Vent Pipe in Loft from Open Vented System

[wildhorses]

To put a bigger trap door into the loft I've moved my F&E and Cold Water storage to the other side of the trap door, all moved and piped but wanted to check as long as the highest point of each vent is 450mm above each tank does it matter on the angle / routing.

Probably draft question but does pipework in a series of angles rather than curves make any difference for the vent, all the diagrams I've seen show a vent curved over where mine now goes up then over at 45 degrees then drops down to the tank in both cases, is that ok?

thanks

should be ok, you just added slight angle on the pipe, didn't you?

Won't matter what angles & bends you put on a vent just as long as you keep it rising to its highest point & dropping to the tank - ie :- no parts where water can trap air.
Make sure each vent is proper height & doesn't go too low & in below the water.
