Automatic 8-litre water tank for connecting low-pressure poultry drinking systems to a pressurised water supply. Featuring an integrated float valve, a 3/4" water inlet and two configurable outlets at the bottom and side of the tank. Includes one 1/2" hose tail, one 3/4" hose tail and one blanking plug. Permitted inlet pressure: 0.5–6 bar.

This pressure compensation water tank provides a convenient way to supply compatible low-pressure drinkers from an existing water supply. The tank refills automatically, while the connected drinkers receive water at a much lower pressure.

An integrated float valve maintains the water level in the reservoir. When water is drawn from the tank, the level drops and the float valve opens. Once the intended water level is reached again, the valve closes.

This eliminates the need to refill a separate water reservoir manually on a regular basis.

The main advantage of this model is its flexible outlet arrangement: two outlet openings can be fitted with either of the included hose tails or closed using the supplied blanking plug.

Two Configurable Outlets – 1/2" and/or 3/4"

The tank features two water outlet openings, one at the bottom and one on the side.

The following fittings are included:

• 1 hose tail for 1/2" hose

• 1 hose tail for 3/4" hose

• 1 blanking plug

This allows different installation arrangements.

When only one outlet is required, the appropriate hose tail can be fitted and the unused opening closed securely with the blanking plug.

Alternatively, both outlets can be used at the same time, for example to supply two separate hose lines.

The larger outlet sizes make this version particularly useful for drinking systems requiring 1/2" or 3/4" tubing.

Automatic Refilling with an Integrated Float Valve

The mechanical float valve regulates the incoming water without requiring electricity.

The operating principle is straightforward:

1. Connect the 3/4" inlet to a suitable water supply.

2. The float valve maintains the water level inside the tank.

3. Connected drinkers draw water through the configured outlets.

4. As the water level drops, the float valve opens.

5. The tank is automatically replenished until the intended level is restored.

With a capacity of 8 litres, the tank acts as a continuously replenished intermediate reservoir for the drinking water system.

Separating Mains Pressure from Low-Pressure Drinkers

The tank is connected to a pressurised water supply. The permitted inlet pressure is 0.5–6 bar.

The float-controlled reservoir separates the pressurised inlet from the downstream low-pressure system. This means the drinkers are not exposed directly to the full inlet pressure.

Water is supplied through the outlets by gravity when the tank is positioned appropriately.

Suitable for a Range of Low-Pressure Systems

The tank can be used with compatible drinking systems for poultry and small animals, including:

• Automatic low-pressure poultry drinkers

• Low-pressure drinking cups and bowls

• Suitable nipple drinking systems

• Drinking installations with multiple watering points

• Systems using 1/2" or 3/4" water supply hoses

Several drinkers may be connected through suitable distribution fittings.

The actual number depends on water consumption, available height difference, hose diameters, pipe lengths and the flow capacity of the entire system.

Practical Equipment and Compact Design

The tank has an 8-litre capacity and approximate dimensions of 35 × 19 × 15 cm. Allow additional clearance for projecting connection fittings.

The included lid helps protect the stored water from dirt and foreign material.

The package also includes the float valve, seals, both hose tails and the blanking plug.

Installation, Use and Safety

Install the water tank securely and horizontally in a suitable location. For gravity-fed operation, the water level inside the tank must be sufficiently higher than the connected drinkers.

Connect the 3/4" water inlet to a suitable pressurised water supply. The inlet pressure must remain within 0.5–6 bar.

Fit the bottom and side outlet openings with the included hose tails or blanking plug according to the installation requirements. Any unused opening must be securely sealed.

Connect the outlets to compatible low-pressure drinkers using suitable hoses and distribution fittings. Make sure that the available flow rate meets the needs of the animals.

Open the water supply and check that the tank refills automatically and that the float valve closes properly. Inspect every connection for leaks.

Never expose low-pressure drinkers directly to an excessive mains pressure. Also ensure that the gravity-fed system provides enough pressure for the connected drinkers to operate correctly.

Clean the tank and inspect the float valve regularly to prevent deposits and blockages.

When connected to a public drinking water supply, comply with applicable drinking water hygiene and backflow prevention requirements.

Protect the tank, valve and hoses from freezing. Automatic refilling does not replace regular checks of the animals' drinking water supply.
