Outside taps and garden plumbing
An outside tap needs its own isolation valve and, in colder areas, either an internal shut-off you can drain down for winter or a proper anti-frost design — a poorly installed one is a common cause of a burst pipe in cold weather. This is separate from the electrical requirements for any pond or irrigation pump also being installed.
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.
Common plumbing myths, busted
"A dripping tap is just cosmetic" — left long enough it wastes real water and can damage the fitting further. "Any handyman can fit a boiler" — boiler work involving gas connections legally needs a Gas Safe engineer, not just a plumber. "Bleeding a radiator fixes all heating faults" — it only helps with trapped air, not pressure or pump issues.
Combi vs system vs conventional boilers
A combi boiler heats water on demand with no separate tank, suits smaller properties with one bathroom. A system boiler uses a hot water cylinder but no cold water tank, better for higher demand. A conventional (regular) boiler uses both a cylinder and a tank, common in older properties and useful where mains pressure is poor.
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.
What is a power flush and do you need one?
A power flush clears sludge and debris from a central heating system's radiators and pipework using a pumped chemical flush — usually recommended if radiators are cold at the bottom, or before installing a new boiler onto an older system, so the new boiler isn't immediately clogged by old sludge.
Plumbing responsibilities for landlords
Landlords are responsible for keeping water and heating systems in safe working order, and if there's a gas boiler, a valid annual Gas Safety Certificate is a legal requirement, not optional. A burst pipe or heating failure in a rented property is generally treated as an emergency repair the landlord must address promptly.
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.
