Of course what use is a build thread, if we don't show some of our mistakes and failures?
Was working on some of the plumbing under the tank today, gluing in the return lines. Normally I'm used to bulkheads and fittings having a lip inside them as a "stopper". Well I ended up gluing the pipe way too high into the bulkhead, and the rest of the piping won't fit inside the overflow!
By the time I realized what I had done it was too late, and getting that bulkhead off would be a PITA...
With every problem, there is always a solution. I ordered up an internal coupling to connect the two pipes. Now it's just a matter of waiting for delivery.
