The only RV waste valve designed to be installed once and serviced indefinitely. Built in North America since 1964.

A waste valve built to outlast your RV

Most RV waste valves are designed to fail. Thin plastic bodies, non-replaceable seals, blades that gunk up, handles that snap off. The standard-issue blade gate valve installed on virtually every RV on the road is built to an OEM price point of just a few dollars per unit, and every cost-down decision ends up in the part of your plumbing system handling the most aggressive flow.

The Dupree Twis-Loc is the opposite of that. Heavy-duty ABS body. Positive-lock handle. Fully serviceable internals. The same valve has been in continuous production since 1964 — and we have units from that decade still operating in their original installations.

What makes it different

Heavy-duty ABS body. Significantly thicker than the typical RV gate valve. Designed for the structural loads of slip-joint flex, road vibration, and freeze-thaw cycles that crack thin-wall valves.

Positive-lock handle. A half-turn opens or closes the valve, and the handle locks into the closed position. No slipping under road vibration. No accidental bumps opening the valve while you connect your sewer hose. When the Twis-Loc is closed, it stays closed.

Two-screw serviceable internals. When a seal eventually wears, two screws and a replacement kit restore the valve to factory condition in a couple of minutes. You don't replace the whole valve. You don't disturb the slip-joint gaskets. You service the valve and put it back to work.

60+ years of field validation. Specified by SilverStreak travel trailers and Blue Bird Wanderlodge motor coaches at the height of their premium reputations, and chosen today by high-end motor coach manufacturers. The valve in use on a coach built in 1968 is the same design — refined but architecturally identical — that ships out of our facility this week.

Built in North America. Valve bodies precision-molded in Canada. Final assembly at our facility in the United States. Same manufacturing footprint since 1964. Email us with a question and the response comes from the people who actually make the valve — not a customer service queue.

Fit and installation

The Twis-Loc installs as a permanent part of your waste plumbing system. The 3-inch standard size fits any motorhome, fifth wheel, travel trailer, toy hauler, or motor coach — but the install is more involved than a bolt-on valve swap. It's best suited for new builds, major renovations, or professional retrofits.

When you're done replacing valves

The case for the Twis-Loc is simple. It's a valve you install once and maintain indefinitely. The serviceable design means you're buying into a product, not a consumable. The 60-year track record means you're not the experiment. The North American manufacturing means the people who make the valve are the same people who answer your email.

If your valve has failed or is failing, this is the upgrade that ends the cycle.

A Match Made in Heaven
Format: Hardcover
Marjorie Woollacott has provided the world with an incredible opportunity. The opportunity of merging two parallel universes; the scientific exploration of the brain, mind, consciousness, and awareness with the inner journey of one’s spiritual path of yoga and meditation. Marjorie has had her feet firmly walking the path of science and meditation for over 40 years. She gives her readers what they have been wanting for decades which is a readable resource to understand the complex scientific research of neuroscience and to understand the ancient texts of yoga and meditation. She eloquently explains to the readers how these two worlds were so far apart, and are now communicating and working together to solve the glorious mysteries of the mind, the brain and meditation. This is a match made in heaven. Deep exploration of the mental and spiritual bodies allow the readers to revel in these mysteries and begin to appreciate the unlimited vastness of a human birth. I loved this book and bought the Kindle version, but now realize this is a book I need to have in print so I can easily revisit sections which are worth future contemplation.

An award-winning book exploring the relationship of science and spirituality
Format: Hardcover
This highly engaging, award-winning book is the best introduction for non-specialists that I’ve come across that offers an intelligent alternative to the existential meaningless implicit in the materialist paradigm. Woollacott, a recently retired neuroscientist, takes readers on her quest to reconcile the objective world of her scientific study with the meditation experiences of her personal life. For most of her career, Woollacott kept her subjective experiences separated from scientific work. Having now retired from active scientific research, she now explains in this book how she came to construct a coherent worldview which synthesizes quantum physics, Hindu philosophy, and her own meditation practice. Having read numerous books in this genre, I most appreciated her intelligent exposition of scientific studies for the non-specialist, explaining how she came to favor panpsychism over materialism, all framed within her own life-long journey towards answering life’s biggest questions. I will gladly return to this book frequently as I try to help students consider an alternative to the materialist paradigm.

An Indispensable Guide to the Scientific Argument about the Primacy of Consciousness throughout the Universe!
Format: Hardcover
I couldn't put down this book! It's a fascinating account of one scientist's personal and professional journey to the heart of the mind/brain problem: which is primary? Marjorie Woollacott's account of her own scholarly research and her attempts to integrate her profound experiences of perfect awareness through the path of meditation is a tale for our times. She clearly shows the deficiencies of the current scientific model that postulates that awareness is only a function of brain activity, but more than that she integrates modern physics, in the form of quantum mechanics, with the ancient wisdom of the seers of her chosen spiritual tradition, Kashmir Shaivism, and voila! shows them to be identical in essence, if not in expression. As more people pursue meditation practice as a way to generate deep insights into consciousness, Dr. Woollacott's book is an indispensable guide to the contemporary scientific discussion around these issues. The case studies are moving and her personal journey is just as bold as her scientific work must be. This is "the book of a lifetime" for her, the culmination of years of research, study and contemplation. Bravo!

Format: Hardcover
Ms. Woollacott has done an amazing job of beginning to document the nature of the conscious substrate that forms the very foundation of our existence, and she does so in a scientifically responsible fashion. An endeavor of this nature by a professional scientist takes not a small amount of courage because this is a topic that is ignored and often ridiculed by many mainstream scientists. The fact that we have attained a large body of evidence that points ineluctably to the reality of non-corporeal consciousness in the universe is enough to warrant serious investigations into this phenomenon, and hopefully this erudite work and others like it will spur further scholarly investigations into this subject of overarching importance. As an added bonus this book is a thoroughly enjoyable and stimulating read; it's hard to put down once you start reading. This is must read for all people who are curious about the ultimate nature of their being, and by all rights that should include everyone.
