Black Primer for Use with Gravity-Fed Water Filter Systems Equipped with Black Berkey Elements

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.

It works although not exactly as advertised. It did prime the filters and fix my slow filtering issues. If your facets can’t accommodate the ring this is an alternative

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.

Great water saving tool for backfeeding a clogged pore water filter

This pump doesn't work at all. I assembled it correctly too. I had no problem following their directions. I tested it in water and it worked fine pumping water out of a glass. The nut that connects to the plastic threads of the black berkey's did not thread properly. I had to push very hard to get it to grab the plastic threads on my filters; and it didn't screw down all the way. Not happy about that. Also, the plastic pipe on one side did not stay on very well. It needed a radiator clamp. I saw another review about this issue.It cost about $30, with tax. I sent it back. It's a rip off.

This is overpriced for what it is-- and it turns out I did not even need it. Reading the product description and reviews led me to conclude I was really going to need this thing to set up my new Berkey. That was not the case, the little tan ring works just fine). The instructions are poor, so I ended up having to watch a You Tube and go the Berkey site to figure things out. Once I got it together I primed one filter, then figured just for kicks to try the normal process. It worked just fine. I never even needed this bulb and tube thing, the faucet works fine with the tan ring. Save your money, you don't need this. Priming is not an art form, but even a pull out sprayer faucet will work with the tan rings they include.

Should help expedite the priming!

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.

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
