Re: home improvement turns into science fair projects?

For a little more local excitement, my adapter arrived today so I can connect my garden hose sprayer to my 3000PSI power washer....

This will either spray up higher than my trees, or blow up... :lol:

Full report later.

Re: Gentle persuasion over time

In anticipation of spring, I am working on some more precision tree cutting... Yesterday I dropped one of two trees on my cut short list that were stealing sunlight from a productive pecan tree in my far back yard. IMG_20200315_160647186.jpg The pecan I am trying to rehab is in the center of the pic...

Re: home improvement turns into science fair projects?

I am having to convince myself to stop trying to improve the float level switch.... It works (for now) and the 10 seconds of turn off delay gives it some hysteresis . The power meter arrived but with the pump only running for tens of seconds I don't get much to read... looks like 300+ W which isn't ...

Re: home improvement turns into science fair projects?

Day 2 of cybernetic sump pump control. I cannot hear it cycling on and off, but the crawl space is now dry, down to the float level, and I can see where water is coming out the end of the discharge hose over time. I do not know how many cycles the relay switching the motor is rated for. Apparently w...

Re: home improvement turns into science fair projects?

IMG_20200307_105110475.jpg The drama is slowly winding down for now... Yesterday the float level was set too low and didn't turn off... This morning I raised it up and inch and got it to turn off in a bucket, but down in my crawl space it perpetually short cycled as water kept flowing into the well...

Re: home improvement turns into science fair projects?

In a pleasant surprise the faulty float switch I returned for repair already arrived back... The service ticket says it failed the relay test? It looks like they sent me a new unit... it does not smell like the one I sent back. :lol: IMG_20200306_151314609.jpg This time I did a better job attaching ...

Re: home improvement turns into science fair projects?

The new bigger sump pump makes quick work of accumulated water... What used to take hours with the old 1/4 HP pump pushing water through 3/4" garden hose, now takes minutes with 1/2 HP and 1.25 discharge hose.... Good move. Twice the power, 2.8 times more hose section. Plus a better efficiency, I p...

Re: home improvement turns into science fair projects?

I am more concerned about smoothing of the display result, and not very optimistic... I expect it to at least be steady when pushing the full stream of water. Jumping around with partial flow may be all the indication I need. The new bigger sump pump makes quick work of accumulated water... What use...
