The Pipeline Flexible Rain Barrel 400L is a collapsible water butt designed for collecting and storing rainwater for gardens, allotments and growing areas. Combining a generous 400 litre capacity with a flexible, space-saving construction, it provides substantial water storage without the permanent bulk of a conventional rigid water tank.

Collecting rainwater allows gardeners and growers to build up a useful reserve during wet weather for use when conditions become drier. With 400 litres of storage available, this Pipeline Flexible Rain Barrel offers a practical balance between capacity and footprint, making it suitable for both domestic gardens and more productive growing areas.

The flexible cylindrical tank is supported by vertical poles when assembled. When additional water storage is no longer required, the tank can be emptied and dismantled for much more compact transport and seasonal storage.

Why choose the Pipeline 400L Flexible Rain Barrel?

  • Generous 400 litre capacity - provides a substantial reserve of collected rainwater for regular garden watering.
  • Collapsible water butt design - dismantles when empty for convenient transport and storage.
  • Rainwater collection - store rainfall during wetter periods ready for use when plants need watering.
  • Space-saving construction - avoids permanently dedicating space to a bulky rigid 400L tank.
  • Flexible cylindrical body - supported by vertical poles to maintain the tank structure when assembled.
  • Integrated lower outlet - allows convenient access to the stored water.
  • Covered top - helps reduce larger debris entering directly from above.
  • External level markings - provide a useful visual indication of the amount of water stored.
  • Suitable for seasonal use - assemble when additional water storage is needed and pack away afterwards.
  • Versatile garden water storage - ideal for gardens, allotments and other growing areas.

400 litres of practical rainwater storage

The 400L Pipeline Flexible Rain Barrel provides significantly more capacity than a small garden water butt while remaining manageable for locations where one of the largest storage tanks would be unnecessary.

During periods of rainfall, collected water can gradually build up in the tank to create a useful reserve. This can then be drawn upon for watering beds, borders, containers and other planted areas during drier weather.

For gardeners with numerous containers or larger planted areas, the additional capacity can be particularly valuable during the main growing season when water demand increases.

Ideal for gardens, allotments & growing areas

Gardens Collect and store rainwater for watering beds, borders, containers and other planted areas.
Allotments Build up a useful water reserve for crops and plants where convenient water storage is important.
Container growing Provides additional stored water for pots, planters and other container-grown plants during dry conditions.
Growing areas Useful supplementary water storage for regular plant watering and compatible irrigation equipment.
Seasonal use A practical option where additional water storage is required during the growing season but not throughout the entire year.

Collapsible alternative to a rigid 400L water butt

A conventional rigid water butt occupies the same amount of space whether it is full or completely empty. The Pipeline Flexible Rain Barrel offers a more adaptable approach to garden water storage.

The flexible tank body is supported by vertical poles during use, creating a stable cylindrical storage structure. Once empty, the tank can be dismantled so that it occupies considerably less space than an equivalent rigid water tank.

This makes the 400L model particularly useful where water-storage requirements change throughout the year or where garden equipment needs to be packed away between seasons.

Collect rainwater for garden watering

Rain falling onto suitable roof surfaces can provide a valuable source of water for gardens and growing areas. Rather than allowing all of this rainfall to flow directly into the drainage system, a suitable rainwater collection arrangement can divert water into the Pipeline tank for later use.

A 400 litre capacity provides enough storage to make good use of wetter periods. The collected water can then be used for suitable garden watering applications when rainfall becomes less frequent.

This is particularly useful during spring and summer, when plant growth and warmer conditions can substantially increase watering requirements.

Setting up the Pipeline 400L Flexible Rain Barrel

Position the rain barrel on a firm, stable and level surface before filling. Check the ground carefully and remove sharp stones, protrusions and other objects that could damage the flexible base.

Assemble the flexible tank and supporting structure according to the supplied instructions. If collecting water from guttering, use a suitable rainwater diverter or collection arrangement to direct rainfall from the downpipe towards the tank.

Choose the installation position before adding water. A full 400 litre tank contains a substantial weight of water and should be emptied before attempting to move or dismantle it.

Convenient access to stored water

An integrated outlet towards the bottom of the Pipeline tank provides convenient access to the stored water. This makes it easier to draw water when required without repeatedly accessing the tank from the top.

Water can be transferred for use around the garden or with suitable watering and irrigation equipment, depending on the individual setup.

External level markings provide a useful visual reference for monitoring how much water remains available inside the tank.

Seasonal care & storage

Keep the rain barrel and any connected collection system reasonably clear of leaves and other debris. Periodically checking the water inlet and outlet will help maintain reliable operation throughout the season.

When the tank is no longer required, drain the remaining water and allow the flexible body to dry before dismantling it. Store the tank and its supporting components in a clean, dry location away from sharp objects.

The ability to pack the tank down is particularly useful for allotments, seasonal growing spaces and gardens where a permanent large water butt is not required.
