Everything You Need to Harvest Rainwater at Your Off-Grid Cabin

This package brings together every major component of a functional underground rainwater harvesting system — pre-filtration, pumping, disinfection, and final filtration — in a single, coordinated kit. It's designed for off-grid cabins where reliability and self-sufficiency aren't optional.

Select your pump voltage (115V or 230V) and the number of Monjolin pre-filters based on your downspout count. A layout drawing is included to guide your installation.

Key Features

Monjolin Mini Pre-filter — one per downspout; select quantity at checkout
Springer Series Traditional Pump Kit — on-demand pressure with minimal power draw; available in 115V or 230V
Quantum Disinfection Unit — UV-based treatment for potable water confidence
20" × 4.5" Two-Stage Filter Housing Kit — final sediment and carbon filtration before point of use
System layout drawing included — engineered for underground plastic tank installations
Free phone support included with purchase — we walk you through installation

The Springer Traditional pump kit pressurizes on demand and only draws power when the pressure tank needs to recharge — well-suited for solar or generator-backed off-grid setups.

Note: Storage tank and tank accessories are sold separately. Contact us for a freight quote.

Recommended tank accessories for plastic tank installations:

Mozzie Stoppa Flap Valve 4" — pest exclusion for overflow pipe
4" Tank Penetration Gasket — inlet and overflow piping
1" Tank Penetration Gasket — water and electric lines to structure
2" Tank Penetration Gasket — tank vent penetration
2" Tank Vent Cap — above-ground venting as tank fills and empties
