Star-Rite System 3 Filter Air Bleeder Upgrade!

One of my favorite cartridge filters is the Sta-Rite System 3 filter. They also make this in a De filter version and it is probably one of the most durable and longest lasting filters on the market. But the weak point of this filter is the very outdated and poorly functioning air relief valve. For such a large filter the air bleeder is very small and pathetically weak. But there is a simple $30 upgrade that you can make that will turn the air relief into a real beast.

Sta-Rite and Pentair are the same company now and Pentair makes a series of cartridge filters known as the Clean & Clear and Clean & Clear Plus.  They make an air relief valve that is awesome, and wouldn’t you know it, it fits perfect on the System 3 filter. Pentair 98209800 High Flow Manual Relief Valve Replacement Pool and Spa Filter. You would simply remove the entire air relief on top of the Sta-Rite filter and insert the 98209800 right in its place.

You don’t need any actual tools to do this, just an adjustable wrench and some Teflon Tape for the pressure gauge. Make sure pool timer is off and will not come back on during the process. Remove the old air relief assembly on top of the Sta-Rite filter and then thread in the 98209800, no Teflon Tape needed at that threaded area. Then apply Tephlon Tape to the pressure gauge and thread it into the Air Relief (after you remove the plastic plug). Now when you go to let air out of the filter it will take a matter of seconds and all of the air will be evacuated rapidly.

It is as simple as that and your Sta-Rite System 3 filter has been upgraded.  It is important to let the air out of the filter after cleaning the filter and after you clean the pump basket. This helps the pump prime easily and prevents air from getting trapped in the lines after the equipment turns off. You may notice air bubbles coming out of the return lines if you don’t do this. The 98209800 Relief Valve will make sure no air is in filter and I recommend this upgrade at your earliest convenience.
