Can you not use bulkheads that are threaded instead if slip so you can remove them?

Can you just use all threaded fittings from the bulkhead on so you can unscrew starting at the end an work your way back to the bulkhead from there?

Okay...thank you for the ideas. I don't know if I can incorporate them without the return lines really dropping into the viewable space in the tank badly. I will try to dry fit some different options and see if any can replace the glueing.

I'm afraid that I have no advice or suggestions to offer - just my empathy. I'd rather work with live electrical current than plumbing. Electrical either works or doesn't work - plumbing works . . . then leaks. I had to call my plumber brother in law to fix my multiple leaks. I hope that all goes well.

I just slip fit my 90s in. I applied pvc primer to the short piece of pipe in the 90 and the outlet of my manifold. this created the perfect amount of friction to hold them in tight.

For your leaky unions, have you tried silicone lube on the o-rings ?

For your enductors;
Are you going to use 3/4" enductors on 1" pipe ?
If so, what about 90s threaded on both ends
If your eurobrace is wide enough, you unscrew the enductors, then spin out the 90s
You'd need a spig x fipt reducer bushing and a close nipple for each fipt x fipt 90

If not, all that comes to mind is adding 4 more unions.
One on each side of the Ts and 90s that sit on top of your eurobrace.
It'll cost you some money to experiment with it, but a dry fit will show if you can wiggle them out or not with the outflow 90s in place

Absolutely! What I did.

Looks like this is a good solution
Quick and dirty and no more buying and chopping

So if I get this right...you just used primer? That made it gummy enough to hold tight...but loose enough that if you needed to break it, you could.

If this works....I will be dancing a jig tonight!!!

I thought I should do a quick update on the tank thread.

I've been desperately trying to prep my old house as a rental....meaning that the work on the tank has suffered...but some things have gotten done.

Water in the storage tanks, prepping to be transfered over to my sump and up into the display.

The plumbing from my overflow, just dry fitted so far.
