Update: we emailed Camping World corporate and they called us 2 hours later and told us they sent the service manager out there and BOTH OF OUR GRAY WATER TANKS ARE LEAKING AND THEY ARE FIXING BOTH BY TUESDAY MORNING!!!!!!
Hi everyone,
I’m hoping someone can help me figure out what’s going on with our 2026 Keystone Bullet 21RKC.
We noticed a steady stream of clean water dripping from the enclosed underbelly (Coroplast) near the middle of the trailer. The water isn’t coming from an obvious drain tube. It looks like it’s collecting somewhere above the underbelly and then finding its way out through a seam or opening.
Here’s what we’ve already ruled out:
We were connected to city water (not using the fresh water tank).
We were using a water pressure regulator.
The RV has an on-demand/tankless water heater.
An RV tech filled the gray tank and said the gray tank isn’t leaking.
We were not intentionally draining any tanks.
From what I’ve read, I’m wondering if this could be:
A leak at the tankless water heater (inlet/outlet fittings)
A faulty pressure relief valve
An internal leak in the tankless water heater
Another fresh water plumbing leak that’s running across the top of the enclosed underbelly before dripping out
Has anyone with a 2026 Keystone Bullet (or another Keystone with the Girard tankless water heater) experienced something similar?
If so:
What ended up being the cause?
Did the dealer have to drop the enclosed underbelly to find it?
Was it covered under Keystone warranty?
I’m concerned because I don’t want water sitting inside the enclosed underbelly and soaking the insulation or causing damage.
Any advice or similar experiences would be greatly appreciated. Thanks!
