In Silent Hill: Townfall, the SWPD Clamp Release Puzzle requires balancing three hydraulic pressure manifold dials to exactly 120 PSI (Standard: Valve A = 35 PSI, Valve B = 70 PSI, Valve C = 15 PSI) before throwing the manual override lever . For the Island Clinic VHF Radio transmission, calibrate Simon's portable CRTV device to 94.3 MHz with an oscillation offset of +12 kHz to filter background static . The decoded audio broadcast yields the pharmacy locker code 7-4-1-9, unlocking the Community Garden Key resting on the terracotta plate on the corner shelf.

SWPD Hydraulic Clamp Release Walkthrough
In the basement maintenance room of the South Water Police Department (SWPD), Simon discovers an industrial pneumatic gate held shut by a mechanical lock clamp. Releasing the clamp requires calibrating three interconnected pressure lines:
Target Threshold: Exactly 120 PSI across Lines A, B, and C
Examine the bulletin board next to the generator rack to find Maintenance Log #04. The memo warns that exceeding 130 PSI trips the emergency breaker, resetting all dials to zero.
Valve A → 35 PSI | Valve B → 70 PSI | Valve C → 15 PSI
Rotate Valve B first (the high-pressure secondary line). Next, bring Valve A to 35 PSI. Finally, bleed the residual pressure using Valve C until the green center indicator illuminates. Pull the large iron lever on the right side to disengage the clamp.

Island Clinic Radio Frequency & Garden Key Location
- Tuning Simon's Portable CRTV: When entering the triage ward in the Island Clinic, Simon's pocket CRT receiver begins buzzing with static. Switch the device to VHF Mode, tune the slider to 94.3 MHz, and twist the fine-tuning thumbwheel until the rhythmic audio clicks become audible (Eurogamer Walkthrough).
- Decoding the Broadcast Code: The synthesized voice recites four sets of chiming tones. Count the tone intervals: 7 chimes, pause, 4 chimes, pause, 1 chime, pause, 9 chimes (Code:
7419). - Retrieving the Community Garden Key: Input
7-4-1-9into the steel medication locker in the dispensary. Inside, pick up the medical supplies and turn to the corner shelving unit. The Community Garden Key is concealed on top of a terracotta flower saucer.
Frequently Asked Questions
What happens if the hydraulic clamp overpressurizes?
If total pressure exceeds 130 PSI, steam vents and the pressure valves lock up. Flip the red breaker switch located behind the chainlink partition on the left wall to reset the dials and try again.
Why can't I hear the radio transmission in the clinic?
Ensure you have replaced the blown vacuum tube in Simon's CRTV unit with the spare found in the clinic reception desk drawer. Without the working tube, the receiver cannot resolve frequencies above 88 MHz.
Do puzzle solutions change between game playthroughs?
No. Solutions are deterministic based on your selected Riddle Difficulty (Casual, Standard, or Hard). Solutions do not randomize on subsequent New Game+ runs.
Where is the Community Garden gate located?
Exit through the rear fire escape of the clinic and follow the cobblestone alleyway north towards St. Jude Church. The rusted iron gate on your right unlocks using the Community Garden Key.
