Sumps serve a similar purpose to rainwater heads and are usually found between a box gutter and the downpipe.
Sumps control the amount of rainwater that can be discharged into the stormwater drainage system and prevent damaging overflows or surges.
Sumps can also serve as convenient places to add filtration units for removing dust and leaf debris.
This can be especially important if you intend to use your roof as a rainwater collection area for drinking purposes.
Sumps are commonly available in stainless steel, zincalume, colorbond, and galvanised steel or copper.
It’s important to choose the right size sump for potentially intense rainfall events.
