• Can I exceed the recommended pre-charge pressure on my VAREM vessel?

  Do not exceed 3.5 bar of pre-charge pressure unless authorized by Varem S.p.a.

• What should I do if my VAREM pump controller shows a dry running alarm?

  The system will automatically make 3 attempts to restart. If it fails, check the pump suction to ensure proper water supply.

• How do I handle water leaking from the air valve on a VAREM tank?

  If water escapes from the air valve, the vessel must be completely replaced as this indicates a punctured membrane and internal corrosion.

• Are VAREM products suitable for drinking water?

  Yes, VAREM products with the appropriate hygiene symbols (such as ACS, WRAS, NSF61) are certified for use with drinking water. Ensure an initial rinsing process is completed before use.
