I'm looking to see if there is flow in the line of a 1 1/4" and 1 1/2" PVC
pipe. I'd like to check to be sure that if a pump is running that there
is
Flow in the pipe. So the flow will be more than just a simple faucet on.

Any Recommendations?

Thanks,
Scott-



There are plenty of companies that make flow switches, but I'm not sure you
can find something in a consumer price range. Try a local plumbing supply
or two to get an idea what's available and how much they cost.

A quick search on google for "Cheap liquid flow switch" came up with this:
