ضمانة, a brand by Otto Graf GmbH, specializes in sustainable water management and gardening products for homeowners. Their extensive product line includes decorative rainwater harvesting tanks, eco-friendly rain barrels, modular raised garden planters like the Ergo Quadro, and outdoor composting solutions designed to blend seamlessly into residential spaces. Manufactured with a focus on durability and environmental responsibility, many GARANTIA products are made from up to 100% recycled materials.

Whether you are installing an Antique Amphora water butt to collect rainwater, setting up a raised bed for vegetable cultivation, or configuring an indoor drinking water make-up module, GARANTIA provides comprehensive solutions to conserve water and elevate your garden's aesthetic. They offer highly reliable and user-friendly alternatives to traditional gardening equipment.

• How do I connect my GARANTIA rain barrel to the downpipe?

  You will need to mark the connection point, drill a hole using a 44-45mm hole saw, insert the provided rubber grommet seal, and attach the flexible hose from the barrel to your downpipe diverter.

• How do I winterize my GARANTIA water tank?

  To prevent frost damage during winter, you must completely empty the tank. Most models have a residual emptying connection at the bottom that can be unplugged. Also, close the inlet ring on the downpipe filter to stop more water from entering.

• What should I do if my GARANTIA water collector leaks at the tap?

  Ensure the tap is threaded correctly into the pre-threaded opening. Check the rubber seal and consider using Teflon tape around the threads if the tap continues to drip.

• Can I use the top of my GARANTIA Deco Container as a planter?

  Yes, models like the Antique Amphora and the 2in1 water collectors feature an integrated planting cup. Make sure to use the provided geo-textile liner before adding potting soil to prevent dirt from contaminating your collected water.
