How to isolate hot water circuit from boiler?

[berks1234]

Hi how can I temporarily isolate the hot water flow from a Combi, so that I can perform maintenance on a tap that has no service valve leading up to it?

Isolate the cold feed to the combi.

Turning you're stopcock off, usually under the sink should suffice.

I'll have to see if the Boiler has an isolation valve to on the cold feed.

If not, then I will have to isolate if from the mains supply.

I hope this won't do any damage to the Boiler.

I assume it will be better for my to turn off the boiler too.

I always do just Incase but shouldn't do.

use your mains stopcock less likely to leak afterwards than a isolator on a combi

Hi,

I used the isolater on that was placed on the incoming main.

Then I managed to get what I needed done.

Thanks all.
