Safety and Warranty Information

General Guidance

In this Warranty and Safety Information, “you” means the customer and “Hero Labs” means Hero Labs Sp. z. o. o.

This product is designed to aid in the detection of water leaks in conventional potable water systems installed in line with the prevailing European and British Standards Codes of Practice. It should not be used for any other purpose, or as a substitute for regular inspection and maintenance of the system in which it is installed. It should only be used in good order and good condition, in adherence with the operating instructions and this guidance. In addition to and separate to this guidance, best health and safety practices, legislation and regulations should always be followed. No liability is assumed by Hero Labs for any damage owing to non-compliance with the instructions and guidance provided (for the avoidance of doubt, nothing in this Warranty and Safety Information excludes or limits liability for death or personal injury resulting from negligence). Modifying the device in any way, or using spare parts or accessories not supplied by Hero Labs, will result in voiding the warranty and the CE marking, and could even result in injury. 

Installation Guidance

Installing this product involves making material changes to the potable water system of your property. It should only be installed by a trained and accredited plumbing professional. It is strongly recommended that your appointed installer reads all of the enclosed documentation before commencing the installation. Installers should verify that there is enough space for the Sonic unit before making material changes to the water system. The water supply must be isolated and as much water drained from the system as possible prior to installation. Installers should check for leaks after completing the installation. All parts supplied by Hero Labs that are intended for use in contact with potable water are WRAS BS 6920 accredited (or equivalent). Where third-party materials are used in contact with potable water (such as sealants or PTFE tape) they must be WRAS BS 6920 accredited (or equivalent). The installer is responsible for ensuring that any materials they use are compliant with the relevant British or European Standards.

Sonic should be installed on the main potable water supply pipe for the property, immediately downstream of the property’s existing potable water shut-off valve. Where multiple entities share a potable water supply pipe, such as multiple tenants of a single property, or neighbours sharing a potable water supply pipe, you must obtain the approval of such other entities before installing this product. Similarly, if you do not own the property, you must obtain the owner’s permission to make the material changes required to install this product. 

Sonic is capable of shutting off the incoming water supply to the property. Therefore, it MUST NOT BE INSTALLED UPSTREAM OF FIRE SUPPRESSION SPRINKLER SYSTEMS, or any safety system that relies on the supply of water. There must be a branching of the supply line upstream of Sonic to supply sprinklers or any other critical system in order to ensure their uninterrupted operation in an emergency. 

Further information is provided in the Installation Guide for Plumbing Professionals. In addition to and separate to these instructions, best practices for safety should always be observed.  

Power and Radio Emissions Guidance

Sonic has the option to operate from mains power (~240VAC) via the included power supply. As with any mains appliance, care should be taken to avoid mains cables becoming frayed or damaged. In the event that any mains cable becomes damaged in any way you should immediately stop using the device and contact Hero Labs for a replacement cable. The included power supply is designed to be used with a conventional switched wall outlet – i.e., it should always be possible to switch the power supply on or off independently. The power supply is intended for indoor use only, and only the included power supply should be used to power Sonic from the mains. When servicing Sonic or making any change to the water system Sonic should always be turned off at the outlet (if powered by mains), and ideally unplugged, to avoid the dangers associated with water and electricity. 

Sonic contains a wireless radio that broadcasts information. This radio has been tested to ensure compliance with the EU Radio Equipment Directive (2014) and the UK Radio Equipment Regulations 2017 with respect to safety, electromagnetic compatibility and efficient use of the radio spectrum. 

Sonic is designed to work with a companion app, available in the Apple App Store and Google Play Store. In order to ensure full functionality, Sonic, the Signal hub, and a compatible smartphone with the companion app installed should remain connected to the internet at all times. The companion app should be regularly updated to the latest version as updates are released. Use of the companion app is subject to Hero Labs’ Privacy Policy.


Sonic is designed for use with AA Lithium Batteries only.

Warning, replacement of a battery with an incorrect type can potentially defeat a safeguard (for example Sonic is not designed for use with any rechargeable battery types).

Disposal of AA Lithium Batteries into fire or a hot oven, or mechanically crushing or cutting of a battery, can result in an explosion.

Leaving a AA Lithium Battery in an extremely high temperature environment can result in an explosion or the leakage of flammable liquid or gas.

AA Lithium Batteries subjected to extremely low air pressure may result in an explosion or the leakage of flammable liquid or gas.

Limited Warranty

Hero Labs warrants this product to be free of defects in materials and workmanship for a period of two years from the date of purchase by the original purchaser-owner. Hero Labs will repair or replace defective products at our own expense. Repair or replacement may be performed by an authorised third party of Hero Labs’ choosing. If the product is no longer available at the time of a warranty claim, Hero Labs reserves the right to replace it with one of equal or greater value, or refund the original purchase amount (at our sole discretion). 

To submit a warranty claim, the original purchaser-owner should submit the following information to

  • Product name or model number
  • Proof of purchase including the date of purchase, such as an invoice or receipt 
  • Proof of installation by a trained, accredited professional
  • A description of the problem with supporting documentation such as photographs or videos.

If proof of the date of purchase cannot be supplied, the warranty period will be considered to have started from the date of manufacture. 

This warranty applies only if the product was professionally installed by a trained and accredited plumber, operated and maintained in accordance with these instructions, guidance, and the relevant British and European Standards and health and safety legislation and regulations. It does not apply to second-hand products, ex-display products, to any consumable part of products (such as seals or batteries); to products damaged due to environmental influences such as exposure to chemicals, limescale, excessive temperature or humidity, storm, flood or frost, or power spikes; or due to unreasonable usage or negligence by you or anyone other than Hero Labs. Normal wear and tear is not covered by the warranty.

This warranty will be voided if you modify the product in any way using spare parts or accessories other than those supplied or approved by Hero Labs.

This warranty replaces all other warranties and you agree that no other warranty, express or implied, or representation may be relied upon by you. Save for a valid warranty claim as set out above, Hero Labs will not be responsible for any loss, damage, expense or incidental or consequential damage of any kind, including but not limited to alleged liability under warranty, contract, negligence or other tort, arising in connection with the sale, installation, use or repair of any products or parts (save that nothing in this Warranty and Safety Information excludes or limits liability for fraudulent misrepresentation, or death or personal injury resulting from negligence). Hero Labs’ liability will not exceed the contract price paid for the product claimed to be defective.
