⚠️ Emergency Response: When You Notice a Leak
Emergency Response in 5 Steps
Close the main valve or network valve. Stop the progress of the leak.
Drain the water from the discharge valve. Caution: Water may be very hot!
Wipe with a dry cloth and watch where the water comes from.
Replace or repair the necessary part according to the guide below.
Fill early in the morning or late in the evening and check for no leaks.
5 Common Leak Points and Solutions
Tube-Manifold Connection
The most common leak point. Where the tube is attached to the manifold.
The silicone seal is old, hardened, or incorrectly installed.
Remove the tube and replace the seal or re-install it with silicone oil.
Tank Welding Points
Leakage from the weld seam of the inner or outer tank.
Crack, hole, or corrosion in the weld seam.
Professional weld repair or tank replacement is required.
Pipe Connections (Unions)
Leakage from water inlet/outlet pipe connections.
Loose union or deteriorated Teflon.
Disassemble the connection and tighten it by wrapping new Teflon.
Safety Valve
Water is constantly dripping from the valve.
System pressure is high (over 3 bar) or the valve is faulty.
Add an expansion tank or replace the valve.
Heating Element Cover / Anode
Leakage from the electrical backup heating element or anode connection.
The seal is old or the cover is not tightened properly.
Replace the seal and close the cover by cross-tightening.
How to Detect a Leak?
- 1 Wipe all wet areas with a dry cloth
- 2 Wait a few minutes and identify the first spot that gets wet
- 3 Mark the leak spot (with tape or a pen)
- 4 Detect small leaks by wrapping paper towels

Reach via WhatsAppFrequently Asked Questions
My system is leaking water, what should I do?
First, close the water inlet, drain the system, and identify the leak point. If it's a seal, replace it; if it's a weld, seek professional help.
Water is leaking from the tube-manifold connection, why?
The silicone seal may be old, hardened, or incorrectly installed. Remove the tube and replace the seal or re-install it with silicone oil.
Water is constantly dripping from the safety valve, is it normal?
No, constant dripping is not normal. This indicates that the system pressure is too high. Add an expansion tank or replace the valve.
What should I do to prevent leaks?
Check the connections once a year, replace the seals every 3-5 years, pressure should not exceed 3 bar, and install an expansion tank.
