About This Product
The PressureWave tank is a premium-quality, industrial-strength pressurized well tank used by top pump companies and installers around the world. The water chamber is constructed of a virgin polypropylene liner and a FDA compliant, high-grade butyl diaphragm which does not impart any taste or odor to your drinking water and keeps the water contaminant-free. The O-ring-sealed air valve and cap and our stainless steel patented water connection ensure no air leakage. The corrosion-free, rugged composite base and rust-resistant exterior paint finish add to the tank's longevity. This is a maintenance-free, pre-charged pressure tank which is backed by a 5-year warranty and can be a direct replacement for most installations.
Highlights
- Contaminant-free water chamber
- WQA certified to NSF/ANSI/CAN 61 and 372 standards
- Maintenance-free
- Physical separation of air and water chambers for peak operating performance and improved efficiency
- Deep-drawn steel construction ensures structural integrity and pressure bearing capability
- FDA compliant butyl molded diaphragm is secured by a clench ring, reinforced and does not fold, bend or crease - limiting wear and tear and air loss with cycles
- 100% pure polypropylene liner separates water from the steel tank shell, prevents corrosion and maintains the quality of drinking water
- 1 in. NPT 100% stainless steel, patented water connection eliminates air loss, corrosion effects and ensures no cross-threading or cracking
- Leak-free, double O-ring-sealed air valve and cap
- Anchorable, corrosion-free, replaceable tank base
- 38 psi pre-charge with 150 psi maximum working pressure
- Durable, rust-resistant 2-part polyurethane exterior paint
- Minimum, the tank you choose must be able to hold the amount of water your pump can supply in 1-minute, please see drawdown chart for details, there is no downside to choosing a larger tank as a bigger tank can reduce pump cycles, thereby extending the life of your pump and conserving electricity
- Note: well tanks should not be used for RO systems or in thermal/hydronic expansion applications
- 5-year limited warranty
- 21.1 gallon of total volume; standard AOW, plain or galvanized tank equivalent of 42 gallon

Questions & Answers
Will this pressure tank work with a tankless water heater?
The PressureWave tanks can be installed and work with a tankless water heater as long as it is within our operating temperature limits. The PressureWave™ tanks minimum operating temperature is 14°F / -10°C (Avoid Freezing) and the maximum operating temperature is 194°F / 90°C. Per our installation guide in the “Installation and Operations Manual” it is recommended to install the PressureWave™ tanks as recommended in order to ensure your tank provides its maximum service life; and it should be installed in a covered, dry area that is not subject to freezing. Our tanks are designed for a wide range of applications, including well water systems, irrigation systems, booster systems, VFD-controlled systems and water hammer arresting. Please review the “Installation and Operations Manual” for the tanks for further installation guidance.
does this tank come with a motor base on top
Hi Chuck ~ No, the vertical PressureWave™ tanks do not come with a pump/motor mount stand, only the horizontal PressureWave™ tank models come with a pump mount stand. The good news, the pump mount stand, model PWN-US-PM, is available for separate purchase and is compatible with all the PressureWave™ vertical tanks.
Use how many psi air go to the tank
Hi Mark ~ this depends on the size of pressure switch that you have in your system. The PressureWave pressure tanks have a pre-charge of 38 psi. Tanks installed with a fixed speed pumping system should be set 2 psi below cut-in pressure. Example: with 20/40; the tank is set to 18 psi, 30/50; tank is set to 28 psi and 40/60; tank is set to 38 psi.
What is the drawdown on 42 gal tank?
We have a drawdown chart on the pressure tank retail box, as the drawdown depends on the pressure switch that you have on your system. For this model/size tank the drawdown for the PWN-US-160LV (42.3 gallon / 160 liter) pressure tank is as follows with: - 20/40 pressure switch = 15.48 gallons / 58.60 liters - 30/50 pressure switch = 13.07 gallons / 49.48 liters - 40/60 pressure switch = 11.34 gallons / 42.91 liters I hope this helps and if you have any other questions, please do not hesitate to ask. You can also find more detailed information at our www.gwsusa.com website.
What size is the box size that the 42 gal pressure tank comes in, I need dimensions for transporting, Thank You
The 42.3-gallon pressure tank (model PWN-US-160LV) package/box is 21.7" length x 21.7" width x 37.8" height.
What are the measurements of the tank?
The PWN-US-130LV (34.34 gallon / 130 liter) PressureWave™ pressure tank has a 16.9” (inch) diameter (width and depth) and 42.2” (inch) height; with a water connection that is 2.4” (inches) height from the tank base bottom/floor to the inlet/outlet water connection centerline.
For the 21 gallon tank what pressure switch should I get?
For our GWS PressureWave™ pressure tanks you can use a standard pressure switch for well pumps in sizes 20/40, 30/50, 40/60, etcetera, but please be sure to set the pre-charge in this pressure tank accordingly. The air pre-charge of this tank is manufactured and set to a 38psi pre-charge, which is the pre-charge needed for the 40/60 pressure switch. Your pre-charge should be set to 2psi below the cut-in of your pressure switch. Example: with 20/40 pressure switch the tank is set to 18 psi, with a 30/50 pressure switch the tank is set to 28 psi and with a 40/60 pressure switch the tank is set to 38 psi.
Where is this manufactured
Our GWS PressureWave™ pressure tanks from 2 - 42 gallon are manufactured in Taiwan.
