[VAC] Re: Water Lines

["Dick Parins" <2867@xxxxxxxx>]

Hi Kathy,

I am replacing the water tank and pump in our Bambi. The instructions with 
the new Shurflo pump say you must use flexible plastic tubing within one 
foot of the pump on both sides.  They say NOT to use stiff plastic in that 
area which I take to mean PEX.  I have installed a new city connection 
through the floor into the belly access door with a backflow preventer in 
the coach to keep the city water pressure off the tank.  The pump will 
mount between the tank and this backflow preventer. I will use nylon 
reinforced plastic tubing which is rated at 200 pounds per square inch for 
everything upstream of the backflow preventer. This is a very short distance 
in our small trailers.  I will continue with copper for everything downstream 
of the backflow preventer.  I could use PEX downstream but I like working 
with copper, have the tools and the sweated fittings are reasonably priced.  
In my trailer the lines all have a pitch to a drain so it should not be too 
tricky to winterize (I hope).  I plan to use the original fill spout on the 
front of the trailer and I think I've come up with a bug proof vent arrangement.

Good luck on your plumbing project.
