Pressure leak in the front left

Bbaldwin

hello,

I have a 2016 T@B S, with the bathroom/shower. I have a leak somewhere in the left front of the trailer, it’s I not the pump. I can see the pump through the access door above the toilet but not behind the wall its mounted too. Pretty sure the leak was caused by pressure, I was filling the tank to check it and I got distracted and left the hose running in the filler much longer than I should have.

the nearest nucamp dealer is roughly 100 miles away so I took the T@B to a local shop, been in business a long time well regarded, but they’ve never worked on a T@B before. He agrees that it’s a pressure leak somewhere in the left front of the trailer, but neither he or I can figure out how to access the plumbing in that area, short of pulling the shower/toilet out or removing the diamond plate on the front of the trailer, or removing the sink/cabinent. Can anyone here tell me the best way to access that section of plumbing?

When did you notice the leak? Was it immediately after filling the tank? Or was it after you activated the pump to draw water from the tank?

Under normal circumstances, filling the fresh water tank on a 2016 does not involve pressurizing anything. The tank fills by gravity, and air is displaced through a vent above the fill port. So, while you might have made a big puddle on the ground, it's unlikely you would have damaged anything by leaving the hose running a little too long.

no, I’ve drained it and refilled it acouple of times, it definitely has a leak. When I turn the pump on water starts to drip out of bottom of the trailer

Ok. Check this first…

Stick your arm down in the hatch (it takes a little T@B yoga) and see if you can reach the back of the city water fill port. It's a screw-on connector that tends to loosen over time and cause a leak in that area when the lines are pressured.

Please report back after. If the leak persists we'll dig a little deeper!

thanks, I’ll try it, might be a day or two, the trailers still at the RV shop in chico

And if that's not the culprit, it is possible to build an access hatch to get to the area behind the toilet wall.

It may take some more of that T@B yoga,, but try to locate the leak before breaking out the demo tools. Ripping out the entire shower us almost certainly not necessary!
