1/2" stainless steel automatic nipple drinker for anti-waste wet/dry feeders – Model FDA-000015ETP

Product description

The FDA-000015ETP nipple drinker for wet/dry feeders is designed for combined swine feeding systems, where water and feed are consumed directly in the feeder.

This FDA-000015ETP nipple drinker for wet/dry feeders with a 1/2" threaded connection allows for controlled water delivery that moistens the feed, improving palatability and encouraging feed intake by the animals.

The brass body and thread ensure high corrosion resistance, long-term reliability, and a proper hydraulic seal.
The 25 mm hexagon allows for stable and secure screwing onto the feeder.

The Ø 24 mm stainless steel activation knob of the FDA-000015ETP nipple drinker for wet/dry feeders is designed to be activated by the swine during the natural movement of its head in the feeder. The movement of the knob triggers a slight and controlled water flow, which moistens the feed and helps reduce waste.

This version of the FDA-000015ETP nipple drinker for wet/dry feeders is equipped with an adjustable plastic filter, which allows the water flow rate to be adjusted based on the pressure in the water line, improving flow control.

Installation heights and angle

The indicated heights are general guidelines.
We recommend using three installation heights or height adjusters to adapt the position of the nipple drinker for wet/dry feeders to the different growth stages of the animal.

The FDA-000015ETP drinker can be installed at an angle between 15° and 45°:

• 15° → use the lowest height

• 45° → use the highest height

This adjustment ensures correct posture for the animals and helps reduce water waste.

Recommended water pressure

The maximum water pressure must not exceed 4 bar (55 psi) to ensure correct system operation.

For piglets and weaned piglets, the pressure should not exceed 2 bar (28 psi).

Lower pressures promote:

• water savings

• longer life for seals and spring

• flow regularity

• ease of use

• waste reduction

👉 We recommend using a pressure reducer if the water line has high or unstable values.

Water flow rate

👉 (CLICK HERE) for the flow rate table

The flow rate of the 1/2" automatic nipple drinker for swine varies according to the pressure in the water line.

For optimal system operation, a flow rate between 0.6 and 1 L/min is recommended to achieve correct feed moistening, reducing water waste and keeping the feeding area cleaner.

In the version with an adjustable filter (model FDA-000015ETP), the flow rate can be adjusted via the valve cap, allowing the flow to be adapted to the pressure available in the system.

The graph highlights three valve adjustment levels:

• Level 1 (4–9 bar) – green zone
  used when the system pressure is high.

• Level 2 (2–4 bar) – blue zone
  suitable for systems with medium pressure.

• Level 3 (0–2 bar) – gray zone
  ideal for drinking lines with low pressure.

The graph allows you to quickly identify which level to set on the valve cap to obtain a stable flow rate for the nipple drinker for wet/dry feeders based on the pressure available in the system.

With correct adjustment, the flow rate remains around 1.0 L/min, ensuring a constant and reliable flow.

Water contamination

Contamination of water or pipes can be one of the main causes of malfunction in swine nipple drinkers over time.

To prevent this problem, we recommend installing a filter on the water line inlet to trap any impurities and ensure smooth operation of the system.
