Common mistakes in installing a water supply system

The first mistake

Let’s start with a situation when a well is the source of water in a private house. In this case, it is very important not only to find water on the site and drill a well, but also to choose a pump. The portal has already written in detail about how to do this correctly..

The main mistakes are too low power or too powerful pump. In the first case, the water will flow in a thin stream if you turn on the washing machine at the same time, open the shower and the tap in the kitchen, for example. Will not push to the third floor of the cottage. In the second case, a too powerful pump will simply “kill” the well and “kill” itself, you will be left without water at all. So the correct calculation of the power of the borehole pump is simply necessary..

The second error

Introduce sewerage and water supply into the house through one hole in the foundation. Listen to the recommendations of JV 30.13330.2016 “Internal water supply and sewerage of buildings”. The rule states that there should be at least one and a half meters between the inlets of the drinking water supply and the discharge of wastewater horizontally. Yes, you can make separate units with overhead sleeves, as in the photo, but it is better not to risk it and place the water supply system away from the sewer. If you are going to repair one communication system, you will definitely not damage another.

Error three

Bury compression fittings directly in the ground or pour concrete over them. Such details of the plumbing must be located in a special well so that they have access. It is at the joints of pipes that leaks and other problems are most often possible, it is necessary to create conditions for possible repair.

Mistake four

Save money on pipe insulation. And it’s not just about the water supply system running down the street. Usually pipelines for hot and cold water run side by side, in the same shaft. And if they are not isolated from each other, then the cold water supply will simply heat up from the hot one. And that, accordingly, will cool down. In addition, thermal insulation will prevent the pipes from fogging up, there will be no condensation and puddles..

Fifth mistake

Do not install a circulation pump for hot water supply. It is necessary if the distance between the boiler and, for example, a bathroom is large enough. For example, a boiler room in the basement and a shower on the second floor. If there is no circulation pump, you will have to wait a long time until the “warm”.

Error six

Incorrectly install the bath, sink, toilet. It happens that the owners did not immediately clarify, they did not decide what model the plumbing would be, it does not clearly place the water supply and drainage. And then the owners or invited craftsmen try to fix the problem with additional corrugated pipes. They quickly become clogged with frozen soap and grease, and water from the kitchen sink and bath begins to drain poorly. You will have to use special pipe cleaning products at least once a month.

Mistake seventh

Do not put service taps that allow you to shut off the water supply during repair or maintenance. Such cranes are inexpensive, about 500 rubles, and they bring a lot of benefits.

Error eight

Incorrect slope of the sewer pipes. It should be 30 millimeters per linear meter if the pipe diameter is 50 millimeters, and 7 millimeters per linear meter for pipes with a diameter of 200 millimeters. That is, the larger the pipe, the smaller the angle of inclination towards the drainage side. Too great a slope will lead to the fact that the water will drain quickly, but large fractions will linger on the walls of the pipes. A small slope will cause frequent blockages and stagnant drains.

Error nine

Save money on siphons. Especially for the bath and shower. It is often difficult to change them, to clean them, there is a risk of an unpleasant smell. It is better to pay more for a high-quality siphon, with which there will be no problems for a long time.
