Leaking gray tank 2014 hurricane

[GDTRFF]

I have a slow drip leaking into the bay where my dump valve is. It’s a steady, slow drip. I’ve tried to chase the leak under the rv but the pipes disappear and I can’t see where it’s coming from. Any ideas on how to locate and fix this problem?
It’s a 2014 hurricane

Which model Hurricane? My drip was a busted shower drain pipe.

How did you find your leak?

The far drivers side rear storage compartment seemed to have water in the bottom after each trip. I originally thought it was a bad drain plug. Allowing water to enter when driving in the rain. While at a KOA this past June, it was wet again. No rain. I dried that bay and checked it after taking a shower. Sure enough, water. Not a lot. That bay is directly beneath the shower. I had read a previous thread on this forum about the soft shower floor movement causing the rigid pipe the break. So I took that panel off to expose the shower drain, yep, water, Broken pipe. Most water was still going down to tank. But some was seeping out and dripping into the bay. After 2 trips to Ace Hardware and the loss of some skin on my knuckles, I replaced that section with a piece of rubber pipe and 2 hose clamps. The drain pipe now flexes with floor movement. I hope this is your issue.

Thanks

Contact Thor Customer Service and ask for a drawing of the waste water system, and the fresh water system. Call, don't email them, they don't seem to answer emails too well.


FYI, the kitchen sink and the shower are the only things that drain into the gray tank. The Bathroom sink and toilet empty into the black tank.



Are you sure the drip is actually water from the gray tank and not a fresh water line leak? I think there are several fresh water lines in the coach that service the shower, bath sink, and toilet if leaking could show up where you are seeing the drip. Good luck

Problem solved!
I replaced the rigid connectors under the rig leading to the flush out valve. Then noticed a crack in the last two foot of pvc. Removed and replaced that. Connected everything with rubber connectors and hose clamps. It’s dry now. I’ll be driving tomorrow. If that fix did t work I’ll post again. For now. Thanks for everyone’s help.
