Kitchen Sink Installation Glasgow
A new kitchen sink installation involves connecting the supply pipes (hot and cold) and routing the waste pipe to the drain. For a like-for-like replacement in the same position, this is typically a 1 to 2 hour job. For a new sink in a new position for example, moving the sink to a kitchen island or changing the layout during a kitchen renovation the job involves running new supply pipework and a new waste run to the nearest soil pipe or gully, which takes 2 to 4 hours depending on distances and access.
What kitchen sink installation includes
- Isolation of the existing water supply turning off the cold supply and the hot supply from the boiler or cylinder
- Removal of the existing sink and tap fittings (if replacing)
- Supply pipe connections typically 15mm copper or push-fit to the hot and cold taps
- Waste connection 40mm waste pipe from the sink trap to the standpipe, gully, or soil stack
- Fitting the new sink and tap if supplied by the customer
- Pressure test run both taps and check all connections are dry
Things that affect the cost
- Whether the sink is in the same position or a new location new position adds supply runs and potentially a new waste route
- The material of the existing pipework copper is straightforward; old iron or lead pipe may need replacing
- Whether the waste run requires cutting through cabinetry or floor to reach the drain
- Whether the tap is supplied by the customer or quoted separately
Dishwasher and Washing Machine Connections
Connecting a dishwasher or washing machine to an existing supply and waste is one of the most common kitchen plumbing jobs in Glasgow and one of the most frequently done incorrectly as a DIY project, resulting in slow leaks that cause cabinet damage over time.
Dishwasher connection
A dishwasher requires a cold water supply (15mm connection with an inline service valve), a waste outlet connected to the kitchen sink waste or a dedicated standpipe, and an electrical supply (not part of the plumbing scope). A professional connection takes 1 to 2 hours and includes:
- Fitting a 15mm service valve to the cold supply under the sink or behind the appliance position
- Connecting the dishwasher supply hose to the valve
- Connecting the waste hose to a dedicated spigot on the sink trap, or fitting a new trap with a spigot if the existing trap does not have one
- Fitting a waste standpipe if the unit is not adjacent to the sink
- Running the machine through a test cycle and checking all connections
Washing machine connection
A washing machine connection is similar to a dishwasher but typically requires both hot and cold supply connections on older machines, or cold only on modern machines with an internal heater. The waste runs to a standpipe (a capped section of 40mm waste pipe) rather than directly to the sink trap.
- Hot and cold service valves fitted (or cold only for modern machines)
- Supply hoses connected
- Dedicated 40mm standpipe fitted if not already in place this is a separate waste from the kitchen sink
- Full test cycle run to check for leaks at all connections
In our experience across Glasgow, the most common fault we fix on DIY-connected appliances is the waste hose sitting too low in the standpipe allowing water to siphon continuously or flow back into the machine. A correctly installed standpipe has the waste hose end sitting at 600 to 900mm above floor level.
Kitchen Tap Replacement and Upgrades
Replacing kitchen taps whether swapping a standard mixer tap, upgrading to a pull-out spray tap, or fitting a boiling water tap is a straightforward job when the sink is remaining in the same position. The main variable is tap quality and supply hose specification.
Standard mixer tap replacement
- Isolate hot and cold supplies under the sink using the inline service valves if there are no service valves under the sink (common in older Glasgow properties), the stopcock will need to be turned off
- Disconnect old tap supply hoses and remove the tap from the sink
- Fit new tap, connect new supply hoses to the service valves
- Turn on and check run both hot and cold, check for leaks at supply hoses and at the tap body
Boiling water tap installation
Boiling water taps (Quooker, Zip HydroTap, and similar) require a cold water supply connection and a dedicated power supply for the under-sink tank unit. The plumbing element involves connecting the cold supply to the unit and running a hot water line from the unit up to the tap. The electrical connection must be carried out by a qualified electrician this is not part of the plumbing scope.
Installation of a boiling water tap typically takes 2 to 3 hours for the plumbing element, plus the electrician’s time for the spur. Most manufacturers recommend professional installation to maintain the warranty.
Full Kitchen Plumbing Refit
For a full kitchen renovation where the layout is changing new island with sink, relocated hob, new appliance positions the plumbing element is usually carried out in two stages:
First fix (before the kitchen is fitted)
- Cap off all existing supply and waste connections at the correct positions
- Run new 15mm supply pipes (hot and cold) to the new sink position, dishwasher position, and any other appliance positions
- Run new 40mm waste pipes from the new sink and appliance positions to the soil stack or external drain
- Leave capped tails protruding at the correct height and position for the kitchen fitters to work around
Second fix (after the kitchen is fitted)
- Connect taps to the supply tails hot and cold
- Connect sink waste to the trap and route to the waste run
- Connect all appliances dishwasher, washing machine, boiling water tap
- Full pressure test run all taps and appliances simultaneously, check every connection
For a full kitchen refit, coordinating the plumber’s visits with the kitchen fitter’s schedule is important the plumber needs to complete first fix before cabinets go in, and second fix after the units are in position and the sink is fitted. We work alongside kitchen fitters across Glasgow and are used to coordinating the sequencing of this kind of project.
