As others have suggested, you should conduct a risk assessment and consider the likelihood and severity of a flood or other fault condition. Another option I've not seen suggested is to install a float or level switch connected to an alarm sounder/beacon which would indicate a rising level and potentially warning of a pump failure. A friend of mine did ...
Most pump failures that I hear about are due to one of several causes. The pump runs on a regular basis due to poor drainage, high water table etc. Eventually it wears out and fails. Usually it fails in the middle of a flood. On other occasions it cycles very infrequently and it corrodes due to it being in a humid/damp sump well and rarely running. The other ...
If you frequently have power outages, a redundant system could well be worth the cost. This is especially true since power outages are common during storms, which could be a cause of rising waters. If you do get a redundant system, you'll want to get one that doesn't rely on the same power source as the primary. So you'll want a battery, or water powered ...
Only you can answer if it's "worth it". I would imagine if it did flood, the damage would be more than $400 and you'd be kicking yourself that you didn't spend that $400. If you die at 100 years old and it never flooded, I guess then you could say it wasn't worth it.
If the atrium is open to the sky, then it will always receive rainwater when it rains. Therefore, enclosing the space is the only way to entirely divert rainwater away from the space. This points to the general solution, changing the direction in which the roof system slopes (as a useful abstraction consider the roof system to include the gutters and ...
You should try UPVC as replacement of old one. Few months back, I bought water proof door from Fenesta. It will keep you away from all these issues. Also, the UPVC doesn't need maintenance and painting.
