Thread: pressure pump question please

Hi guys.
Our place had a spare pressure pump setup on the house tanks . Think they use to use it for a second set of tanks when the house tanks ran out anyway l wanna use it on the cabin we're doing.
l didn't take any notice of how the inlet and outlet pipes fitted when l took it off- silly bugar , so l dunno which is which . Hasn't got anything written on it .
So which one goes in and which one goes out ?
lt's a Davey 350 P , has the bubble thing on the top of the pump with a pipe connection , then it has another one at the bottom comming out from the front of the motor section .
l'd put in a pic but the cam's playing up .

Thanks for that.
Cheers.

PS , Forgot , l have a second even sillier question . What do you do when you first fire them up , don't you have to put air in them or something . l have a pump and pressure gage and stuff . l know , l wish it had a manual to but it doesn't . 2nd bugar !
