Drainage Upgrade - Dee Why

Drainage Upgrade to house & granny flat

We just wrapped up a drainage upgrade at Dee Why. The old system connected to the granny flat was installed incorrectly, with sections separating and causing seepage, no fall causing constant paper blockages, the kitchen line was connected below the level of the gully water and the shower was lacking a trap, which meant that bathroom constantly smelled.

Our team excavated and exposed all existing lines, replaced and re-graded the drainage, and connected new pipes for the shower, kitchen, basin, and toilet. We installed a new overflow relief gully, linked it to the laundry tub and floor waste, and added and installed a trap for the granny flat shower.
