If the RCD has persistantly tripped with a full load on I would replace it anyway.
Isolate and megger every circuit, it could be a bit here, a bit more there, adding up.
Pond pump is a good suspect.
Using one RCD foe everything is always a problem waiting to happen.
There was a criminal who used to find houses with an outside socket, trip the mains, which turned off the alarm, and return a few days latter when the batteries had failed to rob the house. Most alarm batteries are not changed frequently enough, they lose charge quite quickly when not being topped up.
