THE HOSE FROM THE HOUSING TO THE TANK BURST, SO I TOOK THE HOUSING APART CUT THE HOSE AND REATTACHED IT (W/CLAMP).TURNED IT ON AND IT PUMPED TO ABOUT 40 psi AND JUST KEPT RUNNING WITH NO INCREASE OF PRESSURE.

Re: COMPRESSOR PUMPS UP TO 40-50 psi KEEPS RUNNING.
Most likely the pump is leaking somewhere, if the new hose is not leaking. Hoses don't just burst without showing signs or wear and tear, i.e. cracking and splitting. The pump was probably having problems, and this caused the hose to burst. Look for signs of leakage, and if you can't find them, the pump is shot.

The 34 psi of the pressure tank sounds high, but it depends on what the cut-in pressure is set at in the pump pressure switch. Typically the pressure switch is for 20-40 psi or 30-50 psi. To establish what the pre-charge of tank should be , you need to establish what the pressure switch setting are (i.e 20 - 40 psi , etc.) Run the water and watch the pressure gauge and note at what pressure the pump comes on. The pressure tank needs to be pre charged 2 -4 psi below that cut-in pressure. So if the cut-in pressure is say 30 psi, then the tank needs to be pre charged to 28 psi.
To pre charge the pressure tank, turn the pump off. Drain the pressure tank of water to relieve all pressure in the tank. Then check the pressure of the tank at the air valve. Set the pressure to 2 psi below what the cut-in pressure is.
If you adjust the pressure switch, say from 20-40 to 30-50, you will need to go through the procedure of re adjusting the pressure in the tank. I hope this helps....
I have seen the hoses develop a leak right where they exit the metal tube from the pump. The bad part is that you have to pull the pump apart to repair it. Here is a diagram so you can see what you have.
There is a check valve that is wired into the on off switch. If there are no air leaks when the unit is not running then it is normal. The other possibility is a leak where the rubber hose conncets to a metal tube inside the plastic housing.
You have a waterlogged pressure tank. To fix this problem, follow these steps:
1. Determine your cut in pressure by looking at the pressure gauge and seeing when the pump turns on.
2. Shut off the electric to the pump and shut off the main water to the house.
3. Drain the water from the pressure tank completely. You can do this by opening the drain at the bottom the the pressure tank.
4. With a air compressor and tire gauge (don't use pressure gauge on the pump) put enough pressure in the tank so that it is two psi less than the cut in pressure. So if your pump turns on at 30 psi, put 28 psi in the tank.
5. Turn the power back on to the pump and let it run till it shuts off.
6. Turn the water back on to the house.
7. This should fix the problem. If it does not, the bladder in the pressure tank is bad and the whole tank needs to be replaced.
This is a general fix without knowing your make and model of pump or pressure tank. This is a universal way of fixing this problem.
Hi, my name is John. Welcome to FixYa. The line that runs to that needs to be steel or copper or brass, as long as the line is rated for as much as the psi rating of the compressor. Thanks for choosing FixYa..John
I think I follow you... the adjuster over the large screw is used to set your tank pressure but also sets the cut-in/cut-off pressure. You have another regulator to control the pressure to and thru your hose but that doesn't insure that you won't exhaust the tanks supply and use more air than your pump can produce. It doesn't matter what pressure you set it at if your pump can't produce enough cubic feet per minute of air to keep up with your output. If your air use/output is within the pumps output, your idea will work just fine and you can set the hose regulator just below the cut-in pressure but Remember, even a little airbrush uses a lot of compressed air but sanders, grinders, sprayers and impacts use a Ton so don't try this without having somebody monitor the compressor periodically while you try it. It all depends on your air demand.
often the last ounce of gas in the tank has some crud in it. Get a can of carbeurator cleaner spray. Remove the air filter and squirt three short bursts of the cleaner spray into the air port and then start it. Keep giving it short bursts of carb. cleaner until it runs smoothly again.
If your pump is shutting off before it reaches it's max psi. then you need to adjust you switch. Under the black case there are two adjustment screws. One is the high\low adjustment, the other is high pressure cut off. The first will change when the pump turns on and off for your low psi setting and the high setting simultaneously. The second will allow you to raise or lower just the high setting. There should be a diagram under the black cap to show which is which. Adjust the high side only and just a 1\4 turn then run the compressor and see if that takes care of the high setting.
