Kitchen Plumbing in Oxford
The kitchen is one of the busiest rooms for plumbing. Hot and cold supplies, the sink waste and the water connections for appliances all share a small space under the worktop. We help homes and businesses across Oxford with kitchen plumbing repairs, connections and changes.
Let us know what is happening, or what you are planning for the kitchen, and we will explain how we can help.
What Kitchen Plumbing Covers
Most kitchen plumbing falls into three groups. A fault or a change may involve one of them or all three.
Water supplies
The cold mains supply, usually with the inside stopcock nearby, and the hot supply that feed the sink tap and any appliances. Isolation valves let each one be turned off on its own.
Wastes and drainage
The sink waste, the trap below it and the waste pipe that runs to the outside drain. Appliance wastes often join this same route.
Appliance connections
The cold or hot feed and the waste hose connection for a washing machine or dishwasher. This is plumbing work, separate from the appliance itself.
Where Kitchen Plumbing Faults Tend to Show
Kitchen leaks and faults often appear in a few familiar places. Where the water shows up is a useful clue, but it does not always mark the source.
Under the sink
Supply pipes, tap connections, isolation valves, the waste and the trap all meet here. Faults that are clearly with the sink itself are dealt with on our sink repair page.
Around the tap
Drips, stiffness or a loose tap point to the tap rather than the pipework. Our tap repair service deals with those. If the hot tap takes a long time to warm up, the length of the pipe run is often the reason, as covered in why a kitchen hot tap takes so long to run hot.
Behind appliances
Connections behind a washing machine or dishwasher are easy to forget. A slow drip here may go unnoticed until the floor or plinth is damaged. Appliance valves that snap shut quickly can also make pipes knock, as explained in why kitchen pipes bang when the washing machine fills.
Hidden pipe runs
Pipes often run behind units and under plinths. A leak here may only show as a swollen kickboard, a damp smell or water creeping out from under the units.
One Fitting or the Wider Pipework?
A fault that affects only the sink, or only one appliance, is usually local to that fitting. When several things go wrong together, the cause may be shared.
For example, if both the sink and the dishwasher drain slowly, the shared waste pipe could be involved. If the sink simply will not empty, our blocked sink service is the place to start. Weak flow at the kitchen tap does not necessarily mean low mains pressure either, as a partly closed valve or a restriction in the tap itself can have the same effect.
Looking at the kitchen plumbing as a whole helps us find the real cause rather than treating one symptom.
Appliance Water and Waste Connections
Washing machines and dishwashers need a water supply, usually through a dedicated appliance valve, and a waste connection, often into a trap under the sink or a standpipe. Hoses that are kinked, worn or pushed too far behind the appliance can start to leak over time.
Our work here is limited to the plumbing: the supply valves, pipework and waste connections. Faults inside the appliance, its electrics or its controls are a job for the manufacturer or an appliance engineer, and gas cookers and hobs are outside the scope of this plumbing service.
If water is leaking near sockets or an appliance that is plugged in, stay away from it and call in suitable professional help.
Changing or Refitting a Kitchen
A new kitchen often means the plumbing needs to change too. Moving the sink to a different wall, adding a second sink or putting the dishwasher in a new spot can all mean extending supply pipes and planning a new waste route with enough fall to drain properly.
It helps to involve a plumber early, before units go in. Once cabinets and worktops are fitted, pipe runs become harder to reach. We can work through the plumbing side of the plan with you and fit in around your kitchen fitter and other trades.
Even without a full refit, swapping a sink or tap can show up older pipework or valves that are worth replacing while everything is accessible.
What Affects the Cost of Kitchen Plumbing
Kitchen jobs range from a single connection to a full rearrangement, so a price depends on seeing the job first. It mostly comes down to how much plumbing is affected, how many fittings are involved and how easy the pipes are to reach.
Pipework behind fitted units or under the floor takes longer to reach than an open cupboard. New waste routes, extended supplies and replacing older fittings all add to the work. Some leaks need tracing before the cause is clear.
As our local plumbing services reach well beyond the kitchen, tell us about anything else that needs doing at the same time.
Kitchen Plumbing FAQs
What does kitchen plumbing include?
It includes the hot and cold supplies, isolation valves, sink waste, trap and waste pipe, plus the water and waste connections for appliances such as washing machines and dishwashers.
Why is there water coming from under my kitchen units?
It could come from the sink plumbing, an appliance connection, a hidden pipe run behind the units or the waste. The source needs finding before the right repair is clear.
Can you connect a new washing machine or dishwasher?
We can provide the plumbing side, such as the supply valve and the waste connection. Electrical work and repairs inside the appliance are separate and need the right specialist.
Can my kitchen sink be moved to a different wall?
Often, yes. It usually means extending the supply pipes and creating a new waste route with enough fall. What is possible depends on the layout and where the drainage runs.
Should the plumbing be done before or after the new units go in?
Usually before. Running new pipes and wastes is simpler while walls and floors are open, with final connections made once the units and worktops are fitted. Sink position, appliance connections and isolation valves are covered in what plumbing to think about when fitting a new kitchen.
Is it worth repairing old kitchen pipework?
A small repair can make sense if the rest of the pipework is sound. If the pipes or valves are in poor condition, replacing a section while the kitchen is open may be more practical.
