6. Maintenance

The GT tank is maintenance-free, but we recommend
checking the tank for damage two times a year.
If the tank is removed, when the tank
and /or the system is still pressurized,
make sure that the tank is without
pressure.
Close the isolating valves and remove the
precharge pressure through the air valve.

6.1 Maintenance schedule

• Check the precharge pressure annually.
• Before checking the pressure, make sure that
there is no water in the GT tank (switch off the
pump, and open a tap).
• If water escapes during the precharge pressure
check, the bladder is defective.
GT tank bladder with a volume larger than 80 litres
can be replaced.

6.2 Checking the GT tank for damage

During maintenance, check the following:
1. Is corrosion visible?
2. Are scratches, dents, etc. visible?
In case of serious damage, contact your nearest
Grundfos company.
