Water from my Nikken Aqua Pour or Waterfall tastes funny or bad

If the water tastes bad and you have NOT changed the filters recently then it is probably beyond time to replace them.

If you have just replaced your filter cartridge or you are setting up your system for the first time then the cartridge needs to be rinsed out. During shipping the cartridge can get knocked around a lot and shake some of the filtration material loose. The easiest way to rinse out the cartridge is to fill the top tank and let it drain completely into the lower tank. Once complete, drain the water out through the spigot and pour it back into the top to drain through again. Two or three cycles through will take care of it in most cases though sometimes I have seen it take six to eight cycles for the taste to go away completely. The water is still safe to drink.

How do I use the Aqua Pour micro sponge or ceramic dome pre-filters?

The Aqua Pour ships with two pre-filters, the micro sponge and the ceramic dome. You can only use one of them at a time, so you have to choose one or the other.

The micro sponge pre-filter: The micro sponge comes as a hard, dry disk. If you choose to use it you will need to soak it for about a half hour to let it expand out then place it in the well at the bottom of the top tank on your Aqua Pour. If you don’t let it soak up water first then it will be too small to stay in place and will float to the top. It takes about 45 minutes for the top tank to drain completely into the bottom tank when you use the sponge.

The ceramic dome pre-filter: To use the ceramic dome you will need to prepare it for use first. Take it out of the packaging, turn it upside down, and fill it with water through the little hole in the bottom. Then place it in a bowl of water and let it soak over night. After it has soaked, keeping it upside down and as much water inside as possible, screw on the spacer to the threads around the hole, then place the top tank upside-down over the spacer so that the dome is inside the tank and attach the nut that holds the ceramic dome and spacer in place to the bottom of the tank. Now turn this assembly right side up and set it on the Aqua Pour.

This process will soften the ceramic material and keep air out of the interior of the dome so that water flows through it easily. It should take about 5 hours for the top tank to drain completely when you use the ceramic pre-filter.

How do I prepare and assemble by PiMag water filter?

The PiMag Waterfall is the current water filter from Nikken. It comes assembled in the box though you have to disassemble it to install the filter cartridge once it is prepared. The video below from Nikken shows how to do this.

If you have the older Aqua Pour then you want to prepare the filter cartridge as you would for the Waterfall. See the video above. The Aqua Pour has a choice of two pre-filters, a micro sponge or a ceramic dome. You only use one or the other. If you choose the sponge, put it in the water with the filter cartridge as in the video above. If you choose the ceramic dome then prepare it as described in the Pre-filter answer above here. Once everything is prepared, this video shows you how to assemble your Aqua Pour.

How do I clean my PiMag Aqua Pour or PiMag Waterfall?

The best time to clean your Aqua Pour or PiMag Waterfall is when you change the filter cartridge. Disassemble your water filter and dispose of the parts you are replacing. You can wash out the tanks with hot water and a very mild detergent then rinse them thoroughly. You can rinse the stones under running cold water if you aren’t replacing them yet. Use only cold water on the filter cartridge and any of the seals.

Once clean, reassemble your unit. Click here if you need help reassembling your unit.

General Questions – Answers

How do I buy a PiMag Waterfall or replacement parts?

Go to my PiMag Waterfall page and either click on the Waterfall itself to order a new unit, or click on the picture of the replacement parts to order the filter cartridge and/or the mineral stones.

Nikken recommends that you replace the filter cartridge every 3 months and the mineral stones every 12 months.

Are Nikken water filters BPA free?

Yes. The Aqua Pour and PiMag Waterfall systems as well as the current water bottle are all BPA free.

What pH can I expect from my Nikken gravity water filter?

PiMag Waterfall – Nikken claims a pH range of 8.5 to 9.5 for the Waterfall. When the cartridge is new you should get water that is close to 9.5 pH and it will gradually come down to 8.5 pH over the 3 month life expectancy of the filter cartridge.

PiMag Aqua Pour – Nikken never made any specific pH claim for the Aqua Pour. I usually had around 7.5 pH from my Aqua Pour.

What is a gravity water filter? How do I use one?

A gravity water filter is a water filter that is powered by gravity.

In the case of the PiMag Waterfall, it is a stand-alone water filter. You pour water into the top tank, usually called the “fill tank.” Over time, gravity pulls the water down through the filter cartridge into the bottom tank, the supply tank.

The supply tank on the Waterfall holds just under 1.5 gallons, so water is always available as long as you add more water when you take some.

If the filter cartridge is prepared properly the water flows through it pretty fast. I haven’t timed mine but I’ve never had to wait too long when someone forgets to put more water in after draining it.

Do the Nikken Aqua Pour and PiMag Waterfall have the same size lid?

No. The Aqua Pour is round and the PiMag Waterfall is oval shaped.

How long can PiMag water sit?

I heard all the other distributors debate about this back when I started out as a distributor.

The water should last as long as you need it to in the supply tank of the filter. If you decide to take it out of the filter and refrigerate it, then it should maintain its properties over night.

It really comes down to how much water you drink. If you drink the recommended amount of water every day then you should be draining and refilling your Waterfall at least ever other day if you are the only one using it. If you have a family of four and use the water for cooking too, then you probably drain and refill it a few times every day.

What are the benefits of a Nikken water filtration system?

There are many benefits to a Nikken water filtration system.

Check out one of my blog posts about how to get great tasting water for a more in-depth answer. I’ll summarize some of the benefits here.

A PiMag water filter will remove many of the impurities in your drinking water, including most of the chemicals, like chlorine that cities put into it.

They make the water alkaline. The PiMag Waterfall adjusts water to somewhere between 8.5 and 9.5 pH.

The PiMag Waterfall is a stand-alone gravity water filter. That means it doesn’t use electricity or water pressure to filter your water. It isn’t in the way at your sink. And it holds water so you don’t have to go without when the power goes out.

How does the PiMag Waterfall ionize water?

Yes, the PiMag Waterfall does ionize the water to a small degree. They made a big deal about it when it first came out but they don’t talk as much about it now. The ionization provides a minimal benefit and they hype was created by another water filtration system (an outrageously expensive one that requires electricity and a connection to your faucet).

Do the Nikken PiMag water filters remove fluoride?

Nikken doesn’t claim to remove fluoride because they can’t remove better than 95% of it. I’ve always been told that it removes between 60-65% of the fluoride.

Fluoride is notoriously hard to remove from water. I was researching other systems that claim to remove fluoride but found that a lot of them don’t do a whole lot better. It appears there is a big difference between “removed fluoride” and “eliminates fluoride.”

What does the Nikken PiMag Optimizer do?

The PiMag Optimizer used a magnetic field to create a water vortex within the Optimizer pitcher.

The vortex added air and more minerals to the water to make it slightly more alkaline. My water never reached 8 pH, so the Waterfall does a much better job by itself.

Nikken Shower Filter Answers

How often do you change the filters in the Nikken shower head?

Nikken carries replacement filter cartridges for both of their current shower filters – a hand-held unit and a wall-mounted unit as well as the previous wall-mounted unit.

Actually both the current and previous wall-mounted shower filters use the same filter cartridge.

PiMag MicroJet Hand-held Shower Filter – Nikken recommends that you change the filter cartridge every 3 months. The replacement cartridges come in 2-packs so you only need to order new ones every 6 months.

PiMag MicroJet Wall-Mounted and PiMag Ultra Shower System Filter – Nikken recommends that you change the filter cartridge every 6 months.

All of the PiMag replacement parts are available here.
