Can storm windows be made not to leak

We bought and had triple track storm windows installed to replace our 30 year old ones as the primary windows in our enclosed patio and were not informed that they didn't stop hard rain from coming in. We never had any problems with our old ones. Any suggestions on what to do to make them waterproof? We have to keep putting dry towels on the sills when it rains hard. Talked to the company and the manufacturer and neither had a solution for us.

Welcome to the forums.

A picture or two would help us visualize what you have there..... how-to-insert-pictures.

The sill expander on the bottom probably catches and holds water. Without slathering everything with caulk, making them impossible to remove in the future, I doubt there is a good solution. Storm windows aren't as effective as a primary window is.

The water is probably coming in through sill expander, however hopefully not overstating the obvious, but...

If the windows are not in the correct position they can let water in easily. The top window must be in the outermost track to overlap the lower inner window (middle track) to prevent water from entering there. The screen is usually in the innermost track.
