    We welcome the challenge. :)

    A 25,000 tap operation would be medium-sized producer here. We were at 1,200 taps in 2004. At 5,150 taps this year (2019). Headed to 6,500 taps 2 yrs from now...

    Hi John....you actually were right about the "prehistoric skeletons" part. DE is made up of mined deposits of diatoms, which are microalgae. https://en.wikipedia.org/wiki/Diatom Their cell-walls,...

    That should help establish the gradient a little faster (assuming nothing is frozen solid of course). It is similar to what we do when we clean (or change) pans. We put the frontpan contents in one...

    We try to get spouts out in the woods after it gets cold, but before there is much snow, and prior to tapping.

    Good advice. Cooling is necessary for most all pumps...just achieved in different ways, air, oil, water, etc. Put a bleed air valve in-line somewhere and use it to regulate the vacuum level and to...

    Yes. Shut it down for a little while to cool, shut off the connection between the pans, transfer the sweet from back pan to front, flood the back pan with water, then fire up again. Keep...

    Pushing sweet is more effective the higher the evaporator incoming concentration. Essentially what you are doing is changing the steepness of the density gradient in the evaporator. Take a look at...

    Very creative folks....just keep in mind to use food-grade materials for anything you use or make that contacts syrup.

    People use both approaches (leave the sweet or empty/finish in another container). Whatever works best for you. Note that if it is warm, you'll need to fire up every couple of days to boil briefly...

    Correction....DE is mostly (80-90%) silica, with varying amounts of aluminum (from clay inclusions) and iron.

    I suspect you are correct that the substance was built-up DE and defoamer (or grease)....

    Put them a good bit above the connection (dropline, spout) they are near, add a loop in the line, and put a tin can over them. Those things will help reduce the chances of failure, but you'll still...

    I agree with Dave. 1.25-1.5" would be better. Less chance of niter chunks clogging the pipe and stopping the flow.

    Although sanitary connections are more expensive, they are far easier to take...

    In terms of sanitation, longer than 5-10 minutes is not better (or worse). Shorter than that and the sanitation efficacy drops off (you won't have achieved the full effect). Longer than that...

    Might work well, at least for a while. Depends upon how much heat and steam it gets. Most of these small fans have a thermal cut-off switch, which shuts it off when it gets too hot. Over time the...

    Short contact time (as happens by pulling a solution in under vacuum) is fairly ineffective. Hardly worth (or not work economically) doing.

    You can either pump in a solution from the bottom, or...

    1:20 standard bleach (5.25% sodium hypochlorite) to water solution is recommended with a minimum contact time of 5-10 minute. Follow this with a copious rinse of fresh water. As long as you rinse...

    You are correct. What I was describing was the situation with a single mainline system. Conditions are different for a dual (wet-dry) mainline system. For at least the wet-dry component of that...

    Joe is spot on. Go with the 1" pipe. It is far more forgiving as well. You are always aiming to have AT MOST 1/2 of the pipe full of liquid during peak flows. That is under ideal installation...

    You're welcome.

    To continue the analogy, in the case of sagging lines, you've pushing and pulling the sap up and down a series of small hills. Takes energy to do that.
