Annual Maintenance
Following as for routine and monthly 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).
Dismantle 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 parts codes.) Particular care
should be taken to examine the cable entry point and the cable; if there is any
sign of damage the pump should be discarded. On models 1500, 2500, 3250
and 4000 also check ‘O’ ring seal (see diagram below)
Winter Storage
The pump can be run in the pond during the winter but care should be taken
to ensure that it is fully immersed and cannot freeze solid. If the pump is not
used during the winter, follow annual maintenance procedure and store frost-
free in the house or garage until spring.
