The Combination Trap That Stops You Fighting Under the Sink
Every plumber knows the job. You're on your knees under a laundry tub or kitchen sink, trying to line up the washing machine waste and the dishwasher connection to a standard combo trap, and nothing sits right. You add an elbow. Now it fouls something else. You remake the joint. Now the nipple's pointing the wrong direction again.
It's a five-minute job that eats thirty minutes because the fitting won't cooperate.
The Twister Combination Trap was designed specifically to end that problem — and it does.
What Makes the Twister Different
Standard combination traps have fixed nipples. Whatever angle they come out of the factory is the angle you get. If that angle doesn't suit your installation, you're adding elbows, cutting offsets, or remaking joints until something fits.
The Twister has two nipples that rotate a full 360°. You twist them by hand to whatever position suits the job — before or after the trap is in place — and they stay where you put them. No tools. No additional fittings. No second attempt.
That's the whole fix. But if you've ever spent 20 minutes under a kitchen sink solving what should be a two-fitting problem, you understand exactly how valuable it is. The design is patent-pending, and it's not hard to see why — it's one of those ideas that makes you wonder why it didn't exist ten years ago.
Two Traps in One Unit
The Twister also converts between two configurations without any extra parts. Out of the box it works as a full-height combination trap. Remove the extension piece and it becomes a low-level combo trap. One unit on the van covers both situations.
That's a stock reduction and a call-back risk reduction in the same fitting. Available in 40mm (DOVMC40) and 50mm (DOVMC50) to suit standard basin, sink, and laundry waste applications.
The Compression Unions Matter
It's worth calling these out separately. Compression unions throughout mean the trap is straightforward to pull apart and service down the track without cutting into the line. For rental stock or commercial installs that'll be accessed again, that counts. You're not installing a problem for future you.
Who This Is Built For
If you run a fit-out business, service residential plumbing, or do a volume of laundry and kitchen connections, the Twister is the kind of fitting that pays for itself in time savings on the first job it goes on.
At $9.40 for the 40mm (DOVMC40) and $9.90 for the 50mm (DOVMC50), there's no reason to stock anything else.
