The Trevoli PT18 18-Litre Vertical Pressure Tank is engineered to deliver reliable water pressure, reduce pump cycling, and extend the life of your water pump system.


The PT18 features a proven single-diaphragm design with a premium FDA-approved butyl rubber diaphragm that separates water from the air chamber, helping maintain water quality while reducing wear.


Built for durability, it features a patented stainless steel water connection, a tough appliance-quality outdoor finish, and is factory pre-charged to 58 PSI (4 Bar) with nitrogen to improve diaphragm life, reduce corrosion, and maintain consistent performance.


Available in a vertical configuration only.
