The cup plunger has several given names: the classic plunger, original plunger, plumber’s friend and sink plunger.
A cup plunger looks like a half cut ball on a handle
It is usually the first type of plunger that comes to mind when plunging applications arise.
Cup plungers may come in a variety of colours, cup and handle sizes.
The colour has no effect on the plunger’s performance – simply pick your favourite!
Cup diameter
The cup diameters are available sized at a large 120mm (4 ¾ “), medium size of 100 mm ( 4″) and smallest size of 75 mm (3”).
Different manufacturers will provide different sizes of cups for the plunger.
Handle length
Depending on the manufacturer, the handle length of the plunger may vary. Some may offer a larger size cup on a small handle, whilst others may offer a smaller cup on a longer handle.
There is plenty of variety to be found, all you have to do is decide which is better suited to your needs (e.g. in a small confined space, a plunger with a shorter handle would be better suited as a longer handle would take up more space and make plunging a bit tricky).
