Re: [A/S] Sealand vs Thedford toilet

["D. Reilly" <dmr@xxxxxxxxxxx>]

I have a Sealand in my 1963 Airstream.  This type of toilet has a plastic
flush valve.  It will freeze at the drop of a hat!!  I have replace it at
least 4 times over the last 8 years at $50.00 a pop.  I finally plumed in a
metal ball valve in the closet next to the toilet.  Got rid of the expensive
Sealand valve all together.

On  the other hand, my first SOB trailer had a garden variety Thedford
toilet that never froze up.  I think it has a vacuum break valve in it that
drains out the water after each flush.

 Hope this helps.
