Because the unit bath with toilet in the one-room apartment in the house has passed more than 10 years, the water in the tank did not stop completely and tried replacing it because it began to leak with little by little Chorochoro.
As for the water supply, it is no better than an amateur, but I finished work in about 5 to 10 minutes after closing the main plug.
The water leakage repair explanation video on the product page is the highest. Because monotaro is a professional craftsmen opponent, most products selling it has no information such as explanation or usage. If anything, I think that the price is cheap, though I think that this kind of unkind site in this time of the world.
So, if you can see the materials and movies of the installation method with all the products like this product, I think that the opportunity to purchase here will increase without doubt. Even for finely cheap goods, I think that it will come to be able to purchase with confidence if parts usage such as accessories of tools and tools, especially power tools also have usage instructions.
