Product Information

Full details

This 350L Prosperplast Tower Stone rainwater tank is ideal for eco-conscious gardeners seeking to reduce mains water consumption and maintain a healthy garden. Its natural stone aesthetic complements outdoor spaces, while the durable, weather-resistant plastic ensures longevity. A key benefit is its integrated downpipe filter and connector, making installation straightforward. The primary caveat is its slimline design, which might offer less capacity than bulkier models for very large gardens.

FAQs

What is the purpose of the downpipe filter?

The downpipe filter collects leaves, moss, and other debris from your roof and downpipe before the water enters the tank, ensuring cleaner stored water and preventing the tank's inlet from becoming blocked.

Do I need a stand for this water butt?

While not strictly required, a stand is highly recommended. It elevates the tank, making it easier to fill watering cans or connect hoses, and it also improves water pressure when dispensing.

How often should I clean the filter?

It is recommended to check and clean the filter at least twice a year, typically in late spring after pollen season and in late autumn after leaves have fallen. More frequent cleaning may be needed in areas with many trees.

Can I drink the collected rainwater?

Rainwater collected in this manner is generally suitable for garden use only. It is not recommended for drinking due to potential contaminants from the roof and atmosphere.

What happens in winter?

To prevent frost damage, it is advisable to drain the water butt completely before the first frost. Disconnect the downpipe connector and store the tank appropriately if severe frost is expected.

How do I connect it to my existing downpipe?

The water butt includes a connector designed for standard downpipes. You will typically need to cut your downpipe at the appropriate height and fit the connector between the downpipe sections and the tank inlet.

Troubleshooting

Water butt is not filling up

Check that the downpipe connection is secure and that the downpipe itself is clear of blockages. Ensure the tank's inlet is not obstructed.

Tap is leaking

Tighten the tap connection. If the leak persists, check the washer or seal for damage and replace if necessary.

Water appears dirty

Clean the downpipe filter and ensure the tank lid is securely in place to prevent debris from entering. Rinse the tank if necessary.

Tank appears unstable

Ensure the tank is placed on a level and solid surface. Use a water butt stand to elevate the tank and provide a more stable base.

Setup, Compatibility & Care Instructions

Setup:

  1. Choose a level, stable location for the water butt, preferably on a raised platform or stand (sold separately) to allow for easier access to the tap and to improve water pressure.
  2. Position the tank adjacent to a suitable downpipe. Ensure the downpipe is cut at the correct height to connect to the tank's inlet.
  3. Attach the included downpipe connector to the cut downpipe and then connect it to the water butt's inlet.
  4. Install the tap at the base of the water butt, ensuring a watertight seal.

Compatibility:

  • This tank is designed to connect to standard UK and European downpipes. Modifications may be required for non-standard downpipe sizes.
  • Ensure the ground or stand supporting the tank is level and can support the weight of 350kg (water weight).

Care:

  • Regularly clean the downpipe filter to prevent blockages. Remove accumulated debris.
  • Periodically inspect the tank for any damage and clean the interior if necessary, using a mild detergent and water. Avoid abrasive cleaners.
  • During winter, drain the tank completely to prevent frost damage.
