Question about Plumbing

1 Answer

I have a 3/4 h.p. 4'' sub. pump. when the holding tank level drops enough to allow the float to drop and open the valve to allow well water to enter the holding tank, as soon as the pressure drops enough to kick on the well pump idrops to about 12 pounds of pumping pressure . it will pump at this pressure for a bit then the pump shuts off. it will restart in a min or so then kick off again until the holding tank is full again. is this normal? the shutdown seems to occur at the pump as i have checked the vmotor control box and it appears to still have power going out of it when the pump is not pumping.

The control box is always connected to the power
supply, that why it got power even the pump is not running. However, it does not consume much energy
as when the sub. pump is running. The operation of your pump is fully automatic. There's liquid level controller inside the well and a water level controller (float switch) at the holding tank. I believe there's nothing wrong with your sub. pump. Everything is
normal. If the control box senses abnormality, it
will just shut the sub. pump off. Just send in your e-mail if you need our assistance. God bless you.

Toilet Flapper drops too soon and causes incomplete flush. Replaced with new red Korky, and adjusted chain tighter AND looser.

Try adjusting the water level in the tank. Most flappers close as the water in the tank flows out to a certain level. Try allowing more water to come in to the tank. I doubt the weight of the chain has any effect on it closing too early.

How to adjust a toilet

  • Your toilet tank may simply need a good "tune-up." Here are some adjustments you can make.

  • Refill valve. If your tank has a conventional ballcock refill valve, the water level is adjusted by bending the float arm. The level should be high enough for complete flushes, but the water should not be to the top of the overflow pipe. Your tank should have a colored or molded water level mark. It should never be set so low that the bowl does not refill with trap sealing water. The rule of thumb is to set the water level about 3/4" below the top of the overflow pipe.

  • If the float rubs on other parts, simply adjust the float arm sideways. If the float lacks buoyancy, unscrew then shake it to determine if it is waterlogged. A waterlogged float should be replaced. The float arm can also be replaced, if needed.

  • In tanks using modern plastic refill valves, the tank water level is adjusted in other ways. If your tank uses a hand nut, turn the nut clockwise to raise, or counterclockwise to lower, the water level. Or, your tank may have a sliding pinch clamp on an adjustment rod.

  • Flush valve. Replacements for a flush ball and its actuating mechanism are available, but it may be possible to stop a leak with minor adjustments. Check the following mechanisms before purchasing replacements.

  • See that the guide arm is centered directly over the seat. The guide arm should drop the flush ball directly into its seat. If the flush ball is not seating properly, make the adjustment shown.

  • The guide arm should allow the flush ball to rise enough for a complete flush. If not, raise the arm. Be careful that it isn't too high–then it will prevent the ball from closing completely.

  • Check that the upper lift wire pulls the flush ball high enough. To adjust it, simply bend the wire for a higher or lower lift.

  • The lifting hardware on a flapper-type flush valve should raise the rubber flapper to start a flush, but should not hold the flapper up off its seat. If this is occurring, the hardware is adjusted too short. Some types allow you to slide the flapper itself up or down on the refill tube to ensure that the flapper meets the valve seat squarely. The lifting hardware and flapper height adjustments are the first things to check when flapper problems arise.

  • Refill tube. If the bowl-refill tube is out of place, water is routed directly into the tank, rather than replenishing water in the bowl. When this is the case, you will likely hear splashing sounds during tank refill. The refill tube should aim directly into the overflow pipe but should not reach below water level. If the tube extends too low, it will siphon tank water silently away. Fix it by repositioning as shown.

  • Defective refill tubes on some valves can be replaced with new plastic ones. Simply place one end of the plastic tube over the serrated plastic lug on the body of the valve, and place the plastic holder in the top of the overflow pipe.

    Water runs in the toilet off and on continually?

    Either the bottom outlet washer or the inlet valve washer needs replacing. It is a common condition, and if unsure, call a handyman in. An expensive plumber should not be needed.

    What makes the gas needle stop working-

    make sure you hooked up the wiring to the tank float sensor. if the wiring is intact, it's possible you jammed the float during handling. this will require dropping the tank again (after emptying it and allowing vapors to dissipate), removing the top access plate, and physically checking for freedom of movement of the float assembly. Use a multimeter to check the resistance as the float moves, should give variable reading as the float travels. reassemble, ensuring to seal the top plate thoroughly. test float movement again, by filling tank with water and watching the meter. drain tank and allow to dry completely. reinstall wiring and bolt the tank back into place.

