Filling fresh water tank

[tearza]

I purchased a used Motorhome 6 Months ago. I just started to check out the fresh water system. I started filling it up and I get a lot of water draining underneath. I checked it out and it is coming from a two inch pipe. What is this pipe for? Is it the overflow on the fresh water tank

tearza,


Surely, you will need to tell us what motorhome you have and where the 2" pipe is.

It sounds like the water tank drain is open. I don’t know about the avalanche, but on our 01 the overflows are a smaller diameter hose. On ours there is a handle on the front side of the drivers side storage compartment behind the propane compartment that opens and closes the drain valve.

Also not familiar with the Avalanche. The 2” pipe does sound like the drain pipe. The overflow tubes are 1/2” PEX, one in front one in back. Can you visibly see the tank to confirm the water level?

….As you probably know by now, the Avalanche was a very low production run by WRV, so std. Alpine owners don't have much, if any, first-hand experience to help you. Your situation sounds like the dump valve on the water tank is open....early model Alpines have a 1 1/2" dump slide valve with a cable remotely attached to a T-handle--located on the side wall, in the basement, just behind the propane tank, on the driver's side.
