When it comes to livestock hydration, it’s easy to focus on trough size or drinker capacity. But the real hero in the system is often overlooked: the valve assembly, particularly the ball cock mechanism. This small but crucial part ensures your animals always have access to fresh water, without waste or overflow.
At Fisher Drinkers, we understand just how essential this mechanism is. For over 100 years, we’ve been providing farmers with durable, dependable hydration systems built around smart, efficient design.
A valve assembly controls how much water enters the bowl. Using a ball cock or float valve, it automatically responds to the water level. When the bowl is full, the float rises and closes the valve. As the water level drops, the float lowers and reopens it. It’s a clever, self-regulating system that requires minimal input once in place.
What matters most is choosing a valve built for the job. That’s where Fisher’s experience comes in.
Fisher Drinkers offers both brass and Zytel-bodied valves to suit different systems.
Our A74 valve assembly, which includes the brass valve body (A31), is standard in models like the A75 Super, A101, and A102. This setup is ideal for mains-fed systems operating under 4 bar pressure and is designed for long service life with excellent resistance to corrosion.
For farms using header tanks, the A44 assembly features a Zytel valve body (A65M). It’s lightweight, chemical resistant, and a more cost-effective option when lower water pressure is in play. Each valve type is selected carefully to ensure the right match for the drinker it supports.
You can easily find and add them to your basket on our website, with full details on delivery options and stock availability.
The right valve helps prevent wasted water, supports livestock health, and keeps maintenance simple. Fisher’s assemblies are made with longevity and ease of replacement in mind, so you’re never left without options when something needs attention.
Our spares range is extensive and built to last. Whether you’re upgrading your system or performing regular maintenance, we’ll help you choose the correct part quickly and confidently.
Dripping, poor flow, or sticky floats can often be resolved with a simple clean or part replacement. Grit and limescale are common culprits, especially in hard water areas. Regular inspections and flushing can help keep everything in good shape.
