Water Tank Connections

A water storage tank doesn’t sit in isolation. It feeds pumps, booster sets, filtration, sprinkler systems, and wider site pipework, and every one of those interfaces is a connection point that has to be specified, sized, and built into the tank itself. Get that wrong at the start, and you’re either retrofitting on an otherwise compliant tank or compromising the system downstream.

Can Franklin Hodge Tanks Be Supplied with Connections for Other Equipment?

Yes, Franklin Hodge tanks can be supplied with a range of flange and spool connections for additional equipment installation. These are designed and built into the tank at manufacture, so connection positions, diameters, and mating specifications are set correctly the first time rather than worked around on site. 

Flange connections are the standard interface for joining the tank to bolted pipework, valves, or downstream equipment. Spool connections are short pipe sections with flanges at both ends, used to link equipment to the tank with a defined, serviceable joint that can be removed for maintenance without dismantling the surrounding system.

What You Actually Connect to a Franklin Hodge Tank 

In most industrial water storage installations, the connections coming off the tank fall into a few categories: 

• Pump and booster set connections for pressurising water into the wider supply, whether that’s a sprinkler installation, a potable water network, or a process loop 

• Filtration and treatment connections where water passes through conditioning equipment before use or before return to storage 

• Inlet and outlet pipework manifolds distributing flow across multiple tanks or multiple service points 

• Instrumentation and control connections for pressure sensors, flow meters, and level monitoring equipment 

• Bypass and isolation connections allowing maintenance on downstream systems without taking the tank out of service 

Each of those requires the right flange specification, a compatible bolt pattern, gasket compatibility with the stored liquid, and physical positioning on the tank wall that works with the wider pipework layout.

Why Specification at Manufacture Matters 

The alternative is retrofit. Retrofit means cutting into a tank that was otherwise correctly built, creating a new aperture, fitting a new flange, and hoping the seal holds. For a fire protection tank that needs to maintain LPCB certification, that’s a compliance problem. For a WRAS-approved drinking water tank, it’s a potable water compliance problem. For a concrete-lined tank or waste and effluent storage tank, cutting into the wall after the fact compromises the lining system. 

Specifying connections before the tank is built avoids all of this. The connection is engineered into the panel from the start, correctly sealed, correctly certified, and correctly positioned.

Retrofit Connections on Existing Tanks 

If you have an existing Franklin Hodge tank that needs additional connections for new equipment, our tank refurbishment services can assess the tank and add connection points as part of a controlled refurbishment scope. That way the tank body, lining, and certification pathway are handled together rather than patched in isolation.

Talk to Franklin Hodge Before You Finalise Your Tank Specifications 

If you’re putting together the specification for a tank and know it will need to connect with pumps, filtration, sprinkler pipework, or other site equipment, raise the connection requirements early. Our engineering team will work through the flange and spool specifications with you before anything is manufactured, which saves time, cost, and headaches further down the line. Request a quote with your full scope and we’ll be in touch.

Frequently Asked Questions 

What types of connections does Franklin Hodge supply on its tanks?  

We supply flange and spool connections designed into the tank at the manufacturing stage to suit the equipment being installed. 

Can connections be added to an existing tank?  

Yes, additional connections can be added as part of our tank refurbishment services, with the tank body and lining handled together. 

What equipment typically connects to a Franklin Hodge tank?  

Pumps, booster sets, filtration, pipework manifolds, instrumentation, and bypass lines are among the most common connections. 

Are connections matched to the stored liquid?  

Yes, flange material and gasket specification are matched to the stored liquid to ensure compatibility and long-term seal integrity. 

Should connection requirements be raised before manufacture?  

Yes, raising connection requirements at the specification stage is the best way to avoid retrofit costs and compliance complications later.
