Product Description

The Pressure Wave Pressure vessel is a perfect addition to a rainwater harvesting system. Storing water at pressure, a pressure vessel can help prevent pump chasing in the event of a dripping toilet valve. This can in turn reduce the amount of times the pump switches on and prolong pump lifespan.

The Pressure Wave™ Series is constructed of a virgin polypropylene liner combined with an FDA approved high grade butyl diaphragm. This is held against the wall of the tank with a steel clench ring. The brass air valve, sealed by a threaded o-ring valve cap, prevents air leaks. Water enters the tank through a patented stainless steel water connection.

The diaphragm and liner are both reinforced in specific wear areas for longer life. All internal parts including the air valve are rounded to prevent piercing of the diaphragm in extreme conditions. The water connection uniquely provides a dual water/air seal ensuring a complete leak free and maintenance free pressure vessel.
