. Thanks for the reply crusemm. I found the same forum link but was curious as to why its okay for irrigation where they are pumping higher psi. Buried in the ground. SDR is just an acronym "standard dimension ratio". meaning ratio of pipe diameter to wall thickness of the pipe. its the 26 that matters and I agree it is a bit thinner walled. Is sch 40 pipe "code"?According to this forum SDR is thinner than sch 40, and would not be an acceptable substitute.
Sch 40 has a pretty high pressure rating 180 psi, I think.
I am not sure just how high the irrigation piping is rated......do you know?.
Long story short, will you save hundreds? Probably far less and Probably not worth it in the long run. Pipes thinner than sched 40 break more easily if they are not properly supported when they are buried or the concrete decking shifts. Unless it was really big savons, I would stay with sched 40.
Schd 40 is the only way. Theres lots of cheaper pipe and it's used all over. They pipe pools with poly sprinkler flex line. Why chance it. Do you ever wanna dig up a busted line or deal with plumbing issues down the road over 200 bucks? Idk if you have suppliers near you nut 20ft sticks are cheaper than big box 10ft pieces and less couplings. You can use bell end pipe and save on fittings and cost there
I have run in to a few of those. What were they thinking? Had one that had poly hose, barbed adapters, and hose clamps. Spent weeks locating and repairing all the underground leaking joints. Jackhammmering up sections of deck, hand-digging to reach pipes. Plugged main drain. Nightmare. Definitely do it right the first time, because you do not want that repair bill. And it had no warranty because it still had all that poly, now glued to barbs instead of sealed with lumps of rust that used to be hose clamps. Apartment complex didn't have the budget to replace the pipes.pipe pools with poly sprinkler flex line.
I'm in Canada. Trying to place an order with Canpipe tomorrow.Supply houses are all open so are the big box stores. What's your zip code I'll find you somewhere to buy it
