All of them have a low point drain.
Take a look at one of your exterior compartments where you can see the water tank or get access to your water pump.
Then look under that location and look for a hose that is stubbed down with a cap on it. Their may also be a few more hoses to drain your water tank and even one with a screen over it as a overflow for your water tank.
