Install the pump
Before installing, please read and follow all safety instructions
The fountain pump should be located on a firm and level base in the pond / water fountain. The pump should be covered with water at all times. Make sure that there is ample cable from the mains supply. Place the pump in the desired location; attach the hose connector that is suited to your water feature and connect to your fountain hose. You can soften the end of the hose by immersing in a bowl of hot water; this aids the push-fit to the pump outlet hosetail.
Tip: The larger 1″ hose fitting will give maximum performance when fitted to the pump.
The water flow can now be adjusted by turning the flow control valve – clockwise to increase flow, counter clockwise to decrease flow.
Connecting to hose
Select the hose diameter suitable for your fountain, 1” hose is recommended for maximum flow. Cut off any unneeded, smaller diameter section of the hosetail for best pump performance. See video for more information.
Use the shortest possible length of hose to minimise flow restrictions. Avoid folds and kinks, which reduce flow and performance.
Clean and maintain the pump
WARNING – Failure to carry out routine maintenance leaving the pump under reduced or no flow conditions (i.e. run dry or blocked prefilter) will result in a shorter pump life and may invalidate the guarantee.
Occasional maintenance
Switch off electricity.
Remove the pump from the fountain/feature or pond (do not use the cable to lift the pump).
Follow steps below: –
- Firmly pull the front and back filter cage from the motor body.
- Thoroughly wash both parts and motor section in fresh water.
- Remove yellow impellor cover by turning counter-clockwise to release lock.
- Then pull firmly away from pump motor.
- Remove impellor from the pump motor. Wash parts with fresh water carefully.
- Replace parts and return to fountain.
Annual Maintenance
Switch off electricity.
Remove the pump from the fountain/feature or pond.
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.
Store in winter
The pump can be run in the pond or feature 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.
Access/replace the impellor
Follow the steps for cleaning and maintaining. Remove the impellor from the pump and replace with a new one.

FAQ’s
Top FAQ’s
What does a fountain pump do?
A fountain pump is used to circulate water in a fountain feature, for either indoor or outdoor water features. This type of pump is used to create an attractive visual and audible effect.
A pond pump is used to circulate water around a pond for similar reasons to a fountain pump, but also adds the benefit of oxygenating the pond which is good for any pond life. It can also be used to circulate water to a jet nozzle, a filter, spitter, waterfall or spillway.
What is the difference between a fountain pump and an Auto Shut Off pump?
Both types of pumps are designed to run water fountains. However, the auto shut off feature prevents the pump running dry if the water level reduces, such as through splash or evaporation; which would break the pump motor. Sensors on the pump body detect low water levels and automatically switch the pump off to protect it from running dry. When the fountain is topped up with water, the sensors switch the pump back on.
Which size pump do I need?
To select the correct size Pennington Aquagarden fountain pump, please see the selection videos and select the pump information relevant to the height of your fountain or see the height selection diagrams on the product pages.
My pump has slowed down and isn’t running properly, has the auto shut off stopped working?
No, it is unlikely the auto shut off has stopped working. These pumps will continue to run at a safe level, for some time just before they shut off, however that can be a slower, noisier flow due to the pump sucking in air. Top up your fountain and you should get a normal flow.
Also, ensure that the pump is positioned flat and level for the sensors to work correctly.
Do I always need to have the pump running?
No. A fountain does not have to be run constantly. However, water can become stagnant if left still for a long period of time. If you run your pump continuously, remember to top up the water regularly.
What do I do with the pump in winter?
See ‘How to store in winter’
Why is my pump making a lot of noise?
Check and top up the fountain reservoir, if the water is low it can produce noise as it sucks in air.
Clean the pump cage to ensure good water flow (see ‘How to Clean and maintain the pump’).
Clean, (or replace if needed), the impellor (this is a spare replacement part). See parts diagram for spares part code.
Also, ensure that the pump is positioned flat and level for the sensors to work correctly.
Can I use a timer on my pump?
Yes, as long as all electrical safety procedures are maintained.
My pump has stopped running, what is wrong?
Check the pump has not stopped via the auto shut off feature, due to lack of water in the fountain. Top up reservoir to restart the pump.
Check the power supply is on.
Check fuses and wiring (see the instructions manual that came with your pump, or locate a copy on the support pages)
Ensure that the pump is fully submersed, and not sucking air due to lack of water in your feature.
Follow routine maintenance procedure (see ‘how to clean and maintain the pump’).
Ensure that the pipe work is not blocked, leaking or is laid so that it gets crushed or kinked.
Keep the height that water is to be pumped from the water surface (called head) to a minimum. The higher the head the lower the flow rate and the more wear on the pump.
Use the largest diameter, smoothest bore hose over the shortest distance and keep hose fittings to a minimum. This removes frictional loss of flow and so increases pump flow rates.
