4. Setup and Installation
The Bushman 130 Gallon Slimline Rainwater Harvesting Tank is designed for straightforward installation. Follow these steps to ensure proper setup.
4.1 Site Preparation
- Location: Choose a location that is level, stable, and close to a downspout or rainwater collection point. The slim design is ideal for placement against a wall or fence.
- Foundation: Prepare a solid, level foundation such as a concrete pad, compacted gravel, or sturdy pavers. The foundation must be able to support the tank's weight when full (approximately 1085 lbs / 492 kg).
- Clearance: Ensure adequate clearance around the tank for maintenance and access to fittings.
4.2 Connecting to Downspout
- Diverter Installation: Install a rain barrel diverter (sold separately) into your downspout according to the diverter manufacturer's instructions.
- Hose Connection: Connect a flexible hose from the diverter to the inlet port on the top of the Bushman tank. Ensure a tight seal to prevent leaks.
- Strainer Basket: Place the included strainer basket into the top opening of the tank to filter debris from incoming rainwater.
4.3 Overflow Management
- The tank includes a 3-inch overflow fitting with a screen. Connect a hose to this fitting to direct excess water away from your foundation.
- Ensure the overflow hose is sloped downwards and discharges water to a suitable drainage area, away from buildings.

5. Operating Instructions
Once installed, operating your rainwater harvesting tank is simple.
- Collection: Rainwater will automatically flow from your downspout, through the diverter, and into the tank. The strainer basket will help prevent larger debris from entering.
- Water Usage: Use the spigot (if included or installed) at the bottom of the tank to access collected water for gardening, washing, or other non-potable uses.
- Monitoring: Periodically check the water level and ensure the overflow is functioning correctly during heavy rainfall.
6. Maintenance
Regular maintenance ensures the longevity and efficiency of your rainwater harvesting tank.
- Strainer Basket Cleaning: Regularly remove and clean the strainer basket to prevent clogging and ensure efficient water flow into the tank.
- Tank Cleaning: Periodically drain the tank and rinse out any sediment buildup. A mild soap solution can be used for cleaning, followed by thorough rinsing.
- Overflow Check: Ensure the overflow pipe is clear of obstructions and directs water away from the foundation.
- Winterization (in freezing climates): Before freezing temperatures arrive, completely drain the tank and disconnect it from the downspout. Store any hoses or accessories indoors. Leaving water in the tank during freezing conditions can cause damage.
- Leak Inspection: Annually inspect all connections and the tank body for any signs of leaks or cracks.
