Global work on the replacement of water and sewer pipes is inevitable when overhauling the bathroom. How to arrange and connect the pipes, so that for many years to stop being afraid of leaks and enjoy comfort?
The entire system of pipes, both plumbing and sewer, as well as plumbing, faucets, water meters and coarse filters, stop valves and fittings, are called wiring .
Layout types
There are only 3 pipe routing systems:
Serial , the most common in standard apartments where there are few pipes and connection points. All consumers are connected to one pipe by means of tees. The wiring in the bathroom, assembled according to this scheme, is more compact, there are fewer connections( and, therefore, possible places of leakage).Another plus is the low overall cost and spaciousness of the assembly. However, with a sequential scheme, a pressure drop occurs when several cranes or devices are switched on.
The collector is used in apartments and houses where a large number of water intake points are connected: several sinks and toilets, a bath or a jacuzzi, a washing machine, a dishwasher, a boiler or a boiler. Under this scheme, there are collectors for the cold and hot water in the wiring structure, connected to the water supply, they do not allow the water pressure drop in the system. From them, the water through separate pipes goes directly to the sanitary or household appliance, its supply can be blocked for any consumer without damage to the others.
Mixed , when part of the devices are connected through a manifold( for example, washing machine and dishwasher, bath), and part - in series.
By the method of laying the wiring is:
- open, when all the pipes are located along the walls, in sight. With this method, it is easy to maintain and replace them, and the installation itself does not require repair.
- hidden, in which the pipes are hidden in the walls( as described here).This method is more laborious and requires a quality connection of parts, but the bathroom looks more modern and more beautiful. Pipes are laid in pre-traversed canals, and before this, preferably, in the corrugation.
- combined, when the pipes are closed with a box or false panels.
Selection of material and fineness of the work of
For modern repairs, polypropylene pipes and sewer pipes are absolutely preferred. To connect them a special tool will be required, but they will be reliable and durable. Also polypropylene is resistant to corrosion, and deposits and rust do not accumulate inside such pipes. In the absence of a tool, it is possible to make wiring with metal-plastic pipes, which are assembled with fittings-that's the instructions. For serial wiring, in addition to fittings, tees are needed to connect plumbing and household appliances. The diameter of the sewer pipes for the shells and the bathroom is 50 mm, for the toilet - 100 mm.
Advice for high-quality pipe routing:
- Before assembling, it is necessary to check the integrity of pipes, connecting elements, valves, and also their number.
- When laying sewer pipes horizontally, for example from a bathroom or a washing machine, it is necessary to provide a slope of 2-4 cm for each meter of length towards the riser.
- Pipes with an external wiring diagram must be fixed to the wall with clamps, placing them apart from each other at a distance of about 10 pipe diameters. Use better clamps made of plastic or metal with rubber seals, so that the pipe is fixed not too hard.
- Sewer pipes can not bend by 90 degrees or lie strictly parallel to the floor, this leads to clogging.
Wiring for your bathroom
The easiest way is to make a serial wiring. This is the optimal time and cost-effective option, if you live in an apartment: you need only 2 pipes, and not 4 or more, as with a collector connection. In addition, to hide such a wiring in a small bathroom of a standard apartment is easier.
Before buying pipes and accessories, it is necessary to make a bathroom plan with the dimensions and distances between the devices and the wiring plan in order to accurately calculate the pipe length and the number of connections, tees, valves, etc. Beginning intra-apartment wiring from the risers with two valves to pipes with hot and cold water, then installed filters for rough cleaning, meters for water. On the pipe with cold water, there follows a tee, from which there is a diversion to the toilet.
If you decide to install additional filters( for example, water softening), then this is done at this stage. Then, in turn, take turns to the sink and the bathroom, depending on their location in the room. The bathroom mixer is attached to a tap, which is welded or screwed directly to the pipes, the mixer on the sink is usually connected via flexible hoses. Then follows the outlets to the washing machine, to the kitchen sink.
When concealed or combined wiring in the places of valves, meters, large units, inspection hatchways should be provided for revision.
To perform a difficult routing for a beginner may not be able to. Poor-quality assembly can lead to leaks and damage, both in your apartment and in the next, so it's better to entrust the work to professionals.
