    The difference is you can enter your Kw/hr rate into it and it will calculate cost and show it as a live updating number. SHows cost per day, week, month, year and Total cost since plugged in, using the build in time since pluged in counter. And there are several other measurments.

    Re: Harbor Freight 1" Clear Water Pump test and review

    Overall it's a cute pump and pumps alot of water out my hose, its quiet without prime. When running and primed properly it makes a med-to-hi pitched matallic sound, kind of anoying. My first one went bad after one use. Harbor freight is intersting, lots of good deals but the defect rate can be high on some things, still their prices are killer, and a little inconveince is probaly worth it especially in this economy.
    Take note it can't run at all with any air in the pump chamber it's particular this way, and the manual specificaly says you will damage the pump if it is run with out priming first. So a check valve is pretty much mandatory unless your water line is above the pump itself.

    Re: Harbor Freight 1" Clear Water Pump test and review

    I bought one of these last year, for testing purposes only. Have an inground hot tub, who's plumbing was completely cut off. Needed to put some pressure behind it to see if I had any leaks. It did what it needed to do, and we went ahead and hooked the hot tub back up.

    HF is good for generics, or one-time use type of things. Zip ties, clamps, etc. If I buy a power tool, or anything else mechanical, I'm convinced that it won't work for continual use.

    This little pump has found another job, though. My brother does competitive smoking/barbecuing, and I engineered a setup that involved this pump, an old laundry sink, a used car wash detergent barrel, some PVC, and a shower head. Running water when there isn't any to be had.

    I have learned that if you disconnect this pump for a period of time, you better fill up the impeller housing with WD-40, or it will rust solid.
