Top Entry Immersion

[jaydebruyne]

I'm changing a top entry immersion tomorrow.. To date I've only done side entry.

I'm thinking I just need to shut off the gate valve on the cold feed (if it's not seized), run the lowest hot tap to drain pipework and then crack open the immersion - catching the excess with a wetvac.

Or is it best to drain the cylinder a little also?

Wouldn't bother draining the tank any Jayde. Just use the wet vac. You could always bung the tank to avoid the risk of the gate valve seizing in the shut position or letting by.

True indeed. Cheers Paul

Dont bung the vent though as you risk imploding the cylinder.

did the job today - had no choice but to use the gate valve as it was communal water services in a mansion block. Was fine though, closed and opened nicely - surprisingly!! Glad I had my wetvac though as the bugger was letting by - but all was well in the world thanks for your help fellas

I've seen one go, when a non return was fitted to the vent. So same as a bung.
