28mm zone valve on 22mm pipework?

[mmiles]

Hi
My mum's zone valve on her heating has stuck open. I have a spare 28mm zone valve which I can fit for her. The valve that needs replacing is 22mm, so can I get an internal reducer to use the larger valve?
That way I wouldn't need to cut out any of the pipe which I think will be awkward to get to.

Thanks in advance.

You can buy reducing sets. Then you just have to cut the olives off.

yeah go for it, keep the fire brigade informed though

Easier / quicker to buy a 22mm valve.
Cheaper / longer to use the 28mm with adaptors.

Either way, the end result should be the same.
