Portable water purifier; Wellspring; FAQ 5. The water is not running!

Filter can suddenly not run. Slow flow shows the sign. Below three cases are main reasons.

First, when we use Wellspring for a long time while not pretreating.

If you filter contaminated water which contains coarse-grained materials, without pretreatment, the pores can get clogged by the particles. So if the water has visible sized particles, make sure you pretreat the water first. In this case, try to take Wellspring apart. You will see that a lot of visible foreign substances are piled up on AF and DF filter. Then what should we do with the filter? Just wash it with running water. If you hand-rub the filters like when you do laundry, it can be torn.

 

 

Second, when the AF is used for a long time.

AF removes organic matter by absorbing thus if AF contains a lot of organic matter, flow rate can be decrease. It cannot be used after a certain period of time (maximum 6 months). But this is the average period so if you filter relatively clean water such as rain water, Wellspring can be used longer than the average period. After replacing AF filter, you can get clean water again.

 

 

Third, when using hollow fiber membrane without backwashing.

 

 

As mentioned in the instructions, hollow fiber membrane becomes less efficient without backwashing.

If you do not backwash Wellspring for months, you can still get clean water but the flow rate will decrease and eventually clean water will not run. So how about backwashing Wellspring at least once a week and using it for a long time?
