Preparation for maintenance: tools and accessories
Required tools: active wrench, cross screwdriver, one-word screwdriver, rags (drinking water in tanks), buckets (water in tanks)。
Common fittings: based on the results of the screening, such as total intake valves, drain valve seals (or complete drainage valves), water tanks connected to seals, rustproof bolts (if connected to bolts rust), it is recommended that photographs be taken in advance or used accessories be purchased at the hardware store to ensure that the model matches (the size of toilet parts may vary from brand to brand)。
Discretion maintenance: step-by-step operation
(i) leakage maintenance of entering valves
Water off and power out: first, the toilet enters the total water valve (usually on the left side of the toilet, with the end of the clockwise) and if the toilet has a smart function, the power is switched off and electrical contact is avoided。
Empty water tanks: press the flushing button to empty the water in the tanks and, if there is any remaining water, dry it with a rag or sponge to prevent leakage during maintenance。
Dismantling of old water entering valves: wrenching of the nuts attached to the bottom of the water tank to enter the water valves with a wrench (care to rag the mat and avoid scratching the water tank), then extracting the old water entering valves from the tank and removing the pipes attached to the water valves。
Installation of new water entry valves: place new water entry valves in the water tank, point them to the installation hole at the bottom, tighten the nut from outside the water tank (with a moderate strength to avoid cracking the water tank) and connect to the pipe to ensure that the interface is not loose。
To debug the water level: open the total water valve, observe the rise in the water level of the tank, if the water level is too high (over the spill pipe), adjust the float height on the water valve (old floats can bend metal poles, new float valves can rotate poles) until the water level is 1-2 cm above the top of the spill pipe。
(ii) leaking maintenance of drainage valves
Shut-down and drainage: step 1-2, along with maintenance of the valve, to ensure that the tank is free of water。
Examination of drainage valves: open the caps of the water tank and observe the location of the drain valves, without the need to remove the full drain valves if they are merely ageing, and remove the old seals directly (usually black rubber rings, easily pried down by hand or screwdrivers); if the valves are deformed or the whole drain valves are damaged, the entire drain valves (screw the fixed nut at the bottom of the tank, removed from the tank)。
Replacement fittings: new seals will be placed on the drain valve (to ensure that there is no gap) or new drainage valves will be installed (to point to the holes in the bottom of the tank and to tighten the bottom nut)。
Test sealability: open the total water valve, when the tank is filled with water, and observe whether there is a leak in the drain valve, if the flushing button is pressed, the water is discharged normally and the seal is closed when released, indicating the success of the maintenance。
(iii) water leak maintenance in the toilet connection
Shut down and drain: close the water valve and drain the water from the tank。
Dismantling water tanks: strew the fixed bolts at the top of the tanks with a screwdriver (usually 2-3 at the sides or in the middle of the tanks), then gently lift the tanks and place them on the flat ground (with care to avoid collisions and prevent break-ups)。
Replacement of seals / tight bolts: if the seals are ageing, remove the old cushions and replace them with new seals (to ensure that the size is the same and that the interface between the bottom of the water tank and the main toilet is attached); if the bolts are loose, the bolts of the bottom are tightened with a wrench (both strength and to avoid breaking the bolts)。
Reloading tank: put the tank back on the main toilet, point to the bolt hole, tighten the fixed bolt at the top, then open the total water valve, and see if the interface leaks。
Iv. Post-maintenance inspection and attention
Test leakage: when the maintenance is completed, the water valve is opened, the water tank is filled, and the water tank is static for one to two hours, to observe whether the water level in the tank has fallen, whether there is water accumulation on the ground and, if all is normal, to indicate the success of the maintenance。
Avoid excessive force: when disassembly and bolts are installed, the strength is moderate, the toilet water tank is mostly ceramic material, and excessive force can lead to cracking。
Spare parts: in the absence of new accessories for the time being, the old parts that have been removed must be properly preserved, avoid loss and facilitate subsequent purchases。
In exceptional cases, if water leaks after maintenance or if a water tank is found to have cracks and spare parts are not matched, it is recommended to contact the toilet brand after sale or professional maintenance staff to avoid more serious damage from self-repair。
As a result of the above steps, the problem of leaks in most toilet tanks has been successfully addressed, not only to save maintenance costs but also to avoid waste of water in a timely manner. Where there is uncertainty in the maintenance process, it is possible to consult professionals in hardware stores with toilet instructions or advice。
