Can only use external power socket when pump is running
Had a water feature pump installed many years ago and as part of the work the electrician (fully qualified) installed an external power socket, with the RCD indoors (spurred off an existing indoor sockets: I think that's the expression).
Only problem with this is that RCD obviously needs to be 'on' (reset pressed?) which means the pump will be running. Trouble is there are a lot of times we don't/can't have the water feature working (puppy too interested so jumps on plans to get to it, or water is frozen), which means we can't use the socket.
Can it be changed to work independtly of whether the pump is on or not, or would it be better to have another external socket fitted (we are about to have an extension built).
This is a difficult one to answer as job would need to be seen to bw 1005 sure, but in theory yes it could be altered.
It sounds like the electrician did a basic job to keep costs down. In an ideal world the pump would have had a separate switch instead of being just controlled by the RCD. However it is possible to change the setup so that the socket could have power 24hours a day and the pump not be on aswell.
