Cold Water Tank Installation & Upgrade
Get the Story Fast – Watch the Case Study Video
When a customer upgraded their pump system, they needed a larger water storage tank to meet the increased demand and ensure reliable performance. The customer’s existing cold water tank no longer provided sufficient capacity, making a full water tank replacement essential. Metro Plumb Walton-on-Thames were tasked with removing the old tank, constructing a new support platform and installing a larger 75-gallon coffin tank. By adapting the existing setup and reconfiguring the pipework, the team delivered a practical solution that improved storage capacity and supported the customer’s upgraded system requirements.
The Challenge: Insufficient Water Storage Capacity
The customer needed a larger system that could support their demands while maintaining a consistent and reliable water supply throughout the property. The project presented several challenges. The existing tank had to be removed safely, and the larger tank required a completely new support structure. In addition, the existing pipework layout was designed around the previous installation, meaning alterations would be required to integrate the new cold water tank effectively and ensure the upgraded system operated correctly.

The Solution: Cold Water Tank Installation
To meet the customer’s needs, Metro Plumb Walton-on-Thames carried out a full cold water tank replacement, removing the existing tank and preparing the loft space for a larger installation.
The new water storage tank selected for the project was a 75-gallon coffin tank, providing significantly greater capacity to support the upgraded pump system. As the larger tank needed additional structural support, the team constructed a bespoke timber platform designed to safely accommodate the increased size and weight of the installation.
Once the platform was complete, the team installed and secured the tank before adapting the existing pipework to suit the new layout. They ensured all connections were compatible with the upgraded system and integrated the new water storage tank with the property’s plumbing infrastructure for efficient operation.
Following installation, all pipework connections were completed, and the system was fully tested and commissioned. This comprehensive water tank replacement and installation ensured the new system operated safely and efficiently, while also providing the additional capacity the customer required. As a result, the upgraded solution not only met their immediate water demand but also helped future-proof their water supply arrangements for years to come.
The Outcome: Improved Water Storage Capacity & System Reliability
The new cold water tank provides significantly improved water storage capacity, ensuring a reliable and consistent water supply throughout the property.
By installing a larger water storage tank, constructing a purpose-built support platform and reconfiguring the existing pipework, Metro Plumb Walton-on-Thames delivered a solution tailored to the customer’s needs. The project demonstrates how a carefully planned water tank installation can improve system performance, increase storage capacity and provide a long-term solution for evolving property requirements.
