And cost...;)

I have frequently run funny pipe over 10 feet...however...it depends on what it is feeding....don't run that much funny pipe to a large rotor....but it will handle most anything at that length....but it costs so much more to do it!

the answer is both. But the reason to not use long lenghts of funny pipe is due to diameter and loss of flow.

People say that you can use either poly pipe or PVC with poly having more benefits. Then I also frequently read *not* to run funny pipe more than 2-3'. Isn't funny pipe made of poly? How is it that you can run poly pipe long distances but not funny pipe? I can only conclude that they are not the same - they must either be different diameters or different material or both?

Thanks,

Right, when i said i heat poly pipe, i didnt mean like i practically melt it, i just use a small amo9unt of fire from the blow torch, and quick pass over the pipe. Nothing will happen from what you did!

??One time I heated up some water in a microwave and poured in onto the poly pipe to insert a replacement piece-it worked well. That wasn't as much heat as a torch so probably didn't weaken pipe, right?

True!!!! All the contractors do it around here and i have been doing it, (quick heat) and it helps with the fitting, i have never actually had a problem with it

But i guess, anything is possible

Don't heat poly pipe! It weakens it and eventually may cause a leak

Do not heat pipe so it is easier to insert the fitting. I use a small amount of dish soap on the barbed part of the fitting to help it slide in.

PVC leading to the valves (schedule 40) because that can only hold constant pressure, and poly for downstream piping. Poly has really no disadvantages, but these are the advantages
- Can be pulled by a contractor, no damage or digging
- Is connected to fittings by clamp, no glues
- can be heated with blowtorch to soften, and that easily allows you to insert fittings
- flexible
- easy to cut, 1,2,3

Id use poly

PVC vs Poly

Where can I find information on the relative advantages and disadvantages of each? Poly seems like it would be easier to work with, but I assume there is a downside, too. Is it significant?
