Reviews of the Best Well Pressure Tank
Amtrol WX-202 Well Pressure Tank
Amtrol’s WX-202 is specifically made for use in residences because it has a tall and slim design that reduces its floor space requirements. This means that it can easily fit along narrow plumbing lines in your home.
Additionally, the unit has an appliance-like blue finish, which qualifies it to be installed anywhere in the house because it blends quite easily.
Construction wise, this tank is made using high-strength steel, making its shell very strong and durable, which is ideal for protecting all the internal components from external damage. It also features a stainless-steel air valve that is welded rather than threaded so as to prevent any pressure loss.
On the inside, a butyl diaphragm is used to separate the air and water chambers, and it is combined with a virgin polypropylene liner to create a 100% corrosion resistant barrier between the water and the metallic outer frame. Both are secured to the frame using a positive hoop ring seal, making it very reliable.
In terms of volume, the WX-202 has a capacity of 20 liters and comes pre-pressurized at 38 psi from the factory. At the pressure switch, the cut in pressure should be set at 2 psi below this value, while the differential pressure between the cut in and cut out should not exceed 20 psi for the best results.

Important Things to Consider When Buying Best Well Pressure Tank
Type
There are 3 types of pressure tanks to consider. These are:
Air-over-water tanks: these are the older types of well pressure tanks and they have only one compartment inside that houses both the water and pressurized air. The problem with this type is that over time, the pressurized air dissolves in water and this reduces the pressure inside.
Diaphragm tanks: diaphragm tanks incorporate the use of diaphragms, which separate the air and water chambers so as to avoid air from dissolving and thus, maintain the water pressure. The problem with them is that the diaphragm may detach under high pressure if it is not secured tightly.
Bladder tanks: these utilize a bladder or an air cell inside the water reservoir instead of a diaphragm. This ensures that the water and air are separate and eliminates the problem of detaching, making them the best option to consider when buying a well pressure tank.
Capacity
There are two ways at looking at the capacity factor. If you want fresh water that is being pumped straight from the well, then you should buy a small capacity tank because it will give you a smaller drawdown. However, this will cause a lot of strain to your pump because it will be running after very short intervals.
On the other hand, if you prefer less energy consumption, then you better buy a bigger tank because it will hold more water and thus, require fewer pump restarts over time due to the large draw down.
Construction
A pressure tank’s construction mostly focuses on its outer shell, which is usually made out of stainless steel. Stainless steel makes these units very sturdy and capable of withstanding falls or even small dents without cracking open.
The problem with such tanks is that it makes them very heavy and thus, harder to handle, especially during installation. Stainless steel may also rust if exposed to the elements and therefore, the tank must be regularly maintained so as to ensure the metallic surface is sufficiently coated to prevent wear and tear.
On the other hand, fiberglass pressure tanks are extremely durable and do not rust even when exposed to the elements. Additionally, they are very lightweight, making them very easy to handle during installation.
The only problem with fiberglass is that it may crack open much easier as compared to stainless steel if it falls or is hit by a sharp object.
Coating
Another thing to consider is the coating applied to these materials. For stainless steel, whether it’s coated using polyester, high gloss enamel or any other lining, this layer must be waterproof so as to protect the underlying metallic surface from rusting.
Fiberglass tanks must also be coated externally but not for waterproofing. This layer is important for additional strength against dents, scratches and other minor defects.
Pre-charge and Maximum Operating Pressure
Pre-charge basically defines the air pressure that the tank comes bearing in its air chamber from the factory.
It is important to know this value so as to determine if the pressure is suitable for your water supply system or if it needs any increase or decrease. It is also important to know the maximum operating pressure so that you do not exceed this value as you increase the air pressure.
Conclusion
Pressure tanks are vital components in a well water supply system and as such, you must have the best well pressure tank so that you get water constantly and at the right pressure all around your home or commercial building.
After going through the content above, selecting the most ideal tank should not be such a hard task because every important detail about these products is clearly laid out for easy comparison and selection.
