Water Tank Fittings

The fittings on your water tank are as important as the tank itself. Outlets, pipework, overflows, bulkheads, and connection points are all pressure-bearing contact components that, if specified incorrectly, undermine the performance of the whole system. Franklin Hodge water tank fittings are specified to the same engineering standard as the tanks themselves, selected to last for the operational life of the vessel.

What Materials Are Used on Franklin Hodge Tanks for Fittings, Connections, and Pipework? 

Franklin Hodge tanks feature fittings and connections made from materials such as galvanised steel, stainless steel, epoxy-coated steel, and UPVC. Each material is chosen for the specific application and environment the tank operates in. 

Galvanised steel fittings align with our hot-dip galvanised tank bodies and offer long-term durability on standard inland installations. Stainless steel is specified where higher corrosion resistance is required at the fitting level, regardless of the tank body material. Epoxy-coated steel adds a further protective layer for more demanding environments, and UPVC is used for lightweight, corrosion-immune service connections such as drains, overflows, and select pipework runs.

Types of Water Tank Fittings Franklin Hodge Supplies 

Every water storage tank we manufacture includes the full suite of fittings necessary for operation, including: 

• Water tank outlet fittings sized and positioned to match your system design 

• Water tank pipe fittings for inlet, outlet, and service connections 

• Water tank bulkhead fittings where pipework passes through the tank wall 

• Water tank overflow fittings to manage tank-level safety and regulatory compliance 

• Inlet ball float valves, level switches, drain valves, and contents gauges as part of the wider control set 

Specifications are matched to the application, whether that’s a fire protection tank, a WRAS-approved drinking water tank, or a waste and effluent storage vessel. 

Why Fitting Material Specification Matters 

The wrong material in the wrong place is one of the most common causes of premature tank failure. A plastic fitting on a high-pressure industrial line will fail. A standard steel fitting in a corrosive environment will corrode long before the tank body does. A non-potable-grade fitting on a drinking water tank will fail compliance. 

The point is simple: the tank is only as good as the fittings on it. Franklin Hodge has over 50 years of experience specifying both, and we don’t cut corners on either.

Spare Parts and Replacement Fittings 

If you have an existing Franklin Hodge tank and need replacement fittings, we stock and supply a wide range through our spare parts service. Our team can identify the correct specification from your original tank records and get the right part to you without guesswork, so you’re not left sourcing generic alternatives that won’t match.

Frequently Asked Questions 

What materials are used for Franklin Hodge water tank fittings?  

We specify fittings in galvanised steel, stainless steel, epoxy-coated steel, and UPVC depending on the application and operating environment. 

Are stainless steel fittings available even on galvanised steel tanks?  

Yes, we can specify stainless steel fittings on any tank where higher corrosion resistance is needed at the connection points. 

Does Franklin Hodge supply replacement water tank fittings?  

Yes, we stock and supply replacement fittings through our spare parts service for existing Franklin Hodge tank installations. 

Are Franklin Hodge fittings suitable for drinking water tanks?  

Yes, we specify potable-grade fittings across our WRAS-approved Liquistore® range to meet UK drinking water regulations. 

Can fittings be specified to suit specific site conditions?  

Yes, fitting materials are selected to match the tank application, operating environment, and any pressure or regulatory requirements.
