A Plumber's Guide for Property Managers: Is It Even a Plumber, and What the Report Should Say

Close to a third of the work we do comes in on a work order, so this is written from your side of it rather than ours.

Property managers tell us the hardest call is not urgency. It is deciding whether a plumber is even the right trade, from a tenant’s description, before spending anyone’s money finding out. So that is where this starts.

Is this a plumber’s job?

A rough guide to the reports we get most, and where they usually land.

What the tenant reports	Usually	Who
No hot water anywhere	Element, thermostat or power supply	Electrician first
Hot water lukewarm at every tap	Cylinder not heating	Electrician
Hot water runs out fast, or fluctuates	Often normal for the system, or sizing	Plumber to confirm
Water on the bathroom floor, tiled shower	Could be either. See below	Plumber first
Wet carpet next to a bathroom	Often waterproofing, not pipework	Plumber first, then tiler
Ceiling stain that only appears after rain	Roof, flashing or spouting	Roofer
Ceiling stain with no rain	Pipe or waste above	Plumber
Dishwasher or washing machine leaking	Connection, or the appliance itself	Plumber to split it
Appliance not draining	Hose, or the machine	Plumber
Waste disposal humming or dead	Usually the unit’s motor or switch	Plumber to confirm, then replace
Water in the garage when it rains	Drainage, not a leak	Plumber for drainage
Gully or manhole overflowing	Blocked drain, possibly council’s	Watercare first
Smell of gas	Gas fault until proven otherwise	Gasfitter, urgently
Toilet rocking or leaking at the base	Fixings, pan connector or seal	Plumber

Two things worth saying about this table. Several of these are ours to diagnose even when they are not ours to fix, because eliminating the plumbing is usually the cheapest test available. And where it is not us, we will say so in the report and name the trade, rather than leaving you with “not plumbing”.

The one that comes up most: tiled showers and waterproofing

This is the most common boundary question we get from property managers, and the honest answer is that you cannot tell from the outside, and neither can we until we have tested.

A tiled shower leaking into the room next door, or into the ceiling below, has two completely different families of cause:

Plumbing. The mixer behind the wall, the waste connection, the tray, the trap. Ours.
Waterproofing. The membrane under the tiles, failed grout, perished silicone at the tray junction. A tiler or waterproofing specialist.

We test the plumbing first because it is faster, cheaper, and less destructive to check. At a property on Target Road we tested the visible supply lines and function-tested the drainage. Everything held, with no leakage anywhere. The damp pattern was consistent with a waterproofing membrane failure in the bathroom floor rather than a pipe defect, so our report said exactly that and recommended a builder or tiler check the waterproofing. No plumbing repair was required.

In Te Atatū South we water-tested a fully tiled shower for a ceiling leak below. It did not leak immediately, but the pattern indicated water slowly penetrating through the tiled area. We reported that the membrane may have failed, and that the exact failure point could not be confirmed without opening up or a waterproofing specialist.

Sometimes it does land on us. In Takanini a tiled bathroom was flooding out past the doorway, and when we lifted the shower tray it had been installed incorrectly and was letting water out underneath every time the shower ran. At Don Buck Road a leaking shower waste turned out to be a glued joint that had never been properly sealed.

What this means for a work order: budget for the investigation as a step of its own. A tiled shower leak is rarely diagnosed and repaired on the same visit, and anyone who says otherwise before testing is guessing.

When it is clearly not our trade

We diagnose past our own boundary, because a report that stops at “not plumbing” is no use to you.

Hot water. At Waratah Street a tenant reported the shower not running hot, shortly after we had replaced a basin mixer there, so the obvious suspicion was our own work. We ran both and found the maximum was about 35 degrees at the basin as well as the shower, which cleared both fittings and pointed at the cylinder not heating. Element and thermostat are electrical, so the recommendation was a registered electrician to test and replace, and an offer to re-check the fixtures afterwards. That lets you raise the right order the same day instead of sending a second plumber.

Appliances. At Central Park Drive a dishwasher was leaking. We found the connection had been fitted incorrectly and re-fitted it properly, then ran a test cycle. Water still came out, this time from inside the unit. Our report separated the two clearly: the plumbing connections are now correct and watertight, the remaining leak is an internal appliance fault, and the route is a warranty claim with the supplier.

Electrical work around gas and cylinders. We are not a licensed electrical contractor and we say so on the invoice. On a hard-wired gas cooktop at Spencer Road we reconnected the existing wiring but noted that a licensed electrician must inspect and confirm it is safe and compliant.

Making good. When we open a wall or ceiling to find a leak, patching, stopping and painting is a plasterer or builder and is excluded from our price. We put that in the quote rather than letting it arrive as a surprise.

Does this actually need an after-hours callout?

Every job is urgent to the person reporting it, and they are not wrong to feel that way. But “urgent” in our pricing means one specific thing: somebody comes out tonight, or on the weekend, at an after-hours rate. The real question you are answering is not how serious it is. It is whether it can wait until the next working day.

The line that decides most of it is whether the water is inside the building.

Water inside the house, and it cannot be stopped. That is tonight. It is doing damage every hour, and the cost of the callout is small against a ceiling or a floor.

Water outside the house. Next day is almost always fine, even when it looks dramatic. A leak in the berm, a wet driveway, water coming up in the lawn, a dripping outside tap. It is going into the ground rather than into the building, and nothing about waiting until morning makes the repair harder. What it costs is water, and one night of it is not worth an after-hours rate.

If a tenant can shut the water off at the meter box, an inside leak often becomes a next-day job too. That is the single most useful thing to teach them, and the water meter box guide is written so they can follow it. A tenant in Totara Vale shut the mains off themselves when a pipe burst on a Sunday, which is exactly the right call.

