A person who is in close contact with nature knows a simple truth. Water is the source of all life. It is water that is required not only by living beings, but also by the plants that surround us everywhere. Economical use of water for personal needs is not always possible due to a number of domestic and everyday conditions. Situations often arise when the water pressure in the public water supply of the village is very low, the water is supplied with a disgusting smell of hydrogen sulfide and is not entirely clear. Well, the most common case is a shutdown of water supply due to various breakdowns in the public water supply system. You can solve these problems by using a water tank on your site to accumulate water resources.

What to do

If the design of the storage tank does not provide outlets or the location of the pipes does not correspond to the selected connection diagram (for non-standard piping), you need to cut holes: for the supply pipe, outflow pipe and overflow pipe. The first can be installed at any level, since water flows into the tank under pressure when it is filled (but better in the upper part of the tank). The second is about 10 cm above the bottom, so that settled turbidity (sand, silt, dust) does not enter the system. The holes for the overflow pipe are prepared 2–3 cm below the installation site of the float valve; if it does not react, excess water will not spill out of the tank onto the floor or area. To properly maintain the storage tank, you will have to drain the water completely. Therefore, one more inspection hole is needed (in the lower part of the tank).
Organize natural ventilation. To do this, a cutout is made in the lid of the storage tank to prevent debris from getting inside the tank. A mesh alone is not enough - it will not prevent dust from entering.
Install the float switch. When the tank is filled, it will give a command to turn off the pumping device, and when the water level is low, to turn it on.

To protect the pump from operation in “dry running” mode, you need to install an appropriate relay if the design of the pump does not provide for this element of automation.

Cleaning filter. It is placed at the entrance to the storage tank and protects it from sediment from the main line (sand, rust, salt deposits).

When installing the tank yourself, you can use one pipe to fill it and supply water to the house. You just need to install shut-off valves and switch valves in a timely manner.

Why is an expansion tank needed?

It is well known to everyone from the school physics course that any body expands when heated, and liquids and gases increase in volume. Unlike gas, liquid is an incompressible medium, and if it is heated in a closed vessel, such as a boiler tank, this will lead to an increase in pressure inside it, since there is nowhere for it to expand. As a result, the tank walls may rupture.

Imagine a coolant heated in pipelines from a temperature of 20 ºС to 80 ºС. If you do not install an expansion tank in the heating system, then when the liquid medium is heated, the pressure in the network will increase greatly and water may break out at the weakest point. It's good to have a safety valve. The excess water will go through it, since it has nowhere else to go. If there is no valve, the coolant will simply break out at one of the connections.

An expansion tank is needed to accommodate the growing coolant as it heats up. At the same time, during cooling it returns back to the system.

In the case when the safety valve releases water, after cooling it cannot return it back and will allow air to fill the vacated space. This will lead to the formation of an air lock, which will prevent the system from working normally.

Service

Maintenance of the storage tank is recommended to be carried out annually. If the quality of water from the reservoir has noticeably deteriorated, more often, as necessary. The main technological activities are:

visual inspection of the tank, suitable lines, metal structures (when installing the tank on a support). Based on the diagnostic results, a list of necessary work is determined;
cleaning the tank. The walls of the storage tanks are smooth, and therefore all the turbidity accumulates at the bottom. The process of removing it is quite simple: the inspection hatch is opened, the water is completely drained, along with the dirt. For high-quality cleaning, it is advisable to pour the entire container thoroughly (under pressure) through the top hatch for 10–15 minutes (to remove remaining deposits) until clean water appears;
disinfection. The contents of the tank are not completely consumed, so stagnation of some of the liquid is inevitable. This initiates the development of pathogens, from which the storage container should be disposed of. A small amount of water is poured into it for 2-3 hours, to which chlorine bleach is added (as an option). After such exposure, you can begin to work: “wet” cleaning of the walls and bottom is carried out using brushes and scrapers with an extended handle. At the end of the procedure, the tank is emptied and washed several times with running water.

Scrapers and brushes should not leave scratches on the walls. These are potential areas where sediment accumulates and microorganisms grow. The cavity of the tank must be cleaned very carefully.

A complete list of maintenance work for a specific version of the water tank is indicated in the accompanying documentation for the product.

Water tanks for shower cabin

The summer heat periodically forces us to plunge into the coolness of the water element. Good for those who have a small pond or swimming pool nearby. However, most gardeners will benefit from a garden shower, under which you can experience the pleasure of pouring cool water no less than when bathing. By evening, the water in it will be warmed up, and under it you can already wash yourself from dirt and dust, just like in your apartment.

