CRESTAFLOW™ HERITAGE SERIES
Fontana CrestaFlow Brushed Nickel FAQs
Brushed nickel three-hole deck-mounted basin faucet with 304 stainless-steel body,
brass valve core, dual crystal handles, and independent hot/cold control.
✥
What Is The Faucet Body Material?
+
The FS20021BN specification identifies a 304 stainless-steel
faucet body. The material provides corrosion resistance,
structural stability and durability for repeated bathroom
basin use.
◇
What Valve Core Material Is Used?
+
The CrestaFlow uses a brass valve core for water control.
Flush both hot and cold supply branches before final
connection to reduce construction debris entering the
internal valve assembly.
◯
What Installation Layout Is Required?
+
The faucet uses a three-hole deck-mounted configuration with
a central spout and two independent crystal-handle controls.
Confirm deck drilling, basin position and below-counter
service clearance before final fastening.
↻
What Is The Cartridge Cycle Rating?
+
The published cartridge lifetime is 500,000 open-and-close
cycles. Proper supply flushing, secure mounting and periodic
inspection help maintain reliable valve performance over
long-term service.
⌁
What Water-Pressure Test Is Specified?
+
The product specification lists water-pressure testing at
1.6 MPa. This is a published product test value and should
not be interpreted as the normal operating pressure required
for the installed plumbing system.
⌂
What Air-Pressure Test Is Specified?
+
The CrestaFlow specification lists air-pressure testing at
0.6 MPa. Final site commissioning should still include
leakage inspection of accessible supply joints, valve
interfaces and below-deck connections.
⚙
How Should The Crystal Handles Be Commissioned?
+
Two colour-crystal handles independently regulate hot and
cold water. Verify correct supply orientation, consistent
handle alignment, smooth movement and positive shutoff on
both control assemblies.
⌕
Brushed Nickel Finish Maintenance?
+
Clean the brushed nickel surface and crystal handles with a
soft non-abrasive cloth. Avoid aggressive chemical cleaners
and periodically inspect the outlet, mounting hardware and
accessible supply connections.
