The bailey universal drain cleaner plunger in 150mm 6 inch size is designed for tackling larger drainage systems and more substantial blockages in commercial and industrial applications. This larger diameter provides increased water displacement and pressure build up, making it highly effective for clearing stubborn obstructions in bigger pipes. The 150mm plunger is particularly well suited for main drainage lines, larger commercial waste systems and heavy duty drainage work where maximum clearing force is required. Its increased surface area generates greater hydraulic pressure to shift more challenging blockages efficiently.
