How do I maintain my water feature?
Freezing conditions can cause serious damage to water features, in particular to the electric pumps. For this reason, it is important that water features are properly prepared for the onset of severe winter weather. Although many water features are frost resistant, they still require protection from freezing water. Ideally, water should be drained off before winter every year and not replaced until spring when any risk of hard frost has passed.
If you are unable to fully drain down a fountain, other measures must be taken to ensure water does not freeze solid in the bowl. For example, during mild periods of frost, a tennis ball placed in a fountain bowl will gently agitate the water to prevent it from freezing. This is particularly important for pool surrounds, wall, bowl and trough fountains.
Alternatively, smaller fountains can be emptied using a sponge before covering to prevent them filling with rainwater. The winter is also the ideal time to dismantle the pump for a thorough clean and any limescale should be scrubbed off using a mild, non-toxic detergent, paying particular attention to the impeller/rotor.
