Turner Hastings wastes and traps guide
This collection holds the Turner Hastings wastes and traps for basins and baths: a universal 32/40mm pop-up basin waste and safety pull-out bath wastes with and without an overflow. It also holds a TitanCast bath waste and adjustable brass bottle traps in S and P shapes. The sections below explain each one and how the parts work together. The questions that matter are the same for every part: does the size match the outlet, does it suit the basin or bath you have, and how does it connect to the pipe below. For the maker's wider range, see Turner Hastings.
What a waste and a trap each do
A waste is the part in the drain hole of the basin or bath. It holds the plug that closes the drain. A trap is the part below it. A trap is a curved section of pipe that holds a small amount of water, which blocks sewer gas from coming back up the pipe. The collection covers both parts: the pop-up and pull-out wastes on top, and the bottle traps beneath.
You buy them separately and they have to connect. The waste sets the thread and the tail, and the trap sets the inlet size and the outlet that joins the wall or floor pipe. Choosing both together avoids the usual mismatch.
The universal 32/40mm pop-up waste
The Turner Hastings universal pop-up waste is a two piece brass waste with a ceramic head in white, and metal heads in brushed brass, brushed nickel, chrome and matte black. It is a universal 4-in-1 that suits all basins with a 40 or 32mm waste outlet, with or without an overflow. It is Watermark approved to Australian standards and suitable for baths. It has a solid brass body and spring construction.
The body is brass, and the white version has a gloss white real ceramic head. A plug and waste that suits both sizes and both overflow arrangements removes the usual guesswork about which version to order. For other universal wastes and the size rules, see pop up basin wastes.
Fitting the universal waste
The installation steps are short. Locate the silicone washer in the recess on the top face of the waste body, and make sure it contacts the mounting surface. The hole in the basin needs to be between 43mm and 48mm. From below, push the waste assembly up under the hole and hold it in place. Apply silicone with a silicone gun to make a watertight seal, so that the waste holds water. Slide the flange washer over the tail of the waste flange and locate the assembly in the waste hole.
The hole size is the figure to check first. A basin with a hole outside 43 to 48mm needs a different waste. If you are not comfortable with the plumbing below the basin, a licensed plumber can fit the waste and check the connection to the trap.
Safety pull-out bath wastes
The safety pull-out bath wastes are made for family bathrooms. The pull-out feature is made with children's safety in mind and an extra strong mechanism prevents accidental unplugging. A large gap gives a high flow rate so the bath empties quickly, and a solid brass body lets the mechanism be exchanged without removing the bathtub.
The brushed brass and matte white versions have a unique removable cartridge for servicing and cleaning, a 40mm size without overflow, and Watermark approval to Australian standards. They are one of the only bath tub approved pop-up wastes on the Australian market. For other bath wastes, see pop up bath wastes.
Short tail, 50mm tail and overflow versions
The bath wastes come in several arrangements. The brushed brass version is a 40mm safety pull-out pop-up bath waste with a short tail. The version with overflow suits baths with an internal overflow, with a surface diameter of 70mm, a height and width of 50mm, a depth of 80mm and a G1 1/2 thread.
Versions without an overflow suit baths that have none, and the ceramic head versions in matte white and gloss white are non-overflow. The match with your bath is the thing to confirm. For wastes designed for baths with an overflow connection, see bath wastes with overflows.
The clear channel and the removable cartridge
Two features stand out in the bath wastes. A clear channel design lets a plumber service the drainage pipe without obstruction, and a removable cartridge allows servicing and cleaning. Hair and soap collect at a bath waste, and a part that comes out makes the job simpler.
The TitanCast version has a clear channel that serves the same purpose, with no obstruction when a plumber services the drain if there are any issues.
The TitanCast bath waste
The TitanCast 40mm safety pull-out bath waste is a different build. It has a TitanCast solid surface top on a chrome on brass base, in satin silk white and gloss white. It is non-overflow only. The top diameter is 70mm, the waste length is 50mm, the thread is G1 1/2 inch and the required hole size is 40mm, and it is not compatible with an overflow.
