Water expands when it freezes, which causes pipes to burst. Pipes are strong, but the pressure imparted by solidifying water is often too much for them to bear.Know More
Most substances take up less space in their solid states than when they are in liquid form; water is an exception to this. In solid form, atoms of a substance are close together. In liquid form, atoms can spread out a bit, and chemicals expand significantly when they are in gaseous form. However, when water freezes, it forms a crystalline grid that causes it to expand.
The crystalline structure of ice makes it susceptible to cracking and shattering, but it also gives it more strength. Pipes are designed to withstand the force of ice formation, but few are able to withstand the pressure imparted when a significant length of ice forms.
Water's expansion when it undergoes a phase transition to a solid is part of the reason why ice floats, but there are other causes. Water will often trap air when it freezes and form a strong barrier than prevents this air from being released. Ice can also have a hollow core, and it will remain buoyant if this core is not breached.Learn more about Plumbing
To thaw a frozen water pipe in a mobile home, ensure the pipe's faucet is open to let the melted water escape and either wrap or warm the pipe with heat tape or an electric heater. Make sure someone is home when the pipes thaw in case the pipe was damaged from the freeze.Full Answer >
To prevent frozen pipes, leave a trickle of warm water running from a faucet on nights when the temperature drops. The slow flow of water prevents ice from blocking pipes and also prevents freezing damage. In addition, leaving under-sink cabinets open allows warm air to circulate around pipes and keeps their temperature from dropping into the freezing range.Full Answer >
One of the most common causes of humming pipes after flushing a toilet is debris trapped in an inlet valve. Water carries small stones, calcium deposits and solder to the valve area which traps them, resulting in the annoying noise.Full Answer >
Remove air from water pipes by opening each faucet in the home systematically, beginning with the one closest to the water main. Once all valves are open, start closing them one at a time in the same order.Full Answer >
