Question: Is there a warranty included with this filter system? Buying direct from the company includes a warranty
Document: Not likely!I have this water tested yearly and it passes as good water. My neighbors drink this out of their tap. I may try one more set of filters and prefilter with a Brita. otherwise I recommend be careful as this system is expensive and the company seemed rather cold to me. With what I know now, I would not buy one
I love this filter. Easy to set up and refill. The fluoride filters are a real boon. Wish I had included the water level spout in my order. Have had no problem with leaking as some buyers stated. Really,really happy.
The spigot is PLASTIC. It off-gasses and broke after a few uses. The fluoride water filter is encased in---PLASTIC. What's the point here for paying this much money?If you foolishly promote their business by buying something from them, buy the ceramic filters and DIY.
One time the filter caps fell right off (the company said it was a bad batch).So now I'm paranoid. If we don't test every batch of water, how do we know the filters are actually working? Most of the time, we couldn't tell by taste that they were failing; it was only the presence of red dye in the water when we tested that alerted us.
I like my Berkey water filter, but the spigot is leaking. I tried to tighten it from the inside, but it keeps on leaking. The Big Berkey is expensive. If this continues to leak, the base will eventually rust. I'd like the company I bought it from to offer me a replacement spigot. The Big Berkey itself is filtering the water well.
My husband stuck a key ring in the hole and we're getting by until I throw the whole thing out the window or breakdown and buy the part. I'm shopping for alternatives if anybody can recommend a better filter.They do get points for good customer service, though the company could never explain WHY the filters kept failing. I appreciated them sending the replacements out right away, but it gets pretty annoying to have to wait to use it till new filters arrive and then wonder how long until those ones go bad.
The Berkey filters installed without any issues, and the fluoride filters were the same, no issues, just follow the included directions and you will be fine.The quality of the water from the Berkey exceeds our expectations, there are no foul or weird tastes and the water is crystal clear.
We have been using under sink filter system but this is much better. Removes more contanimints and the water is delicious. Should be a lot cheaper too.
totally exactly everything you want in one package. get the fluoride filters with it. you will not regret buying this!
)There is no evidence the Berkey filter with or without the optionalelements is superior to any RO system. Since Berkey does not providecomparable test data, we have no way of knowing with any certaintythough basic chemistry and the data from a simple TDS meter stronglysuggests the Berkey filter is not effective against dissolvedcontaminants.
Answer: yes
