This protocol is not primarily about “chemistry after rain.” Hail and high winds are physical events: flying debris can break things, leaf loads can choke skimmers, and a stressed circulation system can run with restricted suction or run dry. The goal here is to prevent damage, avoid basket overload and pump strain, and perform the right first checks before you restart filtration.

Flying debris risk (furniture, branches) Basket overload & suction restriction Pump strain / “don’t run dry” situations Filter pressure spike from heavy debris Cover damage and roller stress

Why hail + wind is uniquely dangerous for circulation

Storm debris is different from normal daily leaf fall. It arrives fast, in bulk, and often includes mixed material (twigs, bark, seed pods, grit, roof litter). That combination makes it easy to overload baskets and restrict suction. If the pump runs against restriction, you can get: weaker flow, air leaks pulled in, noisy operation, and rapidly rising filter pressure once debris reaches the filter.

1
Skimmer choke point: skimmer baskets can fill in minutes. When they clog, suction drops and the pump can struggle to prime.
2
Debris chain reaction: more debris → more restriction → less circulation → more debris sinks → harder cleanup.
3
Cover & hardware stress: hail impact, wind uplift, and flapping can stress covers, rollers, tie-down points, and surrounding fittings.

The smartest mindset: treat a storm like a “short, high-load event.” You win by acting early (prepping catch points), and by restarting in a controlled order (inspection → baskets → flow → filtration → chemistry).

Safety-first rules (the “don’t make it worse” list)

Do not restart equipment before you clear baskets.

Storm debris can fully block suction. Restarting into a blockage is one of the fastest ways to create priming issues and pump strain.

A
Don’t “set and forget” cleanup. If debris is actively arriving, short, frequent removals prevent a big clog later.
B
Don’t work near the pool during dangerous wind/hail. Prioritise personal safety; postpone anything that puts you at risk.
C
Don’t force stuck valves or lids. If something is jammed or cracked post-storm, forcing it can worsen damage.
If you suspect electrical flooding or damage: stop.

Wet equipment bays and damaged cabling can turn “a quick restart” into a hazard. Call a technician if anything looks unsafe.

Before the event: damage prevention & debris-control setup

If you have any lead time (forecast or visible front moving in), you can massively reduce equipment stress by controlling what becomes “flying debris” and by creating safe catch points for leaves and twigs. Think of it like storm-proofing your pool’s intake system.

Secure the area (reduce flying debris risk)

1
Bring loose items in or tie them down.
Outdoor chairs, umbrellas, toys, planters, even light pool gear can become projectiles in high wind.
2
Clear the “gutter-to-pool” pathway.
If roof litter and garden debris can blow into the pool, plan for a quick skim strategy during lulls.
3
Set up a debris net if you have one.
A leaf net / fine mesh net across the surface reduces the amount that sinks and later clogs baskets.

Covers can help, but they must be handled correctly for wind. Cover options and roller setups: Pool covers & rollers.

Prepare skimmers, baskets, and “catch points”

1
Empty skimmer baskets and pump basket (start with capacity).
You want maximum free volume before debris starts arriving.
2
Have a deep net ready.
Storm debris often includes twigs and bark that are easier to lift out early than vacuum later.
3
Know your “clean baseline” pressure.
After the storm, pressure trend is your fastest clue about filter loading.
4
If you have a leaf canister or similar, deploy it.
Anything that catches debris before it reaches the skimmer/pump basket reduces restriction risk.

Cover logic (hail + wind): when it helps, when it can hurt

A cover can reduce debris entry and hail impact on the water surface, but wind uplift and flapping can damage covers, rollers, and attachment points. Use the cover only if you can secure it properly for wind conditions.

If you can secure the cover
Cover can reduce debris and limit post-storm cleanup. Ensure it’s tensioned and edges won’t lift.
If cover flaps / lifts easily
A flapping cover can tear, stress the roller, and create additional hazards. Consider a surface net instead.
Roller & attachments
Check roller locks and straps. Avoid leaving loose sections that wind can catch like a sail.

For storm-relevant cover setup and roller handling: Pool covers & rollers.

During the event: what NOT to do (and what you can do safely)

Your personal safety comes first. Do not stand near the pool during hail or dangerous wind gusts. However, if conditions settle briefly and it’s safe, short “micro-cleanups” can prevent basket overload and suction restriction later.

What NOT to do

  • Don’t delay until everything sinks. Heavy leaf/twig loads become a vacuuming job and increase clog risk.
  • Don’t restart a struggling system repeatedly. Repeated starts with restriction can worsen priming and pull air into lines.
  • Don’t ignore skimmer sounds. A “gulping” skimmer can indicate air ingestion from low level or blockage.
  • Don’t push debris under the surface. Skim and lift out; don’t stir.

What you CAN do (only when safe)

  • Skim during calmer gaps to keep debris from sinking and loading baskets.
  • Empty skimmer baskets quickly if they’re filling rapidly.
  • Visually check water level (wind + rainfall can change it, and overflow can happen).
  • Note any obvious damage (cover tears, broken lids, displaced fittings) so you can address it before restarting.
“Don’t run dry” precaution

If baskets are clogging or the water level is unstable, the safest approach is to pause, clear restrictions, and restart only after a post-storm check. Running a pump with poor suction or air ingestion can create noise, heat, and mechanical stress.

