Question about Flotec Plumbing

1 Answer

My 3/4 hp shuts off and on roughly every 2 or 3 seconds when using. i pumped some air into the pressure tank and it worked much better. but i pumped in a little more and now its every second. i'm thinking of draining it from just past the p. tank to the well to empty the p. tank(rusty water). pumps 2yrs old. or can the p. switch be adjusted? thanks

The switch is not the problem. The problem is the pressure tank. I am assuming you have a captive air tank with a bladder in it. The air pressure in the tank needs to be 2 lbs below the turn on pressure. Heres how to acheive that. Look at the pressure gauge on the pump and determine what pressure the pump is turning on. Next, turn the pump off and drain the pressure tank, then shut off the water to the whole house. If the pressure tank does not drain all the way, then you have a problem with the bladder in the tank. Once the tank is drained put the required amount of air in the tank. (if the pump turned on at 30 psi, then put 28 psi in the tank and if the pump turned on at 20, then put 18 psi in the tank) Check it with a tire gauge to confirm. Now turn the pump back on and see how it does. If done properly, your problem should be fixed. If it is a bad bladder, you will have to buy a new pressure tank.

Working pressure


Putting 60 lbs. of pressure in the pressure tank is not the answer.

First determine that the pump is working correctly, Open the drain valve and see if you get a good flow of water. If you do then OK, the pump is working. If you are not getting a good water flow from the drain valve, then the pump is not operating correctly - maybe a bad foot valve. Next open the drain valve and watch the water pressure gauge, and note at what pressure the pump kicks on ( that's the cut-in pressure), and when it kicks off ( that's the cut-out pressure). Most pumps are set to operate at 20-40 psi, or 30-50 psi. The cut-in and cut-out pressure is set by the water pressure switch.The pressure in the water tank has to be set 2 psi BELOW the cut-in pressure of the pump. That is, if the pump has a 20-40 psi differential, then the tank has to be pre-charged to 18 psi.

To pre- charge the pressure tank , the pump has to be shut off. The Tank needs to be emptied (drained ) of water. The air pressure is then set to 2 psi BELOW the cut-in pressure. If water escapes from the air valve, the bladder in the tank is ruptured, and a new tank needs to be installed.

So, first make sure the pump is working.
I WOULD RELIEVE MOST OF THE PRESSURE IN THE PRESSURE TANK TO ABOUT 20 PSI BEFORE CHECKING THE PUMP, AND PRCEEDING WITH THE PRE-CHARGE OF THE TANK.

Problem with pump?


The pump pressure switch should be checked to see what the ON-OFF pressure is set at. Typically the pressure switch is set for 20-40 psi, or 30-50 psi. The pressure tank should be purged as well. With the pump OFF, and the tank drained of water, the air valve on the tank should read approximately 2 psi below the "on pressure". So if the system operates at 20-40, the tank should be pre-charged to 18 psi. If water escapes from the air valve, the internal bladder in the tank is ruptured, and the tank needs to be replaced. A tire air gauge is used to measure the pressure in the tank after the water is emptied from the tank.. A tire air pump or a compressor is used to charge the tank. if a compressor is used, be careful not to over-inflate the tank, as this may cuase the bladder to rupture.

Shuts off when idling


You may have cooked the fuel pump. Or the gauge may be off.
I would check fuel pressure with a gauge and make sure you have gas in the tank. Anything less than a quarter of a tank is rough on the pump. It needs liquid gasoline to keep cool and lubed.

If in the past your system can build-up pressure up to 40 psi even if the supply valve is open and water is being used in your house, then your pump impeller maybe already worn out that's why its pumping capacity was reduced.

My 1/2 hp mastercraft pump cycles ever 3 seconds roughly. The pressure switch is set at 40-60psi. Should I replace or upgrade my pressure tank?


You might want to make sure you have proper air volume in pressure tank.


Shut down system. Drain tank. Fill tank with air via Shrader valve on top of tank until it has a few less psi than the low cut off setting. This will ensure that the tank still has water in it with some pressure still pushing it out when the pump kicks back on.


Without that cushion of air, the pump short cycles. ie every 3 seconds.....

My MAC 700 laboured to kick in to build pressure, and then finally quit. It won't turn on with the switch in the


All compressors dump a little air when they shut off, it's the air in the pump head and discharge tube. This bleed off should only last two to three seconds. If this pressure isn't bled off the motor won't be able to restart when the pressure drops in the tank becuase there will be too much pressure in the pump head for it to start turning again. If you have a longer bleed off or if the motor is struggling to restart most likely you have a stuck or broke check valve. It's the piece where the discharge tube connects to the tank. It's designed to let air into the tank but not back out so the pressure valve can bleed off the air in the pump. On rare occasions you can remove it and clean it out but usually they have to be replaced. You would need Makita Part Number 409004-E.

Motor "bogs down" at roughly 120 psi...almost stops


You suspect this unit as being a two stage because of the unusually high cut off pressure. It is a single stage and the motor really has a difficult task and is being pushed to the limits. to reach this pressure. We usually reset the pressure to lower setting ~~ say around 140. Your pump probably has a leaking intank check valve (brass fitting at tank) or leaking valve plate in pump. Simple tests : with pressure in tank unplug compressor from outlet and listens for air leak around pressure switch. As you unplug the running compressor from outlet you should hear air leaking from pressure switch for just a moment as air is let out of airline from pump to tank. If air leaks out till zero pressure then change the valve. If tank holds pressure then valve probably ok. Next test, with no air in tank and air filter removed, plug in compressor and feel intake port for strong suction. If the valve plate is bad, suction will decrease as pressure neers the 120 mark till the point of feeling that air is actually blowing out of intake. With good valve plate there will be strong suction untill unit reaches set pressure. If valve plate is bad also change the cylinder and piston ring. Good luck with your repair.

The pump goes on and off repeatedly


The pump should only run if you are using water. If you have a leak it will cycle on and off. If it only cycling fast when you're using water, you may need an expansion tank, sometimes referred to as a bladder tank for newer style. If you have a "bladder" tank , the bladder may be leaking and lost it's air charge. This bladder will have an initial air charge, and when the pump runs it will compress the bladder even further. When the pump shuts off the bladder is compressed. When you begin to use water, mainly low flow like one faucet, the bladder will begin to expand expelling the water from the tank until the pressure drops below that of the pump pressure switch. This makes the pump start and stop fewer times.

No more then 30 pounds of presure and wont shut off. Flotec water


If the pressure does not get pass 30 psi, then check for leaks along the pipelines and on the tank itself. An air leak on the top portion of the tank can cause the pressure not to trigger the pressure switch. Use soap bubbles to detect any air leak. Although a stuck pressure is not more likely the problem, check it also.

Pump spinning but not getting up to speed then shuts off


You have a pressurized system using a pressure tank.This is a case of an air logged pressure tank. Meaning there is more air than water in the pressure tank. The pressure tank must hold 2/3 water and 1/3 air of its total volume. Installed at the tank is the air volume control to take care of this proportion. Should the air volume control malfunction or becomes defective, the air-water ratio is affected. And then,
the pressure tank becomes either air logged or water
logged.
SOLUTION:
1. Shut the power off, and open the discharge line
gate valve to flush the water in the pipe lines.
2. Open the drain plug of the pressure tank to empty
all the water at the pressure tank.
3. Close the drain plug, and put the power on.
4. Start the pump, and set the flow control valve 1/4
open.
5. The pump will normally run.
