This was the first set initially.
Here is what I was taking about when I Plumb them together it was a tight fit. The tank to you right was the one that cracked. The one on the Left the bottom where the it goes back into the retun was leaking.
The is how the whole thing was set before the other tank was cracked.
Lesson learn never put to much pressure on a Tank that has thin glass and has a cut out whole in it...LOL....
