How Do You Drain a Cold Water Storage Tank?

Draining your cold-water storage tank is the first stage of any water tank replacement project. To begin, the tanks inlet must be isolated, along with any booster pumps associated with the system. After this, the water can be safely drained out of the tank via the drain or pumped out using a submersible pump. We recommend this is done into a designated foul drain that has been checked to ensure it can cope with the volume of water.

How Often Do Cold Water Tanks Need Replacing? 

As a rule, the average life expectancy of a of cold-water storage tank will be somewhere between 10 and 15 years. This can differ significantly depending on the size and design of the tank, as well as the system associated with the tank and its location. However, regardless of these factors, regular and thorough maintenance can help tanks to outlast their expected lifespan and remain fit for purpose for significantly longer.
