Type of bulkhead (wet side + dry side) - threaded + threaded; threaded + slip or slip

Do you mean it wouldn't start threading, or it wouldn't actually tighten up ?

I have my standpipes just hand tight for easy removal and with tape on the threads they are easy to remove if needed. With them installed this way I get no leakage - my overflow box does not drain down when the pump is off

Does that help ?

gregzz24,

I've got 2 standpipes in my overflow for my herbie setup which are using 1" MPT to connect to the bulkheads a my return uses 3/4" MPT to connect to the bulkhead.

I have no problems tightening the 1" MPT to the bulkhead. However, the 3/4" is a real pain to get half the threads into the bulkhead. I've gone as far as trying different brands of 3/4" MPT ends.

If I thread it half way, will this be adequate or will it just develop a leak at a later date?

Thoughts?
