My A/C shut off
What to do after a water shutdown
If the HVAC system has shut off and the GraviTrip bottle holds water, the condensate drain has likely clogged or backed up. The shutoff did its job.
- Treat it as a drain or overflow condition. Don't just reset and restart.
- Call a qualified technician to inspect and clear the condensate drain problem.
- Empty the bottle A and refit it securely in the hanger.
- Gently pull the chain B to reset the switch.
- Confirm normal operation only after the overflow problem is corrected.
Emptying the bottle alone does not reset the switch.
Always finish by gently pulling the chain.
- Collection bottle: water here means a drain or overflow condition
- Chain: gently pull to reset after the bottle is emptied and refit
Keep the system ready
Maintenance & troubleshooting
Routine maintenance
- Test the switch and inspect the entire installation every six months.
- Inspect the bottle, hanger, chain, clip, adaptor, screws and wiring after any HVAC service.
- Keep the bottle upright and clean. Clean it with mild soap and water only.
- Replace the complete unit if any component is damaged, discolored, cracked, corroded, loose or unreliable.
Testing the shutoff (technicians)
- Add water to the bottle until the switch activates.
- Confirm the HVAC system shuts down, or that the selected alarm or control circuit activates.
- Empty and refit the bottle, then gently pull the chain to reset.
- Confirm normal operation returns.
| What you see | What to do |
|---|---|
| The system shut off and the bottle contains water | Treat it as a drain or overflow condition. Have a qualified technician clear the condensate problem, then empty and refit the bottle and gently pull the chain to reset. |
| The system stays off after the bottle was emptied | The switch hasn't been reset. Refit the bottle securely and gently pull the chain. Correct the overflow problem first. |
| The system didn't shut off during the functional test | Disconnect power. Check the mounting, chain routing or clip position, bottle seating, adaptor alignment and wiring, then retest. Don't use the unit until the test passes. |
| The bottle or hanger rubs, binds or hangs at an angle | The bottle must hang vertically and move freely. Reposition the chain clip and make sure the PVC and L-adaptor don't restrict the hanging assembly. See steps 4 and 5. |
| A component is cracked, discolored, corroded or loose | Replace the complete unit. |
FAQ
Frequently asked questions
What does the AC Flood Guard GraviTrip™ do?
It shuts off HVAC equipment when the condensate drain line clogs, backflows and fills the collection bottle. The weight of the overflow water trips a factory calibrated switch wired into the 24 VAC control circuit, and the system stops running.
How is it different from a float switch?
A float switch relies on a buoyant float rising with the water. GraviTrip has no float mechanism. It's gravity-activated, tripping on the weight of overflow water collected in the bottle. It's designed as a supplemental safety device, an added layer of protection alongside the equipment's existing safeguards.
Who should install it?
A qualified HVAC technician or licensed electrician. GraviTrip is for professional installation only, on indoor HVAC equipment with a 24 VAC low-voltage control circuit. Technicians can follow our step-by-step installation guide.
What equipment does it work with?
Indoor HVAC equipment with a 24 VAC low-voltage control circuit, where permitted by the equipment manufacturer. The switch is wired in series on the R control lead. It must never be connected to 120/240 VAC line voltage.
How often should it be tested?
Test the switch and inspect the entire installation every six months. Also inspect the bottle, hanger, chain, clip, adaptor, screws and wiring after any HVAC service.
Can the chain be shortened if it's too long?
No. The switch is factory calibrated to activate at a specified suspended load, and the full factory-supplied chain is part of that load. Never cut, shorten, remove links from, replace or otherwise alter the chain. Adjust the position with the chain clip instead.
Is it a leak detector?
No. GraviTrip is a supplemental safety device. It does not detect leaks outside the collection path, internal evaporator-pan overflows that aren't routed to the bottle, freezing, power loss or improper installation.
How do I clean the bottle?
Use mild soap and water only, and keep the bottle upright. The L-type adaptor is antimicrobial to help reduce algae buildup.
Where can I buy a GraviTrip?
Contact us for pricing and availability. HVAC contractors interested in installing GraviTrip can also ask about becoming an installer.

AC Flood Guard™ warrants to the original retail purchaser that the switch component of the AC Flood Guard™ GraviTrip™ Gravity-Activated Condensate Shutoff will be free from defects in materials and workmanship that cause switch failure for three (3) years from the date of purchase. This limited warranty covers switch failure only. It does not cover installation, wiring, tubing, drains, HVAC equipment, condensate overflow, false alarms, field labor, flooding, leaks, water damage, property, or any component or condition outside the switch itself. AC Flood Guard's sole obligation, and the purchaser's sole and exclusive remedy, is replacement of the defective switch component or product, at AC Flood Guard's option. This warranty does not cover labor, diagnosis, service calls, removal, reinstallation, travel, shipping, handling or other costs, except where prohibited by law.
This warranty is void if failure or damage results from improper installation, wiring, setting, maintenance, misuse, modification, cutting or shortening the chain, bypassing the switch, use outside product instructions or rated conditions, corrosive, freezing, or delayed activation issues, or failure to inspect, test, clean, and maintain the product as instructed. The owner and installer are responsible for proper installation, routine testing before use, regular inspections, monthly switch testing, and all required maintenance.
To the maximum extent permitted by law, AC Flood Guard™ is not liable for incidental, consequential, special, indirect, or other damages, including water damage, flooding, HVAC damage, property damage, mold, loss of use, lost profits, or costs arising from product failure, failure to shut off, false shutoff, installation, maintenance, or use.
To make a claim, contact AC Flood Guard™ Warranty Service at support@acfloodguard.com or AC Flood Guard™ at 4440 PGA Blvd., Suite 600, Palm Beach Gardens, FL 33410 within the warranty period. Proof of purchase, product/lot information, a description of the claimed switch failure, and return or inspection of the product may be required. Replacement does not extend the original warranty period. To the extent permitted by law, any implied warranties are limited to the duration of this limited warranty. Some jurisdictions do not allow limitations on implied warranties or exclusion of incidental or consequential damages, so some limitations may not apply.