To build these amenities, you will need a flat-shaped water storage tank with a volume of 200-300 liters. The tank should be black. This will allow the water to be warmed more efficiently using sunlight. Next, you need to build a booth and create a small drainage to drain the water drained from the storage tank. Remember that the water will often be soapy and mixed with cosmetics. According to the requirements of the sanitary and epidemiological authorities, a modern shower must be equipped with a small sewer system to drain water into a common drain or a country septic tank. Any water tanks will be useful for household purposes. The technology for producing plastic tanks makes it possible to obtain a light-weight product that will not chemically interact with the stored substance, be it water or other liquid. Any pipes and threaded fittings can be easily installed into water tanks. The stiffening ribs that the large-volume water storage tank has prevent its deformation. By choosing water tanks made of plastic, you are purchasing a product that will serve you for many years, and will regularly perform the functions of accumulation and backup storage of liquids in all weather conditions.

Repair

Small leaks in the tank can be easily repaired on your own. These are typical malfunctions that manifest themselves mainly in the places where the pipes exit and where they connect with the pipes. You won’t need a welding machine, especially for plastic tanks. When eliminating defects yourself, it is recommended to use special putties and adhesives. The nuance is that not every product is suitable for these purposes - we are talking about water, which is also used for drinking and cooking.

When choosing a composition, you need to carefully read the instructions for its use. Experts recommend eliminating leaks in storage tanks using “cold welding”, two-component glue (“Poxypol”) or similar properties. To increase reliability, after applying the first layer, you need to apply a patch (for example, a piece of gauze) to the damaged area and re-process it. Manufacturers always indicate means that can be used to eliminate minor defects in the tank body; you just need to carefully read the instructions.

Selection of expansion tank

When choosing an expander, you need to take into account not only the presence of a pump in the system, but also:

Is the volume of the tank suitable for the size of the heating system?
What temperature can it withstand?
What material is it made of (and will this material be suitable for the coolant poured into the system).
Based on the cross-sectional dimensions of the inlet pipe, the tee connection fitting will be selected.

Closed systems are more efficient and also have a longer service life, since there is no contact of metal elements with air.

Advantages of plastic tanks

Plastic tanks are a worthy alternative to the usual storage tanks made of reinforced concrete and metal. This is confirmed by the advantages of plastic products:

The plastic tank is durable and easy to install

Tightness - plastic products are solid-molded tanks without a single seam, which guarantees their waterproofness.
Ease of installation - due to their low weight, plastic tanks do not cause difficulties either in transportation or in subsequent installation.
Chemical resistance - plastic does not react with any chemical compounds: neither with alkalis, nor with acidic, neutral or basic salts, nor with organic acids, nor even with sulfuric acid. Due to this, water does not lose its original physical and taste qualities during storage and does not change its chemical composition.
Durability – the average service life of a plastic tank is 40-50 years. Naturally, subject to compliance with operating rules and performing the necessary maintenance work.
Heat resistance - plastic containers retain their functionality over a wide temperature range: from -40 to +50 degrees.
Easy to maintain - a plastic tank can be cleaned with ordinary detergents as dirty formations form on the surface of the walls.

Advice. Standard plastic tanks cannot be called highly durable, so if you are looking for a container that is as resistant to mechanical deformation as possible, choose special models with thicker walls and additional stiffening ribs.

Installation of expansion tank

When installing an expansion tank, two circumstances must be taken into account:

When the container is filled with liquid, its weight will increase significantly, so the mount must be designed to withstand the load.
The unit must be provided with free access for maintenance (especially in open systems where water will need to be added periodically).

The installation method will depend on the materials used. This can be welding, flanges or joining plastic with a special soldering iron.

A fairly common mistake is when sealing materials are used that are not suitable for installing heating elements. For example, sealant for plastic windows - it is not designed to work with high temperatures, so after some time it will leak.

Tips for installing a heating system expansion tank:

The work is planned during the warm period, at positive temperatures;
It is imperative to install a safety valve;
The newest models of gas boilers have a small tank in their design; you should not rely only on it if the length of the pipeline is considerable. You need to recalculate everything and, if necessary, install an additional expander.
If you install a tap in a short section between the tank and the heating pipes, this will allow, if necessary, to dismantle the unit without disturbing the operation of the entire system.
