| Per your replacement query
I would buy the new one first. Make sure the distance between the pipe stubs is the same. It looks like you are not going to be able to turn the water off at the faucet and will need to turn off all the water to the house.
This setup is very different than what we use in the US. Our shower valves are behind the tile. Most of the time we can repair them, but when we can't it is a lot more difficult to replace the entire valve assembly.
Yours looks like our very vintage wall-hung kitchen faucets. Those we remove by turning the nuts counter clockwise. The nipples protruding from the wall are always threaded pipe. Looks like yours are copper pipe with the adapters held in place by the set screws. Probably use o-rings for seals.
Let us know how it went. |
