I am located in SE NY state upstae from NYC (Hudson Valley)I have been informed by both a local contractor and a local pipe supplier that SDR 26 is just not used for gravity sewer here because they cannot get it, at least unless they buy a truckload, but then no one seems to want to use it even if they have it in stock as everyone seems to prefer the SDR 35--easier to work with, more readily avaialble, cheaper. The local sewer district prefers SDR 26, and specifies it, for uses under high traffic areas like roads and parking lots. They require Class 52 DIP for applications where cover is less than four feet, but prefer the SDR 26 for deeper installation in those areas I noted above. My question is if others in this part of the country have had a similar problem in getting SDR 26, and if they have found that the SDR 35 will perform as well as the SDR 26 when used as stated for under roads and parking areas--that is will hold up as well over time agaisnt collpasing.
