Frequently asked questions
Can the Varipump be used with Nexus and EazyPod automatics?
Yes, the Varipump is ideal for using with either the Nexus or EazyPod automatics.
Does the Varipump come supplied with a plug?
No, Varipump adheres to UK pond equipment laws, and requires that it is wired into a safe, compliant, outdoor electrical system, ideally with an RCD cut-off. If you are unsure, consult a qualified electrician.
What size fuse do I need?
As all the Varipumps use less than 700watts so 3 amp fuse is suitable.
How long is the power cable?
The cable from the mains to the control box is 2metres, the cable from the control box to the pump is 10metres, this makes the total length 12metres.
Can the control box be kept outside?
The control box is weather/rain proof and can be kept outside, it MUST NOT be submerged in water.
Can the Varipump be used as a dry pump?
Yes, the Varipump is suitable to use as a dry pump on a gravity fed system, the pump is not self-priming so a non-return valve needs to be used if the water level is below the pump.
If I am using rigid pipework what fittings are required the plumb the Varipump in?
You will need two unions the plumb the Varipump to rigid pipework, the Varipump 10000 takes 1½" threaded fittings and the 20000 and 30000 both require 2". Buy the Single Union Threaded Female to Plain Female

Step 5: Pull the impeller out of the housing by hand
Step 6: Clean the impeller with a bush. Handle carefully to avoid damage
Step 7: Clean inside the impeller housing with a brush Step 8: Replace the screws and inlet strainer basket
My Varipump has no flow?
Check the pump is wired correctly, the fuse has not blown and the pump his switched on at the controller.
If using the pump dry, make sure it is primed.
Ensure any valves in the pipework are open.
If using a non-return valve verify the orientation is correct.
