Can an automatic pool cleaner (a polaris) cause a leak?

I have an inground fiberglass pool and have been loosing about an inch of water a day. I read other answers and tried the bucket test and also marked the side of the pool with electrical tape to track.
I have noticed that my polaris has been shooting quite a bit of water out of the pool via splashing or getting stuck but the problem only began about a week and a half ago and I have had a polaris for years.
I completely shut the polaris off one morning before work just to test that theory. When I came home at the end of the day, the water level was fine! Then I turned the polaris on and after about an hour of running, the level dropped about a quarter of an inch.
I know water always flows through the polaris piping but could the surge in pressure after turning the polaris motor cause a minor crack to begin leaking?

Side note: my main drain line at the bottom of the pool has either clogged or collapsed but that has been the case for about a year and the pool has always looked crystal clear and maintained good water levels.
Any ideas or thoughts would be greatly appreciated! Thank you!

Answer
If the pool only leaks when the polaris pump is running it, it is almost certainly a break in the pipe between the booster pump and the pool. When the pump is running there is a lot mor pressure in the pipe so it will leak a lot quicker.
A leak detection company should be able to pin point where the leak is, and then a pool company can dig it up and fix it.

Look for wet soil in garden beds, etc. with the pump running.
Palm trees are the biggest culprit in breaking pool pipes.
