Why is there so much water in the air compressor line?

Leave the drain valve cracked open, (just enough so you can hear it hiss) during the day & continue draining it at night

The water in the air line is really just a function of the relative humidity. Do you live in a humid area? Is it raining often? All that matters. You may just need to install a larger drier or run with the drain slightly cracked open. For more money you could install a water trap with a timed drain valve, just like on big rig trucks with air brakes.

you can buy a timed drain valve that hooks in the bottom of the tank. most have a timer you can set for how long between blows and how long the blow lasts. for instance you could set it to go off every 2 hours for 10seconds to clear water out of the tank. you should also ventilate the room if its not like that already . if you keep the compressor cooler the water will condense better inside the compressor tank allowing the the timed valve to control the problem. instead of the water remaining steam and freely flowing down stream to the dryer. i hope this helps. good luck

The air is moist and when you compress it the humidity condenses and water forms. Do you drain the storage tank every night? It does sound like a lot of water but there's nothing you can do except maybe add another drier.

need more air compressor heads, so it can run at a slower speed.

As it is what you have is running very hot and hot air carries alot of moisture that, when cools down in the tank, the air drops the moisture. You have a drier in the pressurized air line?

No need to drain the tank. Just need to crack the bottom valve to push out the moisture. and then close it again. The rest of the air is dry.

Truckers air systems get moisture and find it more effective to just crack them to get rid of excess moisture.

Well you are doing things right. Depending on use and atmosphere of your location that might be the way it is. The only other thing is a inline dryer like a tractor unit has. It would pull water out and you don't have to drain it.

Basically,You have too much humid ambient(water in the air) in the compressor room or You have leave it running the whole night.

remember, is rainy season.

Nothing. All air has mosture in it and when it is compressed it condenses into water. Adding a smaller micron dryer might help but if you live in a humed place it is gonna get water.

we can't change the physical laws governing condensation , it sounds like you are doing all you can , in some of the water treatment plants i have worked in we had to put in multiple in line desiccators , read $$$ , keep doing what you are doing .
