Two Way Tap and Wall Bib Tap: Where Each Belongs

 

1. Introduction: the tap nobody specifies

Quick Answer: A bib tap is a simple wall-mounted tap with a threaded outlet for a hose. A two way tap is the same thing with two outlets from one inlet, so two appliances or hoses can share one supply point.

Every renovation specifies the basin mixer down to its finish, and nobody says a word about the bib tap in the yard.

That tap does more work than most of the fittings inside the house. It fills the washing machine, feeds the hose for the car and the plants, rinses the wet kitchen floor, fills pails during a supply cut, and takes whatever the mains pressure happens to be that day with no mixer or valve softening it.

It also fails in ways the indoor fittings do not, precisely because of that. Hoses stay screwed on for years under pressure. Handles get slammed shut with wet hands. Sun and rain work on the finish. And because it is outside or in a service area, nobody notices a weep until the wall is stained.

This guide separates the tap types, explains what a two way tap is actually for, covers the problems specific to this class of fitting, and finishes with what to check when buying. The video below shows one being fitted to an external wall.

2. The family, sorted by what it does

Quick Answer: Bib tap for a hose, pillar tap for a basin or sink deck, wall tap for a fitting without a deck hole, two way tap where one point serves two things. Same water, different jobs.

These names get used interchangeably in conversation and they are not the same product.

Simple tap types used in Malaysian homes, where each mounts, what it connects to and the job it is designed for.

Type	Mounts	Outlet	Made for
Wall bib tap	Wall	Threaded, for a hose	Yard, washing machine, pails
Two way tap	Wall	Two, each with a handle	One point serving two things
Pillar tap	Deck or counter	Open spout	Basins and sinks with a hole
Wall sink tap	Wall	Open spout, longer reach	Counters with no tap hole
Two way tap with bidet holder	Wall	Two, one for a spray	Wet areas with a spray hose
Two way angle valve	Wall, under a fitting	Two, isolating only	Splitting a supply, not dispensing

Compiled reference for simple tap types available in Malaysia, September 2026.

The last two rows are the ones people confuse, and the distinction is worth holding onto. A two way tap dispenses water you turn it on and water comes out of an outlet. A two way angle valve only splits and isolates a supply; it feeds two fittings that have their own controls. They look similar, they sit in the same part of a wall, and using one where the other belongs is a common mistake. The valve version is covered in the angle valve guide.

Row five is a genuinely local product. A two way tap with an integrated bidet holder appears in the local taps and fittings range in stainless steel, because a spray hose beside a wall tap is such a normal arrangement here in a wet kitchen, a laundry area or an outdoor washing point.

3. Where a bib tap earns its keep

Quick Answer: Washing machine feed, yard hose, car wash point, wet kitchen, pail filling and floor rinsing. In most Malaysian homes one tap is doing several of these jobs, which is exactly when a two way version pays for itself.

Map what the tap actually serves before deciding what to fit.

Positions where bib taps are fitted in Malaysian homes, what each typically serves, whether a hose stays connected and whether a two way tap is worth fitting there.

Position	Serves	Hose left on?	Two way worth it?
Laundry area	Washing machine	Always	Yes, so the point stays usable
Wet kitchen	Floor rinsing, pails	Often	Yes, hose plus open outlet
Front porch or car park	Car washing	Sometimes	Useful, not essential
Rear yard	Plants, general use	Usually	Useful
Bathroom, low on the wall	Pail filling, floor washing	Rarely	Only with a spray
Balcony or drying area	Cleaning, occasional use	No	No

Compiled placement reference for bib taps in Malaysian homes. Positions vary considerably between landed and high-rise properties.

Row one is the single most useful line here. A washing machine hose screwed permanently onto the only bib tap in the laundry area means that tap is unavailable for anything else so people unscrew the machine hose to fill a pail, forget to reconnect it properly, and end up with a leak behind the machine. A two way tap gives the machine a permanent outlet and leaves a second one free, and it is a cheaper fix than any of the alternatives.

Row two describes the wet kitchen, where the arrangement often wants a hose for the floor and an open outlet for a pail at the same time. Again, a two way tap rather than a splitter that has to be unscrewed.

4. The problems specific to this tap

Quick Answer: Banging pipes from taps being shut too fast, hoses splitting because they sit pressurised for months, finishes failing in sun and rain, and wall threads leaking because the tap gets pulled sideways by the hose.

These faults barely occur on indoor fittings and are routine on this one.

Problems specific to bib taps and outdoor taps in Malaysian homes, the actual cause of each and the practical prevention.

Problem	Cause	Prevention
Pipes bang when it shuts	Quarter-turn shut, moving water stops hard	Close it gradually
Hose splits near the tap	Left connected and pressurised	Shut the tap when not in use
Weep at the wall thread	Hose pulling the tap sideways	Support the hose, do not hang it
Finish blistering or peeling	Sun and rain on plated zinc	Brass or stainless outdoors
Handle seizes	Rarely used, spindle dries out	Operate it occasionally
Drips constantly	Washer hardened, grit on the seat	New washer, a few minutes' work

Compiled fault reference for bib taps and outdoor taps in Malaysian conditions.