Common Kitchen Plumbing Problems in Glasgow Homes
Slow-draining kitchen sink
The most common kitchen plumbing problem we attend in Glasgow is a slow-draining or blocked kitchen sink. The blockage is almost always in the trap (the U-bend under the sink) or in the waste run shortly after it, caused by grease, food debris, and detergent residue building up over time. A plunger and drain cleaner resolves minor blockages. A persistent slow drain usually indicates a partial blockage in the trap or waste run that needs clearing mechanically.
Dripping kitchen tap
A dripping kitchen tap is usually a worn ceramic cartridge or O-ring inside the tap body. For modern ceramic disc taps, cartridge replacement is typically the fix the cartridge is a sealed unit that is replaced as one piece. In older Glasgow properties with traditional brass tap bodies and rubber washers, the washer is replaced. Both are quick jobs if the water can be isolated under the sink.
Leak under the kitchen sink
Leaks under the kitchen sink are most commonly at one of three points: the supply hose connections to the service valves, the tap body where the supply hoses connect, or the sink waste at the trap. Most under-sink leaks are slow and go unnoticed until cabinet damage appears by which point the leak has often been running for weeks. If you notice water damage inside the kitchen cabinet, check all connections immediately before further damage occurs.
No hot water at the kitchen tap
If the kitchen tap has no hot water but the rest of the property does, the most likely cause is a faulty service valve on the hot supply under the sink that has seized in the closed position. If the whole property has no hot water, the issue is with the boiler or hot water cylinder see our emergency heating repair guide for next steps.
Glasgow-Specific Considerations
Older Glasgow Kitchens Lead and Iron Pipework
Kitchens in Glasgow properties built before the 1970s may have original lead or iron supply pipework. If kitchen plumbing work exposes lead pipework particularly the section running to the sink we will always recommend replacing it rather than reconnecting to it. Lead in drinking water is a health concern, and older lead pipework is also a burst risk as it ages. If you have an older Glasgow property and have never had the kitchen pipework inspected, a plumbing survey is worthwhile before any kitchen renovation.
Tenement Kitchens Shared Waste Stacks
In Glasgow tenement flats, the kitchen waste typically connects to a shared soil stack that runs vertically through the building. This shared stack is the responsibility of all owners in the building (managed by the factor). If kitchen waste work involves connecting to or extending from this shared stack, it is worth confirming with your factor whether any consent is required. Individual connections to a private external waste run do not require this consent.

Frequently Asked Questions
How much does kitchen plumbing cost in Glasgow?
A simple kitchen plumbing job such as a tap replacement or appliance connection costs £80 to £150. A sink installation in a new position costs £150 to £300. A full kitchen plumbing refit for a new or relocated kitchen layout costs £400 to £800 or more depending on the scope. All jobs are priced by written quote before work begins.
Can I connect my own dishwasher or washing machine?
Connecting a dishwasher or washing machine is not gas work and is not legally restricted in the same way a homeowner can legally connect their own appliance. However, the most common call-out we receive is to fix a DIY-connected appliance that is leaking or has been connected to the waste incorrectly. A professional connection costs £80 to £150 and comes with a check that everything is correctly fitted which protects your kitchen cabinets from the slow water damage that a faulty connection causes over months or years. See Citizens Advice for guidance on your rights if an appliance connection causes damage.
Do I need a plumber to install a boiling water tap?
Yes most manufacturers of boiling water taps (Quooker, Zip HydroTap, etc.) require professional installation by a qualified plumber to maintain the warranty. The plumbing element is not restricted by law, but the electrical element (wiring the under-sink unit to a switched spur) must be carried out by a qualified electrician. We carry out the plumbing element and coordinate with an electrician for the spur connection where needed.
How long does kitchen plumbing take?
A tap replacement or appliance connection typically takes 1 to 2 hours. A sink installation in a new position takes 2 to 4 hours. A full first-fix and second-fix kitchen plumbing refit can take a full day or more depending on the number of connections and the complexity of the new layout. Your written quote will confirm the expected duration.
Why is my kitchen sink draining slowly?
A slow-draining kitchen sink is almost always caused by a build-up of grease, food debris, and detergent residue in the trap (the U-bend under the sink) or in the waste run shortly after it. Try a plunger and drain cleaner first. If the problem persists, the trap or waste run needs clearing mechanically a job that takes around an hour.
Do I need a plumber for a kitchen renovation in Glasgow?
Yes if your kitchen renovation involves moving the sink, adding appliance connections, or changing the waste run, a plumber is needed for the first-fix and second-fix stages. If the kitchen is being refitted in exactly the same position with no layout changes, a competent kitchen fitter can often manage the disconnection and reconnection of existing connections. For anything involving new pipework, new waste runs, or appliances in new positions, a qualified plumber is the right choice.
