Plumbers in Sheerness: 7 Checks to Do Before You Call One Out This Winter
Meta title: Plumbers Sheerness | 7 Winter Checks Before You Call
Meta description: Safe winter checks for Sheerness homes before calling a plumber. Practical advice on leaks, boilers, radiators and heating controls.
As colder weather approaches, a few safe checks can help you identify simple problems before they become an emergency. They may also give your plumber useful information if professional help is needed.
This guide is for homeowners, landlords and local businesses in Sheerness, Minster, Queenborough, Sittingbourne and surrounding Kent areas, including ME12, ME9 and ME10.
The checks below only cover tasks that can normally be completed safely at home or on commercial premises. Gas work, boiler repairs and work inside a boiler casing must always be left to a qualified Gas Safe registered engineer.
CHECK 1: FIND YOUR STOPCOCK BEFORE YOU NEED IT
Your stopcock controls the incoming mains water supply. Knowing where it is can help you limit damage if a pipe bursts, a washing machine hose fails or a tap will not stop running.
In many homes, the stopcock is located:
Under the kitchen sink
In a cupboard near the front door
Where the mains water pipe enters the property
In a utility room, garage or cellar
Turn it gently clockwise to check that it moves, then turn it back anti-clockwise to reopen the supply. Do not force a stiff valve. If it is difficult to operate, arrange a repair before winter.
If you find a serious leak:
Turn off the stopcock if it is safe to do so.
Open a cold tap to relieve pressure.
Move electrical items away from water, without touching electrical equipment with wet hands.
Contact a plumber for help.
The WaterSafe winter plumbing advice also recommends knowing where your stop tap is and protecting exposed pipework before freezing weather arrives.
CHECK 2: LOOK FOR SMALL LEAKS AND DRIPPING TAPS
A small drip can become a larger problem when temperatures fall. Before calling for a leaking pipe repair, inspect visible pipework and fittings around your property.
Look carefully beneath:
Kitchen and bathroom sinks
Toilets and cistern connections
Washing machines and dishwashers
Boilers and hot water cylinders
Radiator valves
Outdoor taps
Areas where pipes pass through walls or cupboards
Check for green staining on copper pipes, corrosion, damp patches, mould, swollen cabinets or a musty smell. These signs may indicate a slow leak even when there is no obvious stream of water.
Also check dripping taps. A worn washer, cartridge or loose connection may be straightforward to replace, but persistent dripping should not be ignored. It wastes water and can worsen over time.
Do not remove boiler covers or attempt to repair gas-connected appliances. Make a note of where the moisture is appearing and take a clear photograph for your plumber.
CHECK 3: READ THE BOILER PRESSURE AND FAULT CODE
If you have a combi or sealed heating system, look at the boiler pressure gauge or display when the system is cool. Many systems sit at approximately 1 to 1.5 bar, but your boiler manual should always take priority.
Pressure that is too low may prevent the boiler from operating correctly. Pressure that repeatedly falls after topping up may point to a leak or another system fault.
You can safely:
Read the pressure gauge
Note the boiler make and model
Write down any fault code
Check whether the boiler has power
Follow the manufacturer’s instructions for one reset, where appropriate
Only repressurise the system if you understand your boiler’s instructions and know how the filling loop operates. If the pressure drops again, rises sharply or you are unsure what to do, stop and contact a qualified heating engineer.
A fault code is useful information, not a diagnosis. Repeatedly resetting the boiler can hide an underlying problem. For planned work, our boiler installations service explains how we manage heating upgrades from initial advice through to final checks.
CHECK 4: SEE HOW YOUR RADIATORS HEAT UP
Turn the heating on for a short period and check whether your radiators warm evenly. Keep hands away from very hot surfaces and allow radiators to cool fully before carrying out any adjustment.
A radiator that is cold at the top but warmer at the bottom may contain trapped air. In many homes, it is safe to bleed a radiator using a radiator key:
Turn off the heating and let the radiator cool.
Place a cloth or small container beneath the bleed valve.
Turn the key slowly until you hear air escaping.
Close the valve when water begins to flow steadily.
Check the boiler pressure afterwards.
Do not continue if the valve is damaged, seized or leaking. If several radiators remain cold, the issue may involve a valve, pump or wider heating fault rather than trapped air.
