Faster, Cleaner Installs for RKIN Systems
RKIN installation kits are designed to remove the guesswork from plumbing, whole-house filters, and softeners. Instead of hunting for parts at the hardware store, you get pre-matched stainless steel flex lines and fittings sized for RKIN systems and standard 1" PEX, CPVC, and copper. This can give homeowners a cleaner, faster install, and can save plumbers time on site. Every kit is designed around RKIN engineering standards and backed by the same responsive support team.
What You Get
Simplified Installation
Flex hoses and fittings sized to connect your RKIN whole-house system to the main line. Some plumbing may still be needed at the main line.
Faster Setup, Less Downtime
Flexible stainless hoses and quick connects help you avoid the time-consuming process of perfectly cutting, measuring, and gluing rigid pipe connecting to the water system.
Fewer Leaks and Callbacks
Fewer joints and correctly sized fittings reduce the chances of drips, leaks, and emergency rework later.
Full-Home Benefits Sooner
Your filter or softener comes online faster, so you get better water at every tap, shower, and appliance with less hassle.
Predictable Performance
High-flow, 1" components are chosen to work with RKIN systems without choking pressure when the system is sized correctly for your home.
How It Works
Flexible Stainless Steel Hoses
Pre-cut, high-flow stainless steel flex lines connect your RKIN tank(s) and pre-filter housing to the main water line without requiring precise measurements.
Quick-Connect Ends for Common Pipe Types
Quick connects are sized for 1" PEX, CPVC, and copper, so you can adapt to typical residential plumbing with minimal extra parts.
Matched Nipples and Fittings
Included nipples and connectors are chosen to thread directly into RKIN ZEE Pro housings.
Short, Direct Runs
The kit lets you place the system near the main line and “bridge the gap” with flexible hoses, reducing the need for complex pipe routing.
Compatible with RKIN Whole-House Systems
Different kits are tailored for single-tank, dual-tank, and CBS whole-house systems, matched to flow and fit for each system type.

Who It Is For
Homeowners installing RKIN whole-house carbon filters, softeners, or well-water systems who want a smooth, low-stress installation.
Plumbers who prefer proven, pre-matched parts instead of building a kit from scratch for each job.
City water users dealing with chlorine, taste, and odor issues, and wanting a clean, professional setup.
Well water owners adding iron, sulfur, or hardness treatment and wanting to minimize leak and pressure problems.
Anyone who values protecting their home, saving time, and getting their water system running right on day one.
How to Choose in 3 Steps
Confirm Your RKIN System
Note the exact RKIN whole-house system you’re installing (carbon filter, salt-free softener, salt-based softener, or well-water combo) and the number of bathrooms
Match the Kit to Your System Type
Choose the installation kit that matches your system layout: single-tank, dual-tank, or CBS whole-house system. The product titles and descriptions will call out the compatible models.
Decide Who Will Install
If you’re a confident DIYer, pair the right kit with RKIN’s install guide and basic plumbing tools. If you prefer to hire a plumber, order the kit with your system so your installer arrives with the correct parts and can work faster.
Frequently Asked Questions
Will an installation kit make my water safer or cleaner by itself?
Will an installation kit make my water safer or cleaner by itself?
No. The installation kit does not filter water; it provides the hoses and fittings to connect your RKIN whole-house system. Your water quality improvements come from the filter or softener you install. The kit simply helps you get that system installed correctly and running sooner.
Do I need this if I already have a plumber?
Not required, but many plumbers like the pre-matched parts because they save time sourcing fittings.
Can I just buy parts from the local hardware store instead?
You can, but it often means multiple trips, mismatched fittings, and extra joints that can leak. The RKIN installation kit is pre-matched to our systems and common 1" plumbing, which reduces guesswork and helps maintain good flow and reliability.
Will using this kit reduce my water pressure?
Not when used with a properly sized RKIN system. If you already have low pressure, your plumber can review your plumbing layout for other restrictions.
Can I install my RKIN system myself with this kit?
Many mechanically inclined homeowners can, especially when comfortable turning off the main water and working with basic plumbing tools. The kit simplifies the connections, but you still need to follow RKIN’s installation manual carefully. If you’re unsure, we recommend hiring a professional plumber and giving them the kit.
Does this work with both city and well water systems?
Yes. The installation kits are for the plumbing connections, not the source water. Whether your RKIN system serves city water or well water, choose the kit that matches your RKIN model and tank layout.
Will using the installation kit affect my RKIN warranty?
Your RKIN warranty terms are on our Premium Warranty page. Follow the installation manual and local plumbing codes.
Do I still need a separate drinking water filter?
A whole-house system with an installation kit will improve water throughout your home, but many customers still add a dedicated reverse osmosis or under-sink system for drinking and cooking. This provides an extra level of purification at the kitchen tap, while the whole-house system protects plumbing, appliances, and showers.
