Quik Level Water Controller

The use of a water level controller will keep your swimming pool, pond, or water tank at its optimal level. Ideally these should be installed during the pools construction, however the new Vodafill wireless Auto Level control can be retrofitted to any application.

Water Level Control Systems for Pools, Ponds & Tanks

Keeping water at the right level matters — too low and your pump runs dry, too high and water overflows, wastes chemicals and damages surrounding landscaping. Our water level control systems automatically top up pools, ponds, fountains, water tanks and aquariums, so you never have to watch a hose again. At Aqua Clear, we stock both manual float-style fill valves and electronic water level controllers to suit any water feature, pool or tank setup.

Why Install a Water Level Controller?

Automatic top-ups — maintains a constant, pre-set water level 24/7, compensating for evaporation, splash-out and backwashing.
Protects your pump — prevents low-water dry running, one of the most common causes of premature pump failure.
Prevents overflow — stops water waste, chemical dilution and flooding around your pool or pond edges.
Saves time and water — no more manual hosing; most systems pay for themselves in reduced water bills.
Ideal for holidays — keeps levels stable while you're away, making it a favourite for pool owners and holiday rental properties.

Which Type Should You Choose?

Type	Best For	How It Works
Manual Float Style	Swimming pools, ponds, tanks on a budget	A mechanical float opens and closes a fill valve as the water level rises and falls — simple, reliable and no power required.
Electronic Water Level Controller	Fountains, features, and precision applications	Electronic sensors detect the water level and control the refill solenoid — more accurate, with adjustable set points and safety cut-offs.

Choosing the Right System

Consider the size of your pool, pond or tank, whether mains power is available nearby, and how precise the level needs to be. Float systems are the low-maintenance choice for most residential pools, while electronic controllers suit ornamental fountains, koi ponds and applications where a narrow water level tolerance is important. Not sure which suits your setup? Contact the Aqua Clear team for advice — we'll help you match the right controller to your pump and plumbing.

Installation Tips

Install during construction where possible — retrofitting is easy, but a built-in install gives the cleanest result.
Position the controller away from skimmers and returns so it reads true water level, not surface movement.
Use a filter or strainer on the fill line to prevent debris jamming the valve.
Check and clean floats or sensors as part of your regular pool or pond maintenance routine.

Water Level Control — Frequently Asked Questions

What is a water level controller?

A water level controller is a device that automatically maintains water at a set level by topping up evaporation losses in a pool, pond, fountain or tank. It uses a float mechanism or electronic sensor to open a refill valve when the level drops and close it when the target level is reached.

Do water level controllers need electricity?

Manual float-style controllers are fully mechanical and require no power. Electronic water level controllers need a low-voltage power supply for the sensors and solenoid valve.

Can I add a water level controller to an existing pool?

Yes. Retro-fit controllers are available for existing pools, ponds and tanks, and can usually be installed in a single visit by connecting to your existing fill line or a nearby garden tap.

How much water does a pool lose to evaporation?

In Australian summer conditions, a swimming pool can lose around 5–8 mm of water per day through evaporation — up to several thousand litres per year. An automatic level controller quietly replaces that loss without you lifting a finger.

Which is better: a float valve or an electronic water level controller?

For most residential pools and ponds, a manual float valve is the simplest and most reliable choice — it needs no power and has very few moving parts. Choose an electronic controller when you need precise level control, such as for ornamental fountains, koi ponds or tanks with narrow tolerances, or where you want adjustable set points and safety cut-offs.

How often does a water level controller need maintenance?

Very little. Inspect the float or sensor and clean the fill-line strainer every few months as part of your normal pool or pond maintenance. In hard-water areas, descaling the valve occasionally will keep it operating smoothly for years.
