The EZLEVEL prevents premature piping failure as well as
boiler scaling by replacing that troublesome relic, the ball-float valve.
The ball-float valve maintains the level of water in the return tank.
Ball-float valves are known for leaking and/or failing open. This allows
fresh water to continuously leak into the return tank. This fresh water
contains lots of free oxygen which combines with carbon dioxide to create
carbonic acid. Carbonic acid destroys pipe work and boiler internals. In
addition this continuous leakage of fresh water dilutes the boiler compound
resulting in scale formation.
