An inline chlorinator is one that plumbs
right into the piping on the return side, after all the equipment. It is
relatively easy to install because you just have to cut the piping and glue
it in just like a coupling or a tee.
The downside to this type of chlorinator is
that it frequently has flow problems. The chlorinator has a "scoop" which
grabs some of the water and forces it up and into the chlorinator.
The problem is that sometimes the flow is not
adequate to push the water up and into the chlorinator and establish a
sufficient flow to properly erode the tablets. In addition, the chlorinator
tends to build up an air pocket in it, and tablets do not dissolve in air
(obviously), and only the bottom tablet might dissolve, thereby greatly
reducing the chlorine output. You also run a higher probability of
developing chlorine gas inside the unit.

Rainbow off-line pool chlorine feeder
An
off-line chlorinator is one which is free-standing and has tubing that
connects it to the pool system. The one pictured to the right is a
Rainbow 300 off-line chlorinator. This is the one we most often
recommend for home pools.
Because of the way this one is plumbed, it
does provide better water flow through the unit than the Rainbow 320 inline
feeder. This unit is still susceptible to developing an air pocket because
if there is air in the line, it will rise to the top of the unit (because
air is lighter than water), and an air pocket will develop.
The
Rainbow 300-29x is more of a commercial grade chlorinator with much
higher capacity than the 300 model. The 300-29x has larger tubing and a
larger chamber, but the greatest difference is that the water exits the
chamber at the top, so that any air build up is purged out almost
immediately. The 300-29x has the best flow of any of the chlorinators. The
illustration at the left shows the design of the unit, but the unit is
actually about twice as tall as the 300 model and has twice the capacity
(approximately).
Control Valves can be a bit of a
problem on the offline chlorinators because you have non-filtered water
going into the chlorinator. Grass and other debris can get stuck in the
valve and keep it from operating well. If the valve will not fully open or
close, then it probably needs to be replaced.
