss your water goals — drinking, cooking, whole‑home protection — and recommend the perfect system.
Based on your water test and daily usage, we size the RO membrane (typically 50‑75 GPD for families), select the number of stages, and decide if a whole‑house pre‑filter is needed. You get a flat‑rate quote, no surprises.
Our licensed plumber mounts the RO unit under the sink, drills a small hole for the dedicated faucet (if needed), connects to the cold water line, and runs the drain saddle. For whole‑house filters, we install at the main water line with a bypass valve.
We flush the system, check for leaks, and test the output water quality. You'll learn how to monitor TDS, change filters, and sanitize the system. We also schedule your first annual maintenance.

Reverse Osmosis & Filtration FAQs
An RO system pushes water through a semi‑permeable membrane that removes up to 99% of dissolved solids, chemicals, and contaminants. Water passes through multiple stages — sediment filter, carbon filters, the RO membrane, and a final polishing filter — before reaching a dedicated faucet. The result is clean, great‑tasting water.
A reverse osmosis system is typically installed under the kitchen sink to provide drinking water at a single faucet. A whole‑house filter is installed at the main water line and treats all water entering your home — showers, laundry, and appliances included. Many homeowners install both for comprehensive protection.
Under‑sink RO installations typically range from $450 to $1,200, depending on the number of stages and brand. Whole‑house filtration systems range from $900 to $2,500. We provide a free, detailed quote after testing your water.
A quality multi‑stage RO system reduces or removes chlorine, chloramines, lead, arsenic, nitrates, fluoride, sediment, rust, and many other dissolved solids. It also improves taste and odor. We'll show you a contaminant reduction chart specific to the system we recommend.
Pre‑filters (sediment and carbon) should be changed every 6‑12 months. The RO membrane typically lasts 2‑5 years, depending on water quality and usage. We offer a filter replacement service and can set you up on an annual maintenance plan.
Yes. A whole‑house carbon filter effectively removes chlorine and chloramine, eliminating the smell and drying effects from your showers and baths. Your skin and hair will feel noticeably softer.
Yes, and we often recommend pairing them. The softener protects the RO membrane from hard water scale, extending its life. We can install both systems or integrate a new RO into your existing softener setup.
