I have decided to add a pressure relief line by adding a 3/4" PVC valve to extension stubout> and recirculate flow right back into the reservoir. By doing this I will relieve pressure from the sprinkler manifold and lines.

1. stub out to a T...

2. on the downside we stub out to a 3/4" PVC valve. (adding this valve will allow me to open/close it as much as I need to relieve pressure off the pump and enable me to use my sprinkler heads without bog down of pump motor.

3. Stub out to another T and we now have a waterstation for potted plants or filling water vessel(Special Feature #2)...Notice downpipe for pressure relief valve.

4. I had to move downpipe inside of support frame and I 90 stub 90'd over to final splashpipe.

5. Here is what final system looks like...Notice plants in res on left (When original system failed), I needed to move these to bigger res for final veg/sexing...so, you see, I already am using 'Special Feature' #1 :smokin:

...On the middle res...I have shown a line that could be a drip line, then another hooked to sprinkler head thru the top...Just to illustrate the versitility
of this design...

...I will be testing the newly re-designed system tomorrow night...Stay tuned.
...Same Bat-time...Same Bat-station...Peace. The madness is draining out of me now...I must retire to my :smokin: study..................
