Dewater the Tank
You have to drain all the water first by opening a tap outlet to let the water out. You can also use hosepipes so you can direct the water to a safe area without causing erosion. Use a sanction machine or dry vacuum cleaner to dry the tank completely.
Mix the Cleaning Product
Make a cleaning mixture by adding some mild and laundry detergent in hot water. This is helpful in sediments removal and getting rid of the residues from the tank.
Cleaning the walls
Start by scrubbing the walls of the tank thoroughly using the cleaning mixture and a bristle brush. Do it around all the walls applying more pressure as you move your hands horizontally and getting rid of all the sticky dirt.
Clean the inside of the tank
Scrub the inside of the tanks thoroughly to get rid of the sediments and scum. You, however, must ensure that you have the best resin for best results and not only that, make sure that you have prepared the tank well for cleaning. Fill your power washer with the cleaning mixture (the one you made from water and detergent). If you realize that the solution is getting harder with time, add acetone to dissolve
Hold the washer in the best position and distance that will work for you in removing all the dirt and sediments. Repeat the procedure until you are satisfied with the results. Note that you should be wearing protective gear such as gloves and glasses throughout the process.
Rinsing dirt from the dark
Now that you have already scrubbed off the sediments from the floor and wall of the tank, it is time to rinse the tank with purely clean water. You can use hose and pipes for this. The other option is filling the tank with hot water, wait for it to stand for some time before draining it and repeat the process until all the sediment and detergent is swept off.
Drying the tank
It is time to get rid of any water residues, and the best way to go about it is using a vacuum to dry it off until there are no traces of dirty water.
There, you have a clean water tank, and you can now refill it with fresh water. For more info contact GRP Panel Water Tank UAE or call us at +971 4 252 2966

- Ensure the team cleaning the water tank(s) are suitably trained, certified and have the correct PPE equipment.
- Check the Risk Assessment prior to work to familiarise technicians and Responsible Persons with hazards associated with the task, asset(s) and how to reduce or control any risks identified.
- Inform / communicate with all building users that cleaning work is about to take place (use signs as appropriate to reduce or prevent usage of showers / taps during work).
- Photograph the condition of the water tank before commencing work.
- A pre-disinfection cleaning flush is required.
- The tank inlet must be isolated so that the tank can be drained and inspected.
- Any booster pumps associated with the system / tank should also be isolated from mains power supply.
Emptying and cleaning the tank:
- Empty the tank (to drain or as per the waste disposal licence as applicable).
- Take a photo of the empty tank for the Log Book.
- Tank entry – if entry is necessary, then two technicians must be present and confined space safety rules, regulations and procedures must be followed.
- Cleaning – manually scrape clean all internal surfaces and vacuum the floors and walls with a wet vac. All visible dirt and debris should be removed. Any signs of damage, corrosion, scale, flaking, black spotting, and deficiencies (e.g. missing rodent screens, cross flow vents etc) should be noted.
- Refill and flush the tank with fresh mains water checking for leaks during the refill process.
Disinfection and chlorination:
- Note pH of the mains water.
- Chemical disinfection is carried out after cleaning by chlorinating the water in the tank to the specified concentration in mg/litre (ppm) of free residual chlorine.
- Determine the tank volume, required concentration, minimum contact time and dose per m3 in water.
- Use a chlorine test kit to check the Sodium Hypochlorite and do not add chemical to the tank until the tank it half-filled with water.
- Add further Sodium Hypochlorite if required and re-test to achieve 50PPM free residual chlorine in the tank. Chlorine may be added at 0.5 litres per m3 and mixed in the tank. The concentration of free chlorine is affected by pH. Do not use in systems with a pH greater than 8.5 and adjust the contact time according to the approved Method Statement.
- Once the required level of chlorine is achieved and maintained, the outlet of the tank may be opened to allow chlorinated water to flow around the system
- Chlorinated water flows to all outlets and needs to be checked by a technician by successively opening taps and showers. Use the most up to date Legionella Risk Assessment (or Water Hygiene Risk Assessment) to identify all sentinels (furthest points) and remaining outlets.
- Where testing all taps / showers is not possible or practical, as a minimum, test the sentinels at the end of each pipe-run along with a proportionate number of outlets along each leg.
- Ensure that 50PPM is achieved at all sentinels for 60 minutes or at least 20PPM for 120 minutes.
- If you believe the water tank will run dry whilst pulling water through the system, turn off the outlet valve to prevent air from entering the system and refill the tank half-way before adding in another dose of chemical and completing the fill of the tank.
- If disinfecting hot down services, allow water from the tank to flow to the calorifier.
System recommissioning:
- After the required contact time, the chlorinated water must be neutralised using Sodium Thiosulphate (non-hazardous) if the disinfection is >5PPM. You require 2g of Sodium Thiosulphate to dilute 1PPM per 1,000L of water.
- Dissolve with tepid water and dose the tank. Allow to flow throughout the water distribution system and check that water is no-longer chlorinated using Starch/lodide papers.
- Drain the tank to half-way by opening the drain valve or by using a pump and pump out. The ball valve is opened to allow the tank to be refilled with fresh water. Ensure the ball valve closes correctly so that the tank is in no danger of over-filling.
- Once the system has been flushed through or partly drained the TDS should be measured and the levels should be equivalent to the incoming mains water supply (TDS within 5%). Also, measure the concentration of free chlorine remaining in the tank. It should be between 0.5 and 0.1PPM.
- Record the levels achieved in the Comments section of the Clean & Disinfection Report or Log Book. When levels are acceptable the warning labels should be collected from all outlets and the system returned for use.
Final steps:
- Photograph the condition of the water before reapplying the tank lid.
- Complete a Disinfection Label for each tank and indicate if down services were included in the process.
- Sign and attach a label to each tank and remove the old sticker or place over previous one.
- If hot down services were disinfected, turn on the calorifier and ensure the temperature of the water is a minimum of 50°C on the return, or 55°C in a healthcare setting. The calorifier flow should be measured at a minimum of 60°C. Add a service sticker to the calorifier to show the details of the disinfection.
- Ensure all equipment is removed and all valves are open on the tank and (if applicable) the calorifier (except Drain Valves).

