Fresh Water Holding Tank - Leak From Underbelly Pipe

[BoardBabe]

I have a 2005 189FBR Fun Finder! We are fairly new to this camper and are still learning some ins and outs. As I was flushing out the tanks/pipes from winterization, we noticed that we are losing water from our holding tank. It is dripping very slowly from a pipe that come out the underbelly of the camper.

Before I try and fish around the tank, I was hoping someone could tell me the mechanics here...The fresh water tank is a pain in the neck to get to as it sits way back under the bed.

Is there some sort of pin or shut off valve that allows you to drain the tank from the bottom? I'm assuming so and hoping it's a simple repair.

Thanks!

The bottom of my fresh water tank has a petcock type valve to drain it.

It looks like this: https://www.ebay.com/itm/Petersen-Mo...V/133402766078

I have no valve. It's literally some plastic tubing with foam insulation around it to hold it in place.

Everything under the xt276 is exposed 'cause no insulation or underbelly covering so easy access/view all systems.

I'm sure someone will be along soon that has a 189 to give you more specifics.

We have a different model but our drain valve was inside, down on the floor, next to the tank.

Did you ever find it? I had the same issue. If you lift up the mattress there's a trap door on the left side which leads to the tank. The freshwater tank has a valve (right by the floor, closest to center of camper) you can turn that changes the water from draining out of the bottom like yours is doing, to going to the sink, etc. Just turn that valve and you'll be all set!
