RE: Grooved Underground, Thrust Blocks Required?

unless you are connecting to a pipe, fitting or joint type that can come apart under increased pressure, lack of compaction or some type of movement, you don't need thrust blocks.

RE: Grooved Underground, Thrust Blocks Required?

Good luck with that! It's like trying to find a listing for ductile Iron Pipe above ground for fire protection. The most often listed reason not to use PVC (C900) above ground is it's not listed. Well try and find a DIP that's listed for Fire Above ground. Thom McMahon, SET Firetech, Inc. 2560

Bobby, you may want to look at that again, the DS-1 only allows you to use a 1CPVC x 1FM adapter by Tyco in wet systems, and suggests the use of Fig. 12 for wet systems, nowhere does it allow the use of a coupling. Wet or Dry. Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O. Box 882136
