Shut off water supply and
unscrew one of the flexible
pipes in order to reduce
the pressure that blocks the
product.
4. The water supply pressure is under 8
bars and yet the pressure in the faucet’s
body is higher. This situation could be
caused by a sudden increase in the
water supply pressure that the backcheck
prevents from dropping, even after water
supply pressure drops under 8 bars.
Clean the orifice or replace
diaphragm.
1. Debris or scale in diaphragm
