The Importance of Regular Water Tank Cleaning

If you have a water tank on your property, it is important to clean it regularly. A dirty water tank can lead to all sorts of problems, from decreased water pressure to contaminated drinking water. In this blog post, we will discuss the importance of regular water tank cleaning and how to go about it!

How do you clean a tank?

Primarily, you should always start by draining the tank completely. This can be done with a pump or simply by opening the drain valve. Once your tank is empty, use a pressure washer to thoroughly clean out all the sediment and build up inside. Make sure you also give extra attention to areas around fittings and pipes where sediment accumulates. After you’ve thoroughly washed the inside of the tank, it should be refilled and treated with a water-tank cleaning agent such as chlorine or a specialized product for water tanks.

How often should I clean my tank?

This depends on several factors such as the type of tank, its size, how often it is used and other environmental factors. Tanks should be cleaned at least once every two years but if you’re using your tank frequently then we recommend cleaning it more regularly.

How much will it cost?

The cost of water tank cleaning can vary depending on the size and type of tank, as well as where you live. It is best to hire a professional cleaner who can advise you on how often your tank should be cleaned and what products are needed for safe cleaning.

How much water will I lose?

The amount of water you lose during tank cleaning will depend on the size and type of your tank. It’s a clever idea to fill up an extra tank with some of your tank’s clean water before draining it for cleaning, as this can be used to refill the tank once it is finished being cleaned.

Do you have to get inside my tank?

This depends on the type and size of your tank. A professional cleaner will not need to get inside the tank but may use specialized equipment such as a remote camera to assess its condition.

Why does my Rainwater get smelly?

Rainwater can sometimes become smelly due to the build-up of organic matter such as leaves and twigs. Regularly cleaning your tank is essential to keeping it free from odours and ensuring the safety of your drinking water.

What are the hazards of tank cleaning?

If done incorrectly or without the right safety equipment, tank cleaning can be dangerous. The water you are draining may contain harmful bacteria such as legionella and it is important to wear protective clothing while cleaning your tank.

Which chemical is used for tank cleaning?

Chlorine is the chemical most used to clean water tanks. This can be added directly to the tank or dissolved in the water before it is added. When using chlorine, always follow the manufacturer’s instructions and use caution when handling this product.
