Testing the Limits - How Far, How High, How Low

When out in the wilderness, access to clean water is essential for any outdoor enthusiast. This is where the PYURIFI water purifier comes in. With its reputation for reliability, many outdoor enthusiasts trust PYURIFI to provide clean and safe drinking water in any situation. But just how far can you push this water purifier? In this article, we put the PYURIFI water purifier to the test and share our findings on its performance.

When it comes to water purification, PYURIFI is a name that many outdoor enthusiasts trust. But have you ever wondered how far you can push this water purifier? We decided to put it to the test and see just how much it could handle.

Using a 25-foot long 1/4-inch ID hose on the suction side of the unit and sitting at around 3 feet, it took about 2 minutes to prime. The flow rate was good at 1 liter per minute, meaning customers can use a longer hose if they wish (including 4 feet on each side of the unit).

We then tested the PYURIFI's performance at different levels of vertical lift. This is what we found:

  • 16 feet of head, the flow rate was 250ml per minute.

  • 12 feet, it was 350ml per minute,

  • 9.5 feet, it was 500ml per minute,

  • 9 feet, it was 650ml per minute,

  • 7 feet, it was 680ml per minute,

  • 6 feet, it was 900ml per minute,

  • 4 feet, it was 1 liter per minute. 4-6 feet is the recommended operating zone.

While performance at 9 feet was decent, the pump took a beating, and we expect to see a reduction in its lifespan if it is operated regularly at this height. The pumps are rated for about 500 hours of continuous run time (approximately 7,500 gallons) at 1 liter per minute (up to around 4 feet of head). However, we anticipate a longer life out of the pump since they are generally intermittently used. It is also important to note that dirty filters may cause lower output.

But there's more to the story. We discovered that the pump's output slowed when the filtered water temperature was below about 45 degrees Fahrenheit. This reduction in production can be attributed to several factors. First, the pump diaphragm stiffens in colder temperatures, affecting its overall performance. Second, water viscosity increases at lower temperatures, making it harder for the pump to move the water through the system. Lastly, ice crystals can form within the carbon filter, further restricting the flow.

Considering these findings, if you need to filter super cold water, it's a good idea to let it warm up beforehand. This precaution will help maintain the PYURIFI water purifier's efficiency, extend the pump's life, and ensure a smoother filtration process.

In conclusion, the PYURIFI water purifier is a reliable choice for outdoor enthusiasts who need access to clean water. While it has its limitations, the purifier performs well in a wide range of scenarios. However, it's important to keep in mind that the pump's performance can be affected by factors such as vertical lift and water temperature. By understanding these performance considerations and taking the necessary precautions, users can ensure that the PYURIFI water purifier remains efficient and effective for years to come.
