Spare Tube for PH and EC Kontrol – Replacement Hose for Dosing Pumps

The Spare Tube for PH and EC Kontrol is the essential component to bring your automated dosing system back to life, ensuring precise nutrient management without leaks or errors. Designed specifically for Kontrol pumps, this replacement part guarantees that your measuring and dosing equipment continues to function with the precision of a Swiss watch.

Is your dosing pump losing pressure or leaking liquid?

Have you noticed that your pH or EC controller is no longer dosing the amount it should, or worse, have you found small puddles of nutrient solution or acid near the pump? These are the classic symptoms of a worn-out peristaltic tube. Over time, friction and aggressive chemicals (like pH Down) degrade the rubber, causing cracks, loss of elasticity, and eventually, rupture.

Ignoring this small maintenance detail can lead to a disaster in your grow room. A broken tube not only creates a mess on the floor but stops the automatic regulation of your water. The result? Drastic pH fluctuations or a lack of nutrients that can stress your plants, burn their roots, or ruin the harvest you've worked so hard for in a matter of hours.

The solution is quick, cheap, and simple: replace that old rubber with this original Spare Tube for PH and EC Kontrol. It is the exact replacement you need to restore the tightness and suction power of your pump, ensuring that your automation system works for you, not against you.

Reliability for your automated irrigation system

In high-performance crops, especially when using hydroponic and aeroponic systems, stability is everything. This spare tube is the heart of your dosing pump. By renewing it, you ensure that every drop of fertilizer or pH corrector is delivered with millimetric precision.

You won't have to worry about manually checking the tank every two hours. By keeping your equipment in top shape with quality spares, you regain the freedom to focus on other aspects of the grow, knowing that the chemistry of your water is under strict control.

How to replace the tube in your Kontrol meter

Changing the tube is a maintenance task that takes less than 5 minutes. You don't need to be an engineer, just follow these steps to do it safely:

1. Safety first: Disconnect the controller from the electrical current to avoid accidents.
2. Open the head: Remove the transparent plastic cover protecting the pump head (the rotating part).
3. Remove the old tube: Disconnect the input and output tubes (rigid ones) and carefully pull the worn rubber tube out of the guide.
4. Clean the area: If there was a leak, clean any salt or liquid residue from the rollers and the casing.
5. Install the new spare: Place the new tube following the curve of the rollers. Make sure it is not twisted.
6. Connect and test: Reconnect the rigid tubes, put the cover back on, and plug it in. Do a quick test to ensure it sucks and doses correctly.

Key advantages and benefits of this spare part

• High chemical resistance: Made of specific materials to withstand acids and concentrated fertilizers, which means a longer useful life and fewer changes.
• Perfect fit: Being an original spare, it fits perfectly into the Kontrol pump head, preventing air intake or fluid leaks.
• Restored precision: Recover the exact flow rate of the pump, ensuring that your humidity controller and nutrient dosers work with the data you programmed.
• Preventive economy: Changing the tube in time is much cheaper than repairing a pump damaged by liquid leaks inside the motor.
• Flexibility: The material maintains its elasticity for longer, allowing the rollers to slide smoothly without forcing the motor.

Care and maintenance

To extend the life of your new tube, we recommend keeping the pump rollers clean. Occasionally, you can apply a tiny amount of silicone grease to the tube (if the manufacturer allows it) to reduce friction. Also, try not to let the chemical containers run dry, as pumping air can dry out the tubes faster.

It is ideal to check the condition of the tube before starting each new crop cycle. If you see micro-cracks or if the tube has lost its round shape and looks flattened, it is time to replace it before it fails.

Frequently Asked Questions

How often should I change the tube?

It depends on the intensity of use and the aggressiveness of the products (pH Down is very corrosive). However, as a general rule, it is recommended to change it every 6 months or at the beginning of each crop to ensure maximum reliability.

Is it compatible with both pH and EC pumps?

Yes, generally Kontrol dosing pumps use the same type of peristaltic head for both pH regulation and fertilizer dosing (EC), so this tube is valid for both functions.

Why does the tube turn white or opaque?

This is normal due to contact with salts and acids. However, if it becomes stiff or brittle, it is a sign that the material has degraded and you need to install this spare immediately.

Personal Experience of Pevgrow’s CEO (Alan)

I'll be honest with you: there is nothing more frustrating than entering the grow room and finding a puddle on the floor because a 10-euro rubber tube decided to break. I learned this the hard way years ago. Since then, I consider this spare part as important as the fertilizers themselves.

My advice is that you always have one of these tubes in your toolbox. You don't wait for a light bulb to burn out to buy another one, right? Well, the same applies here. Having a spare tube for your Kontrol allows you to solve a breakdown in minutes and sleep peacefully, knowing that your plants will continue to eat and drink exactly what they need.
