Pool pump problem: Cavitation sound in spite of no blockages in suction lines. Replaced many parts and replumbed with no success.

me id make a temporary suction line that could be dropped right in the pool (half union,suction hose with brick tied on end) this would easy test the underground pipes/valves for any spider cracks (air inlets) observe the output using the ole pump if no improvement then sorry that ole pumps gotta go

frequently on old installs I find that winter weather wasn't so kind to the plastic pipes and they develop spider cracks(tiny ) this provides a path to suck air into line

Function of deep well pump

A surface pump can only draw water from a shallow well, because suction can only lift water so high. A deep well pump is actually located inside the well, at the bottom, so it doesn't need to rely on suction for anything - the water is all around it. It can generate LOTS of pressure, so it can readily pump water out of a very deep well.

When our above ground automatic pool cleaner is contected(zodiac manta) our pool pump keeps filling with water and the vaccum does not move. The hoses are fine and we have changed the diaphram just...

I think you meant that the pump keeps filling with air. You may have an air leak on the suction side of the pump. If you turn the pump off, you should not see any water leaking out of anywhere, if you see any water drip near the suction side of the pump, you should consider that an air leak and repair it.

The problem you're having seems to be an air leak. when you connect the manual vacuum or if the system is running normally, there is not nearly as much suction that is created as when the zodiac is plugged in. The air is forcefully pulled into the system when increased suction is created.

Try replacing the lid o-ring and investigate any possible places on the suction side of the pump that could be a potential leak.

Hope this helps.

Need instruction and advice on how to hard plumb my above ground pool.

You have to find out what are your suction ports (for example skimmer would be one you probably don't have a main drain)once you have all suction ports located pipe separately back to pump and create a manifold so that you can isolate each suction port with a valve on each line then tie all back into a single line then into suction side of pump then pipe return side of pump back to the return ports of pool installing a valve as you come out of pump you don't have to separate these lines.

I need the manual of how to install the bath for the Comet 10 Jet Whirlpool 1500 x 1000 Bath. The Installer is having problem in getting the pump in the right position to work.

i don't have a solution for the manual however, the pump needs to be installed such that the bottom of the suction line going into the pump is 1/2" higher than the bottom of the suction elbow (coming out of the tub) thereby providing the pump with a flooded suction. This will provide the pump enough water to start pumping to the jets.

How do i change a power steering pump on a 2004 ford f 150 5.4 4x4

Follow this steps

The items you will need include basic hand tools, shop rags, gloves, drip pan, fluid suction gun, power steering pump pulley removal tool, power steering pump pulley installation tool, power steering fluid, and a Haynes manual.

Use a suction gun to remove the power steering fluid.

Position a drip pan under the pump and disconnect the high pressure line and fluid return hose. Cap the ends of the lines.

Loosen the serpentine belt and slip it out of the power steering pump pulley. Replace any worn belts at this time.

Remove the bolts and nuts that hold the pump onto the engine.

Remove the pump. Now remove the pulley from the pump. To do this, use a power steering pump pulley removal tool. If you don't have one, you can rent one from Advance Auto Parts.

Remove the nuts to detach the pump from the brackets.

Reattach the bracket to the new pump. Reinstall the pulley.

Bolt the pump back into place. Slip the belt back onto the pulley and retighten. Reattach the high pressure line and return fluid hose.

Now fill the power steering fluid reservoir until it reaches to the proper level. Now start the vehicle. Recheck the fluid and add if necessary. Turn the wheels left and right a couple of times. So that's it, you are done. Test the vehicle to make sure it functions properly.

Flotecpump runs for 5 minustes or less and shuts down due to over


With a 1-1/2 inch suction and a 2 inch discharge, you have no backpressure, and it's actually beneficial to have a working head. Try pinching the discharge valve to maintain a steady discharge pressure of at least 20-30 psig on the pump case. Tinker with the discharge pressure as required to balance the pump. As a general rule, the suction line is never smaller than the discharge line to prevent cavitation of the pump. A temporary move of pinching the discharge will compensate some, but it is better to increase the size of the suction line, if the pump will handle it. If the rated pump volume is low, you may also be trying to exceed it's capacity, and heat wil result in the motor.
If at all possible, convert the voltage to 220v as this will also make you more effecient and pull half the amps. Most pumps can be wired either way, and usually the diagram for swapping is included or inside the motor housing. Converting is easy.
Best regards, --W/D--

Drainout procedure incomplete

please clarify "The lower drawer does not have a similar problem." did the "but we lowered it by about 30mm as he required." make any difference? run this test: disconnect power to the unit. then find and disconnect the drain pump's wires (or connector). then apply power to the pump (I am assuming you have a 115VAC house supply) by a separate wire cord. run the pump on this cord until you see all the water pump out. if it does, then your timer is shutting down the pump too early. the water level sensor is mostly used for the other case during water fill only.
