[VAC] new member with foul smell

[slima <slima@xxxxxxxxx>]

HI  Everyone!
I am the new owner of a 22' 1955 Airstream trailer and also a new member

of this discussion group.  I live in central Texas.

I am having a problem with a very foul odor from the faucet when hooked
up to a fresh water supply.  The odor is most intense when I first turn
on the faucets and seems to fade as I let it run.  The very next time I
turn it on, however , the smell is back.  It smells like sewage.  If I
put that water in a container , it still smells like sewage and so I am
certain it's not coming from my drain.

Has anyone experienced this problem?
Should I conider replacing all the pipes?
Could there be a simpler solution?

Thanks,
Suzy
