    Same as a lot of things. It is great as long as it is installed correctly. Not installed correctly is an altogether different matter. We have a few hundred feet of 3" pipe installed as an air...

    Pretty typical in early season. Tap on the south might run some, tap on the north still frozen. End of the season it's the other way around...south taps dried up, north taps still running.

    You'll be quite happy with the upgrade. The lithium batteries last quite a lot longer than the Nicad batteries too. If you have other 18V DeWalt tools, there is an adapter to let you use the 20V...

    In lieu of or in combination with side ties, you can just do small turns on saplings periodically. This works well especially in places where crop trees are spread far apart. Don't go completely...

    Some will last 3 yrs, some don't. All depends how much sun exposure they get and how much stress they are under. They tend to get brittle and crack or break. They'd last several yrs in the middle...

    Yes, when you're cutting them in is a good time to tighten the lines up. One good hint is to install all the drops on the uphill side initially, maybe 6-12" away from the tree stem (depending on how...

    Were you aware of the plugging before you cut out the tees? Any visual indication without cutting into the line?

    Do a water rinse, then soap (RO soap) wash, followed by a rinse. If the musty smell persists, repeat, but add an acid wash (citric acid typically) at the beginning.

    These types of pumps are made for moving liquid, not necessarily air. The CFM removal of air is typically quite low. Thus any small leak will drop the vacuum level quickly. The same however is true...

    Yes, but the chlorine concentration can vary among different products, so I can't globally tell you what the dilution ratio would be. Depends upon the product you're using.

    3 years is about the time that clogging starts to be a problem. By bringing it in, flushing, and blowing/storing dry you've probably delayed the problem to a large degree. If you're taking it in...
