How To Decide Whether You Need An In-line or Off-line Chlorinator

Step 1

What type of pool do you have? Determining whether the chlorinator is for an above ground or in-ground pool will greatly narrow your search.

Step 2

Determine the size of your pool. Calculating the number of gallons your pool holds will factor in when choosing how big or small your chlorinator needs to be in order to keep your pool healthy. Click here to determine the number of gallons in your pool

Step 3

Brand- Do you your research. Bigger names are slightly easier to maintain for the simple fact that it is easier to find replacement parts if necessary, as opposed to having to replace the entire chlorinator. Also, check to see if the chlorinator comes with any additional features such as the self- cleaning option.

Step 4

Next, you will need to decide whether you need an in-line or off-line chlorinator. It simply comes down to the question of whether or not you have room to place the chlorinator in-line with the rest of your equipment. In-line chlorinators are connected directly after the filter (or heater, if you have one) and should be the last piece of equipment before the water is returned back to the pool.

Step 5

Off-line chlorinators are typically used when an in-line chlorinator cannot fit into the existing system. The off-line chlorinator is connected through a bypass line off-line from the rest of the equipment.

Step 6

Don't forget to check the chlorinator capacity. Ensure the size of the chlorinator you chose is sufficient for your gallon size pool.
