Residents of Seven Hills turn to Blocked Drains Parramatta for high-pressure drain jetting. High-pressure jetting scours the inside of a pipe clean, removing fat, sludge and roots rather than just punching a hole through the blockage. Seven Hills is a residential suburb with many post-war homes, as well as an industrial area near the railway line. Because jetting cleans the full diameter of the pipe, drains stay clear far longer than after a basic snake. Jetting is used for household drains, sewer lines, stormwater pipes and commercial drainage, with nozzles matched to the pipe size and the type of blockage. The plumber explains what caused the blockage and what will stop it from coming back. Older homes in Seven Hills often have clay sewer pipes that are prone to root intrusion. Tree root removal and drain repairs are also part of its work. Its service area also includes Baulkham Hills, Toongabbie and Wentworthville.
