So i have to tear the tank down and move it. Plumbing will have to be removed too no way around it.

No way around cutting out the bulk heads and having to redo the plumbing right ?

Im guessing i can save the majority of it and use couplers to re connect.


Any thoughts ?

Looks like fun. Dang you didn't union around your bulk heads. Anyway you can twist it to break it apart?

This is me. Id find me a place where I could easily tie it back together with a short flexible piece. Cut it then tie it all back together with one little flex piece. I would really try to get the pipe broke loose from the bulk heads.

I cut PVC far enough away, and later add unions, that way the next time, its not such a hassle, and the bulkhead is not wasted.
After a few times cutting, I started using unions every four feet or so, around any corners, and close to bulkheads, saved me a lot of grief.
Also use threaded unions to attach plumbing to pumps, avoids the cutting and twisting.


 
Try use a heatgun where you have glued the pvc. I have had success with heatguns.
 
I couldnt fit as many unions as it would have liked
Probably could have added one closer to the bulk head on the middle drain and possibly save it but the right most one had very little room to work with.

I could probably fit one if i go with a 90° elbow on the middle drain instead of the two 45's

Also even with a union i doubt it would fit through the opening for the bulkhead. This one is a big deal just to slap on a new bulkhead and re plumb it with a coupler.


That middle one is the siphon. Each end is tee'd to a gate. Measurements need to be exact.
 
I did not buy solvent-weld bulkheads for this reason.

Looks like you will lose the big one.

Yes I always use threaded. I know it looks nice hard plumbed but I like to put a little flex joint in the mix as well. It doesn't make a drastic difference in flow.

I used PVC flex for the first foot, on the newest sump, so my pump wouldn't vibrate everything. It's too stiff to use just a foot.

The sumps where I used 9" of garden hose are quieter.

I try hard to keep a minimum of fittings and pipe for efficiency.
