Client overview

RainSoft / Aquion Water Treatment / Pentair

RainSoft has been one of America’s most trusted names in residential and commercial water treatment since 1953. Founded in Bensenville, Illinois by John Grayson, RainSoft grew over seven decades into a worldwide brand — manufacturing whole-house water conditioning, filtration, and purification systems backed by the industry’s only lifetime guarantee.

The RainSoft brand operated under Aquion, Inc. (formerly Aquion Water Treatment Products), headquartered in Roselle, Illinois. Aquion served as the manufacturer and marketer of a broad portfolio of water treatment solutions across residential and commercial markets, with RainSoft and Erie Water Treatment as residential brands and OptiPure and ClearWater Tech serving commercial customers. Aquion reported revenues of approximately $72 million in 2018.

In February 2019, Pentair plc — a publicly traded global water treatment company (NYSE: PNR) with operations in 34 countries and roughly 10,000 employees — acquired Aquion for $160 million, bringing RainSoft into one of the world’s leading water treatment enterprises. RainSoft continues to operate today as a division of Aquion under the Pentair umbrella.

At the heart of the RainSoft business model is an independent dealer network — more than 150 dealers worldwide operating exclusive sales territories, supported by RainSoft’s training programs, lead generation infrastructure, consumer financing, and dealer services. Managing that network at scale, across geographies and ownership transitions, required digital infrastructure equal to the complexity of the business.

That’s where 305 Spin came in.

HOW THE RELATIONSHIP GREW

Twenty years. One continuous partnership.

305 Spin’s relationship with RainSoft began in 2004 as a web development and support engagement. Over two decades — through two ownership transitions, a migration to cloud infrastructure, and an ERP integration with a Fortune-level parent company — that relationship has grown into one of the most technically complex and enduring partnerships in 305 Spin’s history.

THE WORK IN DEPTH

What 305 Spin built and manages.

Pipeline — RainSoft’s Dealer Extranet

Pipeline is the operational hub of the RainSoft dealer network worldwide. Built by 305 Spin in 2007 and continuously developed since, it is a full-stack enterprise web application serving two distinct user populations — internal RainSoft and Pentair corporate employees, and external independent dealers — through a unified platform with role-based access controls that determine what each user can see, do, and report on.

Core capabilities of the Pipeline portal include:

Order entry — dealers submit product orders directly through Pipeline, which connects to inventory and fulfillment workflows

Warranty card registration — dealers register installations for each customer, activating RainSoft’s lifetime warranty and building the customer database

Rewards and points system — RainSoft’s dealer incentive program is administered through Pipeline, tracking points earned from sales volume and customer satisfaction metrics and enabling dealers to redeem rewards

Convention and conference registration — a custom-built registration system handles national and international dealer events, from registration intake through logistics management

Reporting and analytics — role-based dashboards and reports give corporate teams visibility into dealer performance, sales trends, and operational metrics

Lead management — multiple public-facing RainSoft websites feed leads directly into Pipeline’s central database for routing to the appropriate dealer by territory

Pipeline is built on an Angular frontend with a .NET backend and SQL Server database. The system connects to RainSoft’s on-premises network via direct SQL connection for data exchange, and exposes multiple APIs for communication with both internal Pentair systems and external third-party integrations.

JD Edwards Integration — Pentair ERP

The most technically complex recent engagement was the integration of Pipeline with Pentair’s JD Edwards ERP system. JD Edwards is an enterprise-grade Oracle platform used by large organizations to manage accounting, inventory, ordering, and financial operations at scale.

This integration required 305 Spin to build an API bridge between Pipeline’s existing data architecture and Pentair’s JD Edwards environment — enabling order data entered by RainSoft dealers in Pipeline to flow directly into Pentair’s accounting and ordering processes without manual re-entry or data reconciliation.

The result: RainSoft is now fully integrated into Pentair’s enterprise operations. Dealer orders placed through Pipeline appear automatically in Pentair’s financial and inventory systems, eliminating the operational gap that had existed between the dealer-facing platform and the parent company’s back office.

RainSoft.com, 60+ Dealer Websites & Brand Properties

Beyond Pipeline, 305 Spin manages the full RainSoft web ecosystem:

RainSoft.com — the national consumer-facing website, handling brand marketing, product information, and consumer lead generation for the North American and international audience

60+ dealer-specific websites — individually managed sites for RainSoft dealers across the US and internationally, each reflecting the dealer’s local brand presence while maintaining RainSoft’s national standards

RainSoft dealer recruitment website — a dedicated site supporting RainSoft’s dealer acquisition efforts, attracting and qualifying prospective new dealers

Additional brand websites — several other RainSoft and Aquion brand properties hosted and maintained by 305 Spin

All sites in the ecosystem are connected to Pipeline’s central lead database, ensuring that consumer inquiries generated through any RainSoft web property are captured, attributed, and routed to the appropriate dealer automatically.

305 Spin handles all hosting, ongoing maintenance, content updates, and technical support for these properties — coordinating directly with RainSoft’s Sales and Marketing teams and Pentair’s IT organization to keep a complex multi-site ecosystem running smoothly.

WHAT THIS ENGAGEMENT REPRESENTS

More than a vendor. A long-term technology partner.

The RainSoft relationship is one of the clearest illustrations of what 305 Spin actually is and how it works best. It started as a website support engagement in 2004. Within three years it had grown into the design and development of a mission-critical enterprise application — one that today sits at the center of how RainSoft manages its entire worldwide dealer network.

Over 20 years, 305 Spin has navigated two ownership transitions — from Aquion’s independent operation through Mason Wells’ private equity ownership to Pentair’s global enterprise — without losing continuity or performance for the dealers who depend on Pipeline every day. That kind of institutional knowledge — of the platform, the business model, the data architecture, and the people — is not something you rebuild with a new vendor.

When Pentair needed Pipeline integrated with JD Edwards, they came to 305 Spin. When RainSoft needs a dealer’s website updated, they come to 305 Spin. When a new dealer joins the network and needs a site live, 305 Spin handles it. The relationship has outlasted software generations, corporate acquisitions, and more than two decades of technology change — and it continues to evolve.
