One supply, two independent outlets
Some installs need to split one incoming line to feed two fixtures — a toilet cistern and a bidet, or two appliances close together — without losing the ability to isolate each one separately. Bluegum's 2-Way 1/4 Turn Stop Valve (BLUEGUM-2WAY, $13.40) does exactly this: a single 15mm inlet splits into a 20mm and a 15mm outlet, each with its own quarter-turn shut-off, in a Tritec chrome loose-nut fitting.
Why independent shut-off on each outlet matters
Without independent isolation, servicing one fixture means shutting down both. With this valve, you can close the 15mm outlet to work on, say, a bidet connection while the 20mm outlet keeps supplying the other fixture uninterrupted — a genuine convenience on jobs where taking a whole bathroom offline isn't practical.
Loose nut fitting, quarter-turn operation
The loose-nut connection style is the common trade standard for stop valve servicing — it allows the valve to be connected and disconnected without twisting the whole fitting, which matters when space behind a toilet or vanity is tight. Quarter-turn operation means each outlet opens or closes with a confident 90-degree twist rather than multiple turns of a gate-style handle.
Typical uses
Toilet-plus-bidet combinations, a basin mixer plus a bidet spray, or any spot where two fixtures sit close enough to share a single take-off point are the natural fit. For bidet-specific fittings, see our Chrome Bidet Set guide.
Frequently Asked Questions
Can I isolate just one of the two outlets?
Yes — that's the point of the design. Each outlet has its own quarter-turn shut-off, so you can close one while the other keeps supplying water.
What sizes are the two outlets?
One outlet is 20mm and the other is 15mm, fed from a single 15mm inlet — check which outlet matches which fixture's existing connection before fitting.
What does "loose nut" mean on a stop valve?
It refers to the connection style where the nut can be loosened and the fitting removed without rotating the whole valve body — the standard trade fitting style for serviceable stop valves.
Is this valve suitable for a toilet and bidet combination?
Yes, that's a common application — one outlet feeds the cistern, the other feeds the bidet or bidet spray, each independently isolatable.
