これさえ読めば安心! How to Install Water Softenerの進め方を順番に解説します。

Before you channel your inner Bob Vila, gather your gear. You will need: an adjustable wrench, a pipe cutter (or a hacksaw if you like a workout), Teflon tape, a bucket, and two flexible hoses. And a friend—because holding a heavy tank while threading pipe is a two-person job.

Pro tip: Buy a small brass bypass valve. It costs fifteen bucks but will save you from turning off your entire home’s water every time you need to clean the brine tank.

The softener itself should be sized for your household. A standard 32,000-grain unit works for 1-4 people. Any bigger, and you are just showing off. Any smaller, and you will be refilling salt like a Victorian coal keeper.
