What Are Concealed Stop Valves?
A concealed stop valve is a brass valve built into the wall, with only the handle and flange showing. It opens or shuts water to one pipe line. It does not mix hot and cold water, so it does not set the temperature; for that you need a wall mixer or diverter. This page has the 3/4 inch (20 mm) size, for the bigger supply line; 1/2 inch (15 mm) is for regular lines.
Where are They Used in a Household?
In a household, concealed valves can be used in various areas including but not limited to the bathroom shower or tub, the basin, or even in the kitchen. The main advantage is that they offer a neat, clutter-free look, as all the plumbing is hidden behind the wall or panel.
