Plumber in Serangoon

That depends on which pipe it is. PUB says the sanitary drain-lines on private premises are private sewers, owned by the premises' owners, who are responsible for maintaining them. But PUB also explains that in old housing estates, some developers laid sewers inside private land to serve a row of houses, typically at the back, connecting the kitchen and toilet drain-lines to the public sewerage system. In PUB's words, a public sewer within your premises is a common utility serving your house and the adjacent houses, and PUB maintains the public sewers. The choke we cleared at a landed house in Serangoon Gardens was inside the house, at the toilet bowl.

Yes, in two steps if needed. In Serangoon we have made a first visit just to stop the water discharging at the heater and isolate its supply, and then done the replacement: a new 40-litre Rheem, the PPR hot and cold pipes changed to stainless steel, and every connection pressure-tested before the heater was filled and commissioned. Our guide price for a new storage heater starts from $500.

It may only need cleaning. In one Serangoon house we took the wash basin's bottle trap apart, cleaned out the build-up and refitted it. At another we fitted a new PVC bottle trap. Both were tested for leaks. Send us a photo of the trap under your basin and we confirm the price before we start.
