Thread: water flow cross?

    water flow cross?

    I was told that the pipe fittings from the two inlets to the pump need to be perfectly or the pipes will cross and if that happens everything is shot .. can someone explain this to me im not really understanding this .. crossing factor .. I know all plumping should be set correctly .. IM just wondering what this crossing is .. I would assume that even if the connection was a bit off it would leak and get some air in it but .. "cross"? .. the water should still be sucked from the same pipe in the same direction .. but im not an expert

    Are they talking about crossing threads in the pipe joins?

    Cross threaded maybe ?

    yes - that is a bad thing - if you are using threaded pipe connections - make sure you are tightening them the correct direction.
