Rain Heads for Rainwater Harvesting

Rain heads are the first line of defence for your rainwater harvesting system. They sit atop your downpipe and filter leaves, moss, and debris before water enters the tank. In the UK, where roof debris from gutters is common, a quality rain head is essential for maintaining water quality and preventing your tank from becoming a collection point for organic matter.

Compatible with 68mm and 80mm downpipes standard in UK properties, our rain heads are manufactured from UV-stabilised materials designed to withstand the British climate. They feature a stainless steel mesh screen that captures debris while allowing water to pass through freely. The angled design ensures that filtered debris falls away from the inlet rather than building up around it.

For UK homeowners and businesses collecting rainwater, a rain head is a small investment that delivers significant returns. Without one, your tank will accumulate sludge from roof debris, reducing storage capacity and making water treatment more difficult. Rain heads also prevent leaves from clogging downstream pipework and pumps, reducing maintenance requirements across your whole system.

Our range includes models suitable for both domestic and commercial applications, with flow rates designed to handle UK rainfall intensities. Whether you are fitting a new system or upgrading an existing one, installing a rain head is one of the most cost-effective improvements you can make.

Rain heads work alongside other filtration components such as tank screens and first flush diverters to form a complete water quality management system. For properties with high roof runoff, consider our Maelstrom vortex range for enhanced self-cleaning performance.

UK Building Regulations Compliance

Our rain heads are designed to meet the requirements of Building Regulations Approved Document H, which covers rainwater drainage and harvesting in the UK. They are manufactured to BS EN 12056-3 standards for roof drainage and are suitable for use in systems seeking BREEAM or Code for Sustainable Homes credits.
