Cold Water Storage Tank Installation

What cold water storage tank installation covers

A loft tank replacement or new installation is more than swapping a container. The work focuses on safe, reliable operation and tidy, serviceable pipework.

• Isolating and draining the existing tank and supplies (where applicable)
• Removing and disposing of the old tank (replacement jobs)
• Supplying and fitting a correctly sized cold water storage tank
• Installing and setting the float valve for accurate refill levels
• Checking and renewing associated valves and fittings where needed
• Connecting and securing inlet, outlet and warning/overflow pipework
• Ensuring the tank is properly supported and level
• Leak testing, functional checks, and recommissioning the system

When this service is most useful

This service is a good fit if your current loft tank is cracked, bowed, contaminated, or regularly overflows. It is also common when you are upgrading pipework, addressing low flow issues from a failing float valve, or preparing a property for new occupants. Landlords often choose replacement to reduce the risk of loft leaks and call-outs.

How the installation is carried out

You can expect a planned, step-by-step approach. The water supply is isolated, the system is drained as required, and access and working space in the loft are checked for safe installation. The new tank is positioned on suitable support, connected with secure fittings, then filled and tested to confirm correct shut-off, stable water level, and no leaks.

After the installation

Once the tank is running correctly, you will be shown the main isolation point and what to watch for. If the installation highlights related issues, such as deteriorated pipework, poor support, or unsuitable overflow arrangements, you will be advised on practical next steps. This helps keep the system reliable and reduces the likelihood of future water damage in the loft.
