The difference between an inline and an offline chlorinator lies in the systems that they are plumbed into your swimming pool lines. While your offline chlorinator is ideal for retrofitting existing pool systems, the inline chlorinator is suited for a more permanent installation into the return line of new or existing systems.

There are plenty of considerations to factor in when picking the right inline/offline chlorinator, which include water flow, difficulty to install, ease of maintenance and even the type of chlorine tablets to be used.

Despite such factors, both chlorinators will need constant refills or replacements. We can address this concern by creating this category so that you now know where and how to get the genuine replacements you need for your chlorinators that will not cause damage to your pools or spa.

The first component we have in this list is the: CL2002S HAYWARD Chlorinator In-Line 2" SKT. This may be the component to replace should your chlorinator no longer hold the maximum limit of bromine or trichlor tablets that it intends. If your off-line chlorinator's dial control valve will no longer allow easy feed rate adjustments, then there might also be a problem with this part.

When looking for the right chlorinator you need, see the level of water flow rate you need. Some in-line systems with low flow rate can only dissolve chlorine tablets of smaller size. If your pool or spa is larger and requires more through chlorine dissolution, make sure you pick the better water flow features that an offline chlorinator provides.

If easy-installation is a priority, make sure you pick an inline cholorinator, though. You can install it simply by cutting into the main pipe that's connected with the filter and the set-up is now done.
