FAQ's

What is the specialty of ECOSTAR Stainless steel Water Tank compared to Concrete or Plastic Tanks?

1. Health Benefits:

Water stored in a stainless steel tank would not get contaminated because of chemical leaching as it happens when you install a HDPE, LLDP or PVC water tank.
Health experts all over the world have realized the ecological and health benefits of using stainless steel in the water disbursal process. Water tanks are now being made with stainless steel and for all valid reasons.

2. Corrosion free:
The very first reason is that stainless steel is a corrosion-free raw material.
It would not corrode due to temperature or weather fluctuations.

3. Eco-friendly:
Environmental changes do not affect stainless steel so that means the Stainless steel Water Tank is an eco-friendly.

4. Highly durable:
Stainless Steel material and highly durable as well. When you install a stainless steel water tank, you can be sure of the fact that it will remain good for at least 15 to 20 years with Great look and appearance like brand new 

5. No Bacteria, Fungus, Algae:
Talking about purely and cleanliness, water stored in any PVC, HDPE, LLDP,  Concrete  or any other metal tank gets affected by leaching and other environmental reasons but stainless steel is a sturdy material, when you install ECOSTAR water tank, you will get pure and cleanest water.

6. Easy Tank Cleaning:
Easley can clean the tank by opening drain valve located at ground level. Not required to enter inside tank confined space.
Beyond that – Less maintenance, cost analysis cheaper for long run, Great look and appearance even after 10 years it will  look brand new , No smell or taste changes.

How to resolve hot water problem in summer?

ECOSTAR stainless steel water tanks are made with Bright Annealed (BA) surface finished ASTM A240 Gr. 304/316 Stainless Steel coil mainly from JINDAL STAINLESS LIMITED (JSL) the BA surface finish reflect part of temperature and keep storage water not be over heated, In fact, it is one of the best stainless steel water tanks that is made up of premium grade stainless Steel.

The question would be bothering a large number of households harsh in summer season in the months of April to June. In these months, the temperature crosses 40°C and people don’t get any respite from the heat even after bathing because the water that comes in their bathrooms is equally hot. Plastic or PVC water tanks on their rooftops even concrete tanks do not stop or save the water from Sun’s heat in the summer season.

Do mirror finished stainless steel overhead water storage tank attract lightning?

No, as per “The Atlanta Journal: The presence of metal makes absolutely no difference where lightning strikes. Height, pointy shape and isolation are the dominant factors controlling where a lightning bolt strikes.

In ECOSTAR last four years history no single  customer reported about lightning, but we always recommend Safety Fist, If your building is located on topmost highest elevation please do proper separate grounding for tank .

How common size and thickness should a stainless steel domestic tank be?

How long can a stainless steel water tank last?

A stainless steel water tank from Select Water Tanks has Generally a minimum life of 30 years, its depends what quality of water you store, pH value, Water Hardness (ppm), TDS (ppm) ECOSTAR recommend always choose correct thickness tanks based on your water quality, minimum 0.6mm thickness for open well and 0.8mm thickness for bore well water storage for 1000L tank, the corrosion-resistance properties of Stainless Steel mean your tank will not only last for a long time, but it will always look brand new.

What metal is best for water tanks?

Stainless steel is an excellent material for a water tank.

If it’s relatively pure water, Grade 304 stainless, which contains (in wt.% of alloying element): 18 – 20 Cr, 8 – 10.5 Ni, ≤ 0.08 C, ≤ 2.0 Mn, ≤ 0.75 Si

However, having said that, if the water contains an appreciable amount of chlorides, then I would suggest use a Grade 316L stainless, which is resistant to attack by chlorides. Grade 316L has the following composition (in wt% of alloying element):

16 – 18 Cr, 2 – 3 Mo, 10 - 14 Ni, ≤ 0.03 C, ≤ 2.0 Mn,  ≤ 0.75 Si

Grade 316L is excellent in a range of atmospheric environments and many corrosive media - generally more resistant than 304.

Before comparing important differences between PE, HDPE, LLDP and stainless steel water tanks, it is important to understand that there are different grades of stainless steel. Grades are often represented by different numbers.
Chromium is a base element found in stainless steel that prevents corrosion. To resist the corrosive effects of salty sea water, harsh acids and the like, the chemical element molybdenum needs to also be added. Molybdenum is found in the 316 Stainless Steel and is used in surgical instruments and stainless steel implants.

While plastic and concrete tanks are a breeding ground for bacteria and mould, stainless-steel tanks are resistant to both. In addition, stainless steel is a non-porous material that will not allow outside elements to enter and contaminate the water supply.
Stainless steel is not only a top-quality and durable metal, it is also the safest option for use in your home. Stainless steel emits no toxins and does not react with ingredients.

What pH is bad for stainless steel?

Higher pH reduces the stability of the oxide films and accelerates the dissolution process of the oxides. With increasing pH, the corrosion rate decreases, being highest at pH 4 and lowest at pH 9.

Are stainless steel water tanks better?

Stainless steel water tanks offer greater resistance to crevice corrosion, cavitation, and wear and tear in pure and contaminated waters. This material is also heat resistant and doesn't get affected when exposed to harmful radiations. Moreover, stainless steel tanks are less likely to crack, rust or freeze.

Do stainless steel tanks rust?

The term “stainless steel” (sometimes known as “inox steel”) comes from the word “inoxydable.” Unlike other steels, it will not corrode, rust, or discolour when exposed to moisture.

Are stainless steel water tanks safe?

Stainless steel water tanks guarantee safe and clean storage of water as their interior does not breed algae. Compared to their plastic variant, stainless steel tanks possess a longer service life. They are impact, fire, and corrosion resistant.

What can damage stainless steel?

Common causes of stainless steel corrosion include chlorides, hydrochloric acids, sulphuric acids, iron or carbon steel contact, and high temperatures. There are over 150 grades of stainless steel, and some are more prone to corrosion than others.

How long will stainless steel last?

Because of their durability and longevity, stainless steels are typically in use for many years before they become available for recycling. The average lifespan is estimated to be around 30 years, but there are examples of stainless steels in use for a century and beyond.

How do you maintain stainless steel?

One of the best ways to clean stainless steel is to use a cloth rinsed with warm water and dishwashing liquid. Follow this up with a rinse down with plain warm water, wipe it off with an absorbent cloth

Is stainless steel good for long term water storage?

Water is often stored in large tanks for use in emergencies, drinking, and manufacturing. In the past, plastic tanks were often the standard for water storage. Stainless steel tanks are now widely known as the best option for storing water

What are the disadvantages of steel tanks?

Choose correct thickness based on which quality water you are going to store, Hardness, pH and TDS

If you don't buy from a reputable supplier, there is a risk that they could corrode over time.

Initial cost will be high.

How do you protect stainless steel water tank from corrosion?

External Clean the Tank with the soft cloths with light soap solutions every 4 moths

Test your water and treat your water, Control Water Hardness (ppm), TDS (ppm), pH value

Keep and do surveillance inspection tank internal every 6months if any sediments clean by Rinsing. You shall be drain out tank monthly by drain valve

Never use or contact any type of acid or salt on stainless steel.

Keep ECOSTAR Stainless steel Gr.304 Tank from Sea breeze (Shore wind) or shore environments.

Avoid bimetallic (Galvanic) corrosion.

Do not do any steel cutting and welding jobs nearby SS tanks without proper covering or isolation of Tanks.
