Under-Sink Water Filter Installation
Direct-connect filter plumbed in under the kitchen sink
Installing an Aquasana Claryum direct-connect under-sink filter: shutting off supply, mounting the housing, tying into the cold line and leak-testing before cleanup.
The job
The homeowner wanted filtered drinking water at the existing kitchen faucet without surrendering the whole cabinet to equipment. We installed an Aquasana Claryum direct-connect unit: supply off and drained, cabinet cleared and protected, housing mounted high enough to swap cartridges without pulling the unit, then a full flush and leak test before the cabinet went back together.

The problem
A homeowner wanted filtered drinking water at the kitchen tap without losing the whole cabinet to bulky equipment.
Our recommendation
A direct-connect under-sink filter tied into the cold line, mounted with cartridge-change clearance planned in from the start.
The result
Filtered water at the existing faucet, a tidy cabinet with room to swap cartridges, and no drips at any connection.
Scope of work
What we did
Process
How we approached it
Step 1
Shut off and drain
Closed the cold supply stop and drained the line so the cabinet stays dry when the fittings come apart.
Step 2
Clear and protect the cabinet
Emptied the cabinet and put down protection under the work area.
Step 3
Mount the housing
Fastened the filter housing to the cabinet wall with enough clearance below to drop cartridges out at change time.
Step 4
Tie into the cold line
Connected the direct-connect fittings to the cold supply, keeping the tubing runs gentle with no kinks.
Step 5
Flush and leak-test
Flushed the new cartridge per spec, then pressurized and checked every joint dry before reloading the cabinet.
