Typically if you go outside directly behind the inside unit you will probably see a white colored tube, this is the drain and if you have a wet/dry vacuum you can clear it with that. The actual drain can vary but it makes sense to exit and drain asap.
if the water is coming from the cooling coil on the furnace or blower package, that means the drain line is plugged. put a wet vacuum on the end of the drain line for a few seconds, that should **** out any residual sediment collected in the drain trap or drain line.
if your concerned about the water collecting on the line that is missing the insulation, that is only sweat from the humid air contacting the cold pipe (suction line)and doesn't pose any problem as long as the exposed line is outside. it would be a good idea to reinsulate the line to prevent the sweat and the refrigerant temp from getting too warm . the low gas temp in the suction line is what keeps the compressor motor windings cool and prevents it from overheating and burning up.
Don't let the dogs **** on the condenser (outdoor unit) the urine will corrode the fins and you'll start loosing capacity due to higher discharge pressures.
Bypass valve incorrectly set obstruction or dirty tank plugged line - lime or other! does cold flow into tank ok? Tank is split water going somewhere you can't see - this should be obvious.
There is not really anything to obstruct the flow normally so there would have to be an obstruction somewhere. Lime, junk, garbage etc build up . On my coach I have lots of pressure on the cold side so hot would have to have the same unless there is an obstruction into or out of the tank. If in the bypass position you have sufficient flow than the lines are ok and the problem or obstruction is in the tank itself. Drain the tank, leave the bottom plug out, open up the pressure relief valve. Turn on the water and see if you get a lot of water draining from the drain hole on the tank. There should be a lot of water coming out of the drain hole. If so that tells you that your getting sufficient flow into the hot water tank. If so your problem is the water getting out of the tank. Like a clogged return line or an obstruction from the water tank to the faucet. A dirty scale lined tank can do a number on tank water flow. Also check to see if the water is going somewhere else, your tank could be split and you just can't see where the water is going!
The things that you can check yourself are is the indoor unit level? Are the filters clean? The area the water is draining to free of obstruction? Is the drain actually draining? ----Get a cup of water and pour it over the indoor coil (please make sure the power is off first please) If the water does drain then it is prolly a bigger problem.
Prolly your unit is short of gas and need a refrigeration tech out to check. That it isnt ice-ing up but you would notice the performance drop.
this time of year it's either from your humidifier or if you have a high effeciency furnace it's because the water isn't draining where it's supposed to. you need to get to the furance or air handler and make sure the drain line is where its supposed to be.
