PLUMBING BASICS
Advice to help you get organised, understand what things cost and find a reliable Plumber.
TIME OF YEAR TIPS
Before winter: check outside tap isolation valves, and consider draining down any external pipework not in regular use. Before summer: check garden irrigation and outside tap connections for wear, since these see much more use once the weather turns. A five-minute check avoids most seasonal callouts.
WORTH KNOWING
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.
UNDERSTANDING THE JOB
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.
WORTH KNOWING
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.
SEASONAL ADVICE
Pipes in unheated spaces — lofts, garages, outbuildings — are the most common source of a winter burst pipe once temperatures drop below freezing for a sustained period. Lagging exposed pipework and keeping heating on a low constant setting during a cold snap, rather than off, are the two most effective preventive steps.
REGULATIONS & SAFETY
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.
GOOD TO KNOW
An unexplained rise in your water bill, or a water meter that keeps ticking over when nothing's running in the property, is one of the clearest early signs of a hidden leak. Most water companies can help identify whether the leak is on your side of the meter (your responsibility) or theirs.
RULES & STANDARDS
WaterSafe is the umbrella body for the UK's Approved Contractor Person schemes (including APHC, CIPHE, WIAPS and SNIPEF). A WaterSafe-approved plumber has been assessed on their knowledge of the Water Fittings Regulations, which exist to stop poor installation work or substandard products contaminating the drinking water supply — not just general plumbing competence.
LOCAL GUIDE
Bow is a large town in the London region within Greater London and covered by the E3 postcode district. Population data are not supplied. Borough services handle planning, building regulation and permits for the area. The E3 postcode is useful when searching for trades because it narrows results to contractors who routinely work in east London and who understand E3’s parking, delivery restrictions and river-proximate properties. In such an inner‑city large‑town, expect a mix of period terraces and newer developments; trades operating in Bow will typically have experience with party‑wall matters, loft conversions and coordinating works in constrained roads. Ask potential contractors about their experience with any required local consents and with staging deliveries to minimise disruption.
Plumbing in Bow (E3) frequently involves working in tight spaces and coordinating with neighbouring properties because period terraces and flats are common; this affects how plumbers manage access for pipe replacements or bathroom refits. Older London properties may have ageing copper or lead pipework that requires careful replacement and testing, while newer builds more often need first‑fix work for loft conversions or contemporary kitchens.
WRAS‑approved fittings are a legal requirement for mains water work to ensure public‑supply safety, and unvented cylinder installations must be handled by a G3‑qualified installer due to the higher pressures and safety controls involved. Drainage runs can be complex in terraced areas where connections feed to shared sewers, so choose a plumber experienced with local drainage layouts. When hiring a plumber in Bow, ask for WRAS compliance, G3 credentials where relevant, and examples of work in similar confined or party‑wall settings.
