Auditing sanitary hatches for the bathroom and toilet: types, rules of placement, mounting features

For installation of communications in apartments and private houses use two methods: open and closed. With the open method, all pipes and devices are visible, whereas when closed, they are masked by false walls, partitions or ducts.

To provide access to the equipment, sanitary hatches are used for the bathroom and the toilet: the dimensions of the devices usually depend on the dimensions of the hidden pipelines and the number of serviced appliances.

Appointment of inspection hatches in bathrooms

A distinctive feature of modern bathrooms and toilets is a thoughtful design, as a result of which the aesthetic side of the decoration comes to the fore. Technical devices that provide comfortable acceptance of water procedures or ease of use of the toilet are hidden behind thin plastic or plasterboard structures.

Permanent maintenance of pipes is not required, but from time to time there is a need to use valves. For example, to cut off the water supply to the kitchen in connection with the replacement of the mixer, you need to turn off a certain tap.

Metering devices and valves
Devices that resemble doors or hatches are necessary to maintain metering devices that are masked behind partitions. You can quickly take readings from the counters of hot and cold water by moving the flap back or opening the door.

If the bathroom is completely covered with plastic or tiles, more hatches will be needed. Suppose one of the nodes, to which constant access is necessary, is the place of installation of the water seal for the bath. If the protective screen is made deaf, it will have to be dismantled each time a blockage in the pipe occurs or a leak occurs at the junction of the siphon parts.

It can be concluded that any components and devices that require regular testing should be freely available. And with the full lining of the rooms with tiles or plastic, this can only be achieved with the help of technical hatches.

What is necessary to provide access

For easier repair work, the pipeline that supplies water to an apartment or house is divided into convenient service areas. Each separate section, if necessary, is cut off by a valve or a ball valve mounted on the pipe. If there is such a possibility, most of the valves are mounted in one place.

Manifold wiring in the hatch
Collector wiring is a convenient way to divide the system into separate circuits. The advantage is the autonomous use of separate lines in case of failure of neighboring lines, the disadvantage is a more expensive installation.

When all significant locking, regulating and water-folding devices are masked behind a false wall, but are concentrated in one place, it is much easier to build a hatch for access to them. The door will be different in size, but it will not damage the appearance of the partition or the functionality of the hatch.

Modern apartments are equipped with so-called blocks or input nodes. In addition to the ball valves, the standard assembly includes a water purification filter, a pair of metering devices, and a pressure reducer. The filter is often installed on the bypass in order to be able to flush with reverse flow of water. All devices are equipped with ball valves for quick removal due to repair or replacement.

Input node with filters
The entrance node with filters and other devices is hidden behind the partition, which protects the equipment and helps to maintain the interior of the bathroom in the same style

In the combined bathroom or toilet there is a sewer riser. In parallel, the pipes for centralized cold-water and hot-water systems are located in it. If the corner with vertically placed highways is closed with a box, then a hatch is also installed on it - opposite the stopcocks. As you can see, there are several options for the placement of the audit hatch in the bathroom, as well as in the toilet.

Types of sanitary hatches

There are a lot of reasons for equipping the bathrooms with inspection hatches, but even more types of these hatches. There are models of factory-made, overall and solid, made of stainless steel or plastic. They are contrasted with homemade panels made of improvised building material and fasteners purchased in the store. When dividing into groups, different sides of models are used.

Classification # 1: by way of opening

The plumbing hatch is a door that can swing open, move aside, lean back or move in response to pressure.

Hinged doors are a traditional type, typical of most entrance doors, furniture doors and window frames. They are hinged on one side, easy to open and serve for a long time thanks to a simple device. To open the hatch, you must pull the handle, which can be normal or equipped with a latch or lock.

Sliding models resemble ordinary swing, but have a more complex design of loops. The fastener consists of three links that allow you to move the hatch to the side in two steps: first push it towards you (1.5-2 cm) and then carefully pull it to the side.

Sliding stealth hatch
Such models became popular when it became necessary to install manholes in hard-to-reach places: behind bathtubs, toilet bowls, bidets or pieces of furniture.

Folding hatches are arranged according to a simple principle: on one side there is a fixing fastener, on the other - a supporting mechanism. When the latch is opened, the door simply leans forward, moves from the vertical position to the horizontal.

Push models are classified as "invisible". They are difficult to notice, as the material facing the hatch often coincides with the overall decoration of the walls.To gain access to the sanitary cabinet, you need to slightly press the panel, after which it will move forward. Then there are various ways to further open - either plowing or moving in one direction.

Choosing the hatch by the method of opening, it is necessary to analyze the installation location and decide which model to install is advisable, and which will cause difficulties in the process of servicing devices or components.

Classification # 2: by material

Factory models can be divided into two large groups. The first includes metal products made of stainless steel and equipped with high-quality fasteners. They are a solid frame with a door that can be opened in any of the above ways. Most of the proposals are designed "under the tile", but the doors can be decorated with any materials.

The second group includes plastic hatches.They are less reliable, differ in the small weight and ease of installation. The cost of plastic products is much lower. If a reliable steel hatch costs 3.5-4.5 thousand rubles, the plastic equivalent has an average price of 200-350 rubles.

Economical plastic hatch
Buying an inexpensive plastic hatch is an outlet for home craftsmen who repair their own bathrooms. It can be fixed with screws, liquid nails and even sealant

Unlike factory options, improvised hatches are not made of metal, although in the manufacture of the frame they often use a metal profile. For the panel of the hatch choose an inexpensive, but durable material: drywall, plastic, wood. It is convenient to glue tiles to drywall blanks if the task of the master is to create an invisible manhole.

