Frequently Asked Questions About Polyethylene and Plastic Tanks

– Is the strength of single-layer polyethylene tanks less than three-layer and multi-layer tanks?

No. The only difference between single-layer or colorless tanks and three-layer or multi-layer is the presence of a layer mixed with colors such as black between the layers to act as a visible light filter inside the tank to prevent algae growth and proliferation. As a result, the strength of colorless or single-layer and three-layer tanks does not differ from each other.

– Can we bury polyethylene tanks?

Polyethylene tanks are generally made and used in two ways. Either they have to be placed on the ground or they have the ability to be buried underground, which is called a polyethylene burial tank. Generally, day tanks have a softer and thinner body, however, up to 25% of the height of these tanks can be placed underground. On the other hand, underground or burial tanks can be completely buried under the ground (the instructions for installing burial polyethylene tanks will be at your disposal at the time of purchase).

– What happens if the polyethylene tank freezes?

If the tank is half full, it is unlikely that it will break due to freezing. In this case, the walls only inflate due to ice pressure. A tank starts to freeze only in the constant and intense cold of a few days. Before the cold season, the tank pipes must be covered or emptied of water. Because the low volume of water inside the pipes will start to freeze sooner and can cause the pipes to explode. If freezing your tank is a concern for you and you haven’t bought the tank, order your tank in a black and white exterior, and if you have purchased it, you can equip your tank with a heating system (such as aquarium heaters) or insulation or Place in an insulated chamber. Installing tanks in underground chambers both keeps the water cooler in the summer and prevents the tank from freezing in the winter.

– Do the tanks have connections (inputs and outputs) or accessories?

By default, all repositories have no input or output. In this way, the tank will be drilled exactly according to your order. At the time of order registration, dear customers can inform us of the appropriate size for inputs and outputs so that they can be installed in the factory warehouse and on the tanks before sending. They also provide additional accessories for installing pipes at the customer’s request.

– What is the weight of polyethylene tanks?

Polyethylene tanks are generally much lighter than other tanks, and this is a very important advantage for them. A heavier tank isn’t always necessarily better. The novelty of the raw material (non-use of recycled materials) is more important both in terms of water hygiene and tank strength. The heavy tank made of recycled materials is both unhealthy and dry and brittle.

– Can the growth of algae in the tank be a matter of concern?

Note that algae (green color) is different from the deposition of suspended matter (dark and brick color), algae after decay and decomposition by anaerobic bacteria can cause bad odor and taste of water. Also, the growth of algae accelerates the penetration of light into the tank as much as possible, so by placing the tank in a lighter and darker place or using three-layer tanks, the growth of algae inside the tank can be prevented.

How long does a polyethylene tank last?

The life of a tank depends on a variety of factors. For example, the quality of the raw materials used in its production, product design, the material stored in the tank, the location of the tank, the constant or moving position of the tank, and the amount and intensity of sunlight. Note that these are just a few of the issues that can affect the longevity of a polyethylene tank. Generally, high-quality polyethylene tanks used for water storage can have a useful life of 10 years or more.

– Do your tanks have a sanitary permit and are suitable for water storage?

Yes, our tanks are made with resins approved by the Ministry of Health and the Food and Drug Administration. All the tanks that have been placed on the Pars Reservoir site have the ability to store water for drinking and sanitary purposes, and they also have a health apple logo. When buying water tanks, be sure to ask the seller for the Apple Health Code and ask the Food and Drug Administration’s website. Unfortunately, some fake labels or labels are used to deceive customers.

– Will there be a change in the taste of the water stored in the water tank after a while?

Your water storage tank must be connected to the plumbing so that the water can flow from time to time, as the taste of the still water will change due to the reduction of oxygen. If your tank is not connected to the piping, you can fill the tank halfway with water to solve this problem, and occasionally return the water inside the tank to the inside of the tank with the help of a pump to increase the dissolved oxygen in the water. .

– Can cracked or broken tanks be repaired by plastic welding?

In general, yes, polyethylene tanks can be repaired through polyethylene welding. But there must be conditions for this, and whatever
