However if I fit a double check valve in the flow to the shower,

This may be easier to fit -

Doesn't say if it's WRC approved. The regs on back siphonage are by & large
complete cobblers, but enforceable.

I once had a row with Mid Kent Water over a pressure washer. They wouldn't
allow a double check valve even though it was WRC approved. They suggested
that, if the 4" polyprop water main were turned off for maintenance, the
pressure washer could suck so hard that it would cause the pipe to collapse.
In their dreams.
