Water butt questions

Can I order these water butts online?

Yes. Order online and choose collection from UK Flow Centre, Sevenoaks. All products in this Ecosure range, including accessories, are currently collection only. Wait for your collection confirmation before travelling.

Which water butt size should I choose?

Start with the available space, the roof area feeding the downpipe and how often you water. The range runs from 105 to 1,500 litres. Check the actual height, length, width or diameter on the listing, rather than choosing by capacity alone.

What is a water butt planter?

It combines a rainwater storage tank with a planting bowl at the top. The planting bowl does not mean the plants are automatically irrigated. Check the instructions for the exact model before planting or making connections.

Are taps, diverters and stands included?

Only where the product listing explicitly includes them. The 1,500 litre Pillar kit includes a tank, tap kit and downpipe diverter supplied as separate items. The 825 and 1,200 litre Pillar listings are tank only. The galvanised stands are separate products and do not include a tank or tap.

Which rapid tap kit do I need?

Match the kit to the tank outlet. We list ½ inch, ¾ inch and 1 inch BSP kits. Each includes a tap and PTFE tape. The ¾ inch and 1 inch kits also include a hexagon bush; the ½ inch kit does not.

Will a water butt run my sprinkler or dripline?

A gravity outlet may suit filling a watering can, but it does not provide mains-like pressure. Check the required pressure and flow of the watering equipment. A suitable pump, filtration and controls may be needed for a pressurised system.

Does the tank need a base or stand?

Follow the tank manufacturer's instructions. Ground-standing models need a firm, level base and the specified support. Use only the stand made for your model. A wall-mounted tank needs a suitable wall and correctly specified fixings for the filled weight.

Is collected rainwater drinking water?

No. These listings are for garden rainwater storage and non-potable use. Do not use collected roof runoff as drinking water.
