Under the kitchen sink and behind the drawers

[Townesw]

Summary: Check under your kitchen sink 
 

I walked up to an Oliver at a campground one time to introduce myself. I noticed water running down the curb side rear stabilizer. After exchanging greetings I brought the leak to the attention of the owner. After looking under the curb side bunk and finding nothing I suggested that he look under the kitchen sink for the source of the leak. Upon removal of the drawers he found water soaked plywood caused by a loose coupling on the kitchen sink drain trap. Since then I have tried to check mine occasionally to ensure that it is tight and to look around for any other problems. Today I found that the quarter turn stop on the hot water was not completely open. It had probably been like that since we took delivery. Anyway, I opened it and improved the hot water flow at the sink. 
 

Occasionally remove your (kitchen) drawers and check on stuff down there 

-tightness of the drain coupling 

-quarter turn stops fully open 

-refrigerator plug plugged in 

-hose weight located between back of drawers and rear of cabinet carcass

-hose not twisted 

-any sign of moisture 

-anything rubbing against something 

-and especially that blue clip on the faucet hose assembly. There was an owner that heard water running underneath her sink when she turned the faucet on. Turns out that blue clip was missing and the hose had completely separated.

 

We have a 2018 OEII, hull 313. Some of this stuff has probably changed. The round port was added after production to access a loose clamp on the exit end of the fresh tank overflow hose. It sure is useful for checking below the cabinets.

 

 

There is a plumbing vent under the back right corner of the range. It is supposed to let air in and not let grey tank smells out. If you are smelling something foul (grey tank odors, not black tank odors) and you can’t locate a leak you might have a bad plumbing vent.

Brilliant!

What was your motivation for adding the hatch?

As per Townesw post above.

Thanks Bill.  I had missed it by speed reading while looking at his excellent pictures.  Every one of them are perfect. 

What they highlighted to me (beyond the message of fixing the likely vent problem) is just how much dust my Ollie has between the hulls where the majority of our MEP resides.  it certainly did not come from the factory that way.  Likely the dust is from the air vents for the curb side and lots of dusty camping roads.  It can't be good for the MEP systems.

Looking forward to having to replaced the Dometic absorption refrigerator and sealing up the refer vents.  That should help on the dust issue.  Left would be the Suburban furnace grill used to provide cooling and combustion air to the furnace.  Maybe a bolder catcher filter there.   Plus about three days with a strong vacuum with 20 feet of hose.

@Geronimo John look inside the rear bumper. There is a rubber seal around the sewer pipe where it goes into the lower left rear of the trailer that will become dislocated and permit dust intrusion. Reposition the seal and place a clamp around the sewer pipe to keep the seal from slipping back out of the hole. I used a Stainless steel Banjo TC-331 just snug. Not tight.

Super easy fix.  Have added this simple DIY fix to my summer list.  "Another One Beats The Dust!"

GJ, what will be your replacement for the 3way?  Will it allow you to replace both refer vents?   I notice that the new Ollies still retain the upper vent.

 Curiosity is at work again.

I still have the outside upper vent on my 2023 with the 12V Isotherm fridge, but no more outside upper vent on the 2024s though.

..and a 2024

@rich.dev, thank you!  I had not seen photos of the 2024 model.

I like the Nova Kool R5810.  Has a larger freezer and other benefits.  Ken  (Mountain Oliver) installed one and I put together with his ideas and edits the attached DYI guide for install.  There is a good amount of info here in the forum threads as well.