Landlords and residents in managed buildings should also check whether their heating provider has specific instructions. If you are unsure, ask a professional before bleeding radiators or adjusting system pressure.
CHECK 5: INSPECT THE CONDENSATE PIPE IN COLD WEATHER
Modern condensing boilers discharge water through a plastic condensate pipe. Where part of this pipe runs outside, it can freeze during a cold spell and cause the boiler to lock out.
Look for:
A white or grey plastic pipe leaving the boiler
Ice or frost around the external section
Water that is not draining
A boiler fault code appearing during freezing conditions
If the pipe is accessible from ground level and you are confident it is frozen, you can apply warm water or a hot water bottle to the affected section. Never use boiling water, a naked flame or a blowtorch. Boiling water can damage plastic pipework, while flames are unsafe.
Once the pipe has thawed, follow your boiler manual to reset the appliance once. If it locks out again, the pipe repeatedly freezes or the external section is difficult to reach, call a Gas Safe registered heating engineer.
The Energy Saving Trust provides wider guidance on efficient home heating, while your boiler manufacturer should provide model-specific instructions.
CHECK 6: PROTECT OUTDOOR TAPS AND EXPOSED PIPEWORK
Outdoor taps are easy to overlook, particularly when they are at the rear of a property, in a courtyard or beside a commercial building.
Before the coldest weather arrives:
Disconnect garden hoses.
Close the internal isolation valve supplying the outdoor tap.
Open the outdoor tap briefly to drain remaining water.
Check exposed pipework for missing or damaged insulation.
Look for cracks, drips or loose fittings.
Protect accessible pipework with suitable insulation.
Do not wrap insulation around a wet or leaking pipe and assume the issue is solved. If you find a split pipe or water continues to escape, turn off the supply and arrange professional help.
For homes in Sheerness and the Isle of Sheppey, wind and exposed locations can make external pipework particularly vulnerable. A tidy inspection now can help prevent an inconvenient winter burst.
CHECK 7: TEST YOUR HEATING CONTROLS AND TIMERS
Sometimes a heating system is working correctly but is not receiving the right instruction to turn on. Check the controls before assuming that the boiler has failed.
Confirm that:
The programmer or timer is set to the correct day and time.
The heating is scheduled to come on.
The room thermostat is set above the current room temperature.
Wireless thermostat batteries are not flat.
Thermostatic radiator valves are not set to zero or frost protection.
The boiler has power at its local isolation switch.
The consumer unit has not tripped.
Run the heating briefly and listen for unusual noises. If the controls show heat demand but the boiler does not respond, make a note of what you have checked and contact a heating professional.
Small control problems can be frustrating, but testing them first helps avoid confusion and gives your plumber a clearer starting point.
WHEN YOU SHOULD STOP CHECKING AND CALL A PROFESSIONAL
Some problems should not be treated as DIY jobs. Contact a qualified engineer if you notice:
A smell of gas
A carbon monoxide alarm sounding
Soot marks around a gas appliance
A boiler that repeatedly locks out
Repeated pressure loss
A significant water leak
A damaged flue or condensate connection
Unusual banging, roaring or overheating
Any fault inside the boiler casing
If you smell gas, avoid electrical switches and naked flames, ventilate the property if safe, leave if necessary and call the National Gas Emergency Service on 0800 111 999. Do not use the appliance again until it has been checked.
The Gas Safe Register explains how to check an engineer’s registration and work categories. The Health and Safety Executive’s domestic gas guidance also confirms the importance of using appropriately registered and competent engineers for gas work.
WINTER PREPARATION FOR LANDLORDS AND COMMERCIAL PREMISES
Landlords should check that tenants know where the stopcock is and that heating controls are easy to operate. Arrange any due gas safety checks and servicing before colder weather places greater demand on the system. The HSE explains who can carry out landlord gas safety checks in its official guidance.
For offices, gyms, hospitals and other commercial premises, winter preparation should include:
Checking plant rooms and service cupboards for visible leaks
Protecting exposed pipework in unheated areas
Testing heating timers and control zones
Confirming that critical areas receive adequate heat
Checking outdoor taps and external service routes
Recording boiler fault codes before requesting a visit
Arranging gas safety and maintenance work with suitable professionals
