– If water continues to drip from the
safety valve after the heating
system has been switched off, the
water pressure is too high (>6 bar),
or the safety valve has been
contaminated with dirt or is
defective.
Note with regard to copper pipes:
No connections made of copper
may be installed directly on the
device. We recommend that red
brass or plastic transition fittings be
used as connection isolators for the
pipe connections.