The answer is that the the upfront advantage of having a hot water tank over having a tankless option is the price tag, which can sometimes be as much as 75% less expensive. The downside is the utilities are considerably different.
It depends on the cost of the utilities in your area, but often times it’s about 1/3 of the cost of utilities going from a gas tank to a gas tankless. If you’re planning on moving in the next few years, I would say probably just put a tank in because you’re not going to recoup your money. In order to actually make a profit you’ll need to use it for a period of, let’s say ten years at least. However, the life span of tankless can be as long as 20 years, or even 25 depending on the water in your area.
Something else that we get asked about quite often is putting in an electric tankless to replace their electric hot water tank. Electric tankless versus gas tankless is not a very good option in any way, shape or form. They’re expensive and they are maybe10% more efficient than an electric hot water tank, so totally not worth it.
On the comfort side of things, there’s a difference between how the two operate. A tank can almost run an unlimited number of faucets, so let’s say you have four bathrooms in the house and two kitchens. You can turn on everything in the house BUT it will quickly drain the tank down. You could probably run it for about ten minutes and the whole thing will be drained.The advantage of the tank is the fact that you have an unlimited amount of faucets that you can run simultaneously. The problem is that they run out quite quickly.
The tankless option has the opposite problem. It can run a limited number of faucets, sometimes as low as two and as high as six or seven, again depending on the area of the country that you’re in. If you’re in the southern United States or somewhere where the ground water is warmer you’re going to get more hot water that comes out of your tap because the starting temperature is higher.
If you’re in the northern states, you’re going to have less output out of it because the starting temperature of the water is colder. Everything in general is going towards tankless water heaters, as a general rule, so probably in 10, 20 years they’re going to be the dominant option.

Advantages:
Disadvantages:
- Rainwater tanks are fairly easy to maintain overall, as it allows you to utilize a great, renewable energy resource that is extremely useful to all. Drinking water is not quite so easily renewable, so this really helps lower the wastage so prevalent in most societies.
- Rainwater harvesting helps reduce the overall water bills, giving you a chance to be free of paying greater sums to water utility companies. This is extremely useful for a lot of smaller businesses and families, as it allows them to lower their overall bills. On a greater, industrial scale this works even better, as it allows harvesting rainwater in much larger quantities.
- It makes it great for irrigation purposes as rooftops can work as an area for catching the water, which can then be linked to a harvesting system and water tank or rain barrel. This makes gravity the driving power here, lowering the use of fossil fuels.
- It helps reduce the overall demand of ground water, as most cities take a serious toll on the drinking water of the areas around them. This greatly helps with the natural balance between our population density and the local biosphere.
- It helps reduce erosion and floods, as rainwater can be contained in a way that doesn’t hurt the environment.
Disadvantages:
- Rainfall can be pretty unpredictable in some areas of the world, so this could seriously inhibit the usefulness of a system like that. You should not depend solely upon rainwater for your water needs, especially in areas where such rainfall is limited.
- The initial costs can be steep for some households, depending on the system and how much benefit can be derived from its use. Much like solar panels, the costs can be negated for the next ten to fifteen years, largely depending on the system itself and the rainfall of your area.
- Regular maintenance is required for rainwater as the tanks can get mosquitoes, algae and worse if you leave them unattended for far too long.
- Some roof types may be a problem for water tanks, as they can allow animal droppings, insects and even chemicals to seep into the water if used for plant irrigation.
- You can also have a limit to water tank storage capacity (sometimes due to space available) that restricts the amount of water you can use. After all, during a heavy, pouring rain the system may not be able to handle the volume released by local weather.

