Pressure test report template

A pressure test report for pipework, filled in on a phone at the test. Record the section tested, the test medium (water, air or nitrogen) and the test your specification, code or water company requires: pressure, time and allowable drop, all entered by you. Scan the gauge label, record its calibration, check the safety precautions, then log the start and end readings with times and any readings in between. The form works out the drop and compares it with your allowable drop. A failed test and its retest are separate entries, so both stay on the record. For the plan of hold and witness points, use the inspection and test plan template.

For mechanical and plumbing contractors, pipefitters, site and project managers, clerks of works and engineers who test or witness pressure tests on heating, water, fire and process pipework.

Each test attempt with section, medium, required pressure, time and allowable drop from your specification
Gauge ID, range and calibration date, with a label scan
Start and end readings with times, readings in between, the calculated drop and a pass or fail against your figures
10 safety checks before pressurising, with extra controls for pneumatic tests
Leaks, repairs and retests, gauge photos, witnesses and signatures

What should a hydrostatic test report include?

A pressure test report is useful when anyone can see what was tested and to what: the section between named valves or points, the medium, the required pressure, time and allowable drop with the clause they come from, and a calibrated gauge. Start and end readings with times, and photos of the gauge, let the result be checked later. A failed test stays on the record next to its retest.

Last updated 27 October 2026. Facts checked by the SiteSurvey team on 27 October 2026 against HSE Guidance Note GS4, Safety requirements for pressure testing, Water Supply (Water Fittings) Regulations 1999, Schedule 2 paragraph 12 (legislation.gov.uk), Water Supply (Water Fittings) Regulations 1999, Schedule 2 paragraph 13 (legislation.gov.uk) and Provision and Use of Work Equipment Regulations 1998 (legislation.gov.uk).

How to record a pressure test

Have the specification clause or code requirement to hand before you start: the form does not supply test values.

Set up the record
Enter the site, the system, the specification or drawings the test is to, the testing contractor and who is testing.
Check the precautions
Work through the safety checks: written method, blanks and isolation, relief valve, rated hoses and fittings, hose restraints, gauge position, barriers, venting, raising pressure in stages and a safe way to release it.
Enter the required test
For each test, enter the section, the medium, and the required pressure, time and allowable drop from the specification. Scan the gauge label and record its calibration.
Log the readings
Record the start pressure and time, any readings in between, and the end pressure and time. Note and photograph any leak. The form calculates the drop and compares it with your figures.
Retest if it fails
If a test fails, record the cause and the repair, then add the retest as a new entry and link it to the first.
Close out and sign
Release the pressure safely, record how the system was left, and sign with the witness.

What makes a pressure test report useful

Each test: required pressure, time and allowable drop, then start and end readings with times

PT-01, LTHW flow and return, ground floor, V12 to V18: water, 6 bar for 60 minutes, no drop allowed (spec M-230 clause 4.2). Started 09:10 at 6.0 bar, 5.6 bar at 10:10, weep at a compression tee above the corridor ceiling. Fail. Olive replaced and joint remade; PT-02 retest held 6.0 bar from 13:30 to 14:30 with no leaks. Pass.

Fictional example. Record the actual evidence and approved arrangements for your job.

A common recording mistake

Writing only "tested OK" with no section, gauge or times, so nobody can show which pipework was tested, to what pressure, or that the failed joint was retested.

What happens next

Mark the tested sections on the drawings, release the pressure safely, and flush and disinfect water systems before they are first used.

Every question in the pressure test report template

A pressure test report for pipework, hydrostatic or pneumatic: the section tested, the test medium, the required pressure, time and allowable drop from the specification, the gauge and its calibration, safety precautions, start and end readings with times, the calculated drop and result, leaks, repairs and retests, gauge photos, witnesses and sign-off. 5 sections and 110 questions. Follow-up questions and guidance appear only when an answer calls for them, so the person on site never sees the ones that do not apply.

Make it your own: every question is editable

This is a starting point, not a fixed form. Once it is in your SiteSurvey account you can reword any question, add or remove questions, sections and answer options, and add your own logo, so it fits the way your team works and the jobs you do.

Safety before pressurising

CheckHSE guidance GS4 (Safety requirements for pressure testing) says pressure testing is a high-risk activity covered by PUWER 1998. It advises testing with water rather than a gas wherever possible to reduce the stored energy, and says leaks are harder to find in a pneumatic test, so it needs physical safeguarding as well as procedures.
Is any test on this record pneumatic (air or nitrogen)?*Yes or No
Extra controls for the pneumatic testNotes

Pressure test report FAQs

Is this a pressure test certificate?

It is a signed test record: the section tested, the required test, the gauge, the readings, the result and the witness signatures. It does not certify compliance with any standard. The test pressure, time and allowable drop come from your specification, the code that applies or the water company, and the form records them as you enter them.

What test pressure and time should I use?

The form does not say, because the right test depends on the system, the pipe material and the specification or code. In England and Wales, Schedule 2 paragraph 12 of the Water Supply (Water Fittings) Regulations 1999 sets the test pressure and tests for water systems, and paragraph 13 says every water system shall be tested, flushed and where necessary disinfected before it is first used. Heating, fire and process pipework are tested to their own specification.

Sources: Water Supply (Water Fittings) Regulations 1999, Schedule 2 paragraph 12 (legislation.gov.uk) and Water Supply (Water Fittings) Regulations 1999, Schedule 2 paragraph 13 (legislation.gov.uk).

Should I pressure test with water or air?

HSE guidance GS4 advises pressurising with water rather than a gas wherever possible, to reduce the stored energy in the system under test. It also says leaks are harder to find in a pneumatic test, so physical safeguarding is needed as well as procedures. If a test on the record is pneumatic, the form asks why water was not used and what extra controls were in place.

Source: HSE Guidance Note GS4, Safety requirements for pressure testing.

What safety precautions does HSE give for pressure testing?

HSE guidance GS4 says pressure testing is covered by the Provision and Use of Work Equipment Regulations 1998 and needs a written safe system of work. It describes a relief valve to prevent over-pressure, gauges and control valves away from the test area, hoses rated for the test and restrained, venting liquid systems before pressurising, raising the pressure in stages, barriers and warning notices, and a safe way to release the pressure. The form has a check for each.

Sources: HSE Guidance Note GS4, Safety requirements for pressure testing and Provision and Use of Work Equipment Regulations 1998 (legislation.gov.uk).

How does the form decide pass or fail?

It compares your readings with the figures you entered: the start pressure must reach the required test pressure, the time at pressure must reach the required time, the drop (start minus end) must not exceed the allowable drop, and there must be no visible leak. The tester also records the result; if the two differ, the form asks why. Water main and other tests that measure leakage by volume need the figure from your specification instead.

Can I record a water main pressure test with it?

Yes, as a record: enter the main and section, the test the water company or specification requires, the gauge, and the readings with times. The form does not hold any water company's test procedure or leakage formula, so attach the procedure or note its clause, and record any make-up water in the notes on the readings.
