Always wondered why we didnt use those tap style wall iso's here tbh.
The vast majority of plumbers would probably love to use them but it would mean using flexi connectors to attach to them as they are designed for.
God forbid that the majority on here would want to upset the half dozen " Glitterati " on here that hate flexies.
Guess we will just be the sheep and do as we are told and keep those pesky foreign things out of our country.
