There are two reasons for this, 1st water is staying in the tank too long and should be drained more often and 2nd is what no one wants to here, the unit may be passing oil by the rings. We know everything starts to wear out. My suggestion to fix this problem is to install an oil water separator and capture the liquid that comes from the bottom of the tank. The oil will separate from the water and allow water to go to the ground while capturing the oil.

SOURCE: the drain valve is leaking air and will not allow

hand tighten with a little snug from a wrenck. you mat need to take it out and clean it. rust and sludge is probably your problem. make sure you are taking out the whole thing, not just the part you turn to let out water.

How do I drain the water out of my Husky air compressor model number 41004

Moisture that condenses inside the air receiver (tank) should be drained regularly and I have not yet seen a commercially produced compressor that doesn't have a tap or a plug at the bottom for the purpose.

I found a few Husky instruction books on the interweb (refer to yours if you have one) which says to access the drain valve.

Place unit on blocks to lift unit off of ground. Place suitable container under unit to catch water. Slightly tilt unit and turn drain valve counter clockwise to open. Place unit back onto blocks to drain water from air tank.

Air conditioner

There are several switches involved in an ac system . There is a high pressure switch that turns off the compressor if the head pressure is too high (blocked system-excessive gas qty) and a low pressure switch that switches off the compressor when there is insufficient gas -(leaking system)/ Next some systems do not work unless the blower and the ac switch are both on ( prevents ice forming on the evaporator coils from lack of air flow ). That is the electrical side of things . Next there is a TX valve that allows the liquid refrigerant to become gas in the evaporator ( producing the cold air) that can become blocked . There is a thermostat that is attached to the evaporator fins that will shut off the ac compressor when the cabin temperature has been reached. Next there is an air/dryer accumulator that can become blocked from moisture and dirty oil that will affect the operation. Well that is all the points that can cause problems.
How does it work . The system is full of refrigerant gas that boils off at a very low ambient temperature . The compressor compresses this gas and turns it into a liquid refrigerant in the condenser (In front of the radiator ) This liquid is pumped to the TX valve which releases the liquid into the evaporator coil and as this area is in vacuum from the compressor sucking the gas ,the liquid going from a liquid into a vacuum boils off from the heat in the car . This cools the air in the car . The gas is then sucked back to the compressor where it is again converted back to a liquid . As you can see ,any items that are not working properly will cause problems because the circulation of the gas has to follow a set procedure or the compressor will shut down. Best advice is -if you having ac problems then take it to an accredited ac specialist and have the system tested for gas and leaks.

Air releases from the bleader valve as soon as i turn the unit on and continues to releaseis this normal?

No you need to simple tighten the bleeder valve on the bottom of the tank. Its there to release moisture and manual says to drain after each use. I drain mine weekly if I've been using it. It prolongs tank life by preventing rust.

Spray is pulsing

this is usually caused by:

1. water in pressure tank of the compressor - clean the compressor holding tank
2. faulty valve in direct drive compressor (rare!)
3. dirty needle/gasket in the piece.
4. insufficient air flow

regarding 1:
stop the compressor,
open drain on separator and let all liquid out
allow pressure to drop to atmospheric
open drain valve on the tank and drain the content
on the compressor body find oil drain and drain oil
fill with new oil according to instruction on your compressor
close drain valve on the tank and separator
start compressor and check if problem is solved

re 2:
return valve is too difficult to change without specific model knowledge

re 3:
fill 1/3 (pint/500ml or less container)gun container with paint stripper and spray it directly to the sink or other container on full blast - WEAR SAFETY MASK, GOGGLES AND GLOVES! STRIPPER WILL BURN YOUR SKIN!
fill same level with water or solvent and run again, this operation should remove most of residual paints in nozzles and pipes.
check now nozzle for cleanliness and needle assembly, clean what necessary, use bit of vaseline when you will put it back together.
check for consistency of spray on piece of butcher paper with your usual paint. if problem solved - you are fine!

increase air flow... this actually should be done first.

for better instruction - please provide with model of the gun and paint used.

your comment and rating will be appreciated.

Machine wont go onto rinse cycle rinse indiactor flashes

It is possible that the machine does not start off the cycle because there are errors due to feedback from the inputs. For the program to start up the main program controller must initiate the INLET/MOTOR/DRAIN pump/ valve to open up and allow each function to be driven starting from the flow of water into the drum as also the drain valve to open to exit the water at the point of the program cycle. If this does not happen then the voltage at the valve/motor/pump must be checked or the fault relates to no voltage from the controller. This means the controller is a suspect.

If the water flows though the inlet then the flow pressure should be good, if not the inlet valve is bad or there is dirt in the filter. Also check the flow at the inlet of the water line. Once the water comes into the system the WATER LEVEL SENSOR - normally a pressure switch- must activate at the preset/chosen level to give the signal to the program controller to switch on the motor. What is most important for the motor to start functioning is that the door switch must be ON when the door is shut or this will be an error for starting the motor for rinse and wash.

Check this link to replace the inlet valve:

Finally after the wash the drain valve will be activated, the water is allowed to come in to rinse and then finally the dry spin with the drain valve/pump activated so as to drain off all the water from the clothes during the spin.

When finished with compressor how do I release the pressure

Gavin, There is usually a small drain valve on the bottom of the tank. You could just release the pressure through the normal hose, perhaps with a blow-gun on it, but this is not recommended because it will not remove the condensation that normally accumulates on the bottom of the tank. You only need to open the drain valve slightly. Good luck, Al K

I Have a Stanley air compressor Bostitch model APC-OL6-UK it is spitting brown liquid how do I clean this please

The brown liquid you are getting out of the compressor is water with rust in it from the inside the air tank. Somewhere on the bottom of your air tank there is a valve you need to open from time to time to drain the water from your tank. If you are getting rusty water from the air outlets you probably have a lot of water in the tank. If you can take the compressor outside, with pressure in the tank, where the water won't stain anything and slowly open the valve to drain the tank.
