Is your water level dropping mysteriously, or are you tired of unrolling the garden hose every week? Kona Labs offers a wireless automatic filling and leak detection solution. Here is my full analysis to determine if this investment is really worth it for your pool.
The Quick Verdict
In a rush? Here are the key takeaways about the Kona Labs ecosystem (specifically the LevelSmart):
- The end of the hose chore: The system automates pool filling 100%. It's the ideal solution for vacation homes or frequent travelers who worry about their pump running dry.
- Trenchless installation: This is its biggest asset. Unlike traditional systems, you don't need to tear up your concrete deck. The sensor is wireless and simply sticks inside the skimmer or on the wall.
- A luxury with a price tag: It's a pricey piece of tech (several hundred dollars) compared to a simple $50 mechanical regulator. The investment is justified by the aesthetics and the protection of expensive equipment (pumps, liners).
Overall Rating: 4.2/5 (Excellent hardware, but customer support and price cost it a few points).
Technical Analysis: How does it actually work?
To understand if Kona Labs is right for you, we need to look under the hood. Kona Labs stands out with two flagship products: the LevelSmart (automatic filling) and the MeterDog (leak detection). Let's focus on the LevelSmart, their best-seller.
The "Retrofit" Challenge
The major problem with existing pools is that if no fill line was planned during construction, adding an automatic system usually implies breaking up the pool deck to run pipes. Kona Labs bypasses this problem with proprietary wireless communication.
The 3 Components of the LevelSmart System
The Wireless Sensor:
It's a small waterproof box that attaches directly inside the skimmer or on the tile line (above the desired level). It doesn't use a mechanical float that can get stuck. It uses capacitive or water contact detection technology. It is battery-powered and communicates via radio frequency (not Wi-Fi, which is crucial for range) with the controller.The Valve Controller:
This is the brain of the system. It plugs into a standard outlet near your pool pump. It receives signals from the sensor. If the sensor tells it "I've been dry for 30 minutes" (to avoid triggering due to waves), the controller activates the valve.The Solenoid Valve:
This is the plumbing part. It installs on a water supply line (like an outdoor faucet or an irrigation line) and connects to the pool's return pipe. When the controller gives the order, the valve opens, water flows into the filtration circuit, and fills the pool.
"Wake-up" Technology
To save sensor battery, the system does not communicate continuously. It "wakes up" at regular intervals to check the level. This allows the sensor to last several years without a battery change, a technical point often overlooked but essential for user experience.
The Pros: Why it appeals
After analyzing user feedback and technical specifications, here are the real advantages of the system.
1. Preserved Aesthetics (The "Invisible" Factor)
This is the number one argument. If you have a designer pool with a beautiful travertine or wood deck, you don't want a garden hose crossing the yard, nor a mechanical "inverted bottle" type regulator floating visibly at the water's edge. The LevelSmart sensor hides in the skimmer. Once installed, the system is totally invisible.
2. Active Equipment Protection
We often talk about comfort, but it's also insurance. If the water level drops below the skimmer (high evaporation in summer or a small leak), the filtration pump sucks in air. Result: it loses prime, overheats, and can burn out. The cost of a new pump ($500 to $1,000+) often justifies the purchase of the LevelSmart. For vacation home owners, it's absolute peace of mind.
3. Do It Yourself (DIY) Installation
You don't need to be a hydraulic engineer. If you know how to cut a PVC pipe and glue a fitting, you can install it.
- Pool Side: Zero tools. You stick the sensor on.
- Equipment Pad Side: You cut the water supply, insert the valve, and plug it in.
Pairing between the sensor and valve is generally pre-configured or done by pressing a button.
4. Radio Connection Reliability
Unlike Wi-Fi gadgets that drop connection as soon as they are 30 feet from the house or underwater, Kona Labs uses a specific radio frequency for Sensor <-> Valve communication. This allows for a much superior range (often advertised up to 1,000 feet in open field, realistically 150-300 feet with walls). This is crucial because the equipment pad is often far from the pool.
Limitations and Drawbacks
Here is where we speak frankly. No product is perfect, and Kona Labs has constraints you need to know before pulling out the credit card.
1. A High Price for a Single Function
The LevelSmart system is expensive (often between $500 and $800 depending on retailers and versions).
- The critique: In the end, it's a device that just opens a faucet.
- The reality: You are paying for the patented wireless technology and miniaturization. If you have a tight budget, this is a major hurdle. A basic mechanical system costs 10 times less.
2. Customer Support Sometimes "Ghosting"
Analyzing verified reviews over several years (Trustpilot, specialized forums), a pain point comes up: customer service. Although the hardware is reliable, in case of failure or a specific technical question, users sometimes report difficulties reaching Kona Labs support quickly. in the world of "Premium Service," one would expect immediate responsiveness, which isn't always the case.
