Drains That Keep Blocking

One slow sink or shower can indicate a local obstruction. When several drains become slow, toilets start gurgling or the same blockage continually returns, the problem may be further within the drainage system.

Avoid repeatedly using chemical drain cleaners when the cause is unknown. Instead, notice whether multiple fixtures are affected or whether using one fixture causes water levels to change somewhere else.

Recurring blockages can involve accumulated waste, tree roots, damaged pipework or another restriction within the drainage system.

NLK Plumbing can clear the immediate blockage and use CCTV drain cameras where further investigation is required.

If wastewater begins backing up through a toilet, shower or floor drain, stop using the affected plumbing. Continuing to send water into a restricted system can make the situation worse.

Hidden Water Leaks

Not every water leak appears directly beneath the damaged pipe. Water can move through walls, ceilings, cabinetry and flooring before becoming visible.

Watch for damp patches, water stains, musty smells, unexplained moisture, pressure changes or increasing water usage without an obvious reason.

Start by checking accessible plumbing underneath sinks, around toilets and near appliances. If you cannot identify the source, further investigation may be necessary.

Avoid simply drying, painting or repairing the visible water damage without determining where the moisture originated.

NLK Plumbing can investigate suspected concealed leaks and use professional leak detection equipment where required.

Finding a hidden leak early can help reduce continued water loss and prevent moisture spreading further into cabinetry, flooring, walls or other areas of your home.

Older or Altered Pipework

Renovations do not necessarily mean every section of a home's plumbing has been replaced. A renovated bathroom or kitchen may still connect to pipework installed much earlier.

Warning signs can include recurring leaks, discoloured water, unusual pipe noises, pressure changes or repeated problems affecting the same section of plumbing.

One isolated leak does not automatically mean extensive replacement is required. However, repeated failures deserve further investigation.

A plumber can assess accessible pipework and determine whether the problem is limited to one fitting or section, or whether deterioration elsewhere needs attention.

NLK Plumbing's experience across different generations of Melbourne homes allows us to assess the condition of the plumbing and explain the available repair options.

Replacement should only be recommended when the condition of the plumbing justifies it.

Low or Changing Water Pressure

Water pressure problems can affect showers, taps and appliances, but where the change occurs provides useful information.

If only one tap or shower has poor pressure, the problem may be limited to that fixture. If several outlets are affected or pressure changes suddenly throughout the home, the cause may require further investigation.

Look for other changes occurring at the same time, including damp areas, unexplained water sounds or increased water usage.

Do not assume reduced pressure is simply normal because your home is older.

NLK Plumbing can assess pressure problems and determine whether the cause is localised or connected to another plumbing fault.

Understanding why the pressure has changed allows the correct problem to be addressed rather than simply replacing individual taps, showerheads or fixtures.
