connect water pump to irrigation pipe

[shaft1]

i'm trying to connect this pump
https://uk.rs-online.com/web/p/water-pumps/0266597/

to this irrigation pipe
https://www.waterirrigation.co.uk/c...rosure-15m-x-13mm-supply-hose/category/14130/

The inlet/outlet on the pump is 22mm. that's the external diameter and the irrigation pipe has internal diameter of 13mm.

can anyone point me to suitable connectors please?

Even if somebody does I advise you not to do it.

sounds ominous... why not?

The pump has been designed for 22mm inlet and outlets to change anything will put extra strain on the pump.

it's only a cheap pump from ebay so i'm not too bothered if it goes.

anyway i managed to connect the irrigation pipe to it using 22mm to 15mm straight coupling pushfit connector.
