Alkathene+PVC - 05/25/03 02:43 AM
Over here, I've just done few rural jobs with customers having already run sub-mains to out-buildings, before I get there.
And they generally just want then hooked up at each end, so to speak.
But, this is sort of got me worried, because 9 times out of 10, the underground cable(normally 2.5 or 4.0mm 2C+E)is run through a length of black alkathene water pipe(it's used for irrigation systems on farms)and buried and the trench back-filled.
What worries me is that, some where I heard that alkathene is known to react with the chemical composition of PVC.
In some cases I have even asked that the cable be dug up and run in PVC conduit and this does not normally go down too well!.
Have any of you guys ever heard of this chemical problem?.
