Blocked drains — causes and what a plumber checks
Slow-draining sinks are usually a local blockage (grease, hair, food waste) that a plumber can often clear with rodding or a drain snake. A blockage affecting multiple fixtures at once, or gurgling sounds from other drains, points to something further down the system — sometimes needing a drain camera survey rather than guesswork.
Aftercare after plumbing work
After a boiler installation or bathroom refit, you should receive a benchmark/commissioning checklist (for a boiler) or a written summary of the work done, which you'll want if you make an insurance claim or sell the property later. Keep it with your household paperwork alongside any appliance warranties.
How plumbing quotes work
Describe the job, including whether it's an emergency, a planned repair, or a full installation, and mention access — under a suspended floor is very different from behind fitted units. Plumbers use this for an initial estimate; the final price is usually confirmed once they've seen the fault or the space in person.
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.
Finding a hidden leak
A leak inside a wall or under a floor isn't always obvious until it shows as a damp patch or a high water bill. Plumbers use damp meters, thermal imaging or (for harder cases) tracer gas to locate a hidden leak without having to open up an entire wall speculatively — worth asking about before agreeing to exploratory work.
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.
Plumbing regulations, FAQ
Do I need a certificate for a new bathroom? There's no single certificate like Part P for electrics, but any work must comply with Water Fittings Regulations, and gas-connected work needs a Gas Safe engineer. Can I do my own plumbing? Straightforward repairs, yes; anything affecting the public water supply (like a new connection) should go through a WaterSafe-approved plumber.
Do you know where your stopcock is?
Every property has a main stopcock (usually under the kitchen sink, though sometimes in a different location in older or converted properties) that shuts off the water supply. Knowing where it is and checking it turns freely, before you need it in an emergency, is one of the simplest things a homeowner can do.
