Just wondering what sort of pipe can be used for agi drains? I always thought it was the black bendy stuff. We moved a few of the rocks to check out our new agi drains that were put in the other day and its just a pale purple coloured pvc pipe. We looked at the 20 or 30cm coming into the silt pit and couldn't feel or see any slots in it. Would it just be slotted further along or has the plumber done something shifty?
Cheers
