FAQs - Freezing Copper Pipe for Repair
Is pipe freezing safe for all plumbing systems?
Pipe freezing is safe for copper and mild steel pipes, provided they are in good condition and meet standard wall thickness. It is not suitable for plastic pipes.
How long does the ice plug last?
A properly formed ice plug can last 30 to 60 minutes, giving us ample time to complete most repairs. We monitor continuously and re-freeze if needed.
What pipe sizes can you freeze?
We can freeze copper pipes from 8mm to 54mm in diameter, covering most domestic and commercial systems.
Is there any risk of the pipe bursting during freezing?
No – when performed by trained professionals like SpeedyJet, freezing is controlled and precise. We avoid over freezing and use pressure monitoring to prevent stress.
Will I need to shut off the water supply?
In most cases, no. One of the biggest advantages of pipe freezing is that it eliminates the need to shut off your building’s water system.
Can you perform freezing on heating pipes or radiators?
Yes. We often use pipe freezing to isolate radiators, modify heating systems, or replace valves in central heating loops.
What if I have multiple pipes that need work?
No problem. We can freeze multiple points simultaneously using dual-freeze kits, enabling complex repairs across systems without draining or flooding.