The exceptions that are urgent wherever they are:

Any smell of gas. Always, no judgement call.
Sewage surfacing, inside or out. It is a health issue rather than a water-damage one. Ring Watercare first, because it may be theirs. We took a Saturday callout in Birkdale for a gully actively overflowing with toilet paper.
No water at all to the property. The household cannot function.
The only toilet in the house out of service. Genuinely urgent rather than an inconvenience, and we attended exactly that on a Saturday in Forrest Hill.
Water anywhere near a switchboard, which stops being a plumbing problem.

Everything else is a normal booking. A contained leak, a cylinder weeping without flooding, intermittent hot water, a drain that has blocked before. Dripping taps, slow drains and running cisterns are real money on a water bill but they are not emergencies, and they bundle well into one visit across a portfolio.

When you ring, the most useful thing you can tell us is whether water is actively running and whether it is inside. That is what decides tonight against tomorrow, and it lets us give you the honest answer rather than defaulting to an after-hours rate.

Insurance: the one you deal with most

Most water damage at a rental ends up as a claim, so this is where our paperwork earns its keep.

What is usually covered. A sudden failure and the damage it causes, which is the flooring, ceilings, carpet, contents and the drying. What usually is not: finding and repairing the pipe itself, and anything the insurer decides was gradual.

Sudden against gradual is the whole argument. A hose that lets go is sudden. A joint that has been weeping into a ceiling for months is gradual, and gradual is excluded under most policies. This is why a leak that a tenant mentioned three months ago is a much harder claim than one reported the day it started, and why prompt reporting is worth pushing with tenants.

What our report gives you, written knowing an assessor reads it: what failed, exactly where, when it was found, whether it was sudden or long-running, and what we did to make it safe. Where we can date the failure, we date it.

Is it worth claiming at all? Not always, and it is worth deciding rather than claiming by reflex. A single fitting plus a bit of lining and a repaint may not be far off the excess, and a claim sits on the record at renewal. Once carpet has to be lifted and dried, framing dried out, ceilings rebuilt and rooms repainted, the total goes well past what people expect and that is exactly what the cover is for.

Practical sequence that avoids arguments: stop the water, photograph everything before anybody cleans up, keep the failed part, then get the report. We attended an emergency in Orewa where a 15mm fitting had burst with age; we repaired it and recommended the property manager arrange drying of the carpet to prevent odour and mould, which is the kind of line an assessor wants to see in writing.

Tenant-caused, or wear and tear?

You need this called accurately and in writing, so we write what we actually found in the pipe rather than a general description.

At Milan Drive we cleared a basin blockage in May. It blocked again within a few months, and when we pulled the waste and trap apart there was a very large accumulation of hair and debris built up all over again. That went out as a tenant charge, with the report saying the blockage was caused by hair and foreign material going down the basin rather than any fault with the plumbing, and setting out what needed to stop.

At Saltmarsh Road a kitchen waste was packed with egg shells and fruit peel from the disposal, with the same recommendation to advise the tenant.

In Mairangi Bay a report of leaks in the garage and laundry turned out to be one genuinely failed laundry mixer, which we replaced, plus a cork floor the tenant had been washing down with water. The water marks were not a plumbing fault at all.

None of those reports say “the tenant’s fault”. They say what was in the pipe, or what the floor is made of. That is what holds up in a conversation with a tenant.

Watercare: two ways to get money back

Leak allowance. A hidden leak that has inflated a water bill can often be partly credited back once it has been found and repaired, with evidence. We note it on the invoice when a job qualifies. On a long-running underground leak the water charge can exceed the repair.

Council-side drainage, which fewer people know about. On an after hours callout in Birkdale a gully trap was overflowing. We jetted the line, and clearing it alone did not resolve the fault, so we ran a camera. The CCTV put the blockage near the council connection, verified against Watercare’s GIS records. That made it Watercare’s, and the cost of the work could be claimed back by the owner using the service request number we obtained.

That claim only existed because somebody looked. Clear a drain without a camera and there is no evidence and no claim.

What to put on the work order

The difference between one visit and three is usually information.

What the tenant actually said, in their words.
When it happens. Only when the shower runs, only after rain, constantly, worse overnight. The most useful line on any work order.
Access. Keys, dog, lockbox, whether the tenant is home.
Tenant’s mobile, so we can ring from the gate.
History. A repeat blockage is a different job and changes whether we bring a camera.
Approval limit. What we can just do, and where we stop and ring you.

Common questions

Do you charge for a visit where nothing was wrong?

Yes, the attendance is charged, and we will tell you plainly that we found no fault rather than inventing work. Those visits often save money over a year because a clear “this is not a fault, and here is why” ends a recurring maintenance request permanently. Where something takes two minutes and is not really a job, we do not charge for it.

Can you deal with the tenant directly?

Yes, and it usually speeds things up. Send the tenant’s mobile with the work order and we will arrange access and keep you copied. Anything that changes scope or cost comes back to you first. We report to you rather than to the tenant, but we do explain what we found to them, which stops the same request being raised again next month.

Will you quote before doing the work?

For anything beyond a straightforward repair, yes. Where the fault is concealed we quote the investigation first, because nobody can price a repair for something not yet located, then quote the repair once it is exposed. Tell us your standing approval limit and we will work to it and only ring you above it.

Who is responsible for the drains at a rental?

The private drain from the house to the public connection is the owner’s, the public main is Watercare’s. Tenant behaviour can block an owner’s pipe, which is where an accurate report matters. If the blockage is at or past the council connection it is Watercare’s to fix and potentially to pay for.

Can you work off our system’s work orders?

Yes. We take them by email and through the property management systems the agencies we work with use, and the completed report and photos come back the same way. If your workflow needs something specific in the report, tell us once and we will build it in.
