How long does plumbing work take?
A tap or valve replacement is usually under an hour. A full bathroom refit commonly takes 5 to 10 working days depending on scope, plus time for tiling and decorating that isn't part of the plumbing work itself. A boiler swap is typically a one-day job if it's a straightforward like-for-like replacement.
Plumbing and selling your home
Buyers' solicitors sometimes ask about the age and condition of the boiler and any recent plumbing work, particularly if there's visible evidence of a past leak or repair. Keeping paperwork for any significant plumbing work — a new boiler, a bathroom refit, a burst pipe repair — makes this a much smoother conversation.
Plumbing emergencies — what to do first
For a burst pipe or major leak, turn off the water at the stopcock (usually under the kitchen sink or where the supply enters the property) before calling anyone — this limits water damage while you wait. For no hot water or heating, check the boiler pressure gauge first; a common cause is low pressure, which some homeowners can safely top up themselves via the filling loop.
Red flags in a cheap plumbing quote
A quote significantly below the others is worth questioning before accepting — check it specifies the same quality of parts (a boiler make/model, not just "a boiler"), includes making good after any pipework is exposed, and covers testing before the job is signed off as complete.
Shared water supplies in flats and conversions
In a converted property, check whether your flat has its own independent stopcock and supply, or shares one with other flats via a communal system. A shared supply can mean a repair affects your neighbours too, and sometimes needs freeholder involvement before work starts.
Low water pressure — common causes
Low pressure can come from a partially closed stopcock, a fault with the water company's supply, scale build-up in old pipework, or (for a shower specifically) the type of shower valve fitted. A plumber can usually diagnose which of these it is by checking pressure at more than one fixture, rather than assuming it's the mains supply.
Plumbing in a washing machine or dishwasher
Both need a cold water supply, a drain connection, and in most cases their own isolation valves so they can be disconnected without turning off water to the whole property. Using a shared valve with another appliance is a common shortcut that makes future repairs more disruptive than it needs to be.
Common plumbing jobs
Plumbers handle everything from a dripping tap to a full bathroom re-pipe: fixing leaks, clearing blocked drains, replacing taps and valves, fitting new bathroom suites, repairing or replacing radiators, and connecting appliances like washing machines and dishwashers. Emergency work (burst pipes, no hot water) is usually handled separately from planned jobs like a bathroom refit.
