Helpful hint: dry the cupboard floor and place paper towel down to show where water appears first.

Focused service
Kitchen plumbing service
Kitchen faults often start inside the cupboard, around the trap or where appliances share the sink waste route.Trap and waste pipe problems
Loose traps, misaligned wastes and worn seals can create leaks, smells and slow drainage under the sink.
Helpful hint: do not keep tightening plastic trap nuts if the pipe is misaligned; it can worsen the leak.
Blocked kitchen drains
Grease, food debris, coffee grounds and soap can restrict kitchen waste lines before a full overflow happens.
Helpful hint: mention whether the washing machine or dishwasher also drains into the same sink trap.
Dishwasher and appliance points
Appliance water feeds and waste hoses need secure routing, shut-off access and protection from kinks.
Helpful hint: leave the appliance accessible so the hose route can be checked behind and under the cabinet.
Under-sink valves and isolation
Old valves under the sink can drip, seize or fail to close when a leak starts.
Helpful hint: do not force a stiff valve; tell us whether it turns, drips or feels loose.
Cupboard and floor protection
Small kitchen leaks can swell boards, damage kick plates and spread under flooring before they are noticed.
Helpful hint: send a photo from inside the cupboard with stored items removed so the leak area is visible.

FAQ
Kitchen Plumbing questions
Clear answers for common questions before booking the service.What are common kitchen plumbing problems?
Common problems include mixer leaks, blocked sink wastes, leaking traps, dripping valves, appliance hose leaks and water-damaged cupboards.
Why is my kitchen sink draining slowly?
Slow drainage often comes from grease, food debris, soap build-up, trap restriction or a shared appliance waste route.
Can dishwasher waste block the sink?
Yes. A dishwasher connected into the sink trap can contribute to smells, gurgling or backup if the spigot or trap is restricted.
Why is there water inside my sink cupboard?
Water can come from mixer tails, trap seals, waste joints, dishwasher hoses, washing machine hoses or under-sink valves.
Should I use chemical drain cleaner in a kitchen sink?
It is usually better to avoid harsh chemicals, especially when water is standing in the sink or trap. Mechanical clearing is often safer.
Can a kitchen mixer be repaired?
Sometimes. The answer depends on the mixer type, cartridge, seals, body condition and whether the leak comes from the tap or the connections.
Do under-sink valves need replacing?
Old, leaking or seized valves should be considered for replacement so future leaks can be isolated quickly.
Why does my kitchen sink smell?
Smell can come from trap issues, food build-up, appliance hose routing, poor venting or a waste connection problem.
Can a washing machine connect in a kitchen?
Yes, where water feed, waste route, hose support and shut-off access are suitable.
What should I prepare before a kitchen plumbing visit?
Clear the sink cupboard, note which fixture causes the problem and avoid using the affected waste route if it is backing up.
Can kitchen leaks damage flooring?
Yes. Water can travel under kick plates and flooring before the leak becomes obvious.
What is a trap spigot?
A trap spigot is the connection point on some sink traps for appliance waste hoses such as dishwashers.
Why does the sink gurgle when an appliance drains?
Gurgling can point to a restricted trap, poor hose routing or a waste line struggling to accept appliance discharge.
Can kitchen plumbing be part of a renovation?
Yes. Renovations often need sink position checks, mixer feeds, appliance points, waste fall and valve access planning.
When is a kitchen plumbing fault urgent?
It is urgent when water is actively leaking into cupboards or floors, a drain is overflowing, or water is near electrical appliances or plugs.
