A: If the water is leaking from the clear tube beneath the heater can assembly then you will need to replace the PRD ( Pressure Relief Device TRITO - 83301330 ) -
If the leak is coming from between the copper & plastic part of the heater can then you will need to replace the heater can assembly.
If the leak is not coming from any of the above then will need to ascertain where the leak is coming from before ordering parts and contact our technical support via our technical forum via the link provided - http://www.showerdoc.co.uk/forum/phpBB2/
