View Full Version : Plastic Pipe

Just wondering if one of you who knows why at one store schedual 40 pipe is any where from $.40 to $.75 cheaper.
All of them are from different manufactures, but have the same psi rating and temp ratings. The guys at the irrigation houses tell me it has to do with the amount of virgin plastic being use.

Use the cheaper pipe. If the rating is above the pressures you are intending to run, you won't have a problem.

That the point of my post. If it has the same or eceeds ratings, why is their such a price difference.
Of course I use the cheaper priced pipe.

The virgin to regrind ratio in plastics will not degrade the density of the material in any appreciable amount. However, if the regrind being used for the pipe is of a lower density then you would have some degradation of the pipe.
The price differential is probably due to the volume purchasing of the materials + variations in markup prices.

Never thought about the density of the pipe.
The irrigation places I guess figured that your not going to go to a differnt store just to buy pipe. The only reason I do this is that the place I buy pipe is only 6 blocks away from where I live. I can save anywhere from $10 to $50 doing it this way. It's a rare instance that I go to Orchard Supply Hardware just for pipe.
