(Always check your local building codes to see what's approved for your application and area.) This article presents both sides of the PEX plastic fittings vs. brass debate. Common problems encountered with PEX brass fittings include leaking due to improper connections and corrosion leading to poor-quality water. For concrete slabs, pressure is maintained at 30 psi during the pour and is monitored to assure integrity of the system.
