Sorry for the delay.

The answer is, it could work. But it also could blow out your filter or lines.

I used to try to explain to people how to solve plumbing and hydraulic issues like yours -- there ARE ways to install it safely. Unfortunately, I discovered over the years that virtually no one was able to follow through successfully on my instructions. And since they take a LONG time to write (and draw), I've quit doing it. Sorry.

Better bet? Use liquid pool chlorine OR bleach to maintain your pool water till you have a new pump OR close the pool.
