Hi Richard,

Many thanks for your insight on this- most of the work is about complete. here is the layout I did. hopefully last question since you've had yours in operation. did you do any additional sealing other than using the O ring to the lower tank lids with the vents? any issues with leaking since these fill past the cap?
Just a potential for the upper to drain out if not a real tight assembly? can't appreciate your help enough, no other assembly quite like it I could find!

Hi Scott,
The system is working excellent, but I have encountered three issues:
- too much organic matter entering tanks, despite first flush filter: this is due to enormous amount of pine pollen (I'm in a middle of a forest) that passes by screen and the filter. It can be solved by increasing the volume of the first flush filter and installing screens on your gutters (not so much for pollen, but for leaves)
- upper tanks are easy to clean inside, but if you ever want to clean lower ones, you have to disassemble the system
- too low pressure to gravity feed drip irrigation, when water level in tanks is low: I have installed very small solar powered pump that solved this issue.
Not a big deal all three, I'm still happy with.

Many thanks for the reply and the insight! curious on the final piping method- looks like you were able to plumb it where all tanks work in unison as opposed to valve separating the upper and lower tanks? ideally I would like for the whole stack to work together to one outlet, this was the only post I could find with a 2 stack program.

Regarding tanks, I have decided to follow Mike Jay's advice from above. The majority of pipes are in place now, I need to add an outlet valve, air vents for lower tanks and to connect inlet pipe to the first flush T section. I'm lacking some parts for that, so it will take some time to get them, but as soon as they arrive, it will be finished quickly.

Then, the next step will be filling the tanks and checking for leaks.
