Question: is it normal to leave all the red/brown build up after a single distillation?  it gets really thick and needs scaled with vinegar
Document: Ours has run for years. The only thing I would do differently is that I would clean it with vinegar more often so the mineral deposits wouldn't build up and make the interior so unaesthetic.Notes:  Like our other Waterwise, this distiller is fairly noisy. I've got it in the dining room where it's noise is blocked.Pam T~
Purchased this product about a month ago and we LOVE it! We make a gallon of fresh, clean water every night. It tastes great! Now that we are used to tasting clean distilled water, we don't like the weird flavors in tap water.I wash the stainless steel container every morning with white vinegar. There is a little filter that needs to be changed every couple of months, and an extra one is supplied with your order.The unit is sturdy and well made with a nice simple design.
Any possible residual vinegar won't hurt you or the charcoal filter.If fact, I don't use the charcoal filter. I removed the pouch, leaving just the spout. I don't quite understand why one goes through all the trouble to steam distill water then pass it through charcoal, it will leave residue or fines in your water plus the charcoal will contaminate itself after so many uses.Don't remove the fan-head during or immediately after use, as any rising steam will scald your face and arms.
I was looking for a replacement for my Sears water distiller and did some research. The WaterWise 4000 had all the features I liked PLUS it has a glass container!!!! I really recommend it. My friend has one that he bought almost 20 years ago.
We absolutely love this product. Getting it set up initially took a bit of time, but after that it's really easy to use. Some of the other reviewers found it noisy - but it just sounds like a very low air cleaner, not unpleasant at all. The water is really pure - no taste, (water is not supposed to have a taste). We add concentrated minerals for health benefits, which can be purchased at health food stores.
This is okay for 2 people drinking faily often, and a little cooking.Does take some time and needs cleaned every 3 months, I got the filters and cleaning solution.
I run it almost every night. This thing is going to pay itself off in no time. Because of the minerals in the water where I go to school in Alabama I like to rinse off with the distilled water after my shower. I planned on just drinking and cooking with the water I made but rinsing with it after my shower has eliminated my itchy skin and my search for thick lotions, shea butter or body cremes!
Great product, I use every day. It is easy to clean with vinegar and hot water. I wish the water collector was glass, but otherwise I highly recommend this product.
If my fish like it, that tells the whole story. Now if I can provide enough for my family needs too! This unit is running around the clock. Only complaint is that the switch on the front doesn't seem very durable, and be careful opening the top after the unit shuts off or you could get burned from the steam that will erupt from the base upon opening(wait 30 minutes)
I have trying their recommendation of poking a few small holds in the paper that separates the plastic cover from the charcoal. I used a pin, as they suggested. Also, they have offered to send me a six pack of filters as a replacement if I am still having problems. That's pretty good customer service if you ask me. Still, the filter design needs some work.
Answer: yes
