Warranty reviews

Each Miltom tank is covered by a 5-year manufacturer’s warranty. A very important aspect of warranty protection is the annual review of the technical condition of the fire protection tank.
Inspection of the tank allows us to assess its technical condition, and thus carry out the necessary maintenance in a timely manner. An important element is also the training of those responsible for operating the tank on site. The overarching goal of inspections is to extend the life of the tank and comfort of use. After 3 years of operation, the tank is emptied and its interior thoroughly washed. Verification of the condition of the EPDM or PVC membrane is a priority to ensure that the tank will ensure safety for a long time.

Thanks to such actions, the technical condition of the product purchased by you will be monitored on an ongoing basis, which will ensure the functioning of the system in accordance with applicable regulations, but also the certainty that if necessary the system will work reliably, even 30 years after its initial installation. Documentation of each of the tanks we built is recorded in a database. Additionally, database backups are stored on secured servers. We also carry out technical inspections of fire tanks that are not from our distribution and help in servicing and maintaining their reliability. We dedicate an individual “Tank Log” to each tank, which contains all annotations about inspections and possible repairs that have been made. This approach ensures that all activities related to tank inspections will be carried out on time.

of technical condition

If you have any doubts regarding the technical condition of the fire tank, please contact us. We have a lot of possibilities related to the expertise of the technical condition of the tank. Our knowledge and over 25 years of experience will help in the selection of the best solutions and will present a very detailed report.


In connection with the recent information about the offer by some companies, inspection of the tank with a ROV type as a substitute for activities related to cleaning the inside of the tank performed during inspections, we would like to inform you that such practices are illegal and may cause irreparable damage. Regulations on the inspection of tanks after 3 and 5 years of use precisely recommend washing the inside of the tank to prevent possible breakdowns caused by contamination and sediment. Periodic inspections should not be replaced with an inspection with a ROV robot. We receive information that such services are offered along with the argument that it reduces the cost of operating the installation.

Please note that washing the inside of the tank maintains its efficiency and extends its service life, while drone inspection only provides information on its technical condition. Washing the inside of the tank at least once every 5 years is an absolute necessity, and the Drone is only a diagnostic tool and will not replace service activities or tank inspection.

If you have any questions regarding this issue, please do not hesitate to contact us and we will provide detailed information.
