Overview of the Problem – Two Plumbing Issues in a Near-New Townhouse

At a townhouse on Clydebank Road in Edithvale VIC 3196, our team at Your Choice Plumbers was called out after the owner reported two frustrating plumbing problems in a home that was only around six months old.

The first issue was a bathroom basin that had become slow to drain. The second was an upstairs toilet cistern that had stopped filling properly altogether.

This is exactly the type of situation where homeowners start asking, “why is my basin draining slowly in a new house?” or “why has my toilet stopped filling if the home is nearly brand new?” As an experienced plumber Edithvale, we often explain that even in newer homes, plumbing fixtures still need maintenance — especially where modern water-saving or rainwater-fed systems are involved.

Why New Homes Can Still Have Plumbing Problems

Many people assume that if a home is recently built, the plumbing should operate perfectly without issue.

In reality, newer homes can still develop maintenance problems from:

  • everyday hair and soap build-up
  • debris collecting in waste fittings
  • rainwater sediment affecting toilet fill valves
  • modern system components needing periodic cleaning

So although this was a near-new townhouse, both issues still needed proper diagnosis and servicing rather than guesswork.

Diagnosing the Slow Bathroom Basin

We began by investigating the bathroom basin.

Once we inspected the waste assembly, we found a significant build-up of:

  • hair
  • soap residue
  • organic debris

The obstruction was concentrated both:

  • within the P-trap
  • around the pop-up basin plug and washer assembly

That meant the slow drainage was being restricted right at the point of discharge before the water even had a chance to move freely down the line.

This is something we often see on blocked drains Melbourne jobs, because what looks like a deeper drain issue is often caused by local fixture build-up that has never been properly removed.

Diagnosing the Toilet Cistern That Would Not Fill

We then moved to the upstairs toilet to inspect the fill problem.

A key detail with many modern townhouses in Edithvale is that they use harvested rainwater for toilet flushing as part of the home’s environmental setup.

That immediately made the inlet valve strainer a likely suspect.

Once we opened the cistern and inspected the inlet valve, we found the strainer was heavily blocked with:

  • fine sediment
  • dirt
  • rainwater tank particles

That blockage was preventing water from entering the cistern properly, which is why the toilet had stopped refilling.

This is the kind of issue we often explain on leaking toilet and toilet servicing jobs, because the toilet itself may appear faulty when the real issue is actually restriction at the inlet valve.

Basin Drain Clearing and Waste Service

To restore the basin properly, we removed the P-trap and thoroughly cleaned and sanitised all affected components.

We:

  • removed the built-up debris from the trap
  • cleared the pop-up plug and washer assembly
  • reassembled the waste correctly

To make sure the waste line beyond the trap was also clear, we used a pneumatic plunger to pressure-clear any remaining debris further down the basin waste pipe.

That left the whole basin waste path running freely again rather than only cleaning the visible trap.

Toilet Inlet Valve Strainer Cleaning

For the toilet, we removed the cistern cover and extracted the inlet valve strainer.

We then:

  • cleaned the sediment out thoroughly
  • reassembled the inlet valve
  • tested the fill behaviour
  • confirmed the cistern was refilling correctly and quietly again

This was a straightforward but important example of how rainwater-fed toilet systems can require occasional maintenance to keep the inlet components operating properly.

Final Testing and Outcome

Once both fixtures had been serviced, we carried out full testing on each one.

We confirmed:

  • the basin was draining properly again
  • there were no further restrictions in the waste path
  • the toilet cistern was filling efficiently
  • the fill rate and water level were returning to normal operation

The result was that both fixtures were restored to proper everyday use without needing any major replacement work.

Why This Job Matters in a Near-New Home

This case is a good reminder that even a six-month-old townhouse can still encounter practical plumbing issues.

In this home:

  • the basin problem was caused by normal bathroom debris build-up
  • the toilet problem was linked to sediment entering through the rainwater flushing system

Neither issue meant the plumbing was poorly installed. They were simply maintenance-related problems that needed the right diagnosis and servicing.

Compliance with Plumbing System Design and Maintenance Principles

This case related to the maintenance and servicing of internal sanitary fixtures and associated plumbing components, including basin waste fittings and cistern inlet valve operation.

In practical terms, this means the plumbing system was not failing structurally — it simply needed proper servicing to restore the intended performance of the fixtures. In homes with rainwater-fed toilet systems, maintenance of inlet strainers can be especially important to keep the system operating as designed.

All work carried out by Your Choice Plumbers is completed using the correct plumbing service methods so fixtures are restored properly and homeowners understand what maintenance may be needed moving forward.
