Armature for the flush tank with the lower liner: installation features, types and reviews
Plumbing repair is a delicate matter, which is why most people prefer to contact specialists. But it is not always possible to call a professional, and in most cases a breakdown is completely disposable on its own. For example, a toilet bowl that always “rustles” without respite and the water constantly pouring inside the faience throne will surely lead anyone to conclude that it is necessary to repair the fittings of the drain tank with the lower connection or other manipulations inside the storage tank. Such an operation is quite capable of performing personally.
Other signs of worn reinforcement
The water itself constantly flowing in the tank can signal several types of breakage:
Wear of the locking membrane. This often happens with long-term shutdowns of water, sludge during operation of the rubber dries and cracks. Will require new fittings for the drain tank with the lower liner.
Wrong float level relative to overflow. You only need to adjust the position of the float inside the tank, performed in minutes.
Leaks inside the bulk valve or failure of the locking mechanism. Such failures are eliminated by replacing the entire node.
Also, the wear of gaskets can lead to a leak at the junction of the supply hose and tank. Replacing a damaged gasket, replacing a worn hose entirely, or a new stop valve of a lower tank with a lower eyeliner can solve this problem. There may also be leaks at the tank mounting points, which may indicate improper installation or damage during operation. In any case, to begin with, it is worthwhile to finally decide how serious the damage is, determine the faulty unit and calculate your own strength, since after careless intervention in the plumbing system, the cost of a specialist can increase significantly.
Determining the type of reinforcement
To identify the causes often have to look inside the cistern, it is done quite simply. Most of the existing systems, except those that are completely outdated with ropes, have working buttons or a rod, which is fastened using internal threads.By unscrewing this element from the main part of the valve, you can remove the tank cover and look inside. Armature for the flush cistern with the lower liner is different in that the water-bearing hose is connected more covertly to the cistern of the toilet bowl, namely behind and below.
Choosing the right replacement
If you come to the conclusion that you need a complete repair of such a node as the fittings for the drain tank with the lower supply pipe, then you need to decide on the replacement. Unfortunately, the outdated types of flush fittings will have to be changed along with the cistern, and even with the entire toilet bowl, so their repair comes down to temporary measures or the use of handicrafts. But the majority of modern models of flush tanks are compatible with universal valves. When choosing a suitable model of fittings, it is important to determine the liner, bottom or side, while the method of switching on, the button or the exhaust lever can be chosen to your own taste. Push-button fittings can be made with two buttons with the implementation of the regime of incomplete drainage, when choosing such a model, you should take into account the tank capacity. You should also be aware that different manufacturers have their own design and assembly of the valve of the cistern with the lower liner, therefore, it can be extremely difficult to select a broken individual part.
Preparation for work
If your armature for the flush tank with the lower liner requires replacement, and you decide to do the repair yourself, you will need to prepare a workplace and some set of simple tools. The first step is to block the access of water to the tank and flush the water. Working with plumbing means possible splashes of water and drops on the floor, so you should stock up with a rag or sponge. Threaded connections on tanks are usually tightened only by hand, since plastic is the main material of the reinforcement. You may need pliers or an adjustable wrench for tight nuts. To flush the tank and remove plaque, you may need detergents used for baths or tiles.
Dismantling the drain tank fittings with the lower liner
As standard, the valve consists of two independent components: a water inlet valve with a locking system and a manual-flush valve. Often, replacement requires only one of the nodes that can be considered when purchasing. To remove the inlet valve, you must first unscrew the flexible hose of the supply line, and then fixing the plastic nut, after which the entire valve design can be removed through the top of the tank.
The flushing mechanism in universal fittings is fastened with an external nut, for access to which it is necessary to remove the tank entirely. First, remove the special bolts that hold the water tank, then turn the tank for convenience and unscrew the exhaust valve nut. With a sufficient length of the supply hose, the procedure for replacing the valve's outlet valve can be carried out without dismantling the intake mechanism.
Installation of the tank bottom drain fittings
Installation is in the reverse order. Manufacturers clearly indicate in the instructions of the place of use of special pads. All connections must be twisted without using keys or other tools. First, install a drain valve in the tank and fix it with a nut. Two screws fastening the tank to the toilet should be tightened simultaneously and evenly to avoid distortions of the joint. The connection of the intake valve is also necessary to make hands, these precautions protect the fragile porcelain of the tank from chipping and soft gaskets against chafing.
If you came across the sale of identical fittings for the cistern with the lower liner, which was before, the adjustment can be made by the labels of the old mechanism.In another case, you will have to customize the product in place right in the tank, the benefit is not particularly difficult. Universal valves are equipped with special movable joints on the latches, allowing you to adjust the device to a large number of models of tanks. First, adjust the inlet valve so that the level of water intake is sufficient, but does not exceed the outlet of the outlet valve. It is better to check at once, having collected water in a tank in the usual way through the giving hose. Next, the drain valve is adjusted to the height of the tank; the button without screwing in should be a few mm higher than the level of the lid. Later, during installation, the button will go down and become one level with the surface of the tank.
Among the variety represented on the market, professionals opt for models of fittings cost from 700 rubles. The quality of materials of cheaper options is often quite low, besides, manufacturers, in pursuit of cost reduction, neglect the installation of filters. All this can lead to a significant reduction in the service life of the water supply mechanism in the toilet bowl.At the same time, many users note that even the most inexpensive models are able to cope with the task of dialing and draining water without any special problems. The fact is that the manufacturing techniques of valves are quite simple, and the material of the body and gaskets presents ample opportunities for modifications. Expensive models differ only in characteristics that affect the durability of the device.
