What's the proper clamping method for poly pipe fittings? Double clamp??
We use poly pipe around here because of winter freeze. I'm going to use those Murray clamps that use a crimping tool to tighten, (as opposed to the screw clamps you tighten with a srewdriver). Anyway, someone told me I should double clamp, ie. use 6 clamps on a tee, not three. Wise advice or overkill?
