Dripping or leaking tap in the bath water not only causes irritation. It causes extra cost for water can leave the track rusty plaque plumbing coating. Finally, the leaking faucet can cause a flood, flood you and the neighbors. Often the cause of leakage becomes a wear pads. Change the faulty gasket in the faucet in the bathroom, you can own.
Laying in the crane, its purpose and the device
Gasket - is an important part of the crane structure, it seals the valve seat and the housing, blocking the flow of water. When closing the working lining is strongly pressed onto the seat and at the same time experiencing significant static load. Furthermore, it acting dynamic forces from the flow of the flowing water.
Besides working pads, one or more O-rings are provided in the design, arranged between the crane body and the fastening core, sealing threaded connections of parts mechanism. These rings are less subject to wear, but if replacement labor pads did not give the desired effect, they also need to be replaced.
Causes of Failure
Before starting to disassemble the faucet, you need to make sure that the reason is podtekaniya- gasket. If you drop or trickle of water when fully closed the valve appear from the spout, it is a sure sign of failure of the working lining. In this case, you can begin disassembly to replace the crane working pads. Visual inspection of the problem is easy to install:
- Form changed visible dents.
- Visible gaps.
- Partially or completely destroyed.
The reasons for failure of the seal may be several:
- Improperly selected toes-out in a previous installation.
- Distortions during mounting.
- Low quality rubber.
- Heavy pollution of water impurities.
- The accumulation of mineral deposits.
Regardless of the cause, the treatment of one thing: the replacement of the seal. In the case of grains of sand or sediment damage should think about how to put the filters of mechanical and chemical treatment of water.
Instruments
Tools and auxiliary equipment is better to prepare in advance. To replace the need to:
- Set of spanners. You can use two universal movable or gas key. Excellent fit Adjustable pliers.
- Screwdriver Set.
- Pliers or tongs.
- A scalpel or sharp knife durable.
- A piece of cloth to protect the chrome parts with loosening.
- Set of gaskets (repair kit for ceramic kran- boxes).
- Box for small parts.
- Vinegar to remove limescale.
Better stock up on set with seals of different sizes, to the middle of the work does not throw a mixer exploded and not run to the store for a suitable.
How to replace the gasket
The sequence of actions is slightly different depending on the type of head parts. Getting started is carried out the same.
Training
All work in the bathroom begins with the water supply overlap. If pipes have separate valves that shut off the need as close as possible to the repaired mixer. If there are no such valves have to cover the entire riser.
Next you need to drain the remaining water from the pipes. Drain hole must be closed stopper or lay a cloth, plastic, cardboard, etc. It will not lose small parts that can fall during dismantling. Cardboard will also protect the surface of the bath accidentally falling tools.
worm crane
Proceed as follows:
- Remove the plastic cover from the handle. Under it is the fixing screw.
- Unscrew the screw securing the handle, remove it by pulling.
- It seems upper head parts. Grab it suitable size wrench and gently moved. If the thread become attached due to calcification, drench them with vinegar and leave for some time. You can also use WD40 liquid.
- Unscrew the axlebox housing crane. Inspect the valve seat. If it is not visible povrezhdeniy- cause of leakage in the working lining.
- Grab a pair of pliers or a body perestavnymi mites. Suitable screwdriver unscrew the fastening screw compactor. Save the screw and washer.
- Pry off the pad with a screwdriver or a knife, then remove it.
Now is the time to carefully examine the body and head parts, assess the condition of gaskets. The housing must not have damage. In this case, it will have to be replaced. If it is visible limescale deposits - it needs to be removed.
Further procedure is as follows:
- Clear place sealant installation against dirt and mineral deposits.
- Choose the appropriate size gasket. New can be a somewhat greater thickness than the original part. But the outer and inner diameters must match exactly. If the gasket is velika- completely turn off the tap will not be possible. If mala- the gap will also leak water. The lining should rise at mount with some effort.
- Tighten the screw fixing the seal to the stem.
Important! Do not forget to put a puck.
- Wrap thread axlebox ribbon FUM, linen thread or other sealant.
- Insert it into the hole, screw in until it stops. You should not put too much usiliy- so you can strip the threads and have already changed the entire mixer.
- Fit the handle and tighten the fixing screw.
You can now open the water supply and check the result of the replacement work.
Mixer with a flywheel
In some models of mixers with the flywheel housing is a solid piece. Before starting the disassembly is required to remove the cap by prying with a screwdriver or a knife. Care should be taken not to scratch chromed.
Under the cap will screw securing the flywheel. It will also need to unscrew and remove a flywheel. Next, unscrew the trim. It will now be visible narrow nut holding the head parts. Unscrew it must be cautious to disrupt key or mites are not damaged chrome plating. It is better to wrap the body with a cloth. Subsequent operations are the same as described above.
Repair of ceramic head parts
Ceramic head parts worth considerably more expensive than brass. But it pays to its high reliability and long life. Most mixers correspond to standard sizes kran- axle boxes, and if possible, a better substitute for brass, ceramic, choosing the appropriate size.
Although reliable, low quality water (sand, high salinity) ceramic cores may also be damaged. To repair them you need to buy a repair kit.
Proceed as follows:
- Remove the cover on the handle by slipping a screwdriver or a knife.
- Unscrew the handle mounting screw and remove it by pulling.
- An adjustable wrench to unscrew the core.
Attention! rotation- direction counterclockwise.
- Remove the locking clip and lift it with a flat screwdriver.
- Disassemble the head parts podstelennom on a piece of cloth. The stem can be pushed out of the housing by tapping it with your finger.
- Replace the ceramic plate and rubber rings from the new repair kit.
- Apply a small amount of silicone grease on the threaded rod.
- Assemble in reverse order to latch locking clip.
- Wound on the external threads of the tap-letter tape FUM, plumbing or other thread sealant.
- Gently twist core in the faucet body. You should not use excessive force to avoid damaging the threads. In this case it is necessary to replace the entire faucet.
- Put on the handle on the stem, tighten the screw of its fastening. Insert the plug.
Now it is possible to supply water to the pipeline. If the thread through the head parts mounting stand a drop of water, you should tighten it a quarter turn.
Recommendations made and possible difficulties.
Skilled craftsmen have gathered the most common mistakes when replacing gaskets:
- Too big efforts made during fastener torque kran- Books. The seal is pressed at the same time, and after a while the problem persists. Therefore, the thread must be tightened carefully. If the thread under test through trickle of water droplets can be tighten by a quarter or half turn.
- Correct installation of seals in mounting. The displacement of the ring relative to the longitudinal axis is skewed, the seal disruption and rapid wear.
- Error in determining the cause of the leak. This may be a rubber gasket will not wear, and, for example, wear of the worm drive or the valve seat. If the replacement does not help, you should check all the details of the mechanism itself and the mixer housing for mechanical damage.
- Damage chrome coating mixer parts. This happens if you lose grip of sharp or heavy tools. To avoid this, you can wrap the items with a soft cloth or wrap an elastic bandage.
To reduce the wear of the seals and extend their work, it is worth thinking about installing filters. Mechanical are inexpensive and retain sand particles and rust, which are particularly afraid of ceramic kran- axlebox. Filters and iron removal demineralization are more expensive, but protect the plumbing in the bathroom and in the kitchen, washing machines and dishwashers from harmful deposits.
It is wise to plan for timely replacement of pipes in the sovremennye- plastic and whether the metal and non-corrosive. With these tubes all the plumbing last longer.
