Sin Lian Sen Trading & Services is a plumbing business at 446 Hougang Ave 8 in Hougang, Singapore, with a 4.9 rating on Google.
Plumbing is a trade where the visible fault is rarely the whole story. Around Singapore's HDB estates, the usual call-outs are choked sinks and floor traps, dripping taps and water heater trouble, and a good plumber traces the cause rather than just clearing the symptom, since a drain that blocks again within weeks usually points to a problem deeper in the pipe run. Two things are worth knowing: work on incoming water supply must be done by a PUB-licensed plumber, and a ceiling leak may come from the block's common property rather than your own pipework, in which case the town council looks after it.
For households around Hougang, Sin Lian Sen Trading & Services is a well-rated neighbour to call when a tap, trap or heater plays up.
