What is a good range of water height for a sump pump?

Well, about a year and half later still running fine.
I did pipe the output through some PVC pipe I had lying around. Experimented on bending it with hot sand which worked fairly well. It was neat to ~ 3' of 1.5" PVC become like a thick soft rubber tube.

Because not only our HF furnace drains it's condensate into the crock but so does the crain for the hot water heater wich gets blown down monthly bedacuse of the minerals in our water that collect in the bottom of the HWH as well as the blowdown on the intermediate glass tank where our H2O2 mixes with the raw water and precipitates off the sulfur dioxide, the blowdown valve also dumps into the crock. Consequently, I set my sump pump on a 1/2 cinder block in the crock so the blowdown 'effulent' don't foul the pump. Every couple years I have to pull the pump and clean the soilds from the bottom of the crock, a messy but necessary task. I keep the float level so the water in the crock is about 4" from the top at all times. Benefits of living in the country with well water I guess.

I often wonder if people ever drain their Hot water heaters. They all accumulate sediment in the bottom.

Mine gets 'blowndown' monthly, same time I change the Cumo industrial filter element. I run 5 micron blown melt cartridges in it. Least we don't need a water softner.
