Installing your water butt is a breeze, and the satisfaction is unmatched. Follow this step-by-step guide for both decorative and non-decorative models.

Firstly, choose a flat stable surface to put your water butt on. For water butts that have unique shapes or designs that might make them prone to falling down, Garantia offers a solution: wall-mounting brackets. These brackets add an extra layer of stability, ensuring that your water butt stays securely in place. The instructions for mounting these brackets are straightforward and easy to follow.

Connect to the Downpipe:

  1. Drill or cut a section of your downpipe, adjusting as needed.
  2. Insert the capturing system, redirecting rainwater through a smaller pipe to your water butt.
  3. Connect the small pipe from the capturing system to the hole on top of your water butt, creating a direct line to the skies!

Simplicity is Key; Water butt installation is beginner-friendly and doesn’t require advanced skills. Garantia provides a complete installation kit with clear instructions, ensuring a quick setup. In no time, you’ll collect rainwater, reduce your environmental impact, and nourish your garden with nature’s gift – a true win-win for you and your plants!

Connecting Multiple Tanks: Expanding Your Water Storage

Garantia water butts are highly adaptable, and when your rainwater requirements exceed one tank’s capacity, you can easily expand your storage by connecting multiple tanks. This boosts your water storage without complex installations, making it ideal for large gardens or dry periods.

We provide user-friendly connection kits containing hoses, fittings, and connectors for seamless tank linking. They are compatible with Garantia water butt models, ensuring a hassle-free setup.

Linking tanks offers flexibility, allowing you to strategically position them for rainwater capture from various sources. This setup maximises rainwater harvesting, reducing tap water reliance.

Connecting Your Tanks

  • Choose Locations: Pick spots for your additional water butts, ensuring proximity for hose connections.
  • Prepare Tanks: Clean and position each water butt securely.
  • Install Kit: Use the kit to link tanks by attaching hoses and connectors for a leak-free connection.
  • Position Securely: Place connected tanks, level and stable, to maintain smooth water flow.
  • Capture Rainwater: With tanks connected, they collectively capture rainwater, providing a versatile and expanded water storage solution.

Expanding water storage with Garantia is practical and user-friendly, ideal for large gardens or sustainability enthusiasts.

Filtration: Nature’s Gift, Unaltered

In the world of rainwater harvesting, filtration plays a pivotal role in ensuring the quality of the water you collect. Let’s dive into why filtration is essential, how Garantia water butts have you covered, and why it’s crucial not to overdo it.

Rainwater, while pure and refreshing, isn’t immune to picking up some unwanted hitchhikers on its journey from the sky to your water butt. These can include leaves, twigs, dust, and other debris that find their way into your gutter system. Filtration is your first line of defense against these intruders, ensuring that only clean, pristine water enters your storage.

Here’s where the good news comes in – Garantia water butts are equipped with a built-in filtration device. This smart system does the heavy lifting for you, sieving out the larger particles and ensuring that the rainwater that makes it into your butt is of high quality. It’s like having a gatekeeper to keep your water pure and refreshing.

While filtration is crucial to remove debris, it’s important not to go overboard. Rainwater is a gift from nature, containing essential nutrients that are beneficial for your plants. If you filter the water too much, you might unintentionally remove some of these nutrients, making it less beneficial for your garden.

Remember, the water in your water butt is intended to nourish your garden. Stagnant water, which has been sitting for extended periods, can become a breeding ground for bacteria and algae. These unwelcome guests can be detrimental to your plants’ health and growth. To ensure your water stays fresh and your garden thrives, make a habit of regularly emptying and freshening your water butt.

Filtration is like a gentle sieve, allowing the good stuff to pass through while catching the debris. With Garantia’s built-in filtration system, you’re well-equipped to enjoy the benefits of rainwater without the worry of contaminants.

Overflow Prevention

Using a pump with your Garantia water butt elevates your rainwater harvesting experience. It brings efficient watering, convenience, and time-saving benefits to your gardening routine.

Advantages of Using a Pump:

  • Efficient Watering: Easily water your garden with a hose, eliminating the hassle of heavy watering cans.
  • Convenience: Control water flow and pressure, catering to different plant needs.
  • Time-Saving: Skip the chore of filling watering cans, and move water quickly around your garden.

Simple Pump Installation:

  • Hose Connection: Attach your hose to the pump outlet for water flow.
  • Power Source: Some pumps require power. Connect it safely to an outlet or generator.
  • Submersion: Garantia water butts allow direct pump submersion. No additional containers or complex setups needed. Submersion draws water from the bottom, optimizing rainwater use.
  • Operation: Switch on the pump after proper connection and submersion. Your water butt now efficiently supplies your garden.

Draining and Cleaning: Keeping Your Water Butt Shipshape

Your water butt is like a trusty friend, always there to provide your garden with rainwater nourishment. But just like any good friendship, it requires a little TLC from time to time.

Winter is the cue to drain your water butt for two critical reasons:

  • Avoid Ice Damage: Water left inside during freezing temperatures can expand and damage the container.
  • Regular Maintenance: Periodic draining allows for essential cleaning, removing sludge, algae, and grime buildup.

How to Drain Your Water Butt:

  1. Locate the Drain Plug: Typically at the tank’s bottom for user-friendliness.
  2. Remove the Plug: A simple twist or pull will do the trick.
  3. Let It Flow: Gravity takes over, directing water to thirsty parts of your garden.

While empty, give your water butt a thorough cleaning. Remove accumulated sludge, algae, or grime from its interior for fresher, healthier rainwater.

Taking these steps ensures your water butt remains in top shape and ready to serve your garden when warmer weather returns. It’s all about preserving your valuable investment and maintaining a steady water supply for your garden’s needs.

The convenience, efficiency, and eco-consciousness of these water butts make them a valuable addition to any garden, whether you’re an experienced gardener or just starting your green journey.
