Black Primer for Water Filter Elements/Purifiers

So much easier than trying to prime using the tap . Primed properly and the filters work a lot faster than the last new set did. Worth buying

Needed gadget for the Berkey filter prep. I couldn’t pret my filters without this tool. I tried and tried and the water was coming so slowly. I used this tool and my filters working great now.

Like others, I can’t believe I paid nearly £30 for a few tubes and a pump! However, it makes easy work of priming the Berkey and job done tidily and quickly within 5 minutes. Considering it’s almost impossible to prime the filters using a tap, I would argue that the berkey kit should be shipped with something like this including in the price- especially given the price is pretty high as it is. -1* for the audacity

Just what I needed since I can't prime with my taps.oerfwct and easy

One valve was missing so I sent it back

Yes very happy with Berkey - water very clear and tasty.

Great item. Works very well and does the job. Reason for 2 stars, well over priced for abit of plastic.

The primer worked fine. It was the filters I had purchased were faulty, so I haven’t used that Berkey in several months now I’m just am hesitant to order the filters again.

Leider hat das mit dem Wasserhahn nicht geklappt, so dass die neuen Filter nicht in Betrieb genommen werden konnten. Ich hab dieses Set bestellt, es hat einen Moment gedauert bis man die zwei Filter "gebrieft" hatte, aber es hat letztendlich gut funktioniert. Wasserfilter läuft wieder.

I don't want to run tap water into a filter that is supposed to remain sterile inside, so until I bought this I had to prime the filter the long way. This pump is a life saver, in max 10 minutes you're done.

My sink faucet does not have a smooth surface (it's a spray head) so it could not make good contact with the priming button. So, I ordered this primer. It worked beautifully. Both filters were primed and ready to go in about 15 minutes. Another advantage to having this on hand is it will work without running water (in case of an emergency, etc.). Putting the primer together can be tricky, and the instructions are not very good. I watched a YouTube video that explained how to put it together (link at end of this review). Here are the things you'll want to know while assembling the primer. The parts consist of: 1 bulb with different size holes on each end, 2 identical plastic tubes, 2 identical "valves", 1 hexnut and 1 one "angle piece" (this is where the water exits the primer). The little "valve" parts (2) have a smooth side, and a ribbed side. They have to be attached in a certain way so the pump works correctly. Working left to right, this is how the pieces all fit together. I laid them out in order then assembled the tube sections first and connected them to the bulb last:: Hexnut > tube > smooth end of valve A into tube > ribbed end of valve A into LARGER hole in the bulb > smooth end of valve B into smaller hole in bulb > ribbed end of valve B into 2nd tube > angle piece into 2nd tube. Get a container that is deep enough to where the filter can be completely submerged, and fill it with water. Screw the hexnut into the filter and place the filter into the water (it will try and float initially as it's full of air). Don't worry about it being fully submerged while you're pumping as it will gradually sink as it fills with water. Begin pumping. It took me about five or six minutes to fully prime. A bit of water came out at first, and then just air for quite a while. Part way though I did notice there was a suction issue (it took a long time for the bulb to "re-inflate" so I made sure a little bit of the filter was above water and loosened the hextnut just a bit, and that worked. It was not creating 100% vacuum at that point but it worked and I was able to prime the filters. My only gripe about this is that the rubber bulb STINKS like nasty rubber. It's getting stored at the back of a closet because I am very sensitive to chemical smells. However, the filter functioned perfectly so I'm still giving it five stars. I did not have a problem inserting the pieces into one another like other reviewers mentioned (just remember the bulb has two different sized holes). I think the hardest part was inserting the hexnut into the tubing, but that just took a few moments. The primer comes unassembled because you can reverse the direction of the valves if you want to purge water from the filter.
