Kenya’s agriculture sector is rapidly expanding, especially in and around Nairobi, where farmers increasingly rely on efficient irrigation systems, bore well installations, and water pumping solutions to maximize crop productivity. Whether it is horticulture, greenhouse farming, dairy farming, floriculture, or large-scale irrigation projects, maintaining a reliable water supply is critical.
One small but essential component that significantly impacts pump performance is the Foot Valve. A quality foot valve helps prevent water backflow, protects pumps from debris, maintains pump priming, and reduces maintenance costs.
KANA PP Foot Valves are designed to meet the growing demands of Kenya’s agricultural and irrigation sectors. Manufactured from premium-grade Polypropylene (PP), these foot valves are lightweight, corrosion-resistant, UV-stabilized, leak-proof, and available in multiple designs to suit various pumping applications.

What is a Foot Valve?
A Foot Valve is a type of non-return valve (check valve) installed at the suction end of a pump line, typically submerged inside a water source such as:
- Bore wells
- Open wells
- Water tanks
- Ponds
- Rivers
- Reservoirs
The primary function of a foot valve is to:
✔ Prevent water from flowing backward when the pump stops.
✔ Maintain pump priming.
✔ Reduce dry running of pumps.
✔ Improve pumping efficiency.
✔ Prevent suction line drainage.
✔ Stop debris and foreign particles from entering the pump through its built-in strainer.
Without a quality foot valve, pumps may lose prime after every shutdown, resulting in increased electricity consumption, delayed water delivery, and frequent maintenance requirements.
How Does a Foot Valve Work?
When the pump starts operating:
- Water is drawn through the foot valve.
- The valve opens automatically due to suction pressure.
- Water flows into the suction pipe and pump.
When the pump stops:
- The valve closes automatically.
- Water remains inside the suction pipeline.
- Backflow is prevented.
- Pump priming is maintained.
This simple mechanism significantly improves pump performance and extends equipment life.
Importance of Built-In Strainer Protection
One of the most important functions of a foot valve is its integrated strainer.
The strainer helps prevent:
- Sand particles
- Stones
- Leaves
- Mud
- Agricultural waste
- Floating debris
from entering the pump system.
By preventing unwanted particles from entering the pump, the foot valve helps:
- Reduce impeller wear
- Minimize pump choking
- Lower maintenance costs
- Improve pump efficiency
- Extend pump service life
Types of KANA PP Foot Valves
KANA offers three popular types of threaded-end PP Foot Valves suitable for various agricultural and irrigation requirements.
1. Bore Foot Valve
What is a Bore Foot Valve?
A Bore Foot Valve is specially designed for bore well and deep-well applications where reliable water retention is essential.
Features
- Strong threaded connection
- Suitable for borewell pumps
- Lightweight construction
- Durable PP body
- Corrosion-resistant design
- Integrated strainer protection
Applications
- Borewell installations
- Agricultural irrigation
- Domestic water supply
- Groundwater extraction systems
2. Washer Foot Valve (Flap Foot Valve)
What is a Washer Foot Valve?
A Washer Foot Valve, also known as a Flap Foot Valve, uses a rubber washer and weighted flap mechanism.
Working Mechanism
When the pump starts:
- Suction lifts the flap.
- Water enters the suction line.
When the pump stops:
- The flap automatically falls due to its own weight.
- The rubber washer seals the valve opening.
- Backflow is prevented.
Advantages
- Simple mechanism
- Reliable sealing
- Low maintenance
- Long service life
- Cost-effective operation
Applications
- Irrigation pumps
- Agricultural water transfer
- Open well systems
- Water storage pumping systems
3. Spring Foot Valve
What is a Spring Foot Valve?
A Spring Foot Valve uses a spring-loaded mechanism to control water flow.
Working Mechanism
When the pump operates:
- Suction pressure compresses the spring.
- Water passes through the valve.
When the pump stops:
- The spring pushes the sealing washer back into position.
- The valve closes instantly.
- Water backflow is prevented.
Advantages
- Fast response
- Reliable sealing
- Excellent for varying water pressure conditions
- Enhanced pump protection
Applications
- Bore well pumps
- Pressure systems
- Irrigation networks
- Industrial water transfer systems
