Please watch this video for a visual walk-through on draining your Modpool:
To drain your Modpool, first remove the cap from the white tail pipe, located near the front bottom left corner of the mechanical room.
Screw a hose adapter onto this pipe and connect it to a 1.5”/2” fire hose, or if necessary even a garden hose should work. You can buy pipe-to-hose adapters at your local hardware store.
There is a valve with red tape on it towards the back of the mechanical room; open this valve to drain the pool.
When finished, close the valve again, unscrew the hose adapter and reaffix the cap to the tail pipe.
