That stinks!
Yeah, we were supposed to get about an inch of rain and we got about 3” in maybe 12 hours. So, it’s not Noah’s flood, but it’s enough to flood parts of our yard.
That pump when working properly is great. It is rated over 8000 GPH @ 5’ head, and actual head isn’t even 2 ft. The 2” exit elbows and then feeds a 3” pipe. The flow has blasted out all the sediment in the 3’ pipe, so I for now went back to passive flow down the 3” pipe. The drop is only about 1 foot over 20’ of 3” pipe, so it’s slow, but ultimately it’ll get the worst of the flooding out. (There’s not more drop because typical water levels in the ditch after even modest rains don’t justify more drop! I was out there a few minutes ago, again: Not even 1/3 of the exit end of the 3” pipe is visible over the water in the ditch, and the water in the ditch has gone down a lot.
I’m gonna change clothes and pull the pump out: Maybe something is stuck in the impeller. Despite being rated to handle 2” “solids”, the impeller blade clears the housing by maybe 1/8”, and I’ve seen a small chip of wood jam it. I may need to put the whole thing in a screen “sock”.
Ah, the fun(s) of living on a flat, old flood plain, with clay soils.
Yup. Small, narrow wedge shape pebble stuck between impeller and housing. Apparently the water flow is “violent” enough to somehow carry such in there. Will HAVE to mitigate.
I think I’m gonna get a section of 2” flexible drain pipe. It occurs to me that when the ditch is full (or even the side yard) I could use this thing as a “blaster” to clear culverts and such. Use a section of 2” PVC or PE pipe as a “wand”, 1-1/2” if I want higher psi (but less flow).
