Washer on the Wrong Side of the Bulkhead

[aquaventions]

I hired someone to connect the bulkheads on my new tank since the piping had to be glued and since I have no plumbing experience.

Unfortunately, the fellow put the washer on the outside of the tank then glued the piping. The tank maker said we'd have to cut the piping in order to fix things.

Since The fellow has to fix this, he's also trying to figure out if we can set things up so that in the future the tank can be removed without having to cut piping.

What's tricky is that the return hole is in the corner and there isn't a lot of room for bulky fittings. Any suggestions?

The two drains and the one return in the bottom of the tank are all 1".

The only thing that comes to mind right away is using unions or using threaded fittings. I use threaded gate valves and bulkheads whenever possible in order to reuse parts and disassemble if necessary.

If there's not much room for fittings, try using a street elbow 90* fitting, that screws into the bulkhead. They take up less space than traditional fittings, and that way it will be removable as its threaded.

Here's an example of what I'm talking about:

use those on the end of your pipes to thread into the 90degree elbows
