What our Clients think about us
Your satisfaction is our priority.
What Are Under-Sink RO and Filtration Upgrades?
An under-sink upgrade usually means:
Removing a basic single-stage “taste” filter or outdated setup.
Installing a multi-stage filtration system (sediment + carbon, etc.) or a reverse osmosis (RO) system for deeper treatment.
Connecting the new system to a dedicated faucet and optionally to your fridge/ice maker.
Compared to simple filters, upgraded systems can:
Provide more thorough impurity reduction.
Improve taste, odor, and clarity more noticeably.
Give you greater confidence in your drinking and cooking water.
Why Choose Active Plumbing

Clean, low-profile installs: We work around disposals, pull-out trash, and tight cabinets.
Integration-friendly: We can reuse good components and tie into fridge lines where it makes sense.
Local, licensed pros: Nevada License #0047021, trusted across the Las Vegas valley since 1991.
Immediate Actions (What to Do Now)
Check what’s under your kitchen sink now—single cartridge, small filter housing, or old RO.
Note what you don’t like about your water (taste, odor, cloudiness, confidence).
Decide if you want sink-only service or to also feed the fridge/ice.
Take a couple of photos under the sink and behind the fridge if possible.
Avoid buying more expensive cartridges until you know if an upgrade makes more sense.
Call Active Plumbing at (702) 438-3357 and ask for under-sink RO and filtration upgrades (single-stage to multi-stage); tell us what’s installed now and what you want to improve.
Common Situations Where Upgrades Make Sense
Your current filter barely changes taste or odor.
You’re replacing cartridges often but still don’t like the water.
You want bottled-like quality without hauling cases of water.
Your under-sink system is old, leaking, or out of support.
You’re remodeling the kitchen and want better water to match the new space.
Under-Sink Inspection & Existing System Check
We inspect what you currently have (single-stage filter, older RO, or nothing), check space, shutoffs, and drain setup, and listen to your water quality goals.
Upgrade Recommendation (Multi-Stage vs RO)
Based on your needs, we recommend either a multi-stage non-RO filter system or a reverse osmosis system, explain the differences, and help you choose faucet-only or faucet + fridge.
Removal of Old Equipment
We shut off water, safely remove the old filter unit, lines, and fittings, and clean up unused brackets, tubing, or parts to make room for the new system.
New System Installation & Plumbing Connections
We install the new multi-stage or RO unit and tank (if RO), connect the cold-water feed, drain line, and faucet, and tie into the fridge line if part of the plan.
Startup, Flushing & Leak Check
We pressurize and flush the new system according to manufacturer guidelines, check all connections for leaks, and confirm proper flow at the faucet (and fridge, if connected).
Homeowner Orientation & Maintenance Plan
We show you what we installed, how it works, and how to shut it off, explain the filter/membrane change schedule, and answer questions about taste, TDS, and everyday use.
What’s Included
Upgrade cost and timing depend on:
Type of upgrade: Multi-stage filter vs full RO system.
Faucet and drilling needs: Using an existing hole vs drilling a new one in the sink or counter.
Fridge connection: Adding or reworking a fridge/ice line.
Complexity of existing plumbing: Older, crowded, or improvised setups may take more time to correct.
We’ll provide a clear estimate before starting, including equipment, labor, and any optional add-ons.

Insurance & Claims Help
Most under-sink upgrades are planned improvements, not insurance items—but under-sink and fridge-connected systems can be involved in leaks if they fail.
If an issue arises, we can:
Identify which fitting, valve, or line is leaking.
Provide itemized repair or replacement estimates.
Answer plumbing-related questions from your adjuster, property manager, or restoration contractor if a claim is involved.
Your insurance company and policy always decide coverage—we provide accurate plumbing documentation.
Risks of Waiting (Why Act Now)
An under-sink upgrade is great for drinking water, but:
It only treats one tap (plus optional fridge), not whole-house hardness or scale.
It doesn’t replace the need for whole-house softening or conditioning if you have hard water issues everywhere.
Filters and RO membranes must be changed on schedule to maintain performance.
Very tight under-sink spaces may limit tank size or system style—we’ll work with what’s realistic.
We’ll be upfront if you also need whole-house treatment in addition to the under-sink upgrade.
Methods, Materials & Quality Standards
Code-compliant connections: We install supply and drain lines per Nevada plumbing code and manufacturer specs.
Neat, organized layout: Tubing and components are arranged to be secure, accessible, and as out of the way as possible.
Quality components: We use reliable valves, tubing, and fittings designed for potable water.
Clear explanations: You’ll know what was removed, what was installed, and how to care for it.
Frequently Asked Questions
Can you reuse my existing faucet for the new system?
Often yes, if it’s in good condition and compatible. If not, we can install a new dedicated faucet.
Do I need RO, or is multi-stage filtration enough?
It depends on your goals. If you want stronger overall impurity reduction and lower TDS, RO is usually better. If you mainly care about taste and basic filtration, a non-RO multi-stage system may be enough.
Will my water pressure at that tap change?
Flow at the filtered/RO faucet may differ from normal tap flow, but we size and install systems to maintain comfortable, usable flow.
Can you tie the upgraded system into my fridge?
In many cases, yes—we can run a line from the under-sink system to your fridge, depending on layout and distance.
What happens to the old system?
We can remove and dispose of old filters, housings, and tubing as part of the upgrade, unless you prefer to keep anything.
Do you offer under-sink RO and filtration upgrades near me in Las Vegas?
