Why not get a threaded reducer for the top of the "T" and then your theaded cap? The cap is only for adjusting your air to the pipe. Looks like 1-1/4" pipe? Get a 1-1/4" to 1" threaded reducer change your cap size down to 1"?

Or just leave it all not glued. Get a slip cap. With 3 down pipes you will likely sell the tank before you have to service them. There is really no need to have it glued, if it leaks it will just leak back into the overflow and not your floor. Obviously glue below the BH.

What kind of servicing do you think your going to need to do? If something gets caught in the pipe, it will likely be at the valve which I assume will be partly closed. You have true union valves so you will be able to disconnest there anyway.

So I'm going to do as Parkinsn suggested and get rid of the threaded cap and just do the slip cap. This will save me an inch; which is A LOT!!

Also I will probably not glue it so if I ever need to take a peek down there I can.

For the person that asked why I have valves plumbed to every standpipe it's so that I can test the fail safes. I will be able to create a scenario where if one pipe fails the other two will work. If two pipes fail I can safely rely on the emergency pipe. it's just so I can create different scenarios and make sure everything is working as it should. Peace of mind!
