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.

Frequently Asked Questions
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.
