Plumbing Requirements & Tips
When purchasing plumbing supplies first make sure that everything is rated for pressure, it should be labeled as Schedule 40 on every plumbing piece. If it is labelled DWV it is for drainage only and will not be able to handle the pressure you need for your NSP to have proper water circulation. We personally like SPEARS and Bluefin brands for Sch. 40 plumbing supplies.
