Water hammer is like a 10 car pileup on the freeway. The water inside your pipes has come to a dead stop, and then the water is hitting the wall of the pipes at a high speed, which causes a bang. Why Water Hammer is a Problem The hammer noise isn’t just a

Regulating flow allows a simpler design and minimum pipe sizes as peak flow rates can be specified accurately and can also reduce noise, splashing taps, and water hammer. Manufacturers’ recommendations must be referred to for pressure and flow information when selecting tempering valves and outlets (taps, mixers and shower heads).
In bathrooms of HDB flats, the floor traps have the mosquito trap mechanism that prevents mosquitoes from breeding. When someone uses the bathroom at night, the opening and closing of the traps due to the running water make sounds like marbles dropping.
I am an HDB flat owner and have satisfied the Minimum Occupation Period (MOP). If I have bought a private property, can I choose to live in the private property and rent out my HDB flat instead? 8. What do we have to prepare for key 9.

The water that was rushing to your toilet is now cut off and the pressure causes your pipes to make a loud banging noise. How serious is the banging noise? Water hammer won''t immediately cause any astrophic problems.
21/4/2013· I thought water pipe noises are the cause of the marble falling noises in HDB. Anyway, for your issue, it depends on which part of the pipe that is causing the noise. HDB sometimes will say the issue if caused by upstairs. Quite leychey. Suggest you source

25/3/· If the noise only occurs near a single toilet, the valve that controls the water to fill the pipes is sometimes at fault. While the hum is still due to a pressure problem, older toilets used metal valves that magnify the vibrations to an audible level.

* HDPE pipe may face; PE density of 94% of the salt water, because it is up to 96% of the fresh water on the HDPE pipe filled with water even if the water is suitable to swim in. Therefore, be reduced as far as large parts of the ground may be left floating on the water coined.
10/4/2010· I used to get this irritating noise and get HDB down to my unit to check. It''s leakage at someone flat but it''s difficult to track which unit. Till one day, I heard noise of mending the water pipe at my upper floor and the noise is gone. Your case, it could be your leaking
As you can see from this question opening water pipe tap has hissing noise throughout the house. Noises can also be caused by over pressurization of the pluing system. To determine if the pluing has too much pressure, you can pick up a water pressure gauge from the local hardware store for ~$5.00