3. Dependence on Batteries and Electronics
Even if the battery life is good, the sensor will eventually need a new battery. If you forget to change it and leave for 3 months, the system stops filling. Furthermore, like any connected object, electronics can suffer from the aggressive environment of a pool equipment room (humidity, chlorine fumes, heat). It is less robust than a purely mechanical plastic float that will last 20 years.
4. Possible False Positives (The "Wave" Effect)
Although the software smooths the data, a very agitated swimming session (cannonballs into the pool, kids playing) can temporarily confuse the sensor. The system is designed not to react immediately, but it is advisable to turn it off if you plan a giant pool party to prevent it from trying to fill while the water is moving in all directions.
Alternatives and Comparison
To be objective, let's look at what exists elsewhere.
1. The "Low Tech" Alternative: The Mechanical Regulator (e.g., Rola-Chem)
- What is it? A box placed on the coping with a float, connected to a garden hose.
- Pros: Dirt cheap ($50-$100), zero electronic failure, 2-minute installation.
- Cons: Very ugly (a hose crosses the deck), tripping hazard, must be removed during swimming.
- Verdict: For an above-ground pool or if aesthetics don't matter to you.
2. The "Integrated" Alternative: Pentair or Jandy (Zodiac)
- What is it? Wired filling systems connected to complete automation hubs.
- Pros: Total integration with the pool management app, wired power (no batteries).
- Cons: Often requires heavy construction (trenches) to run cables and pipes to the pool. Overall cost often higher if labor is included.
- Verdict: To be preferred only if you are building your pool or doing a major renovation.
3. For Leak Detection: Flume Water Monitor
If your goal isn't filling but just knowing if your pool is leaking:
- Flume attaches to your main water meter. It can detect if your autofill (even mechanical) is running non-stop, a sign of a leak. It's an excellent complement to Kona Labs, but it doesn't replace the filling function.
Installation and Daily Use
If you decide on the LevelSmart, here is what to expect during setup.
The Critical Step: Plumbing
This is often the scary part. You must identify a pressurized water source.
- Tip: Many people tap into the irrigation system if it's close to the pool equipment.
- You will have to cut the pool return pipe (after the filter) to insert an injection "T".
- Make sure to install a backflow preventer (often not included but essential) to prevent pool water from flowing back into your drinking water supply (this is a legal requirement in many US states).
The Easy Step: The Sensor
Clean the skimmer surface well. The provided epoxy adhesive is powerful. Once stuck, it's done.
- Expert Tip: Place the sensor in a spot where it won't hinder the removal of the skimmer basket for cleaning. It seems obvious, but it's the #1 rookie mistake!
Price and Savings Tip
The LevelSmart system represents an investment. Prices fluctuate, but generally count on a significant budget for the complete kit (Valve + Controller + Sensor).
However, there are ways to optimize the bill. Kona Labs sometimes offers direct deals.
Savings Tip:
If you have a large cart (for example, if you equip the house with a MeterDog in addition to the LevelSmart), use the code ANTHONYMA10.
- The benefit: It offers a $50 discount for orders over $500.
- It's not negligible and often covers shipping costs or part of the plumbing accessories needed for installation.
Frequently Asked Questions
The system uses a waterproof wireless sensor placed in the skimmer that communicates via radio frequency with a valve controller. This allows the water level to be adjusted automatically without having to dig trenches or run electrical cables to the pool.
Yes, the LevelSmart sensor is designed with corrosion-resistant materials to withstand aggressive chemical environments, whether salt water, chlorinated, or brominated. The absence of moving metal parts in direct contact limits premature wear.
Unlike Wi-Fi, Kona Labs' proprietary radio technology offers a theoretical range of up to 1,000 feet (300 meters). In practice, it effectively passes through concrete walls and the ground, ensuring a reliable link even if your equipment pad is located 150-300 feet from the pool.
Absolutely, installing a backflow preventer is essential and often legally mandatory. It prevents pool water, potentially loaded with chemicals, from flowing back and contaminating your domestic drinking water supply.
The controller has a built-in fail-safe: if it does not receive a signal from the sensor for a given period, it prevents the valve from opening. This avoids any risk of overflow or unwanted filling in the event of battery failure.
For a spa, the installation is identical to a standard pool. For an infinity pool, the sensor must be placed imperatively in the catch basin/surge tank (and not the main pool) to correctly regulate the overall water volume of the system.
Thanks to its intermittent "wake-up" technology, the sensor battery offers an autonomy of several years. The system does not communicate continuously, which preserves energy while ensuring regular monitoring of the water level.
Yes, you can use the code ANTHONYMA10 during your order. It allows you to get an immediate $50 discount for any purchase over $500, which is ideal for covering part of the initial investment.
