High-Rise Firefighting Water
Permanently charged rising mains that put water on every floor the instant firefighters open a landing valve — designed, installed, pressure-balanced, and tested for taller buildings.
Always Charged. Always Ready.
In taller buildings, charging a dry main from street level takes too long. A wet riser is already full of water — with tanks, pumps, and pressure control engineered so crews get usable flow at height without delay.

Choose the Right Main
Both give firefighters floor-level water. The difference is when the pipe is charged — and that choice is driven by building height, fire strategy, and how quickly crews need usable pressure.
Permanently filled with water from tanks and pumps. Landing valves deliver flow immediately — typically specified for taller buildings where charging from the street would take too long.
Normally empty. The fire service connects to a ground-level inlet and charges the pipe so they can take water from landing valves without running hose up the stair.
When a wet riser is usually required
UK fire strategy commonly specifies a wet rising main where the highest floor is around 50 metres above fire-service access level — because pumping up from the street is no longer practical. We confirm the right approach against your fire strategy, building regulations route, and insurer requirements.

What We Deliver
From a new high-rise main to pump-room upgrades and statutory testing, we deliver practical wet riser solutions that stay serviceable under inspection and emergency use.
Complete wet rising mains for new builds and major refurbishments — tanks, pumps, vertical pipework, landing valves, PRVs, and identification aligned with the fire strategy.
Duty and standby pumping, tank capacity, pressure reducing valves, and gauges specified so lower floors are safe and upper floors still deliver usable firefighting flow.
Visual inspections, flow and pressure tests, leak diagnosis, seized valves, and plant faults — with certificates, defect reports, and prioritised remediations.
How a Wet Riser Works
A wet rising main is a living system — not a static pipe. Water is stored, pumped, and pressure-managed so every landing valve can deliver firefighting flow the moment it is opened.
Dedicated tanks hold the firefighting water supply the main depends on.
Duty and standby pumps maintain pressure so upper floors still get usable flow.
PRVs and gauges keep lower landings safe while high floors stay effective.
Crews open a landing valve and take water immediately — no street charge delay.
Plant & Landings
A reliable wet riser is more than a red cabinet. We look after the plant that keeps the main charged and the landing valves firefighters will actually use.
Pump rooms, tanks, and controls sit behind the scenes. Landing valves sit on the firefighting stair. Both have to work together — with records that prove the system is ready when inspectors, insurers, or the brigade ask.

System Anatomy
If tanks, pumps, PRVs, or landing valves are neglected, the main can look complete and still fail under load. We specify and maintain the full assembly.
Dedicated capacity so the main has a firefighting supply independent of everyday building use.
Plant that maintains pressure at height, with redundancy so a single failure does not empty the strategy.
Fixed pipework kept full of water, rising through cores to serve landing outlets on every required floor.
Floor outlets for firefighters to connect hoses immediately — clearly signed, accessible, and operable.
Control devices that keep lower-floor pressures safe while upper floors still deliver usable flow.
Monitoring, test points, and identification so crews and inspectors can use and prove the system.
End-to-End Service
SAFECORE manages the full wet riser lifecycle so plant stays healthy, valves operate freely, and test records are ready when inspectors or the fire service ask.
We assess height, cores, water supply, plant space, and existing mains — then specify tanks, pumps, pipe sizes, and PRV layouts to suit the fire strategy.
Pipework, tanks, pumps, landing valves, PRVs, cabinets, and signage installed by experienced engineers with tidy finishes in plant rooms and public cores.
Pressure proving, flow tests, pump performance checks, valve operation, and handover documentation so the main is proven before occupation.
Location schedules, plant operating notes, and guidance for building teams on keeping landings, tanks, and pump rooms accessible.
Scheduled inspections, pump running, valve lubrication, leak checks, and defect remediation so the charged main stays serviceable year after year.
Coordinate wet risers with fire alarms, emergency lighting, AOVs, and dry risers so life-safety systems work as one strategy.
Tested. Documented. Ready.
A wet riser must hold pressure, deliver flow, and operate at every landing — not just look correct on a drawing. Our testing regime checks integrity, plant, and access.

How It Works
No vague packages — just a structured process that specifies the right plant, installs it cleanly, and keeps testing under control.
Free visit to assess height, cores, tanks, and plant space.
Clear scope for install, plant, test, or remedial works.
Professional installation or repair with planned access.
Flow, pressure, and pump checks with records.
Planned inspections and priority call-out support.
Keep It Charged
Because the main is always full of water, leaks, seized valves, and plant faults show up in daily building life. Planned checks catch problems before an emergency or a failed inspection.
Building owners and responsible persons typically remain accountable for keeping firefighting mains usable. We provide the technical programme — inspections, pump running, testing, and remediations — with documentation for insurers, freeholders, and enforcement bodies.
Landing cabinets clear, gauges readable, obvious leaks reported, plant room accessible.
Valve movement, pump running, controls, and early defect logging before they become failures.
Flow and pressure proving, plant performance, written certificates, and a prioritised remedial plan.
Where We Work
From residential towers to hospitals and mixed-use schemes, we design and maintain wet rising mains around real plant rooms, stair cores, and fire service approach.
High-rise apartments and mixed-use blocks with charged mains in firefighting stairs.
Tall workplaces needing reliable plant, pressure control, and documented testing.
Guest buildings where instant water at height and discreet plant rooms matter.
Sensitive sites needing dependable mains and carefully planned out-of-hours works.
Taller teaching blocks and multi-building estates with managed service schedules.
Schemes combining residential, retail, and offices under one firefighting strategy.
Charged mains leak, PRVs drift, and pumps sit idle until they are needed. Planned inspections catch problems early and leave you with records that prove the system has been maintained.

Common Questions
Straight answers for landlords, managing agents, developers, and facilities managers responsible for taller buildings.
A wet rising main is a vertical firefighting pipe that is permanently charged with water from tanks and pumps. Firefighters open a landing valve on the floor they need and take water immediately, without first charging the main from a street hydrant.
Wet risers are typically specified for taller buildings — commonly where the highest floor is around 50 metres above fire-service access level — because charging a dry main from the street takes too long. The fire strategy and building regulations route for your project decide the exact requirement.
Usually dedicated water storage, duty and standby pumps, pressure reducing valves on lower floors, landing valves, gauges, and identification. We survey the building and specify plant that matches height, occupancy, and available plant-room space.
They should be inspected and tested on a planned programme aligned with BS 9990 and your fire risk assessment — commonly including regular visual checks, pump running, and periodic flow and pressure testing. We set a schedule that matches your building and risk profile.
Usually the building owner, freeholder, or responsible person under fire safety law. Managing agents often coordinate testing and repairs. We provide the technical works and documentation you need to demonstrate due diligence.
Yes. We diagnose leaks, replace gaskets and valves, attend to PRVs, investigate pump and control faults, and re-test so you can return the main to a serviceable condition with updated certificates.
Yes. We install, test, and maintain wet risers across Sussex and further afield across the UK. Contact us with your postcode for availability and lead times.
