DUALHYDRAVIS™ GUN METAL GRAY SERIES
Fontana DualHydravis Gun Metal Gray Faucet FAQs
Three-hole gunmetal basin faucet with 304 stainless-steel
construction, brass valve core, dual crystal handles
and independent hot/cold water control.
✥
Three-Hole Rough-In Requirements?
+
The FS20025GMG requires three deck openings
for the central spout and two separate
crystal-handle assemblies. Verify hole
spacing, countertop thickness, spout
alignment and under-deck fastening clearance
against the installation drawing before
drilling or countertop fabrication.
◇
Stainless-Steel Body Installation?
+
The DualHydravis incorporates a 304
stainless-steel faucet body with a
Gun Metal Gray finish. During mounting,
verify correct gasket placement,
component alignment and secure
fastening. Protect finished surfaces
from abrasive tools, scratches
and excessive mechanical tightening.
◯
Crystal Handle Commissioning?
+
Two colour-crystal handles independently
control hot and cold water delivery.
Verify correct supply orientation,
smooth handle travel, predictable
temperature adjustment and complete
shutoff. Confirm both handles have
sufficient operating clearance from
the spout and nearby countertop fixtures.
↻
Cartridge Endurance Verification?
+
The manufacturer specifies cartridge
durability of 500,000 opening and
closing cycles. Inspect the handles
for increased operating resistance,
persistent dripping and incomplete
valve closure during maintenance.
Actual service life depends on water
quality, frequency of use and
operating conditions.
⌁
Water Pressure Test Parameters?
+
The published water-pressure testing
value is 1.6 MPa. This identifies
the stated manufacturer test condition
rather than the normal continuous
operating-pressure range. Verify
permissible supply pressure using
the latest technical specifications
before commissioning the faucet.
⌂
Air Pressure Test Verification?
+
The product specification lists
air-pressure testing at 0.6 MPa.
Following installation, inspect
accessible supply connections,
valve interfaces and sealing points
for leakage using the appropriate
approved plumbing commissioning
procedure. The stated factory test
value is not an onsite test instruction.
⚙
Brass Valve Core Diagnostics?
+
The DualHydravis uses a brass valve
core for mechanical water regulation.
Flush the hot and cold supply lines
before final connection to minimize
debris contamination. If flow becomes
irregular or dripping continues after
closure, isolate the supply and inspect
valve components for sediment, wear
or incomplete seating according to
the manufacturer service instructions.
⌕
Gunmetal Finish Maintenance?
+
Clean the Gun Metal Gray surface and
decorative crystal handles using a
soft damp cloth and compatible mild
cleaner. Avoid abrasive pads, polishing
compounds, acidic detergents and
aggressive chemicals. Rinse and dry
exposed surfaces to reduce water
spotting and mineral accumulation.
