Special information
- Install a type-tested safety valve in the cold water
supply line. For this bear in mind that, depending
on the static pressure, you may also need a pres-
sure reducing valve.
- Size the drain so that water can drain off unim-
peded when the safety valve is fully opened.
- Fit the discharge pipe of the safety valve with
a constant downward slope and in a room free
from the risk of frost.
- The safety valve discharge aperture must remain
open to the atmosphere.
