Confirm water readiness
Check whether the main supply, local valves and applicable fixtures can be operated within the confirmed scope.

What this means
Know what one visit can reveal about water flow without treating a running tap as proof of the whole plumbing system.
A normal-operation check records accessible flow and visible plumbing condition under the visit conditions. It does not confirm pressure throughout the home, concealed-pipe condition, installation compliance or future performance.
Practical sequence
Eight controls for responsible plumbing observations
The sequence keeps visible evidence, flow observations and specialist testing clearly separated.
02
Start with visible condition
Record accessible taps, outlets, fittings, exposed joints, hoses, cabinets and nearby finishes with location context.
03
Describe flow accurately
Record absent, weak, inconsistent or responsive flow as an observation unless a calibrated authorised pressure method is used.
04
State simultaneous use
Record which outlets were operated and whether tanks, pumps, heaters or management supply conditions could affect the response.
05
Separate drainage
Keep slow discharge, standing water and supply flow as distinct questions with their own method and evidence.
06
Respect concealed limits
A dry accessible surface does not confirm hidden joints, pipe sizing, pressure loss or installation compliance.
07
Preserve recurrence history
Keep dated photos, videos, notices, pump or tank history, repair invoices and notes about when the issue occurs.
08
Refer the open question
Repeated leakage, unexplained pressure loss, concealed dampness or system-design concerns need the appropriate specialist.
How it works
From a weak-flow concern to the right next check
Prepare
Make the supply, valves, utilities and agreed outlets available.
Observe
Record visible condition and authorised operation under the actual visit conditions.
Limit
State what access, equipment and concealed construction could not confirm.
Escalate
Use controlled testing or specialist plumbing investigation when the evidence gap requires it.
What this helps you decide
What helps clarify a plumbing concern
- Understand what the visit actually observed
- Keep supply, drainage and concealed questions separate
- Know when controlled testing or a plumbing specialist is required
Evidence and boundaries
What helps clarify a plumbing concern
- Exact room, outlet, fitting or accessible joint
- Supply, valve, pump, tank and utility status
- Outlets used and the observed response
- Visible staining, droplets, corrosion or repair marks
- Timing, recurrence and simultaneous-use pattern
- Earlier plumbing, pressure-test and repair records

Get Instant QuoteDoes DPM measure water pressure at every outlet?
Do not assume so. The selected package, available utilities, equipment and authorised method determine what can be observed or measured.
Does weak flow prove that a pipe is blocked?
No. Record the outlet, conditions and pattern, then use an appropriate specialist where diagnosis is required.
Can a dry wall rule out a concealed leak?
No. It records the accessible surface at that time. Concealed leakage may require history, controlled testing or opening-up work.
What if the water supply is off?
Affected checks remain limited or Not Checked and may require a later visit or specialist follow-up.
Is a general plumbing observation a certification?
No. It does not certify the complete plumbing installation or guarantee future performance.
