When starting a vertical volute pump against a vertical rising main open ended with no valves from a wet sump will the hydraulic thrust ever act upwards? Conversely when pump stops could an upward thr

I'm about to install a gravity overflow from a 500 gallon catch basin which runs down a 140' drainage pipe into another Tank (already existing on a neighboring property) which then gravity feeds event

I've got some friends who drag race and they go through springs a couple times per season due to huge valve lift, high rpm, large heavy valves, etc..

I have been thinking pressure sensor but everything I have found is quite expensive packaged sensors. Any ideas on other ways to monitor depth or sources of something I can use for a sensor in a 500'

We had a situation recently where a 1000 hp 11.5 kV induction motor (full voltage start) was burned up because someone accidently tried starting the pump while it was spinning backwards.
