Replace your SPV4 pump with ease
Spare diaphragm pump for C and L Series C12 & C24 controllers 2015 model onwards. This is now the standard pump and replaces IRR-SPV2.
Before using the pump for the 1st time it needs to be primed by squirting water through the inlet (marked I) using the syringe provided in the main kit with a short piece of tube attached.
The pump is relatively easy to replace, just follow the video instructions below. The only part to pay particular attention to is the order in which you replace the foam dampening sleeves, as one of them is specific to the nozzle side of the SPV Pump.
