Water tank access hatch

The access hatch on a water storage tank is a small detail with a big practical impact. It’s the difference between routine inspection of inlet controls being a quick task or a half-day operation. Specify it wrong, undersize it, or leave it out, and every subsequent maintenance visit becomes harder than it needs to be. Franklin Hodge tanks include a standard access hatch as part of the ball valve housing, sized and positioned for the way your team will actually use it.

Are Franklin Hodge Tanks Supplied with a Roof or Cover Access Hatch? 

Yes, our standard ball valve housing includes an access hatch for convenience. The hatch sits at the top of the tank within the ball valve housing structure, giving direct access to the inlet ball float valve and any associated controls without requiring full tank entry through the lower-level manway. For routine maintenance, valve inspection, or control adjustments, this is the access route you’ll use most often.

Where Your Water Tank Access Hatch Sits 

Industrial water tanks have access at multiple points, and each point exists for a different reason. The water tank access hatch on a Franklin Hodge tank is built into the ball valve housing at the top of the tank, where the inlet pipework, ball float valve, and level controls converge. 

That positioning is deliberate. The components inside the ball valve housing are the ones that need the most frequent attention over the life of the tank: inlet valves, float arms, and level switches. A hatch positioned exactly where those components live, rather than somewhere generic on the roof, removes friction from every routine task.

Sprinkler Tank Access Hatch Requirements 

For fire protection tanks supplying LPCB-certified sprinkler systems, accessible inlet controls aren’t a nice-to-have, they’re a compliance requirement. The certification standards assume maintenance teams can readily inspect, test, and verify the condition of the inlet ball valve and associated controls. A sprinkler tank access hatch built into the ball valve housing meets that requirement directly, so every routine compliance inspection becomes a straightforward walk-up task rather than a planning exercise.

How the Ball Valve Housing Access Hatch Works 

The ball valve housing on a Franklin Hodge tank is a sealed, weather-tight enclosure protecting the inlet controls from contamination, debris, and environmental exposure. The integrated access hatch allows that enclosure to be opened cleanly when access is needed and resealed afterwards, without compromising the integrity of the tank or the stored water. This setup supports ball float valve inspection, visual verification of inlet operation during compliance walk-rounds, and access for any level switch positioned at the top of the tank.

Hatch and Manway Together: Full Tank Access 

A Franklin Hodge water storage tank is supplied with access at two points: the ball valve housing access hatch at the top for inlet work, and a low-level access manway at the base for full internal entry. The two work together rather than duplicating each other. Top access serves high-frequency, low-disruption tasks. Low-level access serves the less frequent but more involved work like internal inspection, liner checks, and full refurbishment, including condition assessments carried out as part of our tank survey service.

Replacement Access Hatches and Seals 

Access hatch covers, seals, and weather-tight fittings will wear over the working life of the tank and may need periodic replacement. Replacement parts are available through our spare parts service, matched to the original tank specification so the seal integrity and certification status of the tank are preserved when components are renewed.

Frequently Asked Questions 

Are Franklin Hodge tanks supplied with an access hatch as standard? 

Yes, every tank we manufacture includes a standard access hatch built into the ball valve housing at the top of the tank. 

Where is the access hatch located on the tank? 

The access hatch sits on the ball valve housing at the top of the tank, giving direct access to the inlet controls. 

Is the access hatch the same as the low-level manway? 

No, the access hatch is for inlet control access at the top, while the low-level manway provides full internal entry at the base. 

Are sprinkler tank access hatches LPCB-compliant? 

Yes, our access hatch specification supports LPCB compliance requirements for fire sprinkler tank inlet inspections. 

Can replacement access hatch covers be supplied? 

Yes, replacement covers, seals, and fittings are available through our spare parts service for existing Franklin Hodge installations.
