Black Berkey Primer

They are very comfortable, my first try with barefoot and they really are all they say they are. True to size.

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.Here is the link to the assembly video on YouTube that helped me: [...]If the link does not appear in this review, you can search YouTube for the video titled: Using a Black Berkey Primer, Part 2

I bought this to clean my Black Berkey Filters and just used it the other day. It cleaned the "junk" off of them, by taking it off the filters, not scraping it off with a vegetable peeler like is suggested by Berkey. It pushes the junk out of the filter, so it washes away, while priming it for the next go round with filtering water.Our water is "city water" and full of so much stuff it is amazing when you first take the filters out, how much, what appears to be mud, is on them. I washed them off, then used this to push the other mud out of the filters that was being sucked into the filters as I used it to clean my water.I know that when I refill my Berkey, it sure does filter faster and that is good for me. I only have a small Berkey, as there is only two of us, but sometimes I find I need more water than usual and since cleaning out my filters, I can get it filtered again, in about an hour I would estimate.Well worth the cost and so easy to use.Glad I saw a video on Youtube on this, as I feel it will save me a lot of money in the long run, by not Peeling the filters as is directed by Berkey and the filters will last a lot longer.

The media could not be loaded. I was going to give this a max rating of 2 before my husband solved the problems. There are two problems: 1. It came with bare instructions without adequate diagram of the valve placements and it is easy to get it wrong without that. 2 The product isn't well designed because the tube insert on the input side is loose enough for air to get in ending up in priming pump not working well. After I struggled with it for 30-40 minutes, both these issues were thankfully solved by my husband so it worked really well and really fast.Two things he had to do:1. Put a tourniquet like contraption on the input side of the "tube & valve overlap" to make the connection tight enough to not let air in so that the pump would work efficiently without sucking in extra air.2. Keep the filter element COMPLETELY submerged under water to make it work without wasting time on pumping air in and out for a long time before water could come out.We thought we'll record it so other people could benefit from our experience. Please watch the video to know what I am talking about and make it easier on yourself to use this priming tool. We recorded 2 videos of different problematic parts but Amazon only lets us upload one video per review.

It is important to read all of the multiple sheets of instructions for all of the individual parts. When done well the system is installed correctly, it works great. It is important to prime the filters and remove all shipping plugs from the white fluoride, etc. I neglected to remove the bottom plugs and the water couldn’t flow through the filter. I reread the instructions, re-primed the filters and realized that I had overlooked removing two blue plugs! I’m really happy with the unit now and plan to take it with me on an annual 2 week vacation so I don’t have to buy bottled water in glass bottles to get healthy water to drink.
