Pentair 98209800 High Flow Manual Relief Valve Replacement Pool and Spa Filter

This Pentair high flow manual relief valve is a perfect replacement part and works exactly as intended. Installation was quick and simple, and it fit my Pentair filter housing without any issues. The build quality feels solid, and the valve opens and closes smoothly with no leaks. It makes bleeding air from the system easy and efficient, which helps keep the filter running at peak performance. It’s a small part but very important for proper filter operation, and this one does the job well.

This Pentair product was exactly as I needed and works excellent. As usual Amazon service was exceptional.

This seems to be OEM and was very easy to install. Maybe 5 minutes? The old relief valve was the original that came with the filter housing which is about 5 years old. The problem I was having is the valve would open just fine but when closing it, it would not “lock down”. Meaning it simply would not turn all the way so that the tab went into the flat part giving the feeling that the valve was completely closed and would not work itself open due to vibration or pressure. I assume some bit of debris must be lodged in there somewhere causing this issue but it’s easier to just replace the entire valve. New one works as designed and locks down as it should. No more concern that it will “pop itself” open and spew water everywhere.

Works great!
