So I've searched and searched and can't really find the answer but on my overflow kits do I need to glue the various pipe connections that are inside the the tank in the overflow or can they just be dry fit since they will be under water anyway? I.E. Elbows, reduction bushing, etc.

your overflows can be dry fit since like you said they will be under water anyways.... mine are not glued and has been like that for years

Mine are dry fitted also, nice when you need to make adjustments. Fitting in my sump are also dry fitted.

Mine are also dry fitted together. It is done that because it is under water, and second if something gets stuck or if i want to clean them out i can take them apart to clean and put back together. plus with no glue on them you can adjust the stand pipes

Dry fit for in tank connections is fine.

As mentioned technically you can dry fit, however you do need to keep something in mind. When/if you do have a power outage for an extended period and if those dry fits are not 100% sealed, you can have that water go back into your sump. Many have more than enough room to take care of the 1-5 possible gallons that are back there, but I've seen quite a number of setups that are built to either overflow or come right to the top of the sump on power failure.

So again, a vast majority of the time dry fit is no issue. If you're cutting it reallllly close on remaining sump volume on power failure, take that additional overflow volume into consideration.

I used cement on the lower end of my Durso but the upper fittings are dry fit.

I dry fit but use teflon tape to get a good seal ........
