A reservoir is a large storage tank that holds oil underground. Oil and gas are pumped from the ground into the reservoir, where they remain until extracted by wells drilled through it. The largest reservoirs in Texas hold billions of barrels of crude oil or natural gas liquids (NGLs).

Reservoir: Frequently asked questions

What types of Reservoir are there and what determines a good product?

There are two types of Reservoirs – the first is a “fixed” reservoir, which means that it has no moving parts and can be placed anywhere. The second type is an “integrated” reservoir, which features a pump to move water from one place to another. Integrated reservoirs cannot be moved once they have been installed in your system (although you may remove them for maintenance purposes).

A good reservoir has a large surface area and high porosity. It should be easy to clean, have no sharp edges or protrusions that can damage the filter membrane, and it must not leak when under pressure. The material used in its construction is also important; polypropylene (PP) is preferred over polyethylene terephthalate (PET). PP will last longer than PET because it does not degrade as easily from UV light exposure.

Who should use a Reservoir?

Anyone who wants to improve their health and well-being.

Based on what criteria should you buy a Reservoir?

The first thing you should consider is the size of your system. If it’s a small system, then any reservoir will do. However if you have a large cooling loop with multiple radiators and pumps, then there are some things to take into consideration when choosing which one to buy.

The most important aspect for me was that I wanted something that would be easy on my eyes while still being functional as well as aesthetically pleasing in my build (I’m an artist). It also had to hold enough water so I wouldn’t have too many trips back and forth from the sink filling up reservoirs every time I needed more coolant added or changed out completely due to evaporation loss over time (this happens especially during summer months where temps can reach 100+ degrees Farenheit) . My final criteria were price point because let’s face it. we all want our builds looking great but not at the expense of breaking our bank accounts.

The first thing you need to look out for is the quality of material that has been used in making it. This will determine how long your reservoir can last and whether or not it will be able to withstand a lot of wear and tear. You also have to check if there are any leaks on the product because this could cause serious problems with your computer system as well as damage other parts inside the case such as motherboards, graphics cards etcetera. Another important factor would be its compatibility with different types of cases so make sure that you choose one which fits perfectly into yours without causing any issues whatsoever.

What are the advantages and disadvantages of a Reservoir?


A Reservoir is a great way to store water for long periods of time. It can be used as an emergency backup supply or even just to have extra drinking water on hand when you need it.


The disadvantages of a reservoir are that it is not very portable and can be heavy. It also takes up more space than other water storage options, such as bottles or collapsible containers. However, many people choose to use reservoirs for their convenience in the backcountry when they will have access to plenty of fresh water sources along the way.
