The fitting on the side of the pressure switch is an unloader and should bleed air when the compressor shuts off, if it continues for more than 30 seconds then the tank check valve on the pump discharge line where it enters the tank is not closing off and needs to be checked or replaced

How to Install Master cylinder in 2001 Bonneville?

The new master cylinder should have bench bleeding instructions provided in the box with it, it should come with some plastic fittings that screw into the holes that the lines attach into and some plastic tubing. You screw the fitting into the holes and attach the tubing to the fittings. Clamp the master cylinder in a vise and fill the reservoir with fluid, put the tubing into the reservoir and actuate the plunger until all of the air is worked out of the master cylinder.You will still need to bleed the entire brake system when you place the new master cylinder on the vehicle as air will be in the system from taking the lines off, this will just reduce the amount of air.

Water will not flow into washer. I thought I forgot to start it, but it just runs through the cylce with no water.

The machiine has what they call a water level switch, or pressure switch. This switch has a tube that runs down to the side of the tub near the bottom connected to a box. As water fills the tub, air is forced out of this box and up the tube which in turn adds pressure to the switch. This is how the level and ammount of water is controlled. Sometimes sediment or what not can block off the airway keeping the switch pressurized thinking that there is water in the tub already. If not then the switch itself is bad. When you get a new one it comes with the new line as anyway.

When pressure switch is satisfied and turns off, air continuously blows out the side of the pressure switch

The check valve in the receiver tank is leaking. the check valve is located in the top of the tank where the copper discharge line from the compressor attaches. Shut off the power and bleed all the air from the receiver. Remove the copper line then remove the brass check valve. Once removed look in the check and make sure trash of some type is keeping it open. If trash is the problem clean and install. If not it will need to be replaced.

When it runs it sounds like an air leak from the engine and the tank does not fill. i do not hear air leaking when not running.

This sounds like the compression release valve is leaking. This valve bleeds the cylinder pressure to allow the motor to start without having the load on it. On this size compressor the valve is often built into the pressure switch. It is a little "pintle" type valve and you will hear hissing while unit is running but the opressure will not build up very much. When the pressure switch calls for the unit to run, the little valve closes with the switch. COntamination or other stiction keeping the valve form closing will cause the problem. You will find this near a tube that goes to the pressure switch. The switch itself hooks into the tank, but this little tube will connect to the cylinder head or the main tube from the compressor. Yours may look similar to ones at this site:
The valve is also commonly called the "unloader" valve.

I installed a new Pentair mini max heater 1yr. ago. I've used the heater about 10 times. I haven't used the heater the past 3 months and went to use it and the heater won't come on. I hear the blower...

An E04 can be alot of things.
If the fan is working, then the first thing to check would be the air/fan switch, or the air switch tubing itself. They installed the air switch tubing right over the burner tray so it melts and cracks quite often. This is one of the readons this model was discontinued.

The air switch is inside the cabinet on the right side behind the little metal box. remove the screws to access. The air switch is about 3" and round with a vinyl 3/8" tube coming out of it.
Also remove the top side panel on the right side. Now follow the air tubing from the switch to the blower in the side panel. Remove this tubing and inspect. Chances are there are som small cracks and things you will find. If this is the case, replace the tubing and try to restart heater.

If you did not find the tubing to be bad, then its your air switch. I would like to list the part number, but the model and BTU's were not provided above. Here is a link to the manufacturers parts and manuals list.

Hope this helps
BTW, a 1.5" gas line might be too much gas if its run all the way to the heater. As per the manual, 1.5" can be used up to 10 feet from heater, then bush down to 3/4". Gas pressure should be checked before and after the gas valve to ensure that the correct pressures are there. Pressure guidelines can be found in the above manual and should be followed strictly.

I have a air compressure with a square d 9013fhg44mix pressure switch. The problem is where the 1/4 air line goes, this valve leaks when ever the compressor is off. Once the compress is on it is off and...

