Do-it-yourself plumbing in a private house


The water sup­ply sys­tem has already firm­ly pen­e­trat­ed the minds and plots of the own­ers of vil­lage hous­es and coun­try cot­tages. This is an inte­gral attribute of a com­fort­able life: with run­ning water, show­ers, wash­ing dish­es, cook­ing become a pleas­ant expe­ri­ence.

Installing it your­self is not an easy task, but you can do most of the work alone.

We develop a water supply scheme

In fact, there are plen­ty of plumb­ing schemes, but there are two dif­fer­ent meth­ods for con­nect­ing con­sumers:

  • Trin­i­ty inclu­sion.
  • Col­lec­tor or par­al­lel con­nec­tion.

For res­i­dents of small pri­vate hous­es, a ser­i­al con­nec­tion will meet their require­ments, the plan for such water sup­ply is sim­pler. From the source itself, water in order goes from one con­sumer to the next from one pipeline with a tee out­let (1 inlet, 2 out­lets) for each con­sumer.

Such a switch­ing scheme is char­ac­ter­ized by a lack of pres­sure at the last con­sumer, dur­ing the launch of the pre­vi­ous ones, if sev­er­al such links are involved in the chain.

The col­lec­tor inclu­sion plan looks fun­da­men­tal­ly dif­fer­ent.

First­ly, when mak­ing such a con­nec­tion, you will need a col­lec­tor. From it, a water pipe is laid direct­ly to each con­sumer. There­by you will be able to cre­ate more or less the same pres­sure in any link in the pipeline chain. Please note that a ser­i­al con­nec­tion will cost you more.

Any water sup­ply sys­tem con­sists of a well, a pump, a hydraulic accu­mu­la­tor to pro­tect the pump. And if desired, a fil­ter or sev­er­al fil­ters before or after the accu­mu­la­tor.

house plumbing diagramThere are sev­er­al types of plumb­ing pipes, the most com­mon mate­ri­als for them are polypropy­lene, poly­eth­yl­ene (crosslinked), steel. The most expen­sive ones are made of cop­per, because they last the longest.

In case of mount­ing them, you will have to call a spe­cial­ist. The best choice is polypropy­lene in terms of price-qual­i­ty ratio. Please note that plas­tic as a mate­r­i­al is absolute­ly not suit­able, as it releas­es harm­ful ele­ments into the water.

The diam­e­ter of the pipe depends on the length of the pipeline of a pri­vate house: from 30 meters, mate­r­i­al with a diam­e­ter of 25 mm is enough, if more than 30 meters, then 32 mm will do, and in the case when the length is less than 10 meters, the diam­e­ter varies with­in 16–20mm.

Next on the list you will need a sub­mersible pump, as it is more durable and more effi­cient than a pump­ing sta­tion. The height of the pump is mea­sured along with the hose and then they are con­nect­ed by a thread­ed con­nec­tion. The pump can be placed in any posi­tion on stain­less steel cables. It hangs from the top of the well.

Water from the pump enters the fil­ter to the accu­mu­la­tor, which is the next ele­ment of the cir­cuit. It cre­ates a sta­ble pres­sure and allows you to turn the pump on and off as need­ed.. The vol­ume depends on the amount of water con­sumed.

The water is again fil­tered and divid­ed into two streams: one of them will go to the boil­er and heat up, and the sec­ond will remain cold in the col­lec­tor.

It is nec­es­sary to mount shut-off valves up to the col­lec­tor, as well as install a drain cock.

The pipe going to the water heater is equipped with a fuse, an expan­sion tank, and a drain valve is also installed. Same the tap is mount­ed at the out­let of the water heater, and after that the pipe is con­nect­ed to a col­lec­tor with hot water and fur­ther divorced at all points in the house.

Boil­ers may vary. Water can be heat­ed by gas or elec­tric­i­ty. A gas instan­ta­neous water heater dif­fers from an elec­tric one in that the water is con­stant­ly heat­ed.

Plumb­ing deserves spe­cial men­tion.. The process of con­nect­ing the toi­let begins with the instal­la­tion of a cor­ru­gat­ed pipe, which is lubri­cat­ed with sil­i­cone at the junc­tion. Next, the reli­a­bil­i­ty of the con­nec­tion is checked, holes are drilled into which the dow­els are insert­ed. The toi­let is attached to the cor­ru­ga­tion and twist­ed.

Do-it-yourself installation

The water sup­ply from the well is divid­ed into two types: sum­mer and win­ter:

  • Sum­mer view of the sys­tem being laid above the ground – rub­ber hoses are con­nect­ed with adapters and thus the required length is ensured.
  • Win­ter view of the water sup­ply works in any sea­son and it is laid either below the freez­ing of the soil, or above, but with insu­la­tion.

Before con­duct­ing water from the well, it is nec­es­sary to make a cais­son for it. You can go down into it and it will pro­tect the well from dirty water.

The cais­son is made of con­crete rings or oth­er mate­ri­als.. If its bot­tom and the pipeline are above the freez­ing of the soil, it does not make sense to use a cais­son in the event of a pipe break.

Con­nect­ing to the cen­tral high­way requires a sig­nif­i­cant invest­ment in the ear­ly stages, mean­while, par­tial­ly reliev­ing of exca­va­tion and instal­la­tion of a sep­tic tank. You can find out infor­ma­tion about the near­est high­ways in the ZHKO.

To increase the water pres­sure in the pipeline, it is nec­es­sary to embed the pump into a pub­lic water sup­ply pipe or install a pump­ing sta­tion with a hydraulic accu­mu­la­tor.

Usu­al­ly in apart­ments it is com­mon to mount pipe wiring to the wall.. Sew­er pipes are held on clamps attached to the wall. The dis­tance that is mea­sured hor­i­zon­tal­ly from the clamp to the clamp must be set to less than 10 pipe diam­e­ters.

You can use either met­al clamps with a rub­ber seal (rigid mount), or with­out seal­ing so that the pipes can move freely (rigid-float­ing mount).

internal wiringInter­nal wiring is a more advanced rout­ing methodbecause it reduces noise and looks bet­ter. It is pos­si­ble to lay pipes in con­crete or strobe, observ­ing slopes and seal­ing gaps.

Polypropy­lene pipes are weld­ed in two ways: sock­et and butt. It should be car­ried out at a pos­i­tive ambi­ent tem­per­a­ture. It is impor­tant to remem­ber that pipes and fit­tings are of the same com­po­si­tion and are clean. Also, do not cool the pipes after con­nect­ing with water.

Dur­ing sock­et cook­ing, both parts are heat­ed with a spe­cial heat­ing device, then col­lect­ed and cooled.
