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
A shower diverter is a valve allowing users to install multiple shower heads in a single shower. The function is to divert the single water flow into one or more additional shower heads or handsets.Full Answer >
A water shutoff valve refers to a small local valve that is used to control the water flow to a plumbing fixture. This type of valve is commonly found under the sink or under the toilet tank.Full Answer >
The main difference between a British Standard Pipe Taper and a National Pipe Taper threads is that the NPT thread have a 60-degree included angle compared to the 55-degree included angle on the BSPT thread. NPT threads also have flattened peaks and valleys called a Sellers form, while the BSPT have rounded peaks and valleys called the Whitworth form.Full Answer >
To replace a shower valve, remove the valve trim, then remove the old valve. Install the new valve by cleaning the pipes, removing the plastic cartridge from the valve, applying flux and inserting the pipes. Use a torch to solder the connections.Full Answer >
