2 leaking sink trap valves

[RussMcKnight]

Travelswithollie Hull #125 delivered March1st 2016. Started dripping out of forward drains under trailer. Discovered that kitchen sink trap was leaking through threaded fitting. Replaced trap with new PVC with clean-out plug and not threaded. Underside leaking continued. Discovered bathroom trap was also leaking!!!

this trap looks impossible to replace/repair where it is. 
1.  Why in the world was threaded pipe used?  Leaks are through the “glued” threaded fittings. 
2.  Can anyone tell me how to repair/replace without tearing out the shower floor?

 

I have a photo of the Replaced trap.

It can  be repaired without any major renovations.  You won't have to remove the shower pan.  You'll need a special spanner wrench to reach into the drain and hold the chrome piece stationary while unscrewing the fitting from the dinette access panel outside the bathroom wall.  You will need to either grow and extra 8 foot arm or get someone to help with this. This job is so much easier on the Elite II's than the old Elites due to the fact that the shower pan is now raised above the coach floor.  It's still not easy, but it can be done.  Good luck!

I am not positive if there is a rubber gasket under the drain.  That might be your leak. I would be really interested in seeing pictures of this entire repair. Good luck.

Here's what I removed under the kitchen sink with arrow to leak point. The shower trap appears to be leaking from the exact same spot.  My only access is through the dinette seat. We don't have an access panel.

RussMcKnight -  Did you have success with your repair? Mind to share your final solution/fix?

Thank you,

Just discovered I have a similar leak at the lower threaded fitting below the shower on the downstream side of the p trap.  Any update on how to proceed?   Called Oliver and they indicated they can't really help me source new PVC pieces so I can fix myself.  The larger PVC is for the black tank drain that inserts into the black tank.   Has an o-ring section that appears was broken due to over tightening during the build.  Not really an issue for us as we have compost and do not use the black tank for anything.  Would like to replace with new if I could find the PVC piece and rebuild to it would be as good as new.   

As for the p trap, not sure if it is leaking at the lower fitting or has a hairline crack somewhere.  The hard to find piece is the connector that attaches to the shower drain.   Any advise would be greatly appreciated.   

Will head to a larger hardware store (Lowes and/or Home Depot) to see what I can find to rebuild.

Happy to report I was able to source a new gasket for the connection between the Shower drain and the ABS piping.  It is called a "Coupling Washer 1-3/4" OD 1-3/8" ID" and can be purchased at a local hardware store for less than 2 bucks.  Upon replacing the coupling washer and reinstalling the p trap with a little bit of pipe dope on the lower connection, I am happy to report it no longer leaks.   

BTW:  I did have to remove the 3" Black Tank connection to provide me with enough room to get the p trap out and back.  Also recommend you get a small strap wrench to loosen and tighten the drain p trap as it is really hard to reach and twist.   

In case anyone else find that they need the adaptor fitting that goes into the poly black tank, I was able to cross reference a partial part number and come up with the name as an ICON Technologies Limited Model # 12511 Holding Tank Fitting 3" Hub Fitting.  It is available on Amazon for less than $10 or on camping world's website for around $5.   

 

Also note that Oliver service indicated that they have changed this drain design several times since 2017, so your setup might be much different and require other parts.
