7. MAINTENANCE & CLEANING
Annual Maintenance
Following as for routine and impeller maintenance, once a year you should
service your pump by using Blagdon Pond Pump Cleaner. This may need to
be done more frequently in hard water areas or with harsh use.
Dismantle the pump and examine all parts for wear or damage, replacing any
parts that show obvious wear and/or damage. (See "Getting to Know Your
Pump" for parts/description and replacement codes).
Particular care should be taken to examine the cable entry point and the cable.
If there are any signs of damage the pump should be discarded.
Cleaning
The use of Blagdon Pond Pump Cleaner will give improved performance and
pump life by removing built-up lime scale and waste.
Use before dismantling for easier and cleaner handling.
Routine Maintenance