Immediately after the event: the correct order (inspection → baskets → flow → filtration → chemistry)

Post-storm recovery is where equipment gets damaged most often — not during the storm. People restart the pump while baskets are packed, or they backwash blindly without confirming flow and leaks. Use this order to avoid suction restriction and pump strain.

1
Visual inspection (2–5 minutes)
Before touching equipment, look for obvious hazards and damage.
  • Check for broken glass or sharp debris in and around the pool.
  • Look at the equipment bay: flooding, loose wires, or displaced plumbing.
  • Check cover/roller condition and any torn straps or lifted anchor points.
2
Clear catch points (skimmer baskets + pump basket)
This is the fastest way to prevent suction restriction.
  • Empty skimmer baskets completely; remove twigs that can “bridge” and re-clog.
  • Clear the pump basket if accessible and safe.
  • Remove any visible debris mats floating near skimmers so they don’t slam back in.
3
Restore healthy flow (supervised restart)
Only now should you start the pump — and watch the first few minutes.
  • Confirm the pump primes properly and returns feel strong and steady.
  • Watch for air in the pump lid/bubbles in returns (possible air leak from restriction or seals).
  • Check for leaks at unions, lids, and valves once the system is pressurised.
4
Then filtration strategy (debris spike management)
Expect filter loading and pressure rise after heavy debris.
  • Monitor filter pressure trend versus your clean baseline.
  • If pressure climbs quickly or flow drops, clean/backwash earlier than normal.
  • Skim again after the first run — storms often “release” a second wave of debris.

Quick “first checks” checklist (tap to mark)

Use this to avoid the classic mistake: restarting into restrictions or hidden damage.

If the water overflowed / level is above normal

Storms can push water above normal level (rain + wind-driven surge). High level isn’t always an emergency, but it can change skimmer behaviour and wash debris into places you don’t normally see. Use this short logic so you don’t create new problems.

First: confirm safe circulation
  • Clear baskets so skimmers don’t choke as debris floats in.
  • Restart only after you can confirm prime and stable return flow.
  • Check that the pool isn’t pulling air intermittently (wind + sloshing can expose skimmer mouths).
Then: manage debris & surfaces
  • Skim repeatedly—overflow events often redistribute debris across the pool.
  • Remove large debris before vacuuming so you don’t clog hoses and canisters.
  • Once the physical cleanup is done, move into water-balance recovery as needed.

When to call a specialist (and why it saves money)

Storm damage is often “small but critical”: cracked lids, air leaks, blocked impellers, shifted valves, or filter issues that show up as weak flow and pressure spikes. Fixing the real cause early prevents pump strain and repeated wasted cleanups.

Pump won’t prime / keeps losing prime

Often a blockage, air leak, or damage to lid/O-ring. Repeated starts can overheat seals.

No flow / very weak returns

Restriction, valve misposition, clogged impeller, or filter overload. Running longer usually doesn’t solve it.

Filter pressure spikes fast

Media/pleats are overloaded by storm debris. You may need correct cleaning/backwash and a debris-handling plan.

Electrical concerns or water in equipment bay

Stop and call a technician—this is not a “trial restart” situation.

If any of the above appears, use: Pool equipment inspection & repair.

FAQ

1) Should I cover the pool for hail and high winds?
A cover can reduce debris and hail impact, but wind uplift and flapping can cause damage to the cover, roller, and anchor points. Use a cover only if it can be secured properly. Otherwise, a surface net can be a safer debris-control tool. Cover options: Pool covers & rollers.
2) Why did my skimmer clog so fast during a storm?
Storm debris arrives in bulk and often forms mats that block the basket openings. Once it mats over, suction drops quickly and the pump can struggle. Frequent short skims and basket clears (when safe) prevent the worst clogs.
3) My pump is running but returns are weak after the storm—what first?
Clear skimmer baskets and the pump basket first, then confirm valves are in the correct position. If pressure is high or rising fast, the filter may be overloaded. Weak flow + air bubbles can also indicate an air leak from restriction or seals.
4) Do I need to fix chemistry immediately after a hail/wind event?
Physical cleanup and restoring stable flow come first. Once debris is removed and filtration is running properly, then address water balance as needed. Use the post-storm recovery guide here: Water balance after storms.
5) How do I prevent a filter pressure spike after a debris-heavy storm?
Remove as much debris mechanically as possible (skim, net, clear baskets) before it reaches the filter. Then filter in blocks and watch pressure trend. If pressure rises quickly, clean/backwash earlier than normal. Filter guidance: Filter comparison.
6) When should I schedule a broader seasonal check?
If storms are frequent and you’re repeatedly dealing with clogs, pressure spikes, or inconsistent flow, a seasonal plan can reset baselines and reduce surprises. Seasonal services: Opening / winterising.