1. Guarantee
When Tank Reline takes on a job to re-line a water tank, the work is guaranteed, therefore in the unlikely event the tank needs follow-up care, Tank Reline would be on hand. The majority of manufacturers of new water tanks in the UK can only offer a 12-month guarantee. Tank Reline is unaware at this time of any UK manufactures/installers that offer longer than 12 months warranty for new water tanks. Once the 12 months has passed, the client is left to manage any after-care themselves (ultimately the system is not covered under any warranty and the client is left with the problem).
2. Save Money
Replacing a water tank in its entirety can be a demanding job, which comes with huge expense. Opting to reline instead of replacing will save you money and provide you with a guarantee.
3. Save Time
A complete replacement tank is a very big job, and one that should not be undertaken lightly. By opting to reline the water tank instead of replacing you keep disruption to your business to an absolute minimum and you can expect the work to be completed in a much quicker turnaround.
4. Water safety
When Tank Reline undertake a re-line, a full on-site assessment will be completed using the latest technology on a PDA based system which is instantly reported back to our project team achieving a prompt response. This is because we want to ensure we have advised you on the best and most appropriate course of action. We also offer a range of services which run hand in hand with relining a tank. For example, Tank Reline offers a clean and disinfection/chlorination service upon completion of a reline which means the tanks are cleaned in accordance with the latest health and safety guidelines, giving our clients additional peace of mind and results in our client not needing to return to site to commission the system themselves. This is one thing most of our competitors do NOT offer (so please be aware of this when reviewing quotation proposals). Let us do all this for you, leaving you with your other water treatment services for your client instead.
5. Protect against corrosion
Unfortunately, the way in which potable steel water tanks are designed they can be susceptible to general wear and tear and corrosion. Although this is inevitable during the life cycle of a water tank, the exclusive coating Tank Reline use when relining tanks fights against this corrosion because of its high-build solvent free ingredients.

Here are the 5 steps to follow when relining a water tank;
First step:
Structure: The most important factor when relining a water tank is firstly to assess the structural integrity which requires a site inspection before works commence. Tank Reline has a breadth of experience working with a variety of structural tanks of all sizes, therefore are well equipped to take on any job., of any size.
Second step:
Preparation: Preparation is the crucial element to all tank reline jobs. If the preparation is completed incorrectly or inadequately then it is highly likely the tank reline will not work. Tank Reline has been drafted in on a number of occasions to resolve a variety of issues where inexperienced contractors have failed to undertake the works correctly.
Third step:
Application Process: It is vitally important to follow the step-by-step application requirements when relining a water tank. For example, the usual procedure is; stripe coat of all joints and shapes edges – first full coat (in line with the manufacturers guidance) – second coat – final coat.
Fourth step:
Quality: Upon completion of the tank reline, it is necessary to conduct quality checks to ensure film thickness has been achieved to the specification required. On many occasions Tank Reline has been contracted to re-do a job where a previous, inexperienced contractor has failed to ensure the film thickness and single coat application are correct. This double error will always cause a breakdown in the tank relining process and the job will more than likely need re-doing.
Fifth step:
Guarantee: Various contractors will offer some sort of guarantee, so always ensure you fully understand the guarantee on offer and what it covers. Quite often, the guarantee provided includes unfair conditions and exclusions, or worse, elements of the job are not covered once the issues are raised and disputed.
Tank Reline launched its Gold Package warranty in 2017, which includes an annual site visit by a Tank Reline specialist engineer to inspect the water tank reline and report back to the client with findings. This means, Tank Reline works closely with the client throughout the guarantee period. The majority of our competitors simply offer a promise on a piece of paper, frequently filled with conditions and exclusions which are never accountable if there is a dispute. This is where Tank Reline pride themselves on their customer service and hope this service sets them apart from their competitors.
