In-Floor Winterization Boundary

In-floor systems become professional work the moment the air setup, zone isolation, or valve assembly behavior is not fully understood.

OWNER-SAFE
  • ✓ Identify the exact family, document zone behavior, and confirm the manual before shutdown.
  • ✓ Inspect canister lids, visible seals, and obvious pre-existing head or valve damage.
  • ✓ Photograph final positions and stored parts for spring restart.
PRO-ONLY
  • ★ Use compressed air when you cannot verify regulated low-pressure equipment and the correct zone-isolation sequence.
  • ★ Disassemble specialty valve modules or infer winterization steps from a different in-floor brand.
  • ★ Finish the job when damaged heads, unknown manifolds, or unclear air paths remain unresolved.
STOP NOW
  • ⚠ You do not have regulated air equipment or the manual procedure for the installed family.
  • ⚠ Zones do not isolate predictably, the valve assembly appears damaged, or water is not clearing the expected path.
  • ⚠ The next step would be guessing with pressure or relying on folklore instead of the real manufacturer workflow.

Winterizing In-Floor Cleaning Systems

Protect pop-up heads, water-distribution valves, and booster equipment with regulated low-pressure air and the correct manufacturer manual.

Start here

Record the manufacturer and model, then pull the correct manufacturer manual before disconnecting any plumbing.

  • ✕Do not use unregulated high-pressure air to blow out in-floor lines
  • ✕Do not use automotive ethylene-glycol antifreeze in pool plumbing
  • ✕Do not skip confirming zone operation before winter shutdown
1

Identify the exact system

A&A, Paramount, Caretaker, and similar systems share principles, but valve assemblies and recommended procedures differ.

2

Confirm operation before shutdown

If a head or valve is already damaged, winterization will not fix it and may hide the real problem until spring.

3

Blow out with regulated low-pressure air

The goal is controlled evacuation of water, not brute-force pressure.

Warnings
  • If you do not have regulated equipment or cannot isolate the zones correctly, hire a pool professional.
4

Protect the valve and canister assembly

The water-distribution valve is often the most delicate and expensive part of the system.

5

Use pool-safe antifreeze only where required

Antifreeze is a targeted supplement, not a replacement for clearing the water out.

6

Leave a spring restart record

The spring startup is cleaner when you know what was removed, drained, and stored.
