High Quality Rainheads and Sumps

Add the finishing touch with stylish, well-crafted rainheads and sumps

Rainheads are an essential design element for buildings where internal box or trough gutters are used. A rainhead or sump is a container located between the gutter and downpipe that aids the flow of water away from the roof. It acts as an external overflow point to reduce water surges into the stormwater system and aid the flow of water down the downpipe. Because rainheads are positioned outside, they minimise the risk of water overflow inside a building. The addition of an overflow provision provides even greater protection against water overflow in extreme conditions.

Rainhead Styles

Box Rainheads

Box rainheads have sharp lines that form bold shapes. With a range of square, splayed or tapered designs to choose from, their style is simple and practical. Box rainheads will complement any form of architecture, but they work particularly well on small commercial buildings or on structures with rendered brickwork.

Tapered Rainheads

Tapered rainheads are popular in industrial applications due to their strength and resilience. Their tapered bottom assists in the natural rotation of the entering water, therefore increasing the efficiency of the rainhead. The bead around the top of the design helps to strengthen the rainhead and protect it from damage during maintenance.

Sumps are usually attached between a box gutter and the downpipe. They collect storm-water before it is carried away by the downpipe and they also serve to catch any debris before it enters the downpipe.

Sumps can be made to order but are commonly manufactured in either 100mm and 150mm depths. They are available in zinc/al, pre-painted colour stell, stainless steel and aluminium.

Rainhead Sizes

When determining the size of your rainhead you will need to consider such things as rainfall intensity, occurrence, use of the building and the size of the box gutter. This is best done by your architect, engineer or building designer and should conform to the requirements of AS/NZS 3500.3:2003 Plumbing and Drainage.

Ordering Your Rainhead

Download the Rainhead Ordering Brochure.

When ordering a rainhead you must specify the dimensions of the design. You will need to know the length, width and height. Depending on the style you choose, you may also need to know the bead height. See below for three examples showing the dimensions you will require.

All rainheads include a fitted downpipe outlet which is available in a wide range of sizes. When ordering your Stratco Rainhead it is important that you specify the size and position of the downpipe outlet.

An overflow provision is also included on all standard Stratco rainheads. The size and position of the overflow needs to be specified when your rainhead order is placed. Overflow spouts are available as optional extras, in round, square or rectangular shapes.
