In a previous post I put a clear vertical tube in my garden. That worked, but only if I was in my garden and only if I remembered to look at it. It still wasn't ideal. What it didn't offer was a gauge. It was easy to tell if it was empty, but I couldn't really tell how close the barrel was to being full.
Anyway, I decided to use the same idea but expand on it. I got a section of clear tubing, attached it to a garden hose, and ran it vertically along a fence post.
|Front yard rain barrels which are attached to the drip irrigation that waters the garden.|
|Water level in the front yard barrels is lower than the back yard barrels.|
|The valve on the right connects the front yard barrels to the back yard barrels.|
|Back yard barrel level after it reaches the same level as the barrels in the front yard.|
This isn't a perfect solution. I still have a garden hose running across my yard. I'll probably end up relocating the clear tube to someplace else, but for now it's good enough.
I'm real happy with the fact that this allows me to get a few more days of irrigation in my garden without having to fill the barrels from the house water.
