The main floor drain in my Spa (concrete & pebble-tec) has two 2" ports on it - one on the bottom and one of the side. The one on the side is connected to the actual drain whereas the port on the bottom is plugged with a white, square headed Hayward 2" plastic cap (like this).
I've notice a leak in the spa. When it's full it could lose up to 4" of water a day, with the amount decreasing as the water level lowers (I assume less weight?) Using dye it looks like the leak is coming from the PLUG for the non-used port on the bottom of the main drain.
The water does not return to the pool, so it seems like it's just dissipating into the ground, which seems to make sense since that bottom port isn't connected... but I'm not sure.
I bought a new plastic plug and a tool to fit over the square to remove the old one. I want to replace it to fix the leak.
A few questions, if you don't mind:

A few questions, if you don't mind:
- Since this port was never going to be used, do they GLUE the plug in?
- If so, can I just use the tool to break the seal or will this likely crack the drain pot?
- If I get the old one out, do I need to use Teflon Tape on the new one? Both parts are plastic but it doesn't look like there could be an O-Ring.
