I'm having "priming" issues and have checked everything possible to find the problem without success. I'm planning on installing a Vacuum Pressure gauge in either the inlet pipe just ahead of the pump itself, or screwing the gauge into the 1/4" drain located below the pump inlet basket.
It should be easier to just screw the gauge into the drain fitting than to install it into a PVC pipe, but for troubleshooting purposes, is one of these locations "better" than the other?
The gauges that I've found online all appear to have a 1/4" fitting. Is this the only size fitting available?
Thanks to any responders!
