noisy hot water (from immersion) All aspects of plumbing questions and answers, help, tips and information

[adele]

When I draw hot water from the immersion, there is a very loud continuous noise (a lot like a ship's foghorn). This can go on for several seconds, then stops. I do not have this problem with cold water. Can anybody help? Many thanks

Hi Adele,

Is your water tooo hot ? if it is turn the thermostat down - the noise will reduce/stop!!