    Gasoline leaking

    Pull the spark plug wire off the spark plug. If poss turn off the gas supply from the tank or have a container large enough to hold the gas remaining in the tank and drain tank. Small bolt or screw hold the float bowl on the carb must be removed and bowl may be a little tight so tap very gently on the bowl on one side then the other to loosen and remove bowl. Needle valve is poss being held in the open position by a small piece of dirt or rust and so the gas supply in constant and the gas is flowing out the vent.. diff mfr's diff setups. You must have patients with this float and valve removal. The float usually has a straight dowel holding it allowing it to pivot so to push up to close and down open the valve. gently remove the pin dowel and the float and needle will be free. You can then lower the float and needle. Be careful not to lose the spring of any parts. The parts are small. Better look long and or take a macro pic to remember how it all looks before you take apart. A small copper wire pushed up through the hole where the needle came from will usually dislodge the dirt. Or spray carb cleaner and allow the obstruction to drip out of the valve seat. Reassemble by placing the needle valve and float back into their rightful places. Check the movement very gently up and down. The closing of the valve takes VERY little pressure and you must never push with force. The float lever touching the bottom of the needle can bend or break. This is calibrated to the gas level required for normal ops. Now look at the inside of the bowl. Make sure there is no dirt of build up that will later come loose and cause this prob again. Carb cleaner works well with a rag to clean the bowl inside and out. Clean the outside edge and area so as not to push dirt inside the bowl when reinstalling the bowl. if there is a diff in height to the bowl then the short or shallow portion will be placed at the hinge point of the float. This will allow the float to drop to the open position and allow more fuel to enter the bowl. Snug the bowl securing bolt and make sure the oring or gasket was still in tact with the bolt and bottom of the bowl. reattach the gas line and pour a small amount of gas in the tank just to get the unit started and not so much incase the leakage is still there. Place the plug wire back on the spark plug and try it out. ALWAYS remember gasoline is very flammable and so be sure no sparks or flames are near. I advise doing this outside the garage and have a fire extinguisher very close because fire with gasoline get out of control Very quickly. Nitrile gloves are a wonderful thing too when working with gasoline too. Good Day!

    This is not a rider mower its a push mower. I pump bulb engine starts and then quits

    when this happens, the engine only runs long enough to consume the gas you manually put into the carb. The engine dies because the main jet of the carb is plugged or there is water in the fuel system. repair by dumping old fuel from tank, then remove float bowl on carb. this will drain remaining fuel in carb and give you acess to the main jet as well. Main jet will be located in the protruding part of the carb that sets as the lowest part in the float bowl. locate the jet either on the side of this protruding area or set into the bottom of the protruding area. use a thin wire like a guitar string to run thru the small hole in the center of the jet. then squirt a little wd-40 thru the hole and check visually to make sure the jet is clear. there also could be a problem with the float or needle valve that allows fuel to enter the carb and regulate the fuel level in the float bowl part of the carb. check this by letting the float drop while bowl is removed and gas should trickle down from the needle valve, if it does, then hold the float to the top of its travel but do not force it beyond the stop. fuel should now stop trickling from the needle valve. if it does not stop, then you probably have a little debris clogging the needle valve preventing it from closing completely. this usually causes a flooding condition. By your description, this is not the problem as your mower slound as it is starving for fuel. if no gas flow from needle valve while float is at the bottom of its travel, then you may have a clog in the fuel line, filter or in the tank where the fuel line connects to it. remove fuel line from carb and fuel should flow freely from this hose. if not, check for clog in the fuel line-fuel filter system. hope this helps! oh y, the last steps require a little fresh gas in the tank!

    Water level is set too high and runs over the overflow. how can i adjust the water level in the tank?

    Inside the tank, on a lever arm there should be a cylindrical float that rises and lowers with the water level. Attached to the float is a float rod with a clip that can slide up and down the rod. You can adjust the water level by sliding the clip down to reduce the amount of water entering the tank. As the water fills the tank, the float rises, pushing up the float rod, which in turn pushes up the level that controls the valve allowing water to enter the toilet.

    Toilet flushes fine but when the tank has filled it seems like the float ball keeps bobbing up and down letting more water or air into the tank. it will do this 5/6 times then quits. its almost like it is...

    The ball float follows the tank water level, and repeated cycles of the float dropping and opening the fill valve would likely reflect a leak in the flush valve. You could try adjusting the float arm downward so that it will respond to a lower water level. Try turning off the supply valve, flushing it and listen for water leaking past the flush valve after it closes. If it does, replace the flapper or adjust the chain.

    How to install a toilet trip lever

    Ok eve, Here is the concept of the workings. The "ball" is hollow, cone shaped and open on tje bottom. On its side there is a hole.
    When you lift the Flapper ball, the water drains outand as it does the flapper fills with air so it won't close until the water level drops. The hole in the side bleeds out the air so the flapper will stay down once it is seated in the drain hol. Tank fills and the water pressuer og the filling water increasrs the pressure to hold the flapper seal and covering that vent hole. When you press the lever it has to be held long enough for the water lrvel to drop below the raise flapper so air can get under it or it will immediately drop because the draining water pulls it with the current. So, the adjusting chain mus be short enough to raise the flapper about 45 degreees and held till the water level drops below it. One thing that dictates the amount of time you have to hold it is the water level in the tank. It should be about 5/8 inch from the top of thr frain tube. If water level is correct the flapper will surface enough to grab air in a much shorter time. So the water level is important. Cycle it and you will see what I mean. Good Luck _Ned_
    Let me know if your problem persists Eve. I have one doing the same thing . Make sure the lever is lifting the flapper straight up as possible

    Kohler two peice toilet the water just circles and will not flush.there is plenty of water in holding tank that run through

    These models need to have a flush valve flapper that has a styrofoam float on the lift chaninof the flapper. Go to hardware store or home improvement store and get a 'Korky brand toilet tank flapper with float 'ball". Cut the rubber ring piece away from the flapper and you don't need it (see cut here marks on flapper). Install flapper and adjust the float fairly close to the flapper.
    When the water level drops in the tank and reaches the level of the float on the opne flapper, the flapper quickly closes causing the toilet to have a "surge" of siphon action which forces the water in the bowl to be drawn out.
