    Oscilloscopes Latest Enhancements

    Kar B, It would be great if you could be more specific with making the case for us car wash electronic troubleshooters & sometimes modifiers to supposedly never need a scope for some parts within our car wash equipment.

    Oscilloscopes Latest Enhancements

    Keno, I even notice a youtube where some oscilloscope - probe combinations can be used to function similar to a spectrum analyzer to detect EMI weaknesses within circuits that could contribute to the "dreaded" intermittent problems.

    Oscilloscopes Latest Enhancements

    I recently decided to revisit the possibility of investing an oscilloscope to hopefully help with troubleshooting the large variety of equipment we have. What I found that they are now much more affordable dollar wise in relation to their features. I have not invested in one yet ... still...

    Saving a few $$ with Zoro Tools

    Any thoughts on Temu for some relevant hardware items??? Other than possibly money going a bit too much to Mainland China. More direct a bit like Ali-Express ... possibly so less margin of profit to Mainland China for the exact same item from a much higher priced middleman. Of course, the...

    Customers trying to hack coin mechanisms

    Were they metal 3D prints? The various much more common composite plastic 3D print materials for sure would not work!

    Customers trying to hack coin mechanisms

    Something tells me ... the odds of a resulting jam is the bigger problem ... unless they are actually getting hoppers to trigger from a changer machine resulting in free money vs just car wash equipment activation. FWIW, on both our Standard ChangeMakers with short acceptors ... it has never...

    Spot Free Hookup

    If not too difficult to revive ... it could buy the operator time to shop around a bit longer for the best fit for him or her.

    CBK- Chinese Manufacturer

    Possibly, some weight on the decision would be the question of ... if their competitors are already using a large number of "Made in China" individual parts & components???

    Fleck 9500 water softener issues

    Since the 9000, 9100, and the 7000 Fleck valves are mentioned ... I am curious to know if the Clack valves run over $500 not including labor. Last spring we finally solved that same problem of leaking into the brine tank continuously. We opted +$$$ to replace any part that could cause the...

    Air compressor problem

    A few inspectors have lectured me about ASME on the HVAC side of my business ... maybe now I will pay attention a bit more! Funny no inspectors ever bother to look at the air compressor tanks that I have had over the years! With a local machine shop & a highly reputable sheet metal shop...

    Parker Regulator - Air Leak

    FWIW ... so far this one has been 100% for us for the last 6 months: https://www.harborfreight.com/14-in-nptf-mini-filter-58179.html Sometimes the quality of the overall reviews on a product can give a clue IMHO!

    Mobile phone theft tends to be very much on the increase ... so maybe that could be a consideration?

    Car Wash insurance…. Update

    Car Wash insurance…. Update

    I am tempted to get an independent certified appraiser "familiar with local market values" to appraise ... since some brand new insurance quotes are basing ... around 1 million $$$ to 1.2 million $$$ for both building & content. I am pretty sure the coverage cost would come in much lower! The...

    Questions about slab heat

    Earned kudos for 2Biz, I see by your photo that you did adhere to the 6 inch primary-secondary rule! I found an extra good visual simulation explanation on YouTube about the potential complication that some can avoid by paying attention to that 6 inch rule: (1) Primary-Secondary Pumping on a...

    Cryptotap Plus

    The tap process appears to a bit like the Sam's Club Gasoline fill up process that requires the use of a smart phone's camera on their displayed QR code that has been around for a few years & I have used many times from its beginning. When it worked 100% ... I did notice that it was a time...

    Questions about slab heat

    2Biz .... That 135 post thread that you started & finished back in 2012 was a real EPIC imho. The fact that your system has stood the test of time is (11+ yrs) also to very much to your credit. I notice with the Navien NFC-250/200H that we are currently putting in a residential retrofit in an...
