Water tanks are often located in difficult-to-access spaces and many were installed before today’s standards and current legislation came into place. We did not always know as much as we now do about the importance of water quality and there are a large number of existing water tanks that do not meet the required safety standards.
Water tanks are subject to corrosion and scaling, and while this can be treated if caught early, sometimes replacement is the only sensible option. Sometimes it is necessary where the tank is used to supply drinking water.
All tanks that we replace meet the safety features required under WRAS and HSE guidelines. We provide a full installation service and will size your new water tank to meet the needs of the building population; balancing water demand with the necessity of reducing stagnation. On completion, Aqualogic will carry out a tank chlorination, followed by tank tests, as required. A monitoring and maintenance programme will extend your guarantee and protect water users.
The frequency at which you will require a TMV check will depend on factors such as water hardness and how often it is used – we conduct regular maintenance checks to ensure that your TMV continues to operate at the optimal temperature of between 39-43°C. During servicing, we will check the operation of the valve and clean, descale and disinfect the strainers. Regular maintenance is vital not only to ensure that your TMV is still working, but to guard against any dirt that could lead the growth of Legionella and other waterborne bacteria. Legionella grows and multiplies in water temperatures that are between 20 – 45ºC, but is killed when temperatures exceed 60ºC. Naturally though, using water at this high temperature would be unsafe for skin contact and would result in scalding – once water hits 50 ºC it takes significantly less time in contact with skin to result in third-degree burns. By installing a TMV, water can be stored at this high temperature known to prevent the growth of Legionella, but delivered safely to the skin once is passes through a cold water system just prior to reaching the tap.
