Frequently Asked Questions

Q.Can I replace the showr head myself?
A.Yes. While many people think they can’t do it, it is very easy to remove the old shower head byunscrewing it counter-clockwise. The new Ariamisto Bollina shower head is just as easily screwed on. If the old shower head cannot be removed by hand, wearing rubber gloves will make it easier to grip and turn.

A.Most Japanese manufacturers are suitable including TOTO・INAX・SAN-EI・KAKUDAI・MYM. TOTO・INAX・SAN-EI・KAKUDA. TOTO・INAX・SAN-EI・KAKUDA and gaster may need to use one of the three adapters included with the product. MYM will use the “M” adapter, KVK will use “K” and Gaster will use “G”
Q.Can I use the shower in areas with low water pressure?
A.The water flow may be poor in areas with extremely low water pressure. The water saving rate may also be affected due to water pressure or the location the shower head is installed. There are water valve apapters included (Ariamisto x3, AriamistoⅢ x4) that are suitable for low water pressure areas.
Q.Can I install the valve?
A.Yes. Initially adapter #2 is installed. You can change the valve according to your own preference. Remove the shower head from the hose. Remove the valve using a screw driver. Replace it with another valve. A full description is included with the product. This is available on Ariamisto (TK10001) and Ariamisto (TK-1003).
Q.Is there a cartridge?
A.No. The Ariamisto, AriamisoⅢ, Bollina, Bollina PRO don’t need any extra cartidges
Q.What is the difference between micro bubble and micro nano-bubble?
A.A micro bubble is said to be 50μm in diameter whereas a micro nano-bubble is 0.1μm in diameter. 0.1μm is 1/10000 of 1mm so obviously it is not visible with the naked eye. Micro bubles will be generated in the water, float to the surface and disappear whereas micro nano-bubbles are much smaller and will remain in the water for a long period of time.
Q.Do you produce original OEM products?
A.Yes. We will produce this with the Bollina and Bollina PRO shower heads. We have already produced a first official shower head in Japan with the FC Gifu original Bollina shower head.
