over flow tank

[rayi]

I had two runs this year that over flowed a 200 gallon poly tank. Is there a low tech way to connect two tanks so if one gets full it flows into the other. My sugar bush is as flat as a pool table so one can't be lower than the other

Can you connect the 2 drain ports together? If so just T off that line for you feed line.

I never thought of that. I'll have to give it a try when the weather cooperates which may never be in my life time

If you connect the drain ports, you may also need to have a vent at the top of the second tank to let air out as it fills up from the bottom.

What shape are your tanks? If you could install a bulkhead fitting near the top of the 1st tank and plumb that to the second tank, the first will fill to the highest point in the line coming out of tank 1 and flow to tank 2. Make sure that high point is lower than the tank top on tank 1.
