- Tell us what is happening: leak, no hot water, noise, age, or upgrade goal.
- We inspect the unit, surrounding connections, pressure, venting, and safety parts.
- You receive written options before work starts.
- If replacement is best, we help compare packages, rebates, and warranty choices.
You get options, not pressure.
Many issues can be repaired when the tank is sound and the safety components are working. Replacement usually makes more sense when the tank is leaking from the body, badly corroded, repeatedly failing, or past its expected service life.
Warning Signs You Need Reverse Osmosis
Bitter or Metallic Taste
High total dissolved solids give tap water a distinct bitter or metallic edge that carbon filters alone cannot remove. If your coffee and tea taste off no matter which beans or leaves you buy, the water is usually the culprit. A reverse osmosis membrane strips dissolved solids down to the microscopic level and restores a clean, neutral taste.Cloudy Ice and White Flakes
When ice cubes freeze cloudy and leave white flakes floating in your glass as they melt, you are looking at dissolved minerals coming out of solution. It is harmless-looking but it is the same mineral load coating the inside of your kettle and your coffee maker. Reverse osmosis removes it before the water ever reaches your ice maker.The Bottled Water Habit
If your household refuses to drink from the tap and you are hauling cases of bottled water home every week, a point-of-use reverse osmosis system typically pays for itself quickly — and eliminates the plastic waste along with the grocery runs.What to Expect During Your Service Visit
Our specialist starts with a comprehensive on-site water test at your kitchen sink — hardness, chlorine, total dissolved solids, and pH — so recommendations are based on your actual water chemistry, not a sales script. If reverse osmosis is the right answer, we size the system for your household, install the membrane stages and storage tank to manufacturer specification, route the drain line to code with the required air gap, and verify rejection rates with a dissolved-solids meter before we leave. If your real problem is hardness or chlorine, we will point you to a water softener or whole-house filtration instead — or design a combination where each technology does what it does best.
Already have a reverse osmosis system? We service all major residential brands: filter and membrane replacement, sanitizing, storage-tank air-charge checks, and flow restoration for systems that have slowed to a dribble.

Zak was incredible from start to finish. He walked us through every option, replaced the unit the same day, and left the garage cleaner than he found it.
