Kitchen Plumbing

Kitchen Plumbing

Your kitchen is one of the hardest working areas in the home.

Between cooking, washing, cleaning, dishwashers, filtered water systems and daily sink use, the kitchen plumbing system is under constant demand.

When something goes wrong, it can disrupt the whole household quickly.

A blocked kitchen sink, leaking mixer tap, under-sink leak, dishwasher connection issue or drainage smell is not just inconvenient. If ignored, kitchen plumbing problems can lead to water damage, wasted water, damaged cabinetry and recurring blockages.

At RJT Plumbing & Gas Solutions, we provide practical kitchen plumbing repairs, replacements and installation support for homeowners who need the issue assessed properly and fixed correctly.

Whether it is a minor repair, a recurring problem or plumbing work as part of a kitchen renovation, our team can help identify the cause and recommend the most cost-effective solution.

Kitchen Plumbing Services We Provide

Kitchen plumbing covers more than just the sink.

We can assist with:

• leaking kitchen taps
• kitchen mixer tap replacement
• blocked kitchen sinks
• under-sink leaks
• sink waste repairs
• dishwasher plumbing
• dishwasher installation connections
• fridge water line installation
• water filter tap connections
• kitchen drainage issues
• pipework under the sink
• isolation valve replacement
• hot and cold water pipework
• kitchen renovation plumbing
• sink and mixer upgrades
• waste trap repairs
• odours from kitchen drains
• compliance checks for kitchen plumbing work

Some kitchen plumbing problems are obvious straight away. Others build slowly over time and only become noticeable once water starts leaking into cabinetry, drains begin smelling or the sink starts emptying slowly.

Getting the issue checked early can help prevent more expensive damage later.

Blocked Kitchen Sinks

A blocked kitchen sink is one of the most common kitchen plumbing issues.

Kitchen drains deal with food scraps, oils, grease, detergent, coffee grounds and general build-up every day.

Over time, these materials can restrict the pipework and cause the sink to drain slowly, smell unpleasant or back up completely.

Common signs of a blocked kitchen sink include:

• water draining slowly
• gurgling sounds from the drain
• unpleasant smells from the sink
• water backing up into the bowl
• repeated blockages
• pooling water under the sink
• waste traps filling or leaking

A blocked kitchen sink should be assessed properly, especially if it keeps coming back.

Recurring blockages can point to a deeper drainage issue rather than a simple surface-level restriction.

Leaking Kitchen Taps and Mixer Repairs

Kitchen taps and mixers are used constantly, so wear and tear is common.

A leaking tap might seem minor, but it can waste water, increase bills and cause damage around the sink area if water gets into the benchtop or cabinetry.

We can help with:

• dripping kitchen taps
• leaking mixer taps
• stiff or hard-to-use mixers
• loose tapware
• poor water flow
• tap replacement
• kitchen mixer upgrades
• water hammer or noisy tap issues
• faulty isolation valves

In some cases, repairing the existing tapware makes sense. In others, replacement provides better reliability, improved function and a cleaner result.

Under-Sink Leaks

Under-sink leaks can cause significant damage because they often go unnoticed until cabinetry starts swelling, smelling damp or showing visible water marks.

Common causes of under-sink leaks include:

• loose waste connections
• leaking traps
• worn seals
• faulty isolation valves
• leaking flexible hoses
• dishwasher connection issues
• poor pipework alignment
• damaged fittings

Even a small leak under the kitchen sink can damage cabinetry over time.

If you notice moisture, swelling, mould, damp smells or water pooling under the sink, it is worth getting the plumbing checked before the problem gets worse.

Dishwasher Plumbing and Connections

Dishwashers need correct water supply and waste connections to operate safely and reliably.

Poor dishwasher plumbing can lead to leaks, drainage issues, smells, poor performance or water backing up into the sink.

We can assist with:

• dishwasher water connections
• dishwasher waste connections
• dishwasher replacement plumbing
• leak repairs around dishwasher connections
• isolation valve installation
• blocked dishwasher drainage
• new dishwasher plumbing during kitchen upgrades

f a dishwasher is not draining properly, leaking nearby or causing sink drainage issues, the plumbing connections should be inspected.

Fridge Water Line Installation

Many modern fridges require a plumbed water connection for chilled water and ice makers.

Fridge water lines need to be installed properly to reduce the risk of leaks behind cabinetry or appliances.

We can help with:

• fridge water line installation
• fridge tap connections
• water supply points for new fridges
• isolation valves
• leak checks
• compliant pipework installation

Because fridge leaks can happen behind the appliance, they can be difficult to notice early.

A proper installation helps protect flooring, cabinetry and surrounding finishes.

Water Filter Tap Plumbing

Kitchen water filters and filtered water taps are becoming more common in modern homes.

These systems need suitable water connections, correct installation and reliable fittings to avoid leaks and maintain good performance.

We can assist with:

• water filter tap installation
• under-sink filter connections
• replacement filter tap plumbing
• leak repairs around filter systems
• isolation valve checks
• pipework adjustments for filter systems

A poorly connected water filter system can create leaks inside cabinetry, so proper installation matters.

Kitchen Drainage Smells

Bad smells from the kitchen sink are often caused by plumbing or drainage issues.

Common causes can include:

• food and grease build-up
• partially blocked drains
• waste trap issues
• poor pipework fall
• leaking waste connections
• dry or faulty traps
• dishwasher waste problems

If kitchen drain smells keep returning after cleaning, the issue may be deeper in the pipework.

RJT Plumbing & Gas Solutions can help identify the source of the smell and recommend the right plumbing solution.

Kitchen Renovation Plumbing

Kitchen renovations need properly planned plumbing before cabinetry, benchtops and appliances are installed.

Kitchen renovation plumbing may involve:

• relocating sink plumbing
• relocating hot and cold water points
• installing new mixer taps
• connecting dishwashers
• installing fridge water lines
• adding filtered water taps
• changing waste pipework
• installing isolation valves
• upgrading under-sink plumbing
• compliance checks

Getting the plumbing right during a kitchen renovation is critical.

Poor planning can lead to leaks, awkward appliance placement, poor drainage, restricted access under the sink or expensive changes later in the project.

RJT Plumbing & Gas Solutions can work with homeowners, builders and renovators to ensure kitchen plumbing is installed correctly and suited to the layout.

Why Kitchen Plumbing Should Be Handled Properly

Kitchen plumbing combines water supply, drainage, waste connections, appliances and cabinetry in one high-use area.

That means small plumbing problems can become expensive quickly if they are not handled correctly.

Poor kitchen plumbing can contribute to:

• water damage
• swollen cabinetry
• damaged flooring
• recurring blockages
• drainage smells
• appliance leaks
• poor water pressure
• fixture failure
• unnecessary repair costs

A proper assessment helps identify whether the issue is isolated or part of a larger plumbing problem.
