In the process of equipping the bathroom, it is important to think about safety. In one room there are several outlets for water supply at once, so they should be supplemented with forced drain systems. Only in this case, it will be possible to avoid a situation where a crane accidentally forgotten in the open position will lead to huge damage. It is especially important to provide a freestanding tub overflow drain. The set of water in the tank occurs very quickly, and in the process of water procedures, many deliberately leave the tap open unattended, waiting until the required volume is collected.
Modern designs do not necessarily provide an appropriate mechanism that will prevent flooding. Alternatively, you can use the common drain system provided on the bath floor. At the same time, its organization is a complex process and is carried out exclusively at the stage of overhaul. Having a freestanding tub drain without overflow would be a smart decision, given the possible costs of restoring your and a neighbor’s apartment in case of flooding. It will also allow you to comply with building codes and safely operate plumbing.
What is an overflow drain?
This element is found everywhere in the apartment:
- in the kitchen in the sink;
- in the washbasin;
- in the bath.
The system is quite simple, and this has earned success among designers and buyers. It duplicates the main drain, providing water drainage when a certain level is reached. For example, if the main hole is clogged or plugged, then the backup system will not allow water to overflow.
Usually, the corresponding opening of the system is located slightly below the faucet. The drain may have a special curtain or window that allows you to make the plumbing design more attractive. In terms of materials that are used in the production process, there are practically no restrictions. Equipment can be made of metal, plastic, or rubber. Usually, the sink is selected according to the design and material used to make the faucet.
What is the overflow drain responsible for?
The drainage system avoids flooding in the bathroom. If a person is distracted while filling the container, then he may remember too late to fill the liquid. Drainage will allow you to divert excess water, avoiding overflow. The system simply diverts excess fluid directly to the indoor drain system. If the pipe leading to the bath is clogged, then this will not be a problem for the drainage system. It connects slightly below the main segment, which allows it to operate more efficiently.
How does an overflow drain work?
A tub without overflow is not safe, as flooding can occur for a variety of reasons. For example, the deterioration of the design of the crane can lead to depressurization at a time when all family members are out of the house. If the liquid discharge system is not duplicated, then this will inevitably lead to flooding. The overflow drain is located in such a way as to ensure comfortable use of the bath. It is located almost in front of the side, so the depth of the bath remains almost unchanged. If necessary, the hole can always be closed with a lid, if at the moment the user has full control of the water intake.
The overflow drain bathtub is available in two versions:
- Classical system. In it, the overflow drain is located on the side, which allows you to collect excess liquid and send it directly to the waste line.
- Built-in overflow. This format is more aesthetic since the intake element is located directly under the tap. With its help, water is drained into the sewer.
Many buyers are interested in the question of how reliable such a system is. Indeed, draining may not work under certain circumstances. For example, if the hole was blocked by debris or when installing a special plug. You also need to pay attention to the condition of pipes and connecting elements. Gaskets tend to dry out, which leads to loss of tightness of the system. It is better to replace the old system to avoid digging.
How to fix a leaky overflow drain?
Most of the problems that may arise during the operation of the drainage system can be eliminated independently. To do this, it is enough to determine the location of the leak. Gaskets are the most likely cause. You can replace them with similar elements from the repair kit. The repair process is as easy as replacing the washer. It is necessary to purchase a set of gaskets, and then unscrew the tube from the water receiver. The next step is to lubricate the place for installing the gasket with silicone grease, install the replacement element and firmly screw the tube in place.
What to do if you do not need a drain for overflow?
Despite the simplicity of design, the drainage system has some disadvantages. Since the system is connected directly to the sewer, in some cases it can become a source of unpleasant odor in the room. You can fix this problem with a cover. At the same time, the hole in the bath design may not look aesthetically pleasing. This is especially noticeable in free-standing structures. In such a situation, the best solution would be to purchase a special bathtub model, which provides overflow protection.
An obligatory moment is to clarify the current building regulations. In some regions, the presence of drainage is a mandatory requirement, which simply does not allow plumbing to be installed without this element. An easier and faster way to fix the problem may be to install a special cover. It allows you to close the hole that is used for drainage. It should be used only if the buyer is sure that the risk of overflow is excluded during the collection of water.
Manufacturers offer a huge number of covers, which allows you to choose a transparent version or a product that matches the color of the bath. Using the overflow prevention system, a person is always sure that there are no risks of flooding the premises. A simple solution turns out to be the most effective way to eliminate additional costs.
