Using PVC pipe and their matching T's there is no need of tiewraps. A couple
of hose clamps just above the T will hold them in place.

ZR and HAROLD, I have been having issues with the tie wraps breaking in the
AZ sun. I suspect the UV is getting to them badly. The metal ones don't
break, but I can't use those for shunt feeding, of course. Can you
recommend a source for ones that don't break? It is a real pain replacing
them every year or two...... He he he
