plumbing question - washing machine isolation valves etc

[philv]

Hi,

we've been looking into replacing and reworking some copper water piping in the kitchn.

I have an aversion to compression fittings.

I want everything soldered.

I can find all the various joints for soldering, but i am struggling to find isolation valves / taps for dishwasher / washing machine.
Are these always compression onky?

Thanks

Yes.

There is usually some kind of rubber/sliicone O ring or seal in the valve which would be damaged by the heat of soldering.

Even gas isolating fittings are compression.

Compression fittings are reliable if fitted correctly.
