Radiators off, boiler switched off - can I turn the water on?

[Justice League]

The radiators were taken off and the boiler was switched off as was the water supply.

Would switching the water supply back on cause a leak? The only taps are the bathroom and kitchen which have their own stop valves. The toilet has not been removed.

If you disconnect the filling loop you should be fine.

The filling loop valve is in the off position ( ie 90 degrees to the flow) - or does it need a plumber out to disconnect it?

scott’s advice is sound as they quite often ‘let by’ even when in the off position. Disconnect the loop and then reinstate the water, observe if the loop is leaking - if it’s a tiny bit and it’s for a short time just use a catch pot. If worse or for a longer time then cap it off.

You won’t be able to use hot water though with the boiler/heating drained.

What sort of boiler is it? Do you have a hot water cylinder? if you have, use the immersion heater while the boiler is drained.

I think I was a vaillant combi from the other thread