It comes in an array of colours. Check the colour you want and confirm that your bath has no overflow before you order.
Basin sizes: 32mm and 40mm
Two outlet sizes dominate basins. The size 32mm is the most common basin outlet size, and a qualified plumber should confirm it. Basins are usually 32mm and baths usually 40mm, so measure the outlet at the part inside the basin. A 32mm waste can connect to 40mm pipework with an adaptor.
The universal Turner Hastings waste is sold to cover both, which is the reason it is called a 4-in-1. The other waste families have a G1 1/2 thread, which goes with the 40mm size. The traps follow the same logic: the universal 32/40mm inlet takes either outlet, and the 40mm outlet joins the pipe.
With or without an overflow
An overflow is a small hole near the rim of a basin or the top of a bath. A basin or bath with an overflow needs a slotted waste, which drains overflow water whether the waste is open or closed. One without needs an unslotted waste, which is watertight when closed. A mismatch can cause leaks or stop the overflow working, with the risk of floods.
The universal basin waste suits use with or without an overflow, so it avoids that choice. The bath wastes are the opposite: there is an overflow version and a non-overflow version, so match the bath. If you cannot tell which your bath has, look for the hole in the bath wall near the top.
Bath size and the pipe below
Bath wastes are 40mm. The 40mm figure is the internal diameter of the pipe the waste connects to, and a 40mm waste uses a 1 1/2 inch BSPP thread. A bath connects through a waste of at least DN40, either as an untrapped waste to a floor waste gully or through a trap, so a 40mm bath waste matches that pipe size.
The Turner Hastings bath wastes have a G1 1/2 thread, which matches the 40mm bath size. The tail length matters as well. Check the clearance under the bath against the length of the waste tail, which is why the short tail versions exist.
Bottle traps
A bottle trap gets its name from its shape. It sits under the basin, in view or hidden, and the water held in the bend forms a seal. Each use pushes older water along, and the trap catches debris that gets past the waste. Bottle traps suit exposed pipework, P-traps suit concealed plumbing, and S-traps suit floor outlets.
The Turner Hastings bottle trap replaces the plastic trap with something more visually appealing, and it is a statement piece in its own right. The S trap hides the plumbing under a wall hung basin with a floor length bottle trap.
Finishes and how they are made
The finishes include chrome, brushed brass, brushed nickel, matte black, gloss white, matte white and satin silk white. The brushed brass bath waste is an ultra-durable PVD finish, and the S trap has a PVD brushed brass finish. The ceramic versions use a real ceramic head.
For the other finishes, check the finish process on the product, and use the colour name to match your tapware.
Care and cleaning
Bottle traps need regular cleaning because debris collects in the base. Clean trap bodies every three to six months and avoid caustic cleaners. Bottle traps have a removable base cap for the job.
To clear a bottle trap, put a bucket under it, unscrew the base cap by hand, tip out the hair and soap, rinse the cap and thread, and refit it hand tight. Run the tap and check the joint for drips before you close the cabinet.
For the wastes, lift out the cartridge where the instructions say it comes out, rinse it and refit it. Wipe the finish with a soft cloth and mild soap, and avoid abrasives. Hard water scale can stop a seal working, so wipe the plug dry if your water is hard.
Matching to the rest of the Turner Hastings range
The kitchen sink wastes are collected at Turner Hastings basket wastes, and bottle traps from every maker are at bottle traps. A matching finish is a visual choice and does not change the fit.
For the basin wastes across all makers, see basin wastes.
How to choose
Start with the fixture. A basin takes the universal 32/40mm pop-up waste if its hole is between 43mm and 48mm. A bath takes a safety pull-out waste, in the overflow or non-overflow version that matches the bath. Then choose the trap that fits the pipe: a bottle P or S trap, with a 32/40mm inlet and a 40mm outlet.
After that the choice is the finish and the cleaning. A removable cartridge is the easiest to clear, and a visible trap deserves the finish that matches your tapware. If you are unsure about any connection, a licensed plumber can confirm the fit before you order.
