I think there might be quite a lot in that last sentence, Charlie. I'm a
bit concerned that the OP is hearing about people who haven't touched a
tank
in 15 years

If it's working and not causing any problems why should it be interfered
with?

Those who have such working installations are confident that they don't need
interference for any reason.

The OP has said the previous owners told him it was emptied annually. That
doesn't even begin to imply that it needs no interference. How *often* is
his question.