Row one explains the bang that people assume is a fault in the pipework. Water moving through a pipe has momentum; close a tap suddenly and that moving column stops against a closed valve, and the shock travels back through the system. Bib taps produce it more than any other tap because they run at full flow and get shut in one movement. Closing gradually costs a second and removes the noise entirely.

Row two is the one that causes actual damage. A hose left screwed on with the tap open sits at full mains pressure day and night, and the weakest point usually the collar at the tap end eventually gives. Shutting the tap between uses costs nothing and roughly doubles hose life.

Row four matters outdoors specifically. A plated zinc tap in direct sun and tropical rain will blister within a couple of years, while brass or stainless will not. Outside is the position where the base material matters most, for the same reason it matters in a bidet spray the finish is only a few microns thick.

5. Position and height

Quick Answer: High enough to get a pail under it, low enough to reach comfortably, and far enough off the wall that a hose connector can be screwed on without scraping knuckles. Those three requirements conflict, so choose deliberately.

Bib taps are frequently fitted at whatever height the pipe happened to arrive, and it shows.

The pail test is the useful one. A tap fitted too low means every pail has to be tilted under it or filled on the floor, which is the difference between a convenient washing point and one people avoid. Stand the largest pail you use against the wall and put the tap above it with room to spare.

Standoff from the wall is the second consideration and the most often ignored. A hose connector needs to be gripped and turned, and a tap sitting flat against the wall leaves nowhere for fingers. A short extension piece solves it if the tap is already fitted.

Then think about what happens to the water. A bib tap over a floor with no gully means splash across the whole area, and in a wet kitchen or laundry that water has to go somewhere. Ideally the tap sits over or beside a floor drain.

Finally, height and position interact with the hose. A tap positioned so the hose has to bend sharply as it leaves the outlet puts the same repeated stress on the hose collar that splits it. Give the hose a gentle curve rather than a right angle the same principle that governs a bidet spray hose.

6. Choosing one

Quick Answer: Brass or stainless body, a threaded outlet that matches your hose connector, one or two outlets depending on what the point serves, and a handle you can turn with wet hands.

The list is short because the fitting is simple.

Checks to make before buying a bib tap or two way tap, what each determines and the mistake it prevents.

Check	Determines	Prevents
Body material	Life outdoors	A blistered tap in two years
Outlet thread	Whether your hose fits	Needing an adaptor
One outlet or two	Whether it serves two things	Unscrewing hoses constantly
Inlet thread size	Whether it fits the wall point	A tap that will not screw on
Handle shape	Grip with wet, soapy hands	Forcing it with pliers
Whether it is serviceable	If a washer can be changed	Replacing it when it drips

Compiled pre-purchase checklist for bib taps and two way taps in Malaysian homes.

Row six is the quiet one. Many inexpensive bib taps are sealed units where the headwork cannot be removed, so a dripping tap becomes a replacement tap. A serviceable one takes a generic washer and can be repaired in five minutes for the price of a coffee the difference explained in the dripping tap guide.

Row five is not a small point on this tap in particular. A bib tap is turned by people with wet hands, sometimes with soap or detergent on them, often in a hurry. A knurled or lever handle is turned easily; a smooth round one is not, and a smooth round handle that has stiffened is what gets attacked with pliers.

7. Conclusion: the hardest-working tap in the house

A bib tap is worth thirty seconds of thought, which is roughly thirty seconds more than it usually gets.

Work out what the point actually serves. If a washing machine hose lives on it permanently, fit a two way tap so the second outlet stays available and nobody has to unscrew anything. If it is a wet kitchen point that needs a hose and a pail at the same time, the same answer applies.

Buy brass or stainless if it lives outdoors, because a plated zinc body in tropical sun and rain will look poor within two years. Check that the washer can be changed, so a future drip is a five-minute repair rather than a new tap.

And then teach the household two habits: close it gradually, and shut it between uses. The first stops the pipes banging, the second roughly doubles the life of every hose in the house. Neither costs anything, and together they prevent most of what goes wrong with this fitting along with keeping the isolating valve that feeds it working, so the eventual repair stays a small one.

8. Frequently asked questions

What is a two way tap?

A wall tap with one inlet and two separately controlled outlets. It lets one supply point serve two things at once typically a washing machine hose on one outlet and a free outlet for a pail or garden hose on the other.

What is the difference between a two way tap and a two way angle valve?

A two way tap dispenses water when you open it. A two way angle valve only splits and isolates a supply feeding two fittings that have their own controls, such as a cistern and a bidet spray.

Why do my pipes bang when I turn off the outside tap?

Water moving through the pipe stops abruptly against the closing valve and the shock travels back through the system. Bib taps cause it most because they run at full flow. Closing the tap gradually stops it.

Should I leave the hose connected to the tap?

Connected is fine; pressurised is not. Leaving the tap open means the hose sits at full mains pressure day and night, and the collar at the tap end eventually splits. Shut the tap between uses.

What material should an outdoor tap be?

Brass or stainless steel. Plated zinc alloy blisters and peels in tropical sun and rain within a couple of years, because the plating is only a few microns thick and the metal underneath does not tolerate the exposure.

Can a bib tap be repaired when it drips?

Most can, with a generic washer, in a few minutes. Some inexpensive ones are sealed units that cannot be opened, so ask whether the headwork is removable before buying.
