 i have just bought this pump and i do not no which is the in let and which is the out let there is a mark on one of the hose ports like an arrow pointing to your right if holding it i am new to all this wfp stuff but been a trad for 10 years now but as i am getting older now trying to make things a bit easier now ps the instructions do not tell me which is which

I would imagine as you look at the pump facing you the inlet will be the one on the left?

Dont quote me

look at the bottom of pump and a arrow will show you the way the water flows

If the hose connections are at the bottom of the pump then the left side is inlet and right is the outlet (looking at it from the front).
