PRESSURE RELIEF PIPEWORK
PRESSURE RELIEF PIPEWORK:
IMPORTANT: The pressure relief valve is a
safety device for the boiler and if activated
may discharge boiling water or steam
through the relief valve drain pipe.
Care should be taken when siting the outlet
pipe so that it does not cause an
obstruction or discharge into a public area
where it could cause a hazard.
• The pressure relief drain pipe (2) should be
at least 15mm diameter copper pipe and run
downwards away from the boiler and discharge
away from any electrics or other hazard,
preferably to an external drain or soakaway.
• Pipe (2) should be finished with a partial
bend, near the outlet to face the external wall
(as shown) to help prevent freezing.
