|---|
The Oase LevelControl Auto Top Up System automatically maintains a stable water level in ponds, koi ponds and water features using a conductive sensor and 12 volt solenoid valve. Designed for both gravity fed and pump fed systems, it compensates for evaporation, splash out and drum filter cleaning cycles. With low 3 watt power consumption and 10 mm switching accuracy, it provides reliable long term level control.

Oase LevelControl Auto Top Up System
Automatic Water Level Management for Ponds and Water Features
Maintaining a stable water level is essential for both visual appearance and filtration performance. The Oase LevelControl Auto Top Up System provides a fully automatic and reliable solution for keeping ponds, koi ponds, fountains and reservoirs at a consistent depth.
Manufactured by Oase, this electronically controlled system continuously monitors water levels and adds fresh mains water when required. A partially submerged conductive sensor detects changes in water depth and communicates directly with the control unit. If the level drops by approximately 10 mm due to evaporation, splash out or routine filter cleaning, the controller opens the supplied 12 volt solenoid valve and allows water to enter the system.
Once the correct level is restored, the unit immediately closes the valve. As a result, it prevents overfilling while reducing unnecessary water usage. This automated process removes the need for manual top ups and ensures consistent operating conditions throughout the year.
Suitable for Gravity Fed and Pump Fed Systems
The Oase LevelControl is particularly well suited to gravity fed pond systems. In these installations, even small fluctuations in water level can affect skimmer performance, bottom drain efficiency and filter stability. Therefore, maintaining a constant water height helps protect pumps and supports balanced circulation.
However, it is equally valuable on pump fed ponds, especially those running drum filters. During each automatic cleaning cycle, drum filters discharge waste water to drain. Over time, this regular flushing can gradually lower pond volume. By installing an automatic top up system, water lost during rinse cycles is replaced automatically, ensuring stable water levels without constant supervision.
Koi ponds benefit significantly from this consistency. In warm weather, evaporation can reduce levels quickly. In addition, backwashing and drum cleaning remove water daily. The LevelControl compensates for these changes immediately.
Decorative fountains and commercial water displays also rely on stable water levels. Many fountain nozzles require precise depth to maintain the correct spray pattern. Consequently, consistent topping up ensures visual performance remains unchanged.
The weatherproof control unit allows safe outdoor installation. However, the solenoid valve must be fitted in a splash protected location to ensure long term reliability.
With very low power consumption of approximately 3 watts, the system operates efficiently and economically.

Choosing the right pump setup
When choosing a pond pump, the number on the box is only the starting point. Real flow is affected by head height, pipe length, bends, hose diameter, valves, UV units and the filter it is feeding. A pump that looks powerful on paper can lose a lot of performance if it is pushed through undersized hose or a restrictive run of fittings.
For best results, plan the pump, filter, UV and return pipework together. Use larger bore hose or pressure pipe where possible, keep bends sensible and leave enough access to remove the pump for cleaning. This gives the equipment a better chance of delivering the flow the pond actually needs.
Maintenance and compatibility checks
It is worth checking the supporting parts at the same time as the main product. Hose size, pressure pipe, valves, unions, UV units, filter inlets, air manifolds, spares and cleaning access can all affect how well the final system works. A correctly matched installation usually performs better and is easier to maintain than one built from parts chosen separately.
Aeration setup notes
Oase LevelControl Auto top-up system should be chosen as part of the complete air system, not just by litres per minute. Airline length, airline bore, diffuser depth, manifold taps and back pressure all affect the real airflow that reaches the pond or filter. A well matched aeration system runs more quietly, puts less strain on the pump and gives more dependable oxygen support.
- Use suitable airline size for the pump output and distance involved.
- Keep the air pump dry, ventilated and protected from flooding.
- Spread airflow across multiple diffusers on larger ponds where possible.
- Check diaphragms, filters and diffusers during routine servicing.
For koi ponds, moving bed filters and warm weather aeration, consistent airflow is often more useful than simply oversizing the pump. Balanced diffuser placement gives better circulation and helps avoid stagnant areas.
