Dupree sewer hose connection leak. - rheavn - 04-06-2018

This is a common problem that has been "fixed" using different materials. I give Ashley Pardue credit for finding an o ring that has resulted in both his and my sewer connection not leaking a drop.

You can source the o rings at:

McMaster Carr-Part #9396k227

or

Amazon--https://www.amazon.com/gp/product/B000FN1132/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Installation tip: Coat the o ring with silicon grease and stick it on the stationary side of the Dupree sewer connection. Bring the hose side up and tighten lock ring. Lock ring is a little hard on the first connection.

I will report back on the durability of the o ring.

Hope this helps someone............................

If it does not drip, it will help me! Ordering today.

Can I assume there is no gasket on the hose side connector?
Thanks Mike

Nothing on the hose side connector.

I added the o-ring as well, but on the hose end. I set the o-ring in a bed of silicon and attached the hose with only a partial turn of the locking collar while the silicon "set" leaving some compression of the ring to seal with a full turn of the ring. It has sealed without leaks since last spring.

If I had to do it again, I would follow Steve's approach.

Note that the Amazon url gets you a unit of 10.

During our travels in "The Rolling R Ranch" we met another Newell owner who gave me a suggestion which fixed the sewer hose leak problem. Before implementing his solution, I carried a supply of Dupree foam rings - at least 6 to 10 of them. Would change them out as needed, but the new one never lasted very long. His suggestion: Do not remove the old ring, just apply another one directly to the old one. When it leaks again, apply another. This works great! I think after the third ring I never had another problem for the remaining three years we traveled in the Newell. I am certain when we sold our coach I had/gave the new owner my supply of foam rings - don't recall it I explained the proceed to him. (Sorry, Paul.)

I recently replaced both Dupree valves with no problem. When I bought a new discharge hose I found the connections were a different style. It seems I heard of a conversion to the new style hose but can find no information on it. Any information would be appreciated

Many of us have created our own Dupree to Valterra conversion solutions.
