Building equipment, opened up
Sump pumps, roof drains, pipe expansion joints and groundwater wells cut open and explained part by part, so you can follow every drop of water and every millimetre of movement through a building.
How a Sump Pump Basin & Float Switch Works
Water fills the pit, lifts the float, trips the switch and is pumped up and out.
How a Roof Drain Water Trap Works
Rain runs into a domed strainer and down through a U-bend whose water seal blocks sewer gas.
How a Pipe Expansion Joint Works
A corrugated bellows flexes to absorb thermal movement, with tie rods and a liner sleeve.
How a Groundwater Well Screen & Sand Filter Pack Works
Aquifer water seeps through a gravel pack and slotted screen, then is pumped up to the surface.
