Dear friends

I have a question.

In which NFPA standard it is recommended Material for Underground piping which is connected to Hydrant?

Is it possible to use Polyethylen instead of GRP for underground fire fighting lines?

Thanks for your help.

You can use RTR ( Reinforced Thermosetting Resin ) Pipes as underground Fire Water Line. It requires concrete thrust block at every sharp bend ( 90 deg, 45 deg)
