Sunmixer Deck Mounted Faucet with 2 side-handles T20138

The Sunmixer T20138 is a deck-mounted commercial faucet with two side handles, carrying a WELS 4-star water efficiency rating and Watermark certification — the latter being what allows an Australian plumber to install it under the Plumbing Code. Two side handles means separate hot and cold control rather than a single mixer lever, which is the traditional arrangement and the one many kitchens still specify.

Why operators choose the T20138

• Two side handles - separate hot and cold — a traditional twin-handle arrangement rather than a single mixer lever. Some operators prefer it: each side is independently serviceable, and there is no cartridge to fail
• WELS 4-star water efficiency — measured and comparable rather than a claim. On a tap that runs through every service the star rating is the water bill
• Watermark certified — the certification that decides whether your plumber can legally install it. An uncertified import can fail inspection and hold up a fit-out sign-off
• Deck-mounted — mounts through the bench or sink deck, so it suits an island or prep bench with no wall behind it
• Hot and cold connection — a genuine mixing tap rather than a cold-only outlet
• Certified product sticker supplied — the physical evidence an inspector may ask for

Specifications

Venue suitability

The T20138 suits commercial kitchens, prep areas and pot-wash sinks where a twin-handle tap is preferred or specified. Sitting between the 3-star mini pre-rinse unit and the 5-star wrist-action faucet in the same Sunmixer range, it is the middle option on water efficiency.

Installation & delivery

This is a plumbing fixture, so have it installed by a licensed plumber — Watermark certification only protects you if the installation complies too. It is deck-mounted, so you need holes through the bench or sink deck and access beneath for hot and cold connections. A twin-handle tap needs a wider mounting pattern than a single mixer, so check the deck layout before drilling. Our recorded packed dimensions for this model are incomplete — see the FAQ — so ask our team if you need them for freight.

Frequently asked questions

Q: Why choose two handles over a single mixer lever?

Serviceability and preference. With separate hot and cold handles each side is independently repairable and there is no mixing cartridge to fail. A single lever is quicker to operate one-handed. Neither is better; twin-handle is often what an existing bench layout or a specification calls for.

Q: What does WELS 4-star mean?

It is a measured position on the Australian Water Efficiency Labelling and Standards scale. For reference across this Sunmixer range: the mini pre-rinse unit is 3-star, this faucet is 4-star and the wrist-action faucet is 5-star. On a tap running all day that difference shows up in the water bill.

Q: Why does Watermark certification matter?

It certifies the product for Australian plumbing installations under the Plumbing Code of Australia. A plumber can install a Watermark-certified fitting without a compliance problem; an uncertified one can fail inspection, which in a commercial kitchen can delay your final sign-off.

Q: What are the packed dimensions?

Our data records them as 350 x 490 x 39 mm, and that 39 mm cannot be right on a product 390 mm tall - it is a missing digit. We have flagged it and left it out rather than publish a figure we know is wrong, or reconstruct one. Ask our team if you need freight dimensions.

Q: Can I connect it to hot water?

Yes - it takes both hot and cold, with a separate handle for each.

Q: What warranty does the T20138 come with?

Covered for 2 years parts only — labour is not included, so allow for a technician's time in your own budgeting. Terms vary by product — see our warranty information page for full details.
