The Trevoli PT series pressure expansion tanks are designed for residential, light commercial, and irrigation applications. The tanks are constructed of a polypropylene liner combined with high grade butyl diaphragm to insulate water and air. This provides a closed system for drinking water preventing the growth of bacteria and vermin intrusion. The cast stainless steel water connection is designed for corrosion resistance. All tanks are tested to ensure the best quality.
