The first water barrel (A) on my allotment is at the top of a slight slope and is fed by rain water gathered from the roof of my shed. I want to put in a second barrel (B) in a direct line (no bends involved) from the first barrel and down a slight slope. Both are fitted with taps, but I would always prefer to drain the water from the lower barrel B as it is a little more accessible. How best to connect these?
I have options to run a connection pipe from the upper barrel (A) to the lower barrel (B) as follows:
- Connect from top of barrel A to top of barrel B
- Connect from top of barrel A to bottom of barrel B
- Connect from bottom of barrel A to top of barrel B
- Connect from bottom of barrel A to bottom of barrel B
Which would be the best option? Or maybe there are other options that I not thought of?
Thanks for replies in advance.