Choosing a particular material, it is necessary to properly assess its durability and water resistance. If you take the usual, rather than moisture-resistant drywall, then it will quickly lose its qualities, begin to swell and crumble. A similar process occurs with untreated wood, which over time deforms from excess moisture and temperature changes.

Classification # 3: by degree of disguise

This option of dividing into groups can be called a conditional classification, since there is no clear distinction between the two categories of hatches: some of them are noticeable, the second are called “invisible”.

The first group includes structures that stand out from the surrounding lining. For example, it is white plastic hatches, which are noticeable due to its color and material. If you put such a hatch behind the toilet, it immediately catches the eye, however, absolutely does not spoil the overall picture, as it is combined with sanitary equipment in color.

Invisibles are visually hidden constructions. There is a disguise due to the use of the same ceramic tile in facing of the walls and the manhole cover. Thanks to the dimensions of the frame fitted to the tile elements and the tile joints, the hatch plane merges with the wall decoration. As a result, it is difficult for an uninitiated person to determine where a technical opening is located.

Invisible man with suction cup
The difficulty of finding a plumbing hatch increases if the door does not have a handle. Such models usually have a pressure opening method or are removed using suction cups.

The advantage of the "invisible" is the complete merger of the manhole cover with the wall, so that the wall decoration looks solid, untouched.

Classification # 4: By Installation

It would seem that all sanitary hatches for the toilet or bathroom are installed in the wall. This is a common location, but there are also ceiling and floor views.

Ceiling openings are necessary to maintain the communications that are above the suspended structures. Such modifications are more accurately called audit, rather than plumbing, as they open up access to ventilation ducts and electrical wires.

Using the ceiling access hatch
Installation of the sunroof is carried out during installation of the suspended structure. Its device does not differ from wall analogs - the same hinged door that latches onto the latch

Holes located in the floor lead to the sewer pipes or water supply, which is located below the level of the final coating. Such an arrangement of communications is not typical for typical wiring, but can occur when the floor is raised or create thick insulation (for example, in private houses or on the first floors of apartment buildings).

Hatches installed in the floor or in floor boxes lead to the joints of pipes, turns, ladders - that is, to structures that need maintenance and can not be sealed.There have been cases when, in order to access a pipeline rupture at the junction of individual elements, it was necessary not only to remove the topcoat, but also to hammer in the screed.

In addition, the technical can be considered hatches, mounted in the floor protective boxes and the screen, which is located under the bathroom.

Hatch installation instructions

The nuances of installation, as well as the choice of tools, completely depend on the type of hatch and the material of the partition. Consider two options for installing the hatch - the factory model and a homemade auditing design under the bath.

Installation of the metal model "under the tile"

To install a hidden hatch, lined with tiles, you need a hammer drill, a screwdriver, liquid nails with a gun, a spatula, a set of screwdrivers, a marker and a tape measure for marking, a sponge for cleaning.

The factory model with a metal frame will be mounted in a false-wall made of plasterboard prepared for facing with ceramic tiles. In order for the panels to withstand the additional load, it is necessary to make the embeds from the metal profile along the perimeter of the hatch.

The final touch is a plastic corner framing of the hatch. Plastic is thin, however, even at the first stage, in the process of marking and cutting the window, it is necessary to take into account its thickness. After completion of the work, there should be a gap of no more than 2 mm between the plastic edge of the door and the frame.

Ready hatch with handle
Because of the handle and the plastic frame, it is difficult to call the hatch in the full sense of the word "invisible", but it is in perfect harmony with the lining of the bathroom

If the partition is made of plastic, then plastic is also used to finish the door instead of the tile. The hatch will weigh less, but mortgages are necessary in any case, otherwise the metal structure will not be fixed.

Bath hatch making tips

A small hatch under the bathroom, at the installation site of the strapping, will come in handy when you need to replace a plastic siphon or eliminate leaks due to the depressurization of the connections. The same hatch can be installed on the other hand, but to create a niche for disinfectants and detergents.

To work you will need a metal profile, a piece of drywall and tile, which made the finishing of the bathroom and the screen under the bathroom.

If you have to use the hatch infrequently, the seams between it can be filled with a screen with silicone sealant. It will fill the gap, and the door will look more organic and less noticeable. If necessary, the frozen sealant can be cut through with a construction or stationery knife.

How to choose the right size

The most difficult to correct errors associated with the wrong choice of dimensions of the sanitary hatch. When installing structures that serve several devices, it should be remembered that, apart from taking monthly readings from metering devices, occasionally it will be necessary to replace or repair “on site” for which a small window will not be enough.

The larger the inspection hatch, the wider the coverage area and the possibility of repair work. It is good if all significant pipe joints, stop valves and devices that require regular maintenance get into the open technical area.

Maintenance hatch
If a gas heater is installed in a hidden niche or behind a false-wall, then access to the regulating parts of the unit and strapping should be made as large as possible.

Factory models have typical dimensions, for example, 55x45 cm or 70x50 cm. When producing hatches "under the tile", manufacturers are guided by the popular standards of facing elements. There are no certain standards for self-made structures, you need to build on the dimensions of the technical opening and the possibilities of creating a functional hatch from the materials at hand.

Conclusions and useful video on the topic

Features of the installation of homemade and factory models quite a lot. To find out about some of them, we suggest watching interesting videos.
