Installation of coarse water filter

Water flowing through pipes to the consumer always contains a certain amount of sand, insoluble impurities and suspensions. They add scale and limescale from the pipes. Sometimes there is a rewinding material. If all this goes straight through the counter, the faucet or into the toilet bowl, the device for heating the water, then they all quickly break down, and the grids of the faucets will be clogged and the water will not flow out. To avoid this, the installation of a coarse water filter is provided at the water inlet to a house or apartment.

Varieties and working principle

In practice, such coarse filters are used:

• Mesh filters. They are straight and skew, as well as non-flushing and self-washing. The non-washable coarse screen filters include all structures with settling tanks (mud tanks), which can be angled to the filter housing (oblique) and under it (straight lines). To clean the accumulated dirt, these filters must be removed and rinsed. To make it easy to remove all contaminants, there is a special cover at the bottom of the settler. In this case, the water in the house or apartment will be blocked. Self-cleaning filters have a special drainage drain to the sewer. On it automatically accumulated dirt is removed from the filter.. The mesh size of the mesh is from 50 to 500 microns. It is made of stainless steel and has a rather long service life. The filter housing is made of brass or metal.
• Cartridge filters. This flask is transparent to cold water or metallic to hot water. Inside a removable cartridge is installed from a wound synthetic yarn, polyester or extruded fiber. Cell size ranges from 1 to 30 microns. For mechanical cleaning, a cartridge with a cell of 5 microns and above is sufficient.

Whatever the filters, the principle of action they have one: water, falling into the filter and passing through the mesh or cartridge, is cleared of insoluble impurities.

Installation process

Since the coarse filter must protect all plumbing from solid impurities in the water supply, it is very important to know how to install it correctly. Do it on the input of water into the room after the valves. On the body of each filter model there is an arrow indicating the direction of the filter installation. It should stand in the direction of water movement. This is important because the improperly installed filter will not work.

Mesh oblique filter is installed on a horizontal (if the water goes from the top down) or a vertical pipeline under constrained conditions. The sloping arrangement of the sump does not require a large amount of space.

Since all the connections are threaded, for installation it is enough to wind the thread with a FUM tape or flax and screw the filter to the valve, and then screw the water meter onto it.

Before performing work should shut off the water.

Strainer straight filter mounted on a straight pipe in the presence around the free space. This is due to the size of the sump. It is somewhat larger than a skew filter and requires space under it in order to unscrew the lid of the sump and clean the filter. Its installation is performed in the same way as in the first case.

After completion of work and the start-up of water should check the joints for leaks. All leaking joints must be tightened.

How to install the cartridge filter? It is installed only horizontally and after the strainer:

1. Cut a piece of pipe. Its dimensions depend on the distance between the inlet and outlet openings of the filter, other parts (cap nuts, adapters, etc.). Their set is individual in each case.
2. The metal pipes are threaded, and the corresponding fitting is soldered to the polypropylene pipe.
3. The fittings are screwed to both ends of the pipe using sealing materials (FUM tapes or flax).
4. Assemble the design of the filter.
5. The filter cover is attached to the wall. For this, mounting holes are provided.
6. Connect the pipes and turn on the water. Check joints for leaks.

All work on the installation of coarse filters is performed using adjustable spanners and gas switches. If you need to cut the pipe, then use a grinder or scissors for plastic.

Many manufacturers of household equipment connected to the urban water supply network do not provide a guarantee for manufactured products if a filter is not installed at the entrance of the water supply to the house / apartment. For quite some time now mechanical cleaning began to do, applying in addition mesh and cartridge filters in steam. The disadvantage is the need to change cartridges quite often and the impossibility of their reuse, whereas the mesh filters need to be washed once a quarter.