The 1/4" line is very necessary and there are no adjustments on it. When the tank reaches full the pressure switch turns off the power and opens the valve to the 1/4" line to bleed off pressure from the air pump and feed tube so the motor can turn over the next time the tank drops to the kick in pressure. Every time the pressure switch turns the motor off a small amount of air should be heard coming out of the bottom of the switch for three to five seconds and then it should stop completely. If air continues to leak out of the switch by the 1/4" line, you have a bad tank check valve. The tank check valve is the brass fitting at the other end of the 1/4" line where the feed tube from the air pump goes into the tank. It keeps air in the tank after the pressure switch turns off the motor. Easy to replace, find the one you need for your model compressor.

How to replace a master brake cylinder on a 1989 oldsmobile 88 delta

First thing you need to do is bench bleed the new master master should have come with 2 plastic tubes and fittings.screw fittings into new master,fix tubes to fittings other end in to top of master where fluid goes.fill with fluid make sure the tubes are submergered in brake fluid for entire process.take a screwdriver and press plunger in rear of master.use short slow strokes to start you will see air bubbles in resovoir.slowly increase length of stoke watchin resovoir till no mome ready to install.Remove failed master,(loosen lines befofe removing mounting bolts)remove lines last.reinstall new master then remove bleeding tubes last install and tighten lines.Fill fluid replace lid,have a helper sit in car,loosen lines about half a turn.Have helper depress brake pedal slowly and hold down pedal untill lines tightened.when tight release pedal and repeat 5/6 times.fluid should come out of lines without any air when bled propperly.if failed master did not run out of fluid uyou should be finished.if pedal still soft/mushy will have to bleed a wheels also.use same proceedure but openening bleed screws not lines.may take many times to get rid of all air,you can see and hear the air exiting bleeders.keep an eye on fluid level while bleeding if u run out you are starting again

Craftsman Pancake Compressor loosing air while compressor is running. I tore it apart and there is a bolt with a pin sizes hole in it in the side of a brass fitting. What is this fitting for. It only...

That is likely the compression release. A pintle valve in it should close while the pressure switch runs the compressor. After the switch cuts off, the valve is released to bleed the pressure off the cylinder head of the compressor to allow it to restart without having a load on it.

When the pressure switch cuts off you should hear a woosh as it bleeds but it should NOT bleed while it is running. Take it apart and clean the seat. Be careful of springs that go sproing.

Compressor stops then leaks down to low setting

That little copper line is an unloading line, to bleed compressed air out of the compressor head so that the motor can more easily start the compressor. Pressor switch should be threadded into top of air tank, and the unloading valve is built into the side of the switch. When the tank reaches the high pressure setting the switch disconnects power to the motor and opens the unloading valve at the same time. The unloading valve should be connected to the compressor discharge line through a check valve with an unloading valve port upstream of the check valve. These valves are usually threaded into the top of the air tank as well. Sounds to me like your valve was leaking and someone bypassed it.

Kenmore 80 series overflow

The water level switch senses the water level in the wash tub. It does this through a plastic tube which runs from the switch in the control console down to the side of the outer tub, near the bottom . The tube is filled with air. As water enters the tub it also enters the tube. As water climbs inside the tube, it pushes on the air trapped inside and increases the air pressure. When the air pressure reaches a certain level, it triggers the switch. Inspect the air tube for kinks, breaks or damage. The tube should also be free of water. The tubing should be securely connected to the bottom of the outer tub and to the bottom of the water level switch. If the Tube is full of any water, remove it from the switch and replace it with a new one. Make sure that the new is correctly fitted to the switch.

The switch routes current from the timer control to the temperature switch and the water inlet valve when the tub needs to be filled. Once full, the pressure switch cuts the current and reroutes it to the motor on the timer control to continue the cycle. If the tube replacement dose not improve the fill performance, and it continues to overfill, replace the timer.
