Why is my chiller leaking?Updated 21 hours ago
If your chiller connections are leaking, don’t worry, this is usually a quick and simple fix! The system is designed to be 100% leak-free, so almost every leak we see is related to setup, usually missing gaskets or improperly sealed connections.
Before you start, we recommend watching this video for a visual guide on fixing leaks: How to fix leaks
Here’s a step-by-step guide to troubleshoot and resolve the issue:
1. Check gasket and o-ring installation
The most common cause of leaks is missing or improperly installed gaskets or o-rings. Every connection in the system, including the chiller ports, filter, and hoses, must have a gasket or o-ring in place to create a watertight seal. Plastic-on-plastic connections alone cannot prevent leaks.
What to do:
Ensure the white rubber gaskets are installed on the top inlet and outlet ports of the chiller.
Check that all hoses and filter connections have their corresponding gaskets or o-rings in place.
If you’re unsure, refer to the newly updated [Chiller Setup Manual].
2. Tighten connections carefully
Once gaskets are installed:
Gently tighten any black bolts or threaded connections. You can use pliers for extra grip on the bolts underneath the connection threads. Do not overtighten, as this can damage the fittings.
You can also securely fasten the hoses with the included metal clamps.
3. Apply Teflon tape if needed
If the leak persists:
Use a small amount of white Teflon (plumber’s) tape on the threads of the filter housing, drain valve, or other plastic fittings.
Only a thin layer is needed — too much tape can prevent a proper seal.
The tape helps fill tiny gaps and creates a better seal for threaded connections.
4. Check for condensation
Sometimes water appears near a connection but is not actually leaking — this can be condensation forming on hoses or fittings:
Secure hoses with metal clamps.
Confirm that water is dripping from a specific point; if not, it may just be condensation.
5. Replace worn or damaged fittings
If the leak continues after checking gaskets, tightening, and applying tape:
Inspect the hoses and fittings near the leak for cracks or splits.
Even small damage can cause leaks.

6. Still leaking?
If you’ve completed all the steps above and the leak persists:
Record a short video showing the leak and the fittings up close.

Summary:
The chiller is designed and has been tested to be a leak-free system.
Most leaks are due to missing gaskets, loose connections, or improperly applied Teflon tape.
Following the steps above almost always resolves the issue.
