2. Basement waterproofing - Wikipedia

   en.wikipedia.org/wiki/Basement_waterproofing

   The drainage system collects any water entering the basement and drains it to an internally placed sump pump system, which will then pump the water out of the basement. The Federal Emergency Management Agency (FEMA) recommends basement waterproofing with a water alarm and "battery-operated backup pump" as a preventive measure against the high ...

3. Antifreeze - Wikipedia

   en.wikipedia.org/wiki/Antifreeze

   Water pump seal lubricant is also added. Antifreeze was developed to overcome the shortcomings of water as a heat transfer fluid . On the other hand, if the engine coolant gets too hot, it might boil while inside the engine, causing voids (pockets of steam), leading to localized hot spots and the catastrophic failure of the engine.

4. Sump pump - Wikipedia

   en.wikipedia.org/wiki/Sump_pump

   Sump pumps are used where basement flooding may otherwise happen, and to solve dampness where the water table is near or above the foundation of a structure. Sump pumps send water away from a location to any place where it is no longer problematic, such as a municipal storm drain, a dry well, or simply an open-air site downhill from the building (sometimes called "pumping to daylight").

5. Cold trap - Wikipedia

   en.wikipedia.org/wiki/Cold_trap

   Particularly large cold traps are necessary when removing large amounts of liquid as in freeze drying. Cold traps also refer to the application of cooled surfaces or baffles to prevent oil vapours from flowing from a pump and into a chamber. In such a case, a baffle or a section of pipe containing a number of cooled vanes, will be attached to ...

6. Backflow prevention device - Wikipedia

   en.wikipedia.org/wiki/Backflow_prevention_device

   Backflow prevention device. The simplest, most reliable way to provide backflow prevention is to provide an air gap.An air gap is simply an open vertical space between any device that connects to a plumbing system (like a valve or faucet) and any place where contaminated water can collect or pool.

7. Ethylene glycol - Wikipedia

   en.wikipedia.org/wiki/Ethylene_glycol

   So, while providing freeze protection and an increased boiling point, ethylene glycol lowers the specific heat capacity of water mixtures relative to pure water. A 1:1 mix by mass has a specific heat capacity of about 3140 J/(kg·°C) (0.75 BTU/(lb·°F)), three quarters that of pure water, thus requiring increased flow rates in same-system ...
