Deciphering the Plumber’s Jargon: A Glossary for the Uninitiated in Plumbing Terminology

Have you ever found yourself nodding along to a plumber’s lingo-filled explanation, only to realise you’re lost in a maze of terms like “TMV” and “S-trap”? 

Well, fret not! We’re here to transform you from a plumbing novice to a conversant aficionado. It’s time to ditch the “Fake it ‘til you make it” approach and truly understand the language of the trade with Whywait Plumbing’s comprehensive glossary.

So, before you can say “pass the shifter,” let’s dive into the vernacular of valves and the prose of pipes.

The Language of Pipes and Valves: Decoding “Plumberese”

Septic tank: Think of it as a subterranean cafeteria where bacteria dine on your leftovers, churning out clearer water and keeping solid waste in detention. An underground tank that treats household toilet wastewater, separating solids and liquids, requiring periodic pumping.

Aerator: The unsung hero at your tap’s end, it’s like a mini tornado mixing air into your water, giving you a gentle flow and cutting down on the splashy chaos.

M&F Fitting: Plumbing’s version of a dynamic duo, it’s the one piece with a bit of an identity crisis – half macho with its male end, half gracious with its female end, coming together to keep your pipes in perfect harmony. Simply a connector with both male (external thread) and female (internal thread) ends to join pipes or fittings.

Nipple: A modest name for a vital piece — this short pipe is the connective tissue between the plumbing world’s organs, joining fixtures with the finesse of a surgical stitch.

Trap: Far from a trap in the conventional sense, this U-shaped pipe is your domestic sentinel, guarding your abode against the odorous perils of the sewer.

Backflow Prevention: The stalwart defender of your water supply, ensuring your clean water doesn’t get an unwelcome visit from its already-drained counterparts.

O-Ring: This little loop of rubber is the secret agent in your plumbing world, going undercover to make sure water only goes where it’s supposed to, being a circular gasket made of rubber or other synthetic materials used to create a watertight seal.

Ball Valve: With a simple turn, this spherical maestro can orchestrate the flow of water like a conductor with a baton.

Check Valve: The gatekeeper that ensures water doesn’t get any ideas about reversing its course, enforcing a strict ‘no return’ policy.

Plumber’s Tape (Teflon Tape): This humble white, pink, grey or yellow strip may not look like much, but it’s the seal that whispers “no leaks today” to your threaded pipe connections.

Overflow: That little spy-hole in your vanity basin playing hero, keeping your bathroom from turning into a miniature lake when you’re daydreaming with the tap left on that prevents a basin from overfilling. You can probably see one in your bathroom basin — it’s a small hole in the bowl of the basin that connects to the basin drain.

Special Mentions: Noteworthy Plumbing Essentials

P-trap & S-trap: Plumbing’s own superheroes, shaping pipes like letters to trap bad odours down below where they belong.

Bottle Trap: The sleek cousin of P and S traps, fitting snugly under your basin to keep the stink in check without cramping your style.

Water Hammer: Not a tool, but a domestic percussion you’d prefer not to hear — the alarming BANG in your pipes when water’s abruptly cut off.

Water Meter: This device ticks quietly at the boundary line of your property, dutifully recording your water usage like a silent accountant.

Bidet: The European import that’s making a splash, refreshing in a way that toilet paper just can’t match.

Waste Disposal or Garbage Disposal Unit: Your kitchen sink’s appetite for leftovers, this gadget munches on food scraps and sends them off to sewer school. Often called an InSinkErator, it grinds up food scraps for easy disposal through the sewage system, promoting environmental sustainability.

Boundary IOS: It connects your private sewer to the public one and should stand proudly at ground level, not hidden like buried treasure.

Overflow Relief Gully or ORG: A failsafe that ensures your home isn’t the next venue for an impromptu indoor pool party courtesy of a sewage overflow.

Overflow Relief Cap or ORC: The little hat for your plumbing that keeps rainwater from crashing the sewer party uninvited designed to prevent rainwater from infiltrating the sewer system via non-compliant ORGs.

Floor Waste: Not just a hole in the ground, but an escape route for water in your bathrooms and laundries, preventing indoor floods.

Cistern & Pan: The Bonnie and Clyde of toilet fixtures, one houses the water for the flush, and the other takes the hit.

Mini Stop: A miniature hero allowing you to isolate the water to your cistern should your toilet go rogue and stage a leak.

Float valve: A valve that gauges the level of water in a cistern and shuts off the flow of water when it reaches a certain capacity. This valve controls the water flow in your toilet cistern.

Bioretention Basin: Nature’s own water filter for the outdoors. It uses plants and soil to clean up stormwater runoff before it goes out on the town in the local waterways. This eco-friendly basin is a landscape hero, using layers of vegetation and specialised soil to filter pollutants from runoff water. It’s a natural filtration system that cleans water as it travels to the stormwater system, protecting our waterways with a touch of green ingenuity.

Water Efficiency Certificate: It’s like a diploma for your property, proving it’s smart with water. Get this, and you can charge tenants for their water usage, encouraging everyone to go easy on the H2O. This certificate is essential for landlords, verifying that a property is water-wise. It allows the cost of water consumption to be billed to tenants, promoting water conservation and ensuring fair distribution of water expenses.

The Safety Squad

TMV (Thermostatic Mixing Valve): This isn’t your average mixing device. It’s the unsung hero in hospitals and care centres, ensuring the water you bathe in doesn’t turn you into a lobster.

Tempering Valve: Think of this as the thermostat of your hot water system, a trusty guardian keeping the heat at a cozy 50°C and scalds at bay.

Pressure Reducing Valve (PRV) & Pressure Limiting Valve (PLV): Valves that regulate your system’s water pressure, preventing spikes and maintaining steady flow.

Sacrificial Anode: The noble warrior that takes the corrosion hit for your hot water system, ensuring the tank’s longevity.

Thermocouple: A vigilant sentinel within your hot water system, watching over the pilot light and cutting off the gas supply if it flickers out.

Duo Valve: The plumbing equivalent of a bouncer and a gatekeeper, this combo keeps your hot water flow in check and doesn’t let it backtrack. A dynamic tag-team of a two-in-one valve system featuring a stop tap to halt water flow and a non-return valve to prevent hot water backflow.

Cold Water Expansion Valve: This little gadget is like a pressure suit for your hot water system, keeping the expanding cold water from busting out as it heats up. A protective valve that prevents your hot water system from releasing hot water by managing the expansion and release of cold water as it heats up.

Relief Valve: The plumbing world’s pressure cooker whistle, it lets off steam (well, water really) from your hot water tank when things get too hot to handle. A safety mechanism on hot water systems that releases water when pressure or temperature exceeds safe levels.
