Inside every Bob valve sits a plunger. It is what decides how much water passes and what seals the valve shut when the float lifts. It wears, and when it does the valve stops closing properly. What you are getting 3/4 in. plunger Sized to the Hoskins Bob valve of the same size One per package Order by valve size The plunger has to match the valve, and the valve is set by your model. Goes with the 3/4 in. Bob valve on the 75, 95 and 120 in. cattle tanks and the two longest sheep troughs. Fitment Hoskins C75-16 Hoskins C75-26 Hoskins C95-16 Hoskins C95-26 Hoskins C120-16 Hoskins C120-26 Hoskins SC84-16 Hoskins SC120-16 Start here before buying a valve A waterer that keeps trickling is usually telling you the plunger has had enough, not that the whole valve needs replacing. It is the cheapest part in that compartment and the quickest to swap. Browse the Hoskins parts range, or send us your model number and we will confirm the size.
