How to remove the toilet drain valve screw if it is rusty

First, toilet drain valve installation - drain valve principle.

When the handle on the tank is pulled to flush the toilet, the starter lever in the tank will be lifted. This rebar pulls the wire rope upwards so that the wire rope pulls up the ball or rubber cover at the bottom of the tank. If the opening of the flushometer is smooth, the water in the tank will flow through the ball plug and flush into the lower tank.

The water level of the tank is higher than the level of the elbow.

When the water rushes out, the float floating in the tank will descend, pulling the float arm down, thereby raising the valve plunger of the float valve device and allowing the water to flow into the tank again. The water in the tank pushes the water in the tank, and the water flows into the drain, creating a siphon effect.

Absorbs all the contents of the tank. After the water in the tank flows out, the air is sucked into the bend and the siphon stops. At the same time, the tank plug will fall back to its original position and close the opening of the flushometer.

Second, the installation of toilet drain valve - installation method.

1.Let's start by looking at the type of toilet, split or fitting: the toilet bowl and cistern of the joint are not fastened with screws, and the toilet and cistern of the split are fastened with screws.

2.If it's a joint, it's relatively simple. First open the water tank cover, install the drain valve, find the screw hole at the bottom of the drain valve, and then tighten the screws.

3.If it is separated, there are two screws attached to the joint between the toilet bowl and the cistern. Below the tank, you can see the flange nut hole with a drain valve at the bottom, tighten the nut, and there is a large nut to hold the drain valve.

Both are tightened and firm. Then install the tank, and tighten the two screws on the bottom left of the tank. Finally, put on the tank cover.

It should be noted that when installing a tank in a split toilet, it must be pressed tightly, otherwise there may be a situation where the tank is unstable.

4.When disassembled, it can be reversed.

Now the general toilet drain valve is plastic, your drain valve screws are rusty, try if the angle grinder can be used can not be hard, otherwise the toilet will be rotten.

Hope mine is helpful to you.

Disassembly and assembly method of toilet tank inlet valve:1.The main inlet valve needs to be closed before dismantling begins.

2.Then turn off the inlet valve under the toilet.

3.After that, remove the hose under the toilet.

4.Locate the plastic cap at the bottom of the tank and remove it.

5.After dismantling, you can take out the inlet valve in the tank.

How to install and disassemble the toilet drain valve, life tips are given to you, and you can learn it after reading it.

Step 1: Remove the blue integral inlet valve on the left.

Step 2: Remove the cap of the inlet valve.

Step 4: Separate the two parts, and remove them to turn counterclockwise, with the help of small pliers. It is installed clockwise, and it can be installed by pressing it.

Step 5: The following part can be dismantled again, but it is here that the water is closed, and a few copies can be repaired by placing the small transparent lid on it. If you want to try it back after installing it, use the shower head in the bathroom, remove it and install it at the bottom of the water inlet valve.

Step 6: Turn on the shower switch and let in the water.

Step 7: Lift the float and the water stops to prove that it has been repaired. It turned out that in the toilet, the inner float couldn't stop the water from being lifted. Haha, install the toilet back and you're done.

Hope it can help you solve the problem!

How to disassemble the toilet drain valve screw rust: 1. Disassemble and repair the toilet drain valve 1. Open the toilet tank cover. 2. Find the drain valve inside the silver toilet and observe the composition and structure of the toilet drain valve.

3. Turn off the water inlet switch of the toilet, drain the water in the toilet tank, and use a wrench to unscrew the drain pipe joint. 4. Rotate the screws on the upper part of the drain valve of the toilet to loosen it, and the drain valve can be completely disassembled. 5. First take the sealing ring of the drainage valve of the Fengzu trembling, glue the thin sheet to the bottom of the sealing ring with double-sided ear car glue, and then install the sealing ring back.

1. What should I do if the toilet screw is rusty and can't be screwed down? 1. Do not use a wrench to screw screws with serious rust to prevent screwing slippery edges and corners, breaking screws or screwing wrenches. The handle of the wrench can be struck with a hammer, and the rusted screws often come loose to be unscrewed.

2. The burning screw is seriously corroded, and fire attack can be used. First, use the gas welding flame to fully grill the screws and nuts, and drip engine oil or sewing machine oil on the red-hot screws. The screw expands when heated, squeezes the rust between the screw and the nut, increases the gap, and the screw shrinks rapidly when cold after dripping oil, increasing the gap between the screw and the nut, and the screw can be unscrewed after the oil flows in.

Note that screws with plastic parts nearby should be used with caution, and burned screws should not be used again. 3. If the heating is too serious for the rusty screws, you can also use the rusty screw remover BELINK-1000W to directly heat the screws, which can effectively remove the screws and will not burn the parts next to it. 4. Screw rust remover and lubricating oil.

It is also not very effective for screws with heavy rust.

Disassembly and assembly method of toilet tank inlet valve:1.The main inlet valve needs to be closed before dismantling begins.

2.Then turn off the inlet valve under the toilet.

3.After that, remove the hose under the toilet.

4.Locate the plastic cap at the bottom of the tank and remove it.

5.After dismantling, you can take out the inlet valve in the tank.

2. Next, drain the water in the toilet tank and unscrew the external plugging screw, as shown in the figure below.

3. Then open the cover of the toilet tank, as shown in the figure below.

4. Next, unplug the suction pipe of the toilet tank inlet valve, as shown in the figure below.

5. Finally, take out the inlet valve of the toilet tank, as shown in the figure below.

The toilet seat is broken and needs to be replaced with a new one, but the original screws can't be removed, how can the rusty screws be removed quickly?

1. Heat treatment: Rusty screws can be quickly removed by heating. First, turn on the gas welding gun and bake the rusty screws until the screws appear red, then drip oil upwards so that the oil flows into the threads inside the screws, and can be easily unscrewed after cooling.

2. Carbonic acid treatment: Rusty screws can be removed after carbonic acid treatment. Carbonic acid can react with rust stains, thereby decomposing rust stains and reducing the firmness of the screws.

3. Violent unloading: If there is no gas welding gun and carbonated drinks, you can use violence to unload the rusty screws. First, use a hammer to strike the rusty screw to loosen the inside, and then make the answering wheel with the corresponding screwdriver, fixed at the bayonet of the screw, and tighten it hard to unscrew the screw.

Kiss! Hello, happy to answer your <>

The pro-solution is as follows: 1, you can try a small number of screwdrivers, first gently hit the slot of a deep point, and then try to turn it out 2, you can use pliers to clamp it and try 3, use a small hacksaw to see the screw deeper, like this kind of screw and nut connection, you must screw the nut, turn the black rubber water valve up, you can see the nut, use the saw blade to see 3 minutes, connect the screw to the metal wheel which end is sawed off, the drain valve can be removed 4, take pliers to clamp the exposed part of the screw and rotate, Normally rotate out to the left, rotate to the right 5, use a flat shovel or screwdriver to punch the inner hole out of the shape that can be stuck in the wrench, and then take the wrench to unscrew it 7, use a hand drill to drill the screw out, and then drill from the bottom of the drill, you need to press the board to the end, compact and then turn 8, drill the hexagonal drill tail screw through the deep hole diameter drill bit, after the mold is disassembled, the screw is not forced, and it can be easily disassembled.
