3. Purpose
The X multiblock enables the efficient and low-cost
installation of softeners or limescale protection sys-
tems, eliminating the need to fit the usually essential
bypass pipe with the attendant stagnant water and
appropriate fittings.
Note: This is a maintenance shut-off while super-
vised servicing, inspection or other work is carried
out, and does not involve the permanent shutting-
off of a valve.

The installation of the system and the required mo-
difications should only be carried out by the water
utility or an installation company registered in the
water utility's directory of installers, in accordance
with the AVB Wasser V (General Insurance Terms),
§12.2.
4. Function
The water inlet to the softening or limescale protec-
tion system can be interrupted with the brass X mult-
iblock. In this case, the water supply is maintained
by the integrated bypass (see fig. 4) so that mainte-
nance work, for example, can be carried out.
