Plumber in Sha Tin

Know where your main shut-off valve is, don't pour fats down the kitchen sink, use hair catchers in showers, and fix small drips early — a dripping tap is a washer today and a corroded valve seat next year. In Sha Tin, ask your plumber during any visit to point out ageing flexi-hoses and valves; braided hose failures are one of the most common causes of home flooding.

It depends on the country and the type of work. Many countries license plumbing as a trade or restrict specific work — gas, drinking-water connections, hot-water systems — to registered plumbers. Even where general plumbing is unlicensed, hiring someone insured and registered protects you if the repair fails and causes water damage.

Plumbers handle supply pipes, fixtures, and internal waste pipes. Drainage specialists handle underground drains, sewers, jetting, and camera surveys. For a recurring underground blockage or collapsed drain, a drainage firm with a jetting rig and CCTV camera is usually cheaper and faster than a general plumber.

A call-out fee covers the plumber's travel and the first period on site (often 30-60 minutes). It is standard practice in most countries, especially for emergency and after-hours work. What varies is whether it is credited against the job if you proceed — ask this before booking, and get the fee stated up front.

Tap or valve replacement: 30-60 minutes. Toilet replacement: 1-3 hours. Unblocking a drain: 30 minutes to 2 hours depending on severity. Water heater replacement: half a day. Bathroom re-piping: one to several days. Plumbers usually charge minimum call-outs, so batching several small fixes into one visit is the cheapest way to buy their time.

Reputable plumbers warrant their labour — commonly 3-12 months on repairs, longer on installations — separate from the manufacturer's warranty on parts. Get the warranty stated on the invoice. A plumber who won't put any guarantee in writing is telling you something.

Per-job pricing is standard: unclogging (通渠) runs HK$300-HK$1,200 depending on severity, tap or valve replacement HK$300-HK$800, and toilet replacement HK$800-HK$3,000 including a standard unit. Emergency night calls carry a 50-100% premium.

The owner of the source of the leak is responsible, but proving the source is the hard part. Start with your management office, which can arrange inspection; unresolved cases go to the Buildings Department/FEHD Joint Office for inter-floor water seepage. Keep photos and correspondence — these disputes are slow.
