Chemical feeders are great for providing a hands-off approach to sanitizing your pool water. Most of the time, the feeder is loaded periodically instead of daily. However, if the feeder is improperly installed, harm can be done to the system. One important tip is to try to correctly position the injection fittings. Whenever you have a dry chemical feeder, you want to pull water from a place in the system where the highest flow occurs so that the chemical can dissolve properly before it is sent back in to the pool or spa. Instead of trying to divert the water immediately after it goes through the pump, you should place the first injection fitting immediately following the filter. This grants the rapid flow that is needed to dissolve the chemical, while ensure the water is clean and free of clogging materials. Ensuring the proper installation of your chemical feeder is the key to successful sanitizing. A helpful tip to ensure that you properly install your feeder is to inject the chemical in the right place. This might sound silly, but studies have shown that this is a trouble area for those installing the feeders. The second fitting is where the diluted chemical enters the pool. If the solution goes to the wrong place it can cause damage to your pool. To prevent yourself from putting the solution in the wrong area, inject the chemical at the very end of the equipment line so that the chemically treated water enters the plumbing just before it returns to the pool or spa. It is also important to remember to check the valves. While proper feeder placement helps protect the circulation system components from corrosive chemicals, the installer is important too. A check valve should be placed between the heater and the point where the treated water is introduced. This ensures that the diluted chemical solution doesn’t get into the backwater—which would cause damage. These check valves help block chlorinated water from entering once the pump shuts off. If you want to be sure that this happens, you can also install an outer check valve as a backup.
