SEAGULL IV Seagull Four Built-in Main Unit Only - Switchable Type for Other Water Purifiers

Water Purifier System - Built-in Type
The cartridge is a female thread type RS1SGE.

In recent years, it has changed to a male thread, but the performance is the same whether it's a female or male thread.
Female thread cartridges are cheaper.

In the unlikely event of initial defects (water leakage), we will respond with a refund.

IV Water Purifier System - Please read the following description.

Model Name: SEAGULL IV
Purpose: Water Purifier System

This is for built-in installation.
Please prepare two hoses and a cartridge yourself.

Hoses seem to be sold on the manufacturer's website, the Jōsuiki UP website, and Rakuten Ichiba. Prices vary.

The cartridge is the smaller female thread type (RS1SGE female thread type).

For those who have already installed a different brand of built-in water purifier at home (see the 6th photo).

Hoses are easily mistaken, so the connection part is marked with a circle in the photo. If it's marked with an X, it won't fit the barbed head, so please purchase a hose.

Thank you for looking.
