Dry and Wet Riser Testing
Missing test records, damaged inlet boxes, leaking valves or an upcoming inspection can prompt work. Describe when the issue started and any change in use, operation or layout. A clear history helps distinguish a new fault from an existing limitation or a planned improvement.
Discuss your requirementsDefined services, clearly scoped.
Overview
For an estate instruction, list affected sites separately. One recurring symptom can have different causes on different installations, so retain the local history and restrictions.
What the work can include
Identify inlets and landing valves; examine visible condition and signage; carry out the agreed system tests; record readings, leaks and inaccessible points. The agreed scope should state which areas or equipment are included, what is excluded and the form of the completion record.
Use asset or location references that can be matched to your existing records. This makes the findings useful for budget decisions, repeat work and subsequent inspections.
Important decisions
A dry riser and a permanently charged wet riser have different arrangements. Confirm the system type before specifying a test or isolating a supply.
Assessment and preparation
Provide riser drawings, previous test results, inlet locations and access to every relevant floor.
Name the site contact, technical approver and person who will receive the action list. Identify permit, shutdown and contractor coordination requirements before arranging attendance.
How the work proceeds
Agree water supply and discharge arrangements, protect occupied areas, carry out controlled testing and record the restored condition.
Where the work forms part of a wider programme, agree the order of sites and the route for escalating material findings. Keep partial completion visible rather than closing a whole site while actions remain open.
Cost, timing and disruption
Building height, number of risers, valve access, water arrangements and remedial defects affect the visit. The enquiry and available records establish what can be priced directly and what needs a site assessment first.
A coordinated programme can group suitable tasks, but access windows and operational dependencies still need to be checked for each building. Agree how additional findings will be reported and priced.
Applications across sectors
Sleeping accommodation raises different evacuation and access considerations from daytime offices. Education premises need work arranged around children and staff; warehouses need attention to storage and changes in layout. The actual use and fire arrangements govern the scope. Browse the full sector range and describe the actual building use when enquiring.
Frequently asked questions
Does a successful pressure test prove every part is satisfactory?
No. The report should also identify the visual checks, functional checks, restrictions and defects within the agreed scope.
What information should I send about dry and wet riser testing?
Provide riser drawings, previous test results, inlet locations and access to every relevant floor. Include the location and the decision you need to make, such as investigating a fault, planning a repair or setting up a programme.
What affects the price and programme?
Building height, number of risers, valve access, water arrangements and remedial defects affect the visit. Any further investigation or additional work should have a clear scope before it is authorised.
What should the completion information explain?
It should identify the equipment or areas covered, the work and checks performed, limitations and unresolved actions. Match the records to your site and asset references so the next inspection or maintenance visit can use them.
